Observations on the Design and Operation of Pulsejet Engines as Derived from an Experimental and Theoretical Investigation 840422

This paper describes some of the experimental and theoretical work carried out at the Queen's University, Belfast in connection with a pulsejet project. It starts from the earliest stages of trying to achieve a working reed valved engine and continues to the present where valve less pulsejets have been designed with the aid of a simulation program.
Suggestions are made regarding the manner in which various parameters such as duct and intake geometry, orientation and flight speed can affect performance. It suggests four main criteria which must be fulfilled for any valveless pulsejet to operate successfully and discusses methods by which these can be achieved.
