Helmsman's Recording Accelerometer

摘要

Report developed under SBIR Contract Special Operation Forces (SOF) must meetmission requirements in all types of sea conditions. High performance craft, forced to operate in rough sea, create rapid onset of high levels of fatigue for craft occupants, resulting in reduced mission performance and creating a higher potential for injury of the craft occupants. The objective of this program is the development of a Helmsman's Recording Accelerometer (HRA) for instrumentation on high performance craft. The HRA is needed to provide the helmsman with real time quantitative acceleration data and to record craft operation data that will allow for post-mission analysis. A Phase II program is required for implementation of the HRA. An HRA test unit, fabricated to meet Phase I objectives, requires operational testing to ensure that the HRA provides data that is beneficial and optimally formatted for the helmsman in controlling the craft. Field tests are essential to establish post-mission database requirements for the HRA and final HRA design requirements. The database is needed to evaluate passenger safety, to develop improved mission operations, to obtain craft performance rating, to identify craft and personnel performance limits, and for the development of effective maintenance. The HRA database will serve to enhance future mission planning.
