碩士 / 國防大學中正理工學院 / 兵器系統工程研究所 / 94 / In this thesis, the investigation of onboard helicopter flight safe operating envelopes in different kinds of sea conditions set by flying qualities during landing are of particular interest. This thesis includes five key steps: Firstly, incorporating the six degree-of-freedom equations of motion and the steady-state airwake on the flight deck, the helicopter/ship recovery model is established. Second, we analyse the influence of ship speed and wave cycle to the ship motions in different kinds of sea conditions. Third, three kinds of controller are designed by flight quality to simulate the driving technologies and experiences of the three levels of pilot. The Quickness Criteria flight qualities in ADS-33 are introduced to determine the closed loop poles. Fourth, we define the theoretical flight safe operating envelope of onboard helicopter and the simulation processes to determine the theoretical flight safe operating envelope for helicopter landing on a ship. Fifth, the differences of the theoretical flight safe operating envelopes in different kinds of sea conditions and controllers are studied. Finally, we use of Matlab in Virtual reality Toolbox to simulate the scene when a helicopter lands on a ship. This thesis is expected to be helpful to the pilot training, flight safety and analysis of the margin of the helicopter/ship flight safe operating envelope.
