Heavy Fuel and Gasoline 4-Stroke UAV Engines
RCV Engines is a specialised manufacturer of small multi-fuel engines for unmanned systems.
RCV’s patented revolving valve combustion system delivers excellent power-to-weight and operates equally well on both gasoline and HF (Heavy Fuel:- Jet-A1, JP5, JP8). This makes it ideal for small fixed-wing UAVs, VTOL multi-rotor UAS and hybrid/power generation applications.
The RCV is in full production and is proven HF compatible. The engine is operating successfully on HF in many applications around the world.
The robust RCV combustion system ensures that starting, handling and power are excellent, and are unaffected by ambient conditions, altitude and variations in fuel composition. RCV’s engines provide long MTBOs of up to 150 hours for rotary-wing UAVs, 250 hours for VTOL platforms and 500 hours for fixed-wing drones.
RCV engines are supplied complete with exhaust, fuelling system, ECU and generator mounts, and can also be supplied with the following options:
In addition we offer a design facility which allows us to work with you to understand the requirements fully, develop the specification and provide a complete package that meets your needs. This service also extends into the integration of the power-plant into the platform ensuring optimisation of the system.
The DF70 is a high-performance 4-stroke twin-cylinder UAV engine designed to military specifications for the aerospace market. Suitable for both VTOL and fixed-wing unmanned aircraft, the engine offers superior fuel economy, quiet running and excellent starting reliability.
With a capacity of 70cc and a power output of 4.2kW, the DF70 also features a boxer configuration for minimal vibration, as well as rotation options for either pusher or tractor configurations. A “limp home” mode offers the ability to run the engine on just one cylinder.
