3W International introduces complete propulsion systems for the first time at Xponential 2016

German engine manufacturer 3W International is introducing its design for complete propulsion systems for the first time at the leading trade show in New Orleans. Moreover options will be introduced concerning special mounting plates for mounting different engines on the same engine chassis or the identical firewall.

"The market is demanding complete engine systems and individual solutions that nonetheless permit a high degree of flexibility", summarizes Karsten Schudt, managing director of 3W International, when asked about the results of the latest customer meetings. "That means customers are increasingly looking for engines with all of the auxiliary systems such as generators, starters, air-duct systems, engine suspensions, and silencer systems", continues Schudt. 3W International will consequently exhibit a complete propulsion system for illustrative purposes at the exhibit stand.

"We can deliver our engines to our customers ready for use. That means the engines are completely equipped and delivered with ECU, silencer, starter, generator, engine mount, and air-duct systems. We can also deliver the propeller if the customer so desires. The propulsion systems leave our factory in Hesse tested and are therefore "ready to use". The customer himself basically has to complete only three tasks: unpack, install, and take wing", says Schudt descriptively of 3W International`s complete-propulsion concept. Here every propulsion system is tailored to the customeras desires and needs.

"So we`ve got to work very closely together with our customers. This means that we must be involved in UAV development early in the project phase" Schudt clarifies. Because even if the customer decides in favour of a standard flight body, the application`s take-off weight and the flight performance depend upon the UAV`s application and performance targets. Engines featuring various performance capabilities, which are installed differently due to their weight and side, are therefore in part necessary with the same flight body. "So we`ve got to be involved early on in the project, because the entire propulsion system is tailored to the flight body and the customer`s wishes", explains Schudt.

This concept has been introduced to date only to customers in Europe and Asia. The response was quite positive, and the first orders were placed. It`s because the benefits are clear to see: In such a co-operation the propulsion system is optimally aligned with the aircraft but also with the intended use, and the customer can draw upon 3W International`s expertise and years of experience. "In this case the 30-plus years of experience of our developers from model building are paying off, because we know from that how we put engines, auxiliary systems, and the aircraft together into a unit that perfectly satisfies the customer`s needs", Schudt makes clear.

An additional possibility of the use of different engine types is specially developed engine support systems, which enable different engines to be mounted on one and the same engine chassis or on a firewall. "Some of our customers use one and the same UAV type for different application purposes. In that connection it happens that engines with different performance parameters also have to be used", explains Schudt. Different engines can in part be fastened thanks to the special mounting systems. Different engine types can thereby be used in the same flight body without big development projects.

"We repeatedly encounter great interest with these simple solutions in customer meetings. That shows us that the market is also increasingly moving in a field where increased efficiency, cost savings, and short development cycles are coming to the fore with the development of UAVs. Financial indicators and core data are becoming increasingly important when it comes to the development, construction, and use of UAVs. Our flexible modular-design system allows these individual customer needs to be optimally met. So 3W International will also continue to work on the concepts that accompany and support these developments on the customer side", says Schudt in summary.

3W International is located in hall 1, booth 567 at AUVSI.

3W International GmbH presents an expanded range of engines at AUVSI`s Xponential 2016 in New Orleans

3W International is exhibiting a portion of its engines for the first time in 2016. This is due to strong demand from the civilian applications area. All engines from 3 HP to over 60 HP can be provided with both carburettor and alternatively with electronic injection. Fuel consumption can thereby be reduced due to more exact consideration of all of the operating parameters. The power density can be increased through better mixture treatment and the engine`s regulation can be better controlled at various engine powers. This is especially true during warm-up.

Moreover the team from 3W International analysed the last trade fair and the conclusion was clear: the market demands complete engine systems. "That means customers are increasingly looking for engines with all of the additional systems such as generators, starters, cooling jackets, engine mounts, and silencer systems", confirms Karsten Schudt, managing director of 3W International GmbH. 3W International will exhibit a complete drive unit at the exhibit stand for illustrative purposes.

3W International is also introducing engines for hybrid applications in addition to the complete drive units. The hybrid drive has moved increasingly into the foreground in recent months. "Most of the inquiries here relate to the UAVs` commercial or civilian use", confirms Schudt. The internal-combustion engine takes on the most varied tasks in these cases. For one thing it can be used for vertical starts in which high performance is required depending on the application area. The internal-combustion engine is used in combination with a generator to supply power to the electrically driven rotors, which move the flight object after take-off. Furthermore the internal-combustion engine fills in when energy stored in the on-board batteries diminishes.

An additional exhibit completes 3W International`s exhibit stand. The customer PowerVision GmbH is exhibiting the DRAGONFLY DF M35 RAPS helicopter. PowerVision GmbH, with headquarters in the immediate vicinity of Frankfurt a.M., Germany, is an internationally active company specializing in the development, production, and sales of RPAS helicopters. The DRAGONFLY DF M35 is equipped with the 2-cylinder, 14.5 kW, 3W-170 XiB2 TS CS flat engine with double ignition from 3W International.

3W International is located in hall 1, booth 567.
