Initial development of a multi‐fuel stepped piston engine for unmanned aircraft application Available to Purchase

The SPV580 stepped piston engine has been designed and developed for UAV application. The gasoline engine produces a minimum of 30kW at 5000 RPM, increasing to 35.4kW if exhaust tuning can be permitted. The gasoline performance of this novel engine design is presented together with work to investigate the feasibility and performance characteristics of kerosene fuelling.
