In the past few weeks, 3W-International GmbH has gone through some turbulent times that brought about many new developments and changes. These tumultuous times culminated in a very successful Xponential 2018. Karsten Schudt, Managing Partner at 3W-International GmbH, has now commented on these developments.

In the weeks leading up to the Xponential, there had been many changes around 3W-International: the new production partner Sky Power, new products, new sales staff in Europe and North America, and also a changed presence on the Xponential. How did the market respond to these developments?

Karsten Schudt (KS): There have indeed been many changes in our environment, some intended, some unintended. Nevertheless, the trade show in Denver has shown that our customers understand why we had to implement these changes at our company. For us, the Xponential 2018 has been one of the most successful trade shows in our history. Naturally, some people approached us with questions about what was going on, however, we were able to reassure them that we are well positioned for the future and will continue to be a reliable partner for our customers. The market for propulsion units in general is currently on the move.

Are you referring to the filing for insolvency of your supplier 3W-Modellmotoren?

KS: No, not directly. Obviously, this incident prompted some adjustments on our side. However, even here it can be stated that this topic is not really a cause of concern for us as we are well positioned for the future with Sky Power and reliable partners. We do not wish to get involved in all the other speculations around 3W-Modellmotoren as we no longer maintain business relations with the company. But when we look at the market on a larger scale, the insolvency and sale of Hirth was also associated with many changes.

What changes are you referring to exactly?

KS: 3W-International, together with Sky Power, is the last German-owned engine manufacturer. Many new customers contact us precisely since they are looking for a reliable partner who focusses on long-term customer relations. Therefore we expanded the sales area before the trade show, with tangible effects. Nevertheless, our customers also expect technical further developments along the requirements of future markets. With our Engine Kit, which we presented at the trade show for the first time, we have demonstrated that we are more than just a mere engine supplier. The discussions we had with our customers at the trade fair have shown that we are recognized as a manufacturer of complete application-based propulsion units.

After the trade show is before the trade show – which new products will you showcase in Chicago next year?

KS: First and foremost, we have to concentrate on processing and implementing the Sky Power engine line as well as our Wankel rotary engine projects. Add to this more than 100 inquiries originating from the trade show, which have to be attended to. We are also very busy in the sales area. Moreover, we have set up a development plan for the coming 1 ½ years. This means that we will continue to work actively on the further development of each individual engine aiming to make these more efficient and even more reliable. Reducing fuel consumption is the crucial factor in this regard. In addition, our new development department has already come up with some ideas that will be implemented in the coming months. Consequently, we will certainly present new products at the next Xponential – and surely in a less turbulent environment leading up to the trade show.

At AUVSI Xponential in Denver, drones are everywhere. The global community of commercial and military leaders meet up yearly to discover and share the latest in robotics, drones and unmanned systems. This year’s edition focuses on the unmanned economy, lifestyle and the use of drones for humanitarian purposes.

Marc Coen, CCO of Unifly, presents Unifly’s work in UNICEF’s humanitarian drone corridor in Malawi.

Drones are a hot topic and their applications are seemingly endless. Especially in harsh environments, drones can be a lifesaving tool. Drones can help save lives, not only during a sudden disaster, but for daily humanitarian purposes and medical supply chains.

With drones, even the remotest regions can receive lifesaving materials in a matter of minutes or hours.

Unicef’s Humanitarian Drone Testing Corridor was opened in Malawi in June 2017. It is specifically dedicated to the humanitarian and development uses for drones.

The first of its kind in Africa, the corridor serves as a dedicated unmanned flight testing space and allows for Beyond Visual Line of Sight (BVLOS) testing in a territory over 5000 km² and up to 400 meters above ground level.

The corridor has a 40km radius (80km diameter) and is centered on Kasungu Aerodrome (with a runway length of about 1200m) in central Malawi, about an hour and a half drive from the capital city of Lilongwe. Kasungu is home to a district hospital and a variety of rural health clinics in remote areas, enabling the testing of real humanitarian use cases such as the transport of vaccines, medical supplies or blood samples.
Marc Coen, Chief Commercial Officer of Unifly, was in Malawi to set up the first Unmanned Traffic Management system in Africa in November 2017.

