    A VALIDATION OF THE JOINT ARMY/NAVY ROTORCRAFT ANALYSIS AND DESIGN SOFTWARE BY COMPARISON WITH H AND UHA FLIGHT TEST David M. Eccles Lieutenant, United States Navy B.S.E.E., Tufts University, Submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AERONAUTICAL ENGINEERING from the Author: Approved by. In analyzing the influence of the helicopter control response of collective pitch, the UHA helicopter is still used with a forward flight speed of V = km/h. According to the flight condition of the flight-test, the collective pitch control input by the driver is cm upward and the process of control is shown in Fig. by: 4.

    A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. UHA Black Hawk helicopter, for which flight test data is available in public domain. The control prediction capabil-ity of the present analysis is then verified for other maneuve rs such as pop-up and hurdle-hop maneuvers for Westland Lynx helicopter with available simulated results from literature.

    Main Rotor Model. The main rotor of UH helicopter is a single rotor type and can be modelled throughout blade element theory. The relative lift and drag coefficients for blade segments are provided with verified wind tunnel test data [19, 20].Through this model, the flapping and lag dynamics, which are the main motions of the main rotor, can be simulated by: 4.
