Euler Solution for a Complete Fighter Aircraft at Sub- and Supersonic Speed,
Abstract
A survey is given on the construction of a novel high resolution Euler code which is applied for airflow calculations past a fighter type aircraft. The principle feature of the flow solver is a Godunov type averaging procedure based on the eigenvalue analysis of the Euler equations by means of which the fluxes are evaluated at the finite volume faces which separate constant sets of flow variables on either side. The procedure is third order accurate and locally monotonicity preserving thus avoiding the drawbacks of global TVD-schemes. The grid generation for complex configuration is performed from solutions of linear biharmonic equations with only one parameter prescribed by the program user. Vector computer performance of the explicit and implicit program versions are considered.
