RCV Engines, a leading producer of compact multi-fuel propulsion systems tailored for unmanned aerial vehicles (UAVs), has announced the integration of their DF70LC heavy fuel engine into a newly developed unmanned helicopter by Sentinel Unmanned.
Explore the complete case study here.
The Sentinel Longreach 70 UAV is a compact rotorcraft engineered for extended missions across diverse environments, including challenging terrains and maritime settings. Sentinel aimed for an impressive endurance of up to 8 hours, a payload capacity of 6kg, and the ability to operate on heavy fuel, ultimately choosing RCV’s DF70LC engine as the foundation for their platform.
The DF70LC propulsion system from RCV is a 70cc twin-cylinder engine that boasts liquid cooling and an outstanding power-to-weight ratio. The design of the airframe and the integration of the engine were executed in close partnership with RCV to ensure that the design objectives and aircraft specifications were fully achieved.
Additional benefits of the DF70LC engine include:
- optimized mixture preparation thanks to a patented rotary valve mechanism
- Remote ignition capabilities using various fuels such as JP5, JP8, and Jet A1
- Integrated heaters and effective combustion processes
- Extended mean time before overhaul (MTBO) of up to 150 hours for rotary-wing applications
