Project 15: Advanced Multi-Aircraft Shipboard Landing Model

Summary of Services Performed: Model aerodynamic interaction of multiple aircraft in a shipboard environment

The goal of this SBIR was to develop physically based advanced aircraft/ship dynamic and aerodynamic interaction models to support multi-aircraft shipboard landing simulation. The work emphasized the development of critical modeling components for the multi-aircraft interaction including an advanced horseshoe vortex model for wing interference and an advanced finite state dynamic wake module and time-accurate distorted vortex model for rotor wake solution. To fully address the complicated multi-aircraft/ship interaction, efforts were also made toward a comprehensive integration of each modeling aspect including ship dynamics, ship airwake, high fidelity rotorcraft blade element model, accurate landing gear modeling, rotor wake/ship deck aerodynamic interaction, and rotor wake interference.

The development of multi-aircraft interference modeling and simulation will strongly benefit aircraft shipboard operations and support the process of design, training, and planning. It will also benefit commercial airlines for take-off and landing safety and improvement of terminal area operation efficiency. Advanced Rotorcraft Technology, Inc.

Title: Advanced Multi-Aircraft Shipboard Landing Model

Significant breakthroughs have been made through this SBIR in developing advanced rotor wake interference models in support of land-based and shipboard rotorcraft operations. Both a high order finite state dynamic wake interference model and a time-accurate distorted vortex interference model have been developed for multi-aircraft aerodynamic interaction simulation. To accurately predict complicated shipboard multi-aircraft interference, the effects of the unsteady ship airwake were also addressed. An efficient ship airwake model was developed which can be used as a practical tool for ship airwake and rotor downwash interaction study. The advanced rotor interference models developed can be applied for aircraft spacing and air traffic control analysis and simulation. Coupled with an unsteady ship airwake interference model, the rotor wake interference model can also provide a unified formulation for multiaircraft shipboard landing analysis and simulation.
