| Popis: | An analysis of the shipboard characteristics of the SH-2F helicopter in response to prescribed deck motion, deck friction, and steady wind conditions has been developed. The objective of deriving the SH-2F shipboard dynamic model is to define safe conditions for launching and recovering the helicopter from the flight deck of U.S. Navy frigates and destroyers. Operational conditions of interest include helicopter and ship deck dynamic interactions that could potentially cause dangerous interference between the helicopter and the ship, such as sliding or tipping of the helicopter. The wind condition, ship deck motion, helicopter rotor thrust, and friction coefficients between helicopter tires and flight-deck surfaces are found to be important parameters that affect the helicopter shipboard operations. Four sets of aerodynamic characteristics are modeled in the analysis: one with the rotor operating; one with the rotor stopped and inoperative; one with rotor folded; and one for the fuselage. The ship motion data, including three linear translation and two angular rotation degrees of freedom (roll and pitch) are described in the time domain. The equations of motion of the shipboard dynamic model are derived using the energy method. |
