The nose portion of a missile having a ram air turbine for driving an electric generator for supplying electric power to the electric circuits of the missile, especially of its fuse, is designed in a special manner in order to provide, at high missile speeds, a throttling of the air flow, whereby the speed of rotation of the turbine may be kept within reasonable limits. Thus, the air inlet is divided in a plurality of inlet ducts arranged as a wreath around the foward end of the missile. Further, the outlet openings are forwardly directed and co-operate with the shock waves from the acute forward end of the missile and from an annular edge surrounding the wreath of inlets but lying radially inside the outlet openings. |
