Complex Numerical Modeling of Dynamics and Crashes of Wing-in-Ground Vehicles

Abstract

The Wing-In-Ground craft (WIG), a vehicle flying in
\nthe ground effect, is a promising transportation means
\nof the near future. This paper describes mathematical
\nmodeling of WIG motion in all regimes, such as
\nplaning, take-off, transition to flight, and flight itself.
\nThe model, which includes nonlinear hydroaerodynamics,
\nserves as a base for simulation of
\nmotion. The theory developed here enhances the
\nprocess of designing WIG vehicles; its advantages and
\ndisadvantages are discussed. The results of numerical
\nmodeling are compared with experimental data
\nobtained for planing and flight regimes of motion. The
\nmodel is applied for studying emergency problems in
\nWIG operation.
