INVESTIGATION OF A PERSONNEL SEATING SYSTEM DYNAMIC TEST FACILITY (PROJECT SURVAE).
Abstract
This report presents the significant technical information and results generated by the AAI Corporation, in the study and definition of a proposed facility for conducting high energy impact testing. The performance spectrum of the facility is primarily directed toward satisfying the predicted requirements for advanced aerospacecraft seating and restraint systems expected to be in operation in the 1975-1985 time frame. Dynamic effects which could be experienced during emergency survivable crash impacts can be simulated by this facility. Velocities up to 350 fps can be attained. Deceleration of up to 200 g and onsets up to 30,000 g/sec can be provided within the spectrum of braking system capability. Acceleration of test carriages weighing on the order of 7500 to 9000 pounds and carrying up to 2000 pounds of payload would be accomplished using a vacuum tunnel concept. For the propelling force, this method utilizes a pressure gradient provided across a carriage-mounted plate or piston by the evacuation of the downstream side of a tunnel in which the carriage/payload combination is constrained to travel. Deceleration of the carriage is provided by two different systems. A hydraulic buffer is used for achieving the high g, high onset single pulses. The longer pulses are provided by a number of servo controlled friction brakes mounted to a carriage. These brakes can be preprogrammed to provide multiple pulses as well as variable pulse shapes.
