Numerical Simulation of Fully Coupled Flow-Field and Operational Limitation Envelopes of Helicopter-Ship Combinations

Landing a helicopter to the ship flight deck is most demanding even for experienced pilots and modeling simulation of ship-helicopter dynamic interface substantially challenging technical problem. In this paper, coupling numerical method was developed simulate fully coupled flow-field under complete wind-over-deck conditions. The steady actuator disk model based on momentum source approach resolved blade moving overset mesh were employed rotor. Two different combinations studied. mechanics established then influences airwake analyzed. Finally, derived rejection criterion safe landing method, envelopes these two predicted. found be effective in study operations shipboard environment. calculated indicate that an appropriate wind direction angle beneficial increasing allowable maximum speed operating boundary affected by rotation main
