Experimental Study of Thrust Characteristics of a Model Air-Breathing Ejector-Type Combustor with Vibrational Burning of Hydrogen

摘要

The dependence of thrust of an air-breathing ejector-type combustor on its geometric parameters are experimentally determined in the case of vibrational burning of hydrogen in the combustor.The combustor is a cylindrical tube with a confuser at the entrance and a diffuser at the exit.It is shown that there is a certain limiting size of the confuser and a certain limiting length of the combustor,which ensure the maximum thrust.
