A two-dimensional transparent thrust chamber, approximat ing a slice, 0.47 in . thick from a 1000-lb thrust c h a m ber, was used for tests of five different injector types. Motion pictures at 2000 and 3000 frames per second were taken of the combust ion process. The different combust ion patterns and some examples of combust ion instabil ity are i l lustrated. Curves are shown for chamber gas velocities versus axial distances from the injector faces, and the velocities obtained wi th each injector type are compared.
