The Missile Internal Power (MIP) project has studied the problem of developing integrated power supplies of minimum weight capable of providing regulated electrical power in an isolated environment subject to severe climatic and force conditions. An initial study of alternative energy sources and components revealed the most promising system. Basic investigations of the properties and characteristics of solid fuels and of design criteria for partial admission turbines and electrical machinery were conducted, as was the study of several competitive regulation schemes. Based on the results of the basic investigations, and adhering faithfully to the requirements imposed by the environment and the specifications of the missile system, two electrical power units (EPU's) were developed and tested at the Dynamic Analysis and Control Laboratory (D. A. C. L. ). Both units were subsequently exhaustively and successfully tested in the respective missiles and both units have proven successful in missile test flight. Extending the foregoing program, a study of optimum electrical voltage and frequency standards for missile systems has been made and recommendations which could materially reduce system weight have been advanced.
