Abstract
The invention relates to an attitude adjusting device, in particular to an automatic engine attitude adjusting device, and solves the problems of high cost and long test period due to the fact that different attack angle brackets are adopted to adjust different attack angles when an existing rocket engine is subjected to a wind tunnel test. The Y-direction lifting platform moves in the vertical direction through the Y-direction hydraulic cylinder, and the X-direction moving platform is driven by the X-direction hydraulic cylinder to move in the horizontal direction. The angle changing platform can rotate around a hinged shaft of the angle changing platform and the X-direction moving platform through angle adjusting hydraulic cylinders arranged at the two ends of the X-direction moving platform respectively, attack angle changing is achieved, and the expansion amount of the Y-direction hydraulic cylinder, the X-direction hydraulic cylinder and the angle adjusting hydraulic cylinders is controlled through an upper computer. And displacement sensors arranged in the three are used for monitoring the expansion and contraction amount and angle sensors are used for monitoring the pitching angle, so that the real-time adjustment of different attack angles and the front-back and high-low positions of the engine is completed.
