Under a previous NASA contract and reported in CR-114289 methods for predicting the performance, noise, weight, and cost of propellers for advanced general aviation aircraft of the 1980 time period were developed and computerized. Under the presant contract this basic program was refined to incorporate a method of including the blade shape parameter, intagrated design lift coefficicent. This method and a reverse thrust computational procedure were included in the computer program, Ths weighkt equation was refined and also incorporated in the computer program. A User's Manual which includes a complete listing of this computer program with detailed instructions on its use has been written and will be published as a NASA low number Contractor Report.
