Experimental Investigation of Hydrocarbon Based Fuels in Solid Fuel Ramjet Propulsion

摘要

Solid-fuel ramjet is a reliable and competitive air breathing propulsion system for modern tactile missiles. Solid-fuel performance characteristics applied to such systems, in different motor configurations, have been under investigation for decades. More recently a myriad of hydrocarbon base materials is being investigated for hybrid propellant rocket engines. Most of them could be applied in solid fuel ramjet engines (SFRJ), such as paraffin, vegetal waxes and more traditional hydrocarbons base materials with additives. In this paper we present a novel SFRJ test bench and associate methodology suitable for testing fuels burning with high temperature air stream, typical of flying regimes of tactical missiles.
