SP-180 SERIES (Wankel engine)
The Sky Power Wankel Rotary UAS Engine is a hybrid electrical engine with a compact design and an outstanding power-to-weight ratio.
Therefore, the engine allows a higher payload capability. With the hybrid-boost power, additional 15KW, depending on on-board battery capacity, are optionally available. This additional power improves take-off performance significantly.The SP-180 SRE hybrid can run with gas or Heavy Fuel (HF). Sky Power offers a standard fuel injection and an optional high-pressure fuel injection (HPI).
The cooling of the engine is guaranteed by water cooling of the housing and oil cooling of the rotor (active cooling), allowing reliable operation in certain challenging environmental conditions.
