Embodiment Construction

[0014] The present invention will hereinafter be described in more detail with reference to the accompanying drawings, which illustrate embodiments of the invention. However, the present invention may be embodied in many different forms and should not be construed as limited by the embodiments set forth herein.

[0015] The quick-assembled oblique nozzle solid rocket motor test frame of the embodiment of the present invention is mainly composed of two parts: a fixed frame and a movable frame. figure 1 Shown is the structure diagram of the inclined nozzle solid rocket motor test frame of the preferred embodiment, including a top plate 1, a column 2, an upper support roller 3, a sliding platform 4, a lower support roller 5, a base 6, and a thrust bracket 7; wherein, the fixed frame It is mainly composed of top plate 1, upright column 2, upper support roller 3, lower support roller 5 and base 6. In this example, the fixed frame body composed of the top plate 1 , the upright colu...

Abstract

The invention discloses an inclined-jet-pipe solid rocket engine test rack of a quick assembly type. A moving rack and a fixed rack cooperate with each other through a V-shaped limiting mechanism, thereby achieving the limiting in other directions while guaranteeing the freedom degree of a main pushing force testing direction of an engine. Two ends of the moving rack are of a V-shaped inclined port design, thereby guaranteeing that the surface is smooth enough. A fixed rack vertical column is provided with upper and lower supporting rollers, and the surfaces of the upper and lower supporting rollers are distributed in a V shape, and cooperate with a V-shaped inclined port of the moving rack for installation. The upper end face of the moving rack can be provided with a fixed test engine, thereby guaranteeing that the axis of an inclined jet pipe of the test engine is parallel to the surface of a platform, and is located in a central tangent plane of the moving rack. A pushing force support is disposed at the center of the front end face of the moving face, and can guarantee that the main pushing force axis of the test engine is coincided with the axis of a bearing force point of a pushing force support. A static frame bottom plate is provided with a positioning boss which cooperates with a ground static test bench body.

Description

technical field [0001] The technology of the invention relates to the field of mechanical design, in particular to a fast-assembled oblique nozzle solid rocket motor test stand, which is mainly used for the main thrust test in the ground static test of the oblique nozzle solid rocket motor. Background technique [0002] The solid rocket motor test stand is an indispensable test device in the ground static test. When in use, the engine is fixed on the test frame, and whether the test frame can accurately transmit the thrust to the sensor will directly affect the thrust test accuracy. The nozzle axis of a conventional solid rocket motor coincides with the axis of the combustion chamber, and the main thrust generated during operation is consistent with the axis of the combustion chamber shell. The roller structure test stand used in the early stage of development can complete the main thrust test of the test engine by arranging and installing the test engine along the axial di...
