“…Therefore, the resulting WOD angle must align with a WOD angle from the original CFD datasets. The CFD airwake velocity components at each lookup point ( ⃗ ) are scaled based on the simulation WOD speed, and the perturbation velocities (∆ ⃗⃗⃗⃗⃗ ) are calculated using Equation 3.…”

“…The goal of JSHIP was to enable interoperability of shipboard operations for US Navy, Army and Air Force helicopters [Ref. [1][2][3][4]. A man-in-the-loop flight simulation was developed at the NASA Ames Vertical Motion Simulator (VMS), which replicated the dynamic interface environment for an LHA class ship and UH-60A Black Hawk helicopter.…”

Dynamic interface refers to shipboard aircraft launch and recovery operations including the testing required to determine flight envelope limits as a function of wind speed and direction. Ship-based flight operations must contend with challenges unique to the maritime environment such as ship motion and airwake turbulence created by the ship's superstructure. Ship airwake affects aircraft performance and handling qualities characteristics which in turn impact pilot workload. Ship airwake characteristics vary from ship to ship and also from one relative wind angle to the next for the same ship. The ability to assess ship airwake severity in a simulation environment allows airwake related design considerations, such as ship geometric layout and aircraft flight control design, to be addressed during the design process. NAVAIR has developed a desktop airwake analysis tool to model the handling characteristics of an aircraft when subjected to time accurate ship airwake velocities created with Computational Fluid Dynamics (CFD). The tool has been applied to multiple ship configurations to assess airwake impact on both rotary wing and fixed wing aircraft. This work describes the real-time aircraft flight dynamics models and CFD airwake models that make up the airwake evaluation tool, summarizes verification and validation efforts, and describes the comparative process used to evaluate ship airwake severity for an example ship configuration.

“…Landing a helicopter on a moving aircraft carrier is one of the most challenging tasks a helicopter pilot can face [4]. Because of the movement of the ship, its superstructure will always generate disturbed airflow such as vortices and turbulence.…”
