Quad Tiltrotor Aerodynamics in Ground Effect

Performance of a simplified Quad Tiltrotor (QTR) is studied in ground effect using CFD. The rotor systems are modeled in a time averaged sense using source terms for the forces in the momentum equations. Viscous body conforming overset meshes are used to model all the solid surfaces of the vehicle. The background Cartesian grid is used to specify the far-field boundary conditions and transfer i...

A Practical Method for Investigation of Aerodynamic and Longitudinal Static Stability of Wing-in-Ground Effect

The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...
