Procedural aspects of testing aerodynamic models with combustion in high-enthalpy transient-mode installations

Feed, wind-tunnel balance, pressure, and heat flow instrumentation systems are developed for short-term testing of various models with combustion for different relative positions of the nozzle, the models and the systems that support the models and instrumentation complex. The models are tested in an IT-301 pulsed wind tunnel with various media being input to the model. The models examined are a flat plat for studying spontaneous ignition of fuel media, or gasdynamic models for investigating the gas dynamics of suppling heat to the channel of the model. A feed system based on the electrohydraulic effect is developed. The methods used to study the force characteristics and pressure in the models are described.
