Bereits durchgefuhrte Untersuchungen auf der Leeseite eines angestellten Deltaflugels (im Anstellwinkelbereich von 5° bis 25°) haben demonstriert, dass die Dicke der Olschicht aus einer Sequenz von Olfilminterferenzbildern ausreichend genau bestimm

A study of the aerodynamic characteristics of two missile configurations has been performed using the data of an experiment, of a semi-empirical aerodynamic prediction code (Missile Datcom) and a RANS flow solver (TAU). The aerodynamic coefficients f

In this paper a self-aligning aerodisk to reduce the wave drag on a pitching missile is numerically investigated. The motion and the Mach number were chosen to match a maneuver flight of an actual missile: pitching frequency $f=7.5~Hz$, Mach number $

This numerical study is about the alleviation of the Phantom Yaw Effect on a pitching missile. A pair of slit shaped side jets, so called aerostrakes is used to force a symmetric separation at the shoulder of the missile. The unsteady Reynolds averag

The effect of a self-aligning aerodisk on the wave drag of a blunt slender body in a pitching maneuver has been numerically investigated. The self-alignment was realized by a coupling of the flow solver and a flight mechanics tool. The slender body w

The aerodynamics of a pitching slender body at $M=0.8$ with two different pivot locations have been numerically investigated using URANS with a two equation turbulence model. Identical to an experiment a sinusoidal motion between $\alpha=0^\circ$ and

This work describes experimental results of a wave drag reducing device tested in the Transonic Wind Tunnel in Gottingen both under static and dynamic conditions. By means of a self-aligning aerospike, the total drag of a blunt-nosed slender body has
