Rotorcraft Weight Estimates Utility

This is a calculator that generates rotorcraft weight estimates based on targeted helicopter attributes. Source code is here. Note that the methods are derived from Rotorcraft Performance, Stability, and Control by Raymond W. Prouty (1986) and from IMPACT OF EMERGING TECHNOLOGY ON THE WEIGHT OF FUTURE ROTORCRAFT by R. A. Shinn (May 16, 1984).
