Modelling of the ejection process in a symmetrical flight

Głowiński S., Krzyżyński T.

Journal of Theoretical and Applied Mechanics

2013

Vol. 51 nr 3

775--785

This paper presents a mathematical model of the ejection seat trajectory in a symmetrical design. The component speeds and displacements of the seat in function of time are determined by means of an analytical method. The model takes into account the change of air density in function of height and the change of free fall acceleration dependent on the latitude and flight height of the seat. The gravity load that acts on the pilot in the chest-back direction in function of the flight height and speed is determined. The mathematical model with the initial conditions is used for creation of a computer application with the use of MATLAB software, owing to which it was possible to obtain the flight trajectory of the seat in relation to the aircraft and in relation to the ground. The minimum distance which the seat flows over the vertical stabilizer depending from the pilot’s mass and the aircraft speed is determined.

Simulation of trajectory of an aircraft seat ejection

Głowiński S., Krzyżyński T.

Symulacja w Badaniach i Rozwoju

2010

Vol. 1, nr 4

343-351

The paper deals with modeling and simulation of motion trajectory of an ejection seat in the training-combat aircraft TS-11 "Iskra". The ejection seat and its operation are characterized. Mathematical and computer models are elaborated with the help of MATLAB-Simulink applications. Additionally, simulations are conducted for various velocities of the aircraft.

W artykule przedstawiono dynamikę fotela katapultowego o nazwie SK na podstawie odrzutowego szkolno-bojowego samolotu TS-11 "Iskra". Scharakteryzowano fotel katapultowy i zasadę jego działania. Opracowano model matematyczny oraz komputerowy obiektu przy wykorzystaniu programu MATLAB – Simulink i przeprowadzono symulację przy różnych prędkościach lotu.
