Military Environmental Control Units (ECUs) represent one of the dominant energy users in forward operating environments, and significant effort is being made to improving overall ECU efficiency [1]. Reducing overall Size, Weight and Power (SWaP) of military ECUs is complicated by the transient, yet predictable, nature of the thermal demand profile over the course of a typical daily usage cycle, ...

ABSTRACT:Field Programmable Gate Arrays (FPGAs) and other complex microelectronic devices are critical to Air Force advanced electronic systems. As the sophistication of supply chain counterfeit infiltration continued to grow, criminal elements and adversarial states have expanded the use of advanced techniques that defeat conventional screening methodologies to exploit supply chain weaknesses fo ...

Future hypersonic vehicles will be required to fly extended, long term trajectories where the bodies must exhibit high lift-to-drag (L/D) ratios. The need for reduced drag means that the nosetips and leading edges must have small radii, shallow wedge angles, and be erosion resistant. Desirable dimensions include a nose radius on the order of 0.040 inch and a wedge half angle of about 3. This radiu ...

Welding of HPS70W is well understood when using submerged arc welding (SAW) and shielded metal arc welding (SMAW) techniques. A Welding Advisory Group (WAG) which consisted of technical advisors from the Navy, AISI, and FHWA, major filler metal manufacturers, and steel producers determined the guidelines for welding HPS70W. As a result, comprehensive guidelines and welding procedures exist for SAW ...

This topic addresses the problem of robustly commanding and controlling unmanned ground vehicles operating in complex, unstructured environments. Current approaches to this task rely on dense scene reconstruction from a variety of sensor data such as LIDAR and video imagery. Scene representations are then relayed to a remote human operator who provides commands at varying levels of supervisory con ...

Recent advancements in sensor simulation tools [2] have improved our ability to model radar, lidar, camera, and GPS with software/hardware in the loop. Of course, our ability to model the physics of heavy trucks [3] is quite mature as well. To address the challenge of developing the STE, we will provide our autonomy algorithms as Government Furnished Equipment (GFE). The focus of this topic ...

ABSTRACT: This Small Business Innovation Research (SBIR) Phase II project proposes to develop and demonstrate a test apparatus for determining the minimum hot surface ignition (HSI) temperature of flammable liquids in aircraft operating conditions. Flammable liquids leaking onto hot surfaces, such as those in an aircraft engine bay, present fire hazards and risks to personnel and equipment. To pro ...

Piasecki Aircraft (PiAC) proposes to continue development and testing efforts of the Whimbrel UAS, a low cost, expendable, air-deployed weather survey unmanned aircraft system. The Whimbrel UAS, a low cost, expendable, air-deployed weather survey unmanned aircraft system. The Whimbrel USA has been developed to support the Tropical Cyclone Boundary Layer mission requirements and contains sensors an ...

A novel bidirectional power converter module is proposed utilizing a new converter topology enabling true bidirectional operation by intelligent control of modified switched mode power architecture. This architecture facilitates the creation of a multi-t Benefits

Under a Phase II program, DRS Scientific will build, test, and deliver a new type of Acousto-Optic Tuned Filter (AOTF) hyperspectral imager that is compact, rugged, and inexpensive, has no moving parts, and is fast and sensitive. It will cover 8-12 micron wavelength range with 10 wavenumber spectral resolution or finer, and will have micro-Flick sensitivity with a cooled camera, and
