SUMMARY
A major outcome of the studies sponsored by the Advanced Concept and Mission
Division, A. C. M. D. of NASA under Contract No. NAS2-5885 dated 30 January 1970
as reported in CR 114289 and under Contract No. NAS2-6477 dated 6 May 1971 as
reported in CR 114399 has been the development of a computer program for eval-
uating propeller performance (static, flight, reverse), noise, weight, and cost for
general aviation aircraft propellers as a function of the prime geometric and aero-
dynamic variables. Propellers have been divided into five classifications which
distinguish the complexity of general aviation propellers, i. e. , fixed versus variable
pitch, deicing capability, full feathering capability, and reverse thrust capability.
Parameters that may be varied independently include number of blades, blade activity
factor, blade integrated design lift coefficient, and blade tipspeed. A User's Manual
for the computer program was written under Contract No. NAS2-6477 and is presented
herein.
A brief description of the technology development is presented, and a complete
listing of the computer program as well as detailed instructions and samples of input
and output are included. Examples of parametric studies which can be made with the
computer program are shown.
