Methodology for estimating helicopter performance and weights using limited data

摘要

A method is developed and described for estimating the flight performances and weights of a helicopter for which limited data are available. The method is based on assumptions that couple knowledge of the technology of the helicopter under study with detailed data from well-documented helicopters judged to be of similar technology. The approach, analysis assumptions, technology modeling, and the use of reference helicopter data are discussed. Application of the method is illustrated with an investigation of the Agusta A129 Mangusta helicopter.
