Embodiment Construction

[0026] Specific implementation

[0027] The present invention will be further explained below in conjunction with the drawings and embodiments:

[0028] The entire high overload test system consists of two parts: mechanical system and electrical system. The rotating test bench is the main body of the mechanical system of the high-overload test device, which is used to provide the necessary rotating conditions for the test and to withstand the load generated when the engine is working. Such as figure 1 As shown, the rotating test bench adopts a vertical structure, and includes a rotating table 1, a bearing shaft assembly 2, a bearing assembly 3, a frame 4, a transmission shaft assembly 5, and a slip ring assembly 6. Its working principle is: the motor is connected with the drive shaft assembly 5 through a coupling to provide the power required for rotation of the rotating test bench; the load of the rotating test bench is mainly borne by the bearing shaft assembly 2; the bearing sh...

Abstract

The invention discloses an ignition driving system of a high-overload test device used for a solid-propellant rocket engine, relates to an ignition driving system used for a solid-propellant rocket engine experimental apparatus and in particular to an ignition driving system used for a solid-propellant rocket engine under the high-overload rotation test condition, and belongs to the field of aerospace. The ignition driving system comprises a long-distance integrated console, an ignition power supply control module, a test controller, a relay driving module, a solid-propellant rocket engine and an ignition tool, wherein the relay driving module is fixed on a noseplate on the central axis plane of a rotary test bench, and the axial line between the relay moving contact C and the relay stationary contact D in the relay driving module is tangent to a rotary table top. The ignition driving system can reduce or eliminate the adverse effect of radial centrifugal inertia and tangential acceleration impact on the relay driving module in the ignition power supply loop under the high-overload test condition. The ignition driving system has high dynamic operating precision and can be used for reliably and safely carrying out a continuous ignition test on solid-propellant rocket engines under high-overload rotary conditions.

Description

Technical field [0001] The invention relates to an ignition driving system for a solid rocket motor experimental device, in particular to an ignition driving system for a solid rocket motor under high overload rotation test conditions, and belongs to the field of aerospace. Background technique [0002] The high maneuverability and high-speed rotation during the flight of modern missiles will cause the solid rocket motor on it to bear high overload, which puts forward corresponding requirements for the design and development of solid rocket motors. On the one hand, overload acceleration will increase the burning rate of the propellant, induce the increase in combustion chamber pressure and shorten the combustion time, and ultimately lead to changes in the internal ballistic performance of the engine; on the other hand, high overload will seriously affect the movement of condensed particles. Deteriorating the working environment of the engine's thermal insulation layer, in severe ...
