Title The burning rate of erosion test system design
Abstract
This paper introduces a kind of displacement measurement system based on solid-state image sensor displacement measurement system of solid rocket propellant erosive burning rate measurement method.The test propellant specimens were fixed in the transparent window engine system(by the gas generator,the transparent window to the test section,the nozzle is composed of three parts).When the engine ignition, high temperature and high speed airflow generated by the gas generator into the test section will lit propellant samples.Flame retardant coated propellant samples in advance,leaving only one side in contact with the high temperature gas,so that the specimen along the surface normal direction of combustion.Through the transparent window and the optical system,the signal of propellant combustion (only light the gas channel)collect to the solid-state image sensor,solid-state image sensor convert it to electrical signal and output.The output signal after filtering,A/D conversion input into the computer for processing,and then get the propellant burning rate with time and pressure curve and the erosion function.
Keywords the solid-state image sensor displacement measurement solid rocket propellant erosive burning rate transparent window engine system
