False-colour,high-speed differential interferometry image of an arrow-shaped projectile flying supersonically at around Mach 3. The speed of sound,designated Mach 1,is 331 metres per second (m/s). The image was produced at the Franco-German Research Institute,Saint-Louis,France,an organisation which specialises in ballistics research. Imagery of this kind is used to evaluate the aeroballistic properties for new designs of shells & bullets. Stability in flight is particularly important,especially so at high speeds,where the wind speed's influence on the rocket's trajectory (flight curve) is increased | |
