Characterization of Horizontal Impulse Accelerator Pin Profiles

摘要

Tests were run on the AFRL/HEPA Horizontal Impulse Accelerator (HIA) to document the dynamic response of 31 available metering pins. These interchangeable pins regulate the flow of gas through the HIA and produce an acceleration pulse unique to each pin. The standard 40G seat was used with a VIP-95 manikin test subject. Data collected were Sled X, Y, and Z accelerations, impact rise time, impact duration, velocity change, and onset rate. HIA operating parameters were also documented for each pin.
