A test method for connector drop-off of space vehicle

Abstract

The invention provides a test method and a server for the drop-off of a connector of an aerospace vehicle. The method includes the following steps: collecting data parameters during the launching process of the first aerospace vehicle, calculating the acceleration of the space vehicle when the connector falls off during the launching process through the collected data, and obtaining the connector according to the acceleration and the collected data. Break away from the vector force of the vehicle and the force direction of the vector force, connect the space vehicle to be tested with the same specification to the connector, and apply the vector force to the connector, observe whether the connector can fall off, and then complete the test. The connector drop-off test method of the present invention can simulate the state of the connector falling off when the space vehicle is launched during the connector drop-off test process of the space vehicle to be tested, so as to realize a standardized drop-off test for the connector before the space vehicle launch , to make the test results more accurate, so as to achieve the purpose of connector drop-off test and improve the success rate of space vehicle launch.

Description

technical field [0001] The invention relates to the technical field of launch of space vehicles, in particular to a method for testing the disconnection of connectors of space vehicles. Background technique [0002] Usually, the liquid-carrying aerospace vehicle needs to be connected and refueled through the connector before take-off, and the connector needs to be separated from the vehicle after the refilling is completed. In some existing types of space vehicles, the disconnection of the connector is achieved by relying on external force to separate the plug before and after the space vehicle is ignited. Although there are very few aerospace companies that conduct drop-off tests before launch of space vehicles, the test methods are very irregular. [0003] The current test method only applies external force to pull the connector to make it fall off, which is regarded as the completion of the drop-off test. This method results in inconsistent force direction and force inte...

In some existing types of space vehicles, the disconnection of the connector is achieved by relying on external force to separate the plug before and after the space vehicle is ignited. The connector drop-off test, although there are very few aerospace companies will carry out the drop-off test before the launch of the space vehicle, but the test method is very irregular

[0003] The current test method only applies external force to pull the connector to make it fall off, which is regarded as the completion of the drop-off test. This method results in inconsistent force direction and force intensity for the umbilical cord connector to fall off during the drop-off test and when the space vehicle is launched. Therefore, the final test result is inaccurate, and cannot achieve the purpose of verifying whether the connector can fall off normally when the space vehicle is launched.