Marc Coen travelled to Malawi to set up the UTM system. He explains: “Unifly provides the Unmanned Traffic Management system to ensure safe testing in the drone corridor. In this project, our software platform connects with uAvionix trackers to follow the drones in real-time.

The first test of the UTM System was in November 2017, during a fully autonomous, simulated blood sample delivery flight. The flight testing explored drone applications in emergency medical supply delivery, vaccines and sample delivery for diagnosis, and remote sensing. Drones can carry lifesaving materials, in places where developed transportation networks do not exist.

A small community located 17 km from the aerodrome was chosen because of the health centre located there and the bad road connection to Kasungu. After one aborted test flight, the second try proved to be a perfect, fully autonomous flight to Kasungu airport. The flight took some 16 minutes and covered an actual distance of 19 km – find more information on the flights here.

For us, the biggest challenge was the infrastructure, or lack thereof. Electricity and internet were intermittent, we also experienced some practical issues. The first time we set up a successful UTM system was back in November. However due to technical issues with the tracker, we were not able to follow the drone at that time.

In November, the secondary goal of the test flight was for Virginia Tech to coach students and faculty from Malawian universities how to construct the aircraft so it can be fabricated and operated locally in Malawi for remote medicine delivery and remote sensing purposes.  The drones are made of foam core (poster board) and 3D printed parts to facilitate local production and keep costs low.

At the second UTM test earlier this month, Swedish FlyPulse and Globhe sent out a drone that combines transport with aerial photography. The goal was once again to deliver medical supplies to areas that are hard to reach, with another secondary goal to the mission. Their drone can capture and interpret aerial imaging. This way important information is made available, such as the quality of the roads, the number of houses in each area and the effects of possible natural disasters such as flooding. This drone flight was a lot longer as well, at 66km. For us, the second attempt was more successful because we could follow the drone’s movements on our screen in real-time.

We believe it is very important to build an ecosystem of drone experts locally to ensure that these solutions are sustainable and embedded within the communities it services.”

Juan Jiménez, Director UAS Business Development at uAvionix, says: “As a safety-focused company, the life-saving potential of unmanned systems has always appealed to us. uAvionix is proud to participate in humanitarian efforts such as this one with UNICEF and Unifly. Even in areas with sparse infrastructure, ADS-B can be used both as a surveillance and DAA aid to BVLOS applications.”

Marc Kegelaers, CEO of Unifly, says ” It has been a pleasure to work with uAvionix in setting up the UTM system for the Malawi Drone Corridor. As a world leader in UTM software technology, Unifly seeks to establish world-wide partnerships with the leaders in their field to build comprehensive UTM systems. The cooperation between uAvionix and Unifly is a perfect example of what can be achieved when complementary companies join forces to create an all-encompassing solution.”

About the drone corridor
The Malawi drone test corridor is open to industry, universities, and individuals who can apply and test a potential use case in one of the three main areas as defined below. The drone corridor in Malawi is an opportunity for companies to provide global leadership in the emerging technology field of drones for humanitarian and development work, while simultaneously developing local experience in Malawi.
The corridor will facilitate testing in three main areas:

  1. Imagery – generating and analyzing aerial images for development and during humanitarian crises, including for situation monitoring in floods and earthquakes;
  2. Connectivity – exploring the possibility for UAVs to extend Wi-Fi or cell phone signals across difficult terrain, particularly in emergencies;
  3. Transport – delivery of small low weight supplies such as emergency medical supplies, vaccines and samples for laboratory diagnosis, including for HIV testing.

The corridor is designed to provide a controlled platform for the private sector, universities, and other partners to explore how drones can be used in scenarios that will benefit marginalized communities. All data generated by the flights will be used to inform the Government of Malawi’s plans for the use of drones in multiple scenarios. This is particularly important due to frequent flooding in some areas of Malawi and challenges in transport infrastructure.

The 2-disc hybrid Wankel engine SP-480 SRE hybrid is being introduced for the first time to the professional public at Xponential 2018. 3W-International and Sky Power thus continue the tradition of presenting a new Wankel engine at the leading international trade fair. The SP-480 SRE involves a prototype.

