Flight Path Calculations for a Helicopter in Autorotative Landing

摘要

A computer simulation program has been developed for the calculation of theflight path for a helicopter in autorotative landing. The computation method is based on the energy method where one source of energy can be exchanged for that of other sources. Interviews with helicopter test pilots have provided a review of the practical techniques and procedures to accomplish a safe autorotative landing. These interviews have been determined and translated into usable procedures for a control model. The autorotative flight can be investigated by variation of the pilot inputs, the pilot cues and the initial and boundary conditions. This model can be used to analyze the most optimal performance of an autorotative landing by manual iterations.
