High Incidence Buffet Flow over Fighter Type Aircraftthe full angle of attack range up to α = 90 °. The RMS-values of the fin surface pressure fluctuations and related power spectral densities are presented and used to discuss the influence of various flow features. A known relation based on wing sweep angle and angle of attack for the dominant freque

Flap efficiency of a delta wing with an external store using an Euler code for small disturbances an outboard flap. The store is attached to the wing on the lower surface in the area of the outboard flap. For this geometry a structured multiblock mesh has been generated and elliptically smoothed. Numerical investigations are carried out with an Euler code using a small disturbance solver (FLM-S

Experimental investigation of local vortex roughness receptivity of a boundary layer on an airfoilhe convected wake of a vibrating wire that is oriented perpendicular to the free stream speed vector and parallel to the airfoil surface. Hot-wire measurements were taken down­stream of local 2D and 3D roughness elements, phase-locked with the wire vibra­tions to study the Tollmien-Schlichting (TS)

The first summit meeting of President Reagan and General Secretary Gorbachev in Geneva just a few weeks earlier had resolved none of the much-pub
