Paper Abstract

The orthogonal photography aims at the restitution in the tridimensional space of the position and the attitude of a physical object. In our particular application of the orthogonal photo-graphy, the object is a small caliber projectile in flight and each station realises the orthogonal shadowphotography of the projectile in true size. Using several mutually aligned stations along the trajectory, the position of the center of gravity as well as the attitude in space of the projectile can be restituted. Using this information the spatial angle of attack and its rate of variation can be deduced. In comparison with the photography based on reflexion, the shadowphotography has the advantage that some characteristics of the supersonic flow around the projectile are visualised.
