3W-International’s performance partner Sky Power and A-techsyn are introducing the first Sky-Power-driven VTOL

A-techsyn — manufacturer of VTOLs, fixed-wing UASs, target-acquisition drones, and communications and autopilot systems — will introduce the first VTOL equipped with one of 3W-International-performance-partner Sky Power’s engines at Xponential 2018 as part of the 3W-Interntational exhibition stand. A SP-110 FI TS based on 3W-International GmbH’s 110 ccm model is involved here. The engine can be deployed both as vertical drive and for power generation.

A-techsyn Ltd. is a company from Shannon, Ireland, which has been intensely occupied in recent years with the development of UASs and the associated communication and flight systems. The CGT45-SLT vertical take-off aircraft was equipped with the retrofitted engine as part of the collaboration with 3W-International and Sky Power. “The CGT45-SLT has been used in Turkey for some time now. However, we were looking for a new engine concept in order to increase the range and pay load”, explains Gokhan Celik, managing director of A-techsyn. That’s why the Irish company contacted 3W-International. “The standard 3W-110i B2 TS engine’s performance parameters would also have sufficed, but ultimately the choice fell to the SP-110 FI TS from Sky Power”, according to Karsten Schudt, managing director of 3W-International.

The CGT45-SLT is a 4.5 m wingspan, T-tail UAV. It uses electric powered motors for take-off and landing and does not require a runway or catapult. The VTOL can take off from a table and land with high accuracy on a 5 m × 5 m surface. It is a composite airframe with 4 kg payload capacity. At the basic set-up, CGT45-SLT uses 3 separate communication systems for datalink, video-link, and the FPV. The datalink system operates at 900–922 MHz, FPV at 1.2 GHz, and the video-link at 2.4 GHz. The video-link uses IP communication and 128-bit SSL encryption to secure the data transferred. Video and data may be broadcast if desired. The CGT45-SLT has a 50 kg MTOW (including payload). It can be operated by only two people. The CGT45-SLT is controlled by A-techsyn’s flight controller AvionicsMini. This flight controller is using CAN BUS interface to communicate with the new ECU030 by Sky Power.

Beside the ECU030, the SP-110 FI TS is equipped with the new HKZ215 ignition from Sky Power too. “Thanks to the two new systems, the engine can be tuned exactly to environmental conditions as well as to the customer’s wishes”, explains Karl Schudt, managing director at Sky Power. The system has four ignition channels with two separately settable injection nozzles. Pump pressure is regulated electronically. A cold-start function of the engine is possible without further ado. The automatic controller adjusts the fuel mixture to the current cylinder temperature, air pressure, and exterior temperature. The high-performance HKZ system was developed for significantly greater ignition powers. The engine’s overall fuel efficiency is thereby enhanced and the exhaust values improved. “With the new ignition and injection system, we achieve better power performance in 3W engines, plus a significant reduction of fuel consumption”, explains Karl Schudt.

In addition to the CGT45-SLT, A-techsysn will exhibit its own autopilot, PilotUS, as well as further systems developed for its own flight systems, on the 3W-International stand during Xponential.

3W-International, Sky Power, and A-techsyn are located at stand 2210.

3W-International remains unaffected by 3W-Modellmotoren’s filing for bankruptcy

The executive management of 3W-Modellmotoren GmbH, which acted as production service provider for 3W-International GmbH, filed for bankruptcy during the past week. For this reason, Karsten Schudt, managing director of 3W-International GmbH, is making a statement that the leading engine supplier for UASs is covered concerning this development.

“Both companies were independent of one another. Nonetheless, the decision of 3W-Modellmotoren’s executive management didn’t catch us entirely unprepared”, reports Karsten Schudt. During the past months, Schudt and his employees became aware that some of 3W-Modellmotoren’s executive management had their eyes on other corporate goals and were no longer interested in regular deliveries to 3W-International. No solution could be reached even after copious discussions so that 3W-International saw itself compelled to establish new production options. In this context, Sky Power GmbH was founded in early 2018 as performance partner and as its own production service provider.

“We were informed about the bankruptcy filing by 3W-Modellmotoren’s executive management. We maintained silence about the filing, but this week we received the first calls from our customers about the extent to which this bankruptcy impacts us. That’s why we saw ourselves compelled to make a public statement about this development”, Schudt continues. Since the two companies are independent of one another, this development doesn’t affect 3W-International. The expansion of Sky Power GmbH will continue as will further development of engines and auxiliary systems.

An in-house production building, into which two new test stands are also being integrated, has been rented for this purpose in the greater Frankfurt area. Production is being established and implemented under the guidelines of ISO 9001. “We’ve also conducted talks with our long-standing suppliers and have been able to retain them all for the long term.

The extent to which 3W-International will be able to support 3W-Modellmotoren’s customers with spare parts and maintenance is unclear at the moment. “We’ve first got to wait for the bankruptcy filing. Furthermore, we have a different engine portfolio than 3W-Modellmotoren because our engines aren’t orientated towards hobby use. We can ultimately only guarantee spare parts, service, and consulting if the engines were demonstrably delivered by 3W-International. That’s why we can only urgently advise against purchasing 3W-International engines from third parties not belonging to 3W-International Sales”, explains Schudt. 3W-International Sales participants can be requested from 3W-International.
