Characterization of Vertical Deceleration Tower Plunger Profiles

摘要

Tests were run on the AFRL/HEPA Vertical Deceleration Tower (VDT) to document the dynamic response of twelve available plungers. The standard seat fixture was used with an ACES II ejection seat, seat pan and seat back. A 50th percentile HYBRID 3 manikin restrained with a PCU-16P harness was used for all tests. Data collected were Carriage X, Y, and Z acceleration. Processed data included impact rise time, impact duration, velocity change, and onset rate. These characteristics were documented for Carriage Z axis accelerations of 6G, 8G, 10G, 12G, 15G, and 20G.
