Abstract:

This test represents an effort toward developing, evaluating and recommending for ANU listing an electrically powered resistive heating system RHS to provide Special Warfare divers with adjunct thermal protection while conducting SDV operations. Formerly known as the EXOTEMP and Active Thermal Protection System ATPS, the RHS is being developed and manufactured by Steadfast Technologies Brandon, FL. The RHS dry suit liner-long-sleeved body suit with integral socks is made of a thin, stretchy knit fabric. The entire suit has electric resistance tinsel wires stitched to it in patterns that course along the longitudes of the trunk, arms, and legs and cover the tops of the feet. Five-finger electric gloves that plug into an outlet at the end of each sleeve have wires stitched to them on both sides of the hand and the backs of the fingers. Power output to the suit is regulated via voltage sensing circuitry that measures battery voltage and regulates the power output duty cycle to deliver approximately 270 watts of heat to the diver. Electrical protection, conforming to AODC 035 specifications, is provided by Ground Fault Interrupter GFI circuitry.
