The H-3 series helicopter program has been used to provide a basis for the trade-off studies. The test and service experience has been reviewed to provide a data bank on the performance of transmission and rotor system components and to determine modes and types of failures. The extent of correlation between failures during the initial test programs and those problem areas that were later detected during actual usage was investigated to determine the effectiveness of the test programs. Several changes have been advocated in both testing philosophy and the corresponding test techniques since the H-3 helicopter test program commenced. Various testing concepts have been considered and compared to develop a recommended test program for a single-rotor helicopter having a nominal gross weight of 15,000 pounds. (Author)
