Embodiment Construction

[0048] The invention relates to a test system for a thermal test run of an engine equipped with a gas rudder, which includes a mounting bracket and a force measuring device. The mounting bracket is connected with the end frame of the tail skirt of the engine, and is used to fix the force measuring device. It has the function of adjusting the axial and radial distance between the engine and the force measuring device, and realizes the positioning of the gas rudder relative to the engine nozzle, so that the flow of the gas rudder is The field is basically the same as that of the missile, and the force measuring device is suitable for engines of various sizes within a certain range. Multiple sets (usually four sets) of force measuring devices are installed on the installation end frame of the mounting bracket, and each set of force measuring devices is used to control the deflection of a piece of gas rudder in the jet flow of the engine according to the set requirements, and measure...

Abstract

The invention relates to a test system of gas vane carried engine hot commissioning. The test system of gas vane carried engine hot commissioning comprises force measurement devices and a mounting bracket, wherein the mounting bracket is connected with a tail skirt end frame of an engine, and the force measurement devices are connected with the mounting bracket; and the number of the force measurement devices is the same as that of gas vanes, and the force measurement devices are used for fixing and driving the gas vanes to quickly and accurately deviate in a tail jet flow of the engine, and measuring the actual deviation angle and corresponding pneumatic load of the gas vanes. The test system provided by the invention can simultaneously drive one or a plurality of gas vanes to quickly and accurately deviate in the jet flow of the engine and measure the pneumatic load and the actual deviation angle of the gas vanes in real time, and has the advantages of accurate simulation, high measurement precision, stronger generality and repeated use.

Description

technical field [0001] The invention relates to a test system for a thermal test run of an engine equipped with a gas rudder, belonging to the field of aerodynamic tests. Background technique [0002] With the development of thrust vectoring technology, gas rudders are used more and more as the actuators of missile thrust vector control. Due to the special characteristics of high temperature, strong corrosion and high scour, the jet flow of the engine is an unsteady jet flow, and it is difficult to obtain the real force of the gas rudder when it is working, whether it is theoretical calculation or wind tunnel test. The gas rudder is equipped with an engine hot test test to measure the force of the gas rudder under actual ablation conditions. The measurement results reflect the force of the gas rudder during the actual working process, which is the final data of the force of the gas rudder and the evaluation of the aerodynamic force of the gas rudder. The ultimate standard f...
