Abstract : The report portrays an analysis method which was developed for determining the weight, size, and performance of helicopters. The analysis method was programmed in FORTRAN IV for use on a high speed digital computer (BRLESC). The program was specifically developed for trending and comparison purposes. There are sixteen helicopter characteristics, such as, speed, range, payload, disc loading, blade solidity, passive defense features, etc., which can be varied in order to give insight into their effects on the weight, size, and performance of helicopters. All of the characteristics are coordinated so that the effect of them on each other can be examined in context. (Author)