Following the very positive resonance to the 3W-180 SRE, which 3W-International introduced in 2017, the company decided to further expand this engine portfolio. “The customer resonance surprised us at that time. We’ve launched a large number of projects since then with our customers. These projects often revolve purely around the generation of electricity. That’s why we’re now introducing the SP-480 SRE, which can also be used as a hybrid drive”, explains Karsten Schudt, managing director of 3W-International GmbH.

The engine was developed at performance partner Sky Power GmbH, which was also active in other forms in the background during the 3W-180 SRE hybrid’s development. The SP-180 SRE hybrid is a 480 ccm, 2-disc Wankel engine. At 6000 rpm, the engine achieves 70 hp with a basic weight of 14 kg. As with the single-disc engine, the housing and the trochoid are water cooled. An active oil circuit cools the piston. “Both cooling systems are very effective. They don’t need a pump, so they’re virtually maintenance free”, continues Schudt. The engine can be driven with both gasoline and with Heavy Fuel.

The engine is being introduced as a prototype at Xponential 2018 in Denver. “As in 2017, we want to test the market with the presentation of the new engine. We know about the performance level and also the customers for which it makes sense. Now it’s about supporting these assumptions through customer reactions. The customers have confidence in our 1-disc Wankel engine. The reactions show that. That’s why we’re assuming similar reactions for the SP-480 SRE hybrid”, according to Schudt.

3W-International and Sky Power are exhibiting together at booth 2210.

3W-International GmbH’s performance partner is introducing a novel engine construction kit in order to enable still more efficient and performance-optimized engines in future. Using this construction kit, propulsion units can be ideally tuned to the customer's desired performance parameters and application area.

“We’re seeing ever stronger demand for application-oriented solutions”, explains Karl Schudt, managing director of Sky Power GmbH. “That’s why we considered how we could best serve this demand, since each customer favours his own solution. In the past, UAS manufacturers were just interested in getting their flight systems into the air. That’s why propulsion units were often relegated to a subordinate role. This has changed permanently in recent years. Today, UASs have got to fly efficiently and be tuned exactly to their application area”, explains Schudt further. Out of this came the first engine construction kit for UAS systems from Sky Power and 3W-International with which customer- and application-specific propulsion solutions can be quickly visualized and implemented.
The engine construction kit consists of widely different components. At the centre is the basic engine, which can be equipped with both a carburettor and the new injection from Sky Power. To this is added as desired exhaust, silencer, and the new ECU and ignition. The engine can furthermore be provided with an e-drive or generator, which uses a converter to generate electrical energy for batteries and super capacitors — so-called
supercaps.

Super capacitors can be charged and discharged very much faster. Besides, they withstand a lot more switching cycles than rechargeables, so they lend themselves as substitutes for the latter whenever severe switching stress is required. Super capacitors’; application area stretches from provision of the weakest currents for data retention in static memories (SRAM) up into the power-electronics range, thus for instance, as the store of
electrical energy in the KERS system in Formula-1 racing cars. This is also exactly the property required in UAS propulsion units when they’re used as a hybrid system or to feed in energy to enhance the engine’s short-term performance.

All 3W-International engines can be equipped with this e-drive supercap system. The engine can therefore be used as a pure power generator for electrical motors, but also as a combined system in which electrical and combustion energy can be used in combination. Pure usage from combustion energy is likewise possible. The customer’s performance parameters and application area determine the engine’s usage type. “At the trade fair,
we’ll show visitors which modular components are necessary for an electrical emergency system, for direct engine use, for a range extender, and for hybrid applications”, explains Schudt. The hybrid application is being accorded a lot of attention at Sky Power because the demand for such propulsion solutions continues to intensify. “Hybrid drive units are going to be the propulsion source for unmanned systems in future”, continues Schudt.

The engine construction kit necessitates the propulsion manufacturer’s early involvement in the customer’s project. Here not only the right components are sought out, but they’e also got to be tuned to one another.

Thus for instance, the silencer must be orientated towards the basic engine’s cylinder volume in order to prevent a performance-diminishing backing up of exhaust gases. The e-drive must be selected based upon the desired electrical power and the ECU must be calibrated to the propeller used, the desired flight performance, and the flight surroundings. The same applies to the use of carburettors or injection. In addition, the customer requirement decides about the use. For instance, cost-optimized carburettors make sense for target drones, whereas a carburettor must be discouraged in the case of performance-optimized engines.

