The book highlights one of the most complex sections of aircraft flight dynamics - corkscrew dynamics. Conditions and peculiarities of the aircraft getting into the corkscrew are considered. Classification, analysis of peculiarities and methods of corkscrew study of modern aircrafts are presented, analytical methods of calculation of parameters of aircraft trajectories in corkscrew, results of simulation and flight tests of aircrafts for corkscrew are presented. Description of aircraft movement mechanics at high angles-of-attack and. piloting methods, which provide flight safety in the modes under consideration.
