Annex A. Science And Technology Objectives (STOs)
Army Science and Technology Master Plan (ASTMP 1997)

III.D.19. Subsystem Technology for InfraRed Reduction (STIRR). The focus of this STO is on the development, integration, and demonstration of improved RWV survivability through total aircraft thermal signature management. Technology objectives aimed at selectively reducing and balancing both the thermal emissions and engine/plume contributors to total aircraft IR signature are key components of this STO. Advances in infrared technologies that include the development of partial and full imaging capabilities on near term threat missile systems coupled with the proliferation of older yet still lethal surface-to-air missile systems have resulted in the need for a better equipped, lower IR signature aircraft. Concurrent with the increasingly lethal battlefield, today’s fleet aircraft are assuming additional responsibilities which oftentimes result in additional on-board "heat-producing" equipment and greater engine power requirements.

Several technology initiatives have been identified as priorities based on current and expected future infrared advancements. In support of aircraft thermal emissions reduction, this STO will achieve development and measurement of advanced, multi-spectral (visual-through far-IR) airframe coatings that are compatible with radar absorbing amterials/structures, and development of state-of-the-art, low-cost, lightweight thermal insulative materials by FY99. Efforts to cool helicopter engine/plume contributors have also been identified. Advanced engine suppression concepts will be fabricated and demonstrated on both a sub- and full-scale level by FY00. Balanced thermal signature reduction will be achieved and demonstrated on a RWV by FY01. A goal of 35 percent reduction in aircraft IR signature is attainable and anticipated which will support a RWV payoff of 40 percent increase in the probability of survival.

Supports: AH-64, UH-60, RAH-66 upgrades, ICH and JTR developments as well as other service aircraft.