“Many details must be clarified with the customer before initial engine assembly. So we’ve got to maintain tight information exchange with the customer. After all, he’s getting an individualized product that has to conform with defined parameters. That’s why we’ve invested in additional in-house test systems in order to demonstrate the engine performance that the customer wants”, Schudt continues.

The engine construction kit is being introduced in 3W-International GmbH’s booth 2210 at Xponential 2018.

PHILADELPHIA – May 9, 2017Rajant announced today advancements in its Kinetic Mesh® Wireless Network technology that will power in-air mesh networks, enabling drone manufacturers to strengthen drone-to-drone and drone-to-ground communications. Kinetic Mesh delivers communication and video backhaul capabilities, supporting public safety, border security, search and rescue, and site survey applications, among others.

One of the first to capitalize on these latest advances is xCraft, a mass-market developer of innovative drone technology and company that received investments from all five “sharks” on SharkTank. Coupling Rajant’s onboard intelligence with its new x2i Hybrid VTOL (vertical take-off and landing) drone will allow users to fly in single, swarm or tethered configurations, opening new doors of commercial opportunity.

“Rajant’s network technology now makes it possible for one pilot to operate many x2i aircraft concurrently, with flight times of 45 minutes,” said Bob Schena, Rajant Chairman and CEO. “We’re pleased to partner with xCraft and bring more intelligence, mobility and autonomy to UAV communication infrastructures. Building upon our recent selection as the network infrastructure provider for the Sharp INTELLOS™ Automated Unmanned Ground Vehicle (“A-UGV”), x2i enables Rajant customers to cover greater aerial distances while supporting various drone payloads for video, LIDAR and chemical detection.”

A VTOL drone that combines the hovering ability of a multirotor with the attributes of a plane, x2i leverages Rajant’s InstaMesh® routing software to deliver broadband over VTOL aircraft capable of transmitting applications up to 300 Mbps for such sectors as public safety, oil and gas, mining, forestry, agriculture, and homeland security. InstaMesh software also minimizes the amount of time necessary to configure the drone and the Rajant network for flight.

“Unlike other drones, the x2i takes off and lands vertically, and transitions to forward flight using its high-efficiency wing,” said JD Claridge, CEO of xCraft. “Its capabilities, together with Rajant’s wireless network infrastructure, open the door to hundreds of commercial applications that can benefit from high-speed, long-range flight.”

The VTOL aircraft can fly farther and faster than any other multirotor in its class, with the ability to fly for 45 minutes at speeds up to 60 mph while carrying as much as 1.5 pounds of payload. No longer do organizations need to choose between the hovering precision of a multirotor and the speed and endurance of a fixed wing; the x2i meets both criteria.

xCraft will show the x2i Hybrid VTOL drone today through May 11 in Rajant Booth No. 1908 and its own Booth No. 345 at AUVSI XPONENTIAL in Dallas, the largest global community of leaders in drones, intelligent robotics and unmanned systems shaping the future of industry.

Since the increased demand for complete drive units the requests to 3W-International GmbH for individual services has also increased. In the months following the Xponential Show in New Orleans in 2016, many customers have enquired about individual services. “As a result, we have decided to offer these individual services internationally to our customers as an additional product from our company”, explained Karsten Schudt, Managing Partner of 3W-International GmbH.

3W Engineering Services offers its customers a comprehensive service catalogue all around the development of individual drive concepts, the optimization of existing drive trains as well as the integration of drive systems in the UAS industry. Thereby the customers can rely on the more than 35 years of experience that the 3W-International GmbH experts have gained in the development of engines and their auxiliary systems.

One of the focal points is the design of individual drive solutions, including the subsystems, based on the customer specifications and the performance characteristics to be achieved. In the process, the 3W-International GmbH specialists not only undertake the hardware and software development, but also the development of the electronics including their manufacture. The prototype assembly together with the engine tests as well as the start of series production are likewise undertaken as the next steps.

