A nonlinear generic helicopter model based on the following NASA AMES reports:

NASA TM-84281 'A Mathematical Model of a Single Main Rotor Helicopter for Piloted Simulation', P.D.Talbot, B.E.Tinling, W.A.Decker, R.T.N.Chen
NASA TM-85890 'A Mathematical Model of the UH-60 Helicopter', K.B.Hilbert

To run the nonlinear simulation model:
1. Open 'initialize.m', set trim speed 'v_kts' as: 1, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110,120, 130 or 140
2. Open simulink model 'helo.xls'
3. Run model
