Abstract
The requirements imposed by EADS Deutschland GmbH for the design of a new
high velocity missile V/SHORADS (Very/Short Range Air Defence System) are
the reduction of drag and to obtain reliable information from the opto-electronic
embedded sensors at even high angles of attack. The aim of our investigation is
to find new spike geometries and to optimise these to reach high angles of attack
without losing the drag reduction effect well-known for small angles of attack.
Flow visualisation pictures taken with differential interferometry are shown. A
classical disk spike geometry is compared with a new spherical spike and the
advantages of
