    SA (UHA Black Hawk, YEHB SOTAS, EHA Quick Fix) Background The UHA was the first model of the long Black Hawk helicopter series that officially started on Decem when Sikorsky was selected by the U.S. Army to build a production version of its YUHA Utility Tactical Transport Aircraft System (UTTAS) prototype.   Evaluating ship superstructure aerodynamics for maritime helicopter operations through CFD and flight simulation - Volume Issue - J.S. Forrest, C.H. Kaaria, I. OwenCited by: 7.

    A flight control design methodology for alleviating pilot workload during helicopter shipboard operations was developed and tested in simulation. The methodology uses modern MIMO control theory to improve gust rejection properties when operating in a turbulent ship airwake. The spectral properties of the airwake are identified using simulations and incorporated into the . UHA Black Hawk math model. For each of the three motion tuning methods, adjustments were made to the gain and washout frequency of the high pass filter designed to attenuate the math model accelerations before commanding the simulation motion platform.
