About the course

Within the framework of this course, the participants will gain fundamental knowledge in the field of rocket technology and jet propulsion theory. The basis of the course is the generally accepted scheme of dividing the rocket flight path into sections and the control program for each of them.

In the process of instruction the course participants are to learn about the rocket flight conditions at all stages of its motion (from launch to the moment of reaching the target orbit), as well as the forces and moments acting on the rocket in flight and mathematical models they are described by. Special attention in the course is paid to the choice of rocket design characteristics, ensuring the implementation of the target task.

After theoretical training, the participants will be asked to select the launch vehicle from the available prototypes, to specify its design parameters for solving the problem of rocket injection into the target orbit and to calculate the basic flight characteristics of the launch vehicle, including the control program for individual stages.
