3W-International Heavy-Fuel Aircraft Engines for Naval Applications

3W International

3W-International supplies patented next-generation heavy-fuel (HF) engines for helicopters, unmanned fixed wings, and hybrid unmanned aerial vehicles (UAV) in the naval industry.

Two-stroke aircraft engines for naval applications

3W-International offers a wide array of customisable two-stroke engines in one, two or four-cylinder configurations.

All engines are available as a twin-spark (TS) version for increased safety and reliability.

Available with auxiliary systems, carburettor or electronic injection, 3W-International engines are custom-made according to the required performance parameters, or the used aircraft or fuel type.

The company also offers a range of complete propulsion systems ready for immediate deployment.

Lightweight Wankel engines for increased field payloads

The 3W-International 180 SRE Wankel Rotary UAV Engine is a compact hybrid cycle engine, which is lightweight and offers a high power-to-weight ratio, enabling higher payloads during field operations. With the hybrid-boost power capabilities, an additional 15KW simplifies its lift-off or acceleration processes.

The engine can be powered using gas or HF, so the company also supplies a standard manifold or a high-pressure injection (HPI).

Muffler systems to reduce engine volume

3W-International’s mufflers use a type of turbine wheels that are permanently installed in a cylinder to increase performance while simultaneously minimising the volume.

Individual, wheel-mounted fins are organised in defined angles to level out the exhaust gas’ sound wave.

Innovative technologies for optimal TBO

3W-International specifies time-before-overhauling (TBO) timeframes that vary from 400-600 hours, depending on the conditions of use, engine maintenance, and the RPM range.

Optimal performance is possible if engines are driven at moderate speeds and regularly serviced.
