False-colour,high-speed image showing the air flow around a 20mm calibre bullet flying at 500 metres per second (m/s). The projectile's flight was recorded by differential interferometry,using polarised light with the aid of a pulsed YAG laser,in an exposure time of 20 nanoseconds (ns). 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 of new designs of shells & bullets | |
