Abstract:

Four crane-type tandem-rotor helicopters with the gross weight capability of 50,000 lb, 80,000 lb, 120,000 lb, and 200,000 lb are defined in terms of rotor and fuselage parameters and the resulting dynamic characteristics. An automatic precision hover system PHS is synthesized and the hover hold system performance is established analytically including aircraft position errors and pilot station acceleration environment as a function of low speed turbulence. In addition, pilot modeling techniques are utilized to estimate the performance and rating for various attitude and linear velocity control response modes without the aid of automatic hold functions.
