Abstract
Background. As is known, the rocket must have sufficient strength and withstand all loads during operation. The test of the design of the rocket for strength can be carried out in two ways: on workloads or by calculated loads exceeding workers. When studying the loads acting on the rocket, special attention should be paid to flight loads. Load in flight depends on the characteristics of the rocket engine, the nature of the air flow rocket and the dynamics of the movement. Materials and methods. The calculation is made at maximum high-speed pressure in the exit zone of two-stage liquid fuels into the rocket housing. We can say that the head of the rocket is made in the form of a sharp cone Results. As a result of research, it is possible to note the fact that in training with reinforcement an agent interacts with the environment, taking actions and receives a reward for these actions. Conclusions. With any calculation of testing tests, errors will be selected when choosing a design selection circuit. To test the results of the calculation, it is sufficient to test the structure before it is destruction, with a uniform increase in the load.