In addition, the Hessian family business offers various engine tests for 3W and third-party engines on its test benches. These include not only the general performance measurements of combustion engines but also the thrust and power measurements, exhaust emissions analysis, engine indexing, endurance testing, blower, water and oil-pump analysis, purge image analysis, cylinder head measurement and load change calculation. EMC measurements and climate and temperature tests are likewise possible. The test benches of 3W-Internatinal GmbH can also be hired by customers on a daily basis.

Finally, 3W-International GmbH offers consultation during the integration of combustion engines into unmanned aerial systems. This, however, requires certain framework conditions. 3W-International has to be part of the project team, on the basis of signing a Non-Disclosure Agreement (NDA). Preparation of a requirement specification for project coordination and definition of the requirements with dedicated tasks is a must, too. Beside this, an early know-how- and consultancy-transfer regarding the integration of propulsion technology and individual components is needed.

Information about the 3W-Engineering Service will be presented by 3W-International on Stand 3131 at the Xponential Show 2017 in Dallas.

Bad Homburg, Germany, April 20, 2017.  “In the past, many interested parties at trade fairs and congresses have asked us about Wankel engines” recalled Karsten Schudt, managing partner of 3W-International GmbH. For this reason, Schudt and his development team decided to expand the product segment with Wankel engine technology. In doing so, it was clear right from the start that the new engines had to fit in with the philosophy of 3W-International GmbH.

“We wanted a high-quality, fuel consumption-optimized engine which would demonstrate an outstanding power-to-weight ratio”, recalled Schudt. The 3W-180 SRE Hybrid has 180 ccm and as a short engine weighs 6.8 kg. In the high power version, at 7500 rpm it delivers 38.5 hp (nominal power 28 hp at 6000 rpm). From this there results a power-to-weight ratio of 5.66 hp/kg, with a fuel consumption of 340g/KW at full load.

The weight rises to 9.5 kg when the engine is fitted with an electric motor (starter generator). The generator also charges the super capacitors which turn the Wankel engine into a hybrid drive. Super capacitors are well-suited to hybrid applications in aviation due to their weight and fast charging and discharging behaviour.

“We are very proud that we are able to offer our customers an additional service with this modern and sustainable technology which is available at short notice” Schudt was pleased to say. The hybrid Wankel engine can feed 15KW, depending on the capacity of the storage system, into the system for a time (for example, 30-60s). This additional power can be used when starting a helicopter or for the acceleration of a fixed wing aircraft. “Thus our customers always have a power reserve on call”, confirmed Schudt.

The 3W-180 SRE Hybrid is equipped with two independent cooling systems. A water cooling circuit undertakes the cooling of the engine housing, a second, oil cooling circuit, undertakes the internal cooling of the piston. This is a fundamental prerequisite for a drive system in aviation applications for which continuous power is also a fundamental prerequisite. Here the thermal stability, which gives added value to the 3W-180 SRE Hybrid, is of crucial importance.

In a further expansion stage, the Wankel engine can also be equipped with two drive pulleys. Through the doubling of the swept volume, the power of the naturally aspirated engine is doubled to 76 hp in the high performance variant with a short weight of 10.5Kg. This engine variant is also intended as a hybrid version. In the future, a variant with a turbocharger which is primarily intended for height compensation will also be offered.

“We can also supply the Wankel engine as a complete drive unit similar to our two-stroke engines. This means that the customer receives the engine equipped with all additional systems completely in accordance with his individual requirements”, explained Schudt.

In accordance with the engine philosophy of 3W-International, the 3W-180 SRE Hybrid can be used as a petrol or as a Heavy Fuel (HF) engine. As an HF engine, the fuels JET A-I, JP-5 or JP-8 can be used. “For the HF versions we provide high performance fuel injection which leads to a further reduction in fuel consumption”, explained Schudt. For petrol operation, intake manifold injection is provided for the fuel injection.

At XPONENTIAL in Dallas in May, 2017, 3W-International will present the hybrid Wankel engine for the first time to the specialist audience on Stand 3131. “We are looking forward to being able to introduce a new engine to our customers which, from a technological perspective, offers unparalleled advantages in terms of fuel consumption, drive performance and reliability”, said Schudt looking into the future.
