Abstract

This paper describes the aerodynamic modelling of a generic Short Take-off and Vertical Landing (STOVL) aircraft to predict the forces and moments acting on the aircraft during shipborne operations. The study was conducted to investigate the impact on simulation fidelity of different methods of integrating ship airwake models with fixed-wing aircraft flight mechanics models. The paper describes the method used to compute the aerodynamic forces and moments acting on the aircraft when operating in the lee of the ship’s superstructure, and compares the aerodynamic effect on the aircraft at two wind conditions during hover over the ship’s flight deck. The STOVL aircraft’s forces and moments have been modelled at discrete sections over each lifting surface and integrated using strip theory. The underlying aerodynamic characteristics of each section were produced using a Vortex Lattice Method for NASA’s advanced STOVL concept aircraft. The time-varying components of velocity of the air flow produced by the ship’s superstructure at various conditions were then integrated into the model generating unsteady forces and moments on the aircraft.
