Modeling the dynamics of an aircraft ejection seat

The article presents the dynamics of the SK ejection seat of the TS-11 “Iskra” jet trainer-fighter aircraft. The ejection seat and its operating principle are characterized. A mathematical and computer model of the object was developed using the MATLAB-Simulink program, and a simulation was conducted for various flight speeds.1. INTRODUCTION
The first ejection seats were used in Heinkel “He-162 Salamander” aircraft in 1939. Some ejections ended in failure at that time due to a collision between the seat-pilot system and the aircraft. Since then, rescue systems have been constantly improved. According to [2], ejection seats can be divided into 4 generations:
I. First – developed in the years 1940-1965. It used compressed air, a rocket motor, or a pyrotechnic cartridge. The task of this type of seat was to eject the pilot outside the aircraft. In the first versions, the pilot manually opened the parachute.
II. Second – years 1965 – 1975. The rocket motor was improved, reducing the probability of injury. The latest versions of ejection seats of this generation allow for operation at an altitude of 0m at a speed of 0km/h (0-0 class). (…)
