Abstract

The invention belongs to the technical field of aerospace testing, provides a scramjet engine fuel gas analysis high-enthalpy sampling probe, and particularly provides a blow-down scramjet engine combustion device and a fuel gas sampling probe for capturing high-enthalpy fuel gas in engine combustor tests.

Description

Technical field [0001] The invention belongs to the technical field of aerospace testing, and provides a high enthalpy sampling probe for gas analysis of scramjets, and in particular provides a method for capturing reality in the test of temporary impulse scramjet burners and engine combustion chambers. Gas sampling probe for high enthalpy gas. Background technique [0002] In the process of developing hypersonic propulsion, scramjet has always been a focus of attention. When evaluating the comprehensive performance of the scramjet combustion chamber, it is difficult to directly determine the comprehensive performance due to the high temperature in the combustion chamber, the fast gas velocity, and the influence of the complex shock wave system in the combustion chamber. At present, among the existing multiple combustion chamber performance evaluation methods, the sampling method has attracted attention because of its multi-point measurement, simple structure, easy-to-find mater...
