A nonlinear stochastic dynamic model is established which takes into consideration aircraft body pitch movements and the elastic vibration excited by the random runway.

To acquire projectile body pitch and roll parameters on real-time, put forward a new projectile body attitude method, using to obtain geomagnetic field intensity and combine microcomputer gyroscope.

Indeed the rich men who held his contracts insisted he take the drugs, because their bank balances needed him on the pitch, regardless of the damage which cortisone can do to the body in later life.
