Modelowanie matematyczne sterowanego ruchu samolotu w korkociągu

Wojciech Blajer, Jerzy Maryniak

For a rigid plane, a mathematical model for computer digital simulation of airplane motion in spin is presented. Deflections of control surfaces have been assumed to have an influence only on aerodynamic forces and moments acting on the plane in flight. The model have considered aircraft controlling by changes of ailerons, horizontal and vertical tails, jet thrust and angular velocity of jet rotation. Accordingly to a programmed flight mode, reactions of the pilot controlling an aircraft in spin have been modelled. Test results of digital computer simulation carried out for TS-11 ``Iskra'' aircraft motion in spin entry, developed spin and spin departure are presented.
