Propulsion and Power Supplies for Unmanned Vehicles. Volume I. Engines for Small Propeller-Driven RPVS
Abstract
In this report engines in the power range up to 100 hp are studied for application into small propeller-driven RPVs. From an inventory of existing engines, it is found that a number of two-and four-stroke piston engines in this power class are available, but most of them will not fulfill the requirements for RPV-applications with respect to reliability, quality control, noise vibrations, etc. Up till now no other types of shaft-power engines are available for application to small RPVs although turboshaft engines and possibly also electrically-driven propellers might offer advantages for some missions. For payloads between 10 and 50 kg and flight endurances of up to 3 hours some parametric calculations are presented for fixed-wing rotary-wing vehicles, to illustrate vehicle sizes and engine power requirements. Some recommendations are given for the future development of piston-and turbo-shaft engines suitable for propeller-driven RPVs, emphasizing the need for Demonstrator Engine Programs. Data on actual and projected engines and some typical specifications are added in appendici. (Author)
