Abstract : An investigation was made to test the feasibility of the use of the flexible rotor blades for a new type of ejection system to be used by pilots in military service to maneuver to safety rather than remain on the mercy of the wind in a parachute. Among designs being considered is an ejection system which works on the autogyro principle. Since prior research has already been done on flexible blades, the primary problem was to adapt them to an ejection system. Different blade configurations were tested in order to find one which would be stable through all ranges of RPM, within the structural limits of the blade and which would satisfactorily autorotate. Results indicate that the use of flexible blades on an escape system is feasible and very advantageous due to their light weight and ease of storage within the limited confines of a cockpit. The construction of a model was also undertaken which will be used to test the autorotative qualities of the blades. (Author)
