Research Institution
"Safe and effective shipboard aircraft operation is a challenging task for both pilot and ship deck operators. The launch and recovery of manned and autonomous aircraft are strongly affected by ship motion in the ocean wind and wave environment, the shipinduced air wake, and aircraft interaction with the ship dynamics and the ship air wake. A simulation tool is needed to model pilot/aircraft/ship/air wake interaction for purpose of design, operational analysis, and training. We propose to1. Perform a comprehensive parametric study to investigate the effects of important ship air wake and turbulence parameters (e.g., intensity, spatial grid and time scale, etc.) on the aircraft response. The study will identify the essential characteristicsof the ship air wake for accurate simulation of shipboard aircraft launch and recovery operations.2. Develop an interface between the ship dynamics and ship air wake models to address the effect of ship dynamic motion (e.g., pitch and roll) in addition to the current wind over deck speed and angle variation.3. Develop an intelligent pilot interface model to address the pilot/aircraft interaction to simulate Mission Task Elements of shipboard aircraft launch and recovery. The tool developed will benefit military autonomous and manned rotary wing or fixed wing aircraft launch and recovery from ship and support the process of design, training, and planning. It will also benefit commercial airlines
