Embodiment Construction
[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] Such as figure 1 As shown, the method of this embodiment is as follows.
[0030] Step 1: Divide the ejection seat ejection process into two stages, establish a mathematical model according to the specific conditions of each stage, and compile a computer simulation calculation program;
[0031] The first stage: the ejection seat is stuck in the guide rail groove by two pairs of pulleys, and the ejection seat system can only move along the direction of the guide rail and cannot rotate. At this time, the ejection seat system is affected by the thrust and gravity of the rocket package;
[0032] The second stage: the ejection seat only has a pair of pulleys in the ejec...
