Problems solved by technology

This type of nozzle usually does not have the feature of automatically rebounding to zero and maintaining it. Therefore, the nozzle will fall to the swing limit position due to its own gravity when the rocket is in a horizontal state, causing damage to the product structure

Abstract

The invention provides a level test method for an electromechanical servo mechanism of a carrier rocket. The method comprises the steps: S1, enabling a tester connected to the electromechanical servo mechanism to be powered on, reading a first angle position of a current spray pipe through the tester, and transmitting a control instruction of the first angle position to the electromechanical servo mechanism; S2, enabling the electromechanical servo mechanism to provide power according to the control instruction so that the spray pipe can be kept at the first angle position; S3, dismantling the supporting tool from the position below the spray pipe; S4, enabling the tester to send a control instruction of a zero angle position to the electromechanical servo mechanism, and carrying out a test item of the electromechanical servo mechanism after the spray pipe reaches the zero angle position; S5, after the test item is finished, enabling the tester to sends the control instruction of a zero angle position to the electromechanical servo mechanism, and after the spray pipe reaches the zero angle position, installing the supporting tool below the spray pipe; and S6, cutting off the power supply of the tester. The testing method can ensure that the engine spray pipe is safe and reliable in the testing process.

Description

technical field [0001] The invention relates to the field of launch vehicle engine testing, in particular to a test method for the level of a launch vehicle electromechanical servo mechanism and a computer storage medium. Background technique [0002] The servo mechanism is an important device for the swing of the rocket engine nozzle. The servo mechanism drives the engine to swing to realize the thrust vector control function of the rocket attitude control system. In each test stage of the rocket after the servo mechanism is loaded with arrows, the servo mechanism needs to be tested. [0003] Most traditional launch vehicles use hydraulic or electro-hydraulic servo mechanisms. In recent years, with the gradual improvement of the performance of the electromechanical servo mechanism, the electromechanical servo mechanism has gradually begun to be applied to the launch vehicle. [0004] As the capacity of the launch vehicle continues to increase, the weight of the correspond...
