Project SQUID - A program of Fundamental Research on Liquid Rocket and Pulse Jet Propulsion

Abstract

The progress made in fundamental research on liquid rocket and pulsejet engines is discussed. Experimental work on flame propagation in tubes continued with the application of more accurate techniques. A schlieren technique was used for recording phenomena at the lip of the flame tube. Schlieren motion pictures of the flow at the exhaust end of a pulsejet in operation have been made and led to a semi-quantitative description of the flow and jet action. Results of the numerical evaluation of special and complete solution of the differential equations representing the air inflow between moving reed valves show that under properly chosen conditions of design the reed valves move during the opening period without oscillation and that a smooth nozzle flow for the air can be achieved. A theoretical investigation of the laminar boundary layer flowing along a porous flat plate with fluid injected through the porous cells of the plate is presented.
