Sponsored by NAVAIR, Accudyne Systems completed a Phase 1 SBIR program, developing an equipment and process concept for cost-effective fabrication of composite rotary wing main rotor blade spars. The CH-53K spar was the study focus. The recommended work cell concept combines automated tape placement, woven fabric placement, and pick and place of 45° parallelograms to layup plies, then debulk and ...

Long-wavelength infrared (LWIR) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in LWIR. Despite the enhanced wavelength coverage, the GaSb/InAs type-II Strained Layer Superlattice (SLS) detector still exhibits relatively high surface leakage current and its associated noises. With an industrially proven nano-material, we propose ...

Modern aircraft include numerous RF systems and associated antennas of diverse types. The designed performance of antennas is typically degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired interference via antenna-to-antenna coupling. These conditions present serious challenges for engineers tasked with i ...

Delcross Technologies proposes to develop an automated measurement system (AMS) that will characterize the spectral profile of transmitters and receivers while minimizing manual labor. Modern RF systems can utilize thousands of channels, which makes a manual measurement system impractical for characterizing such devices. The purpose of the AMS is to create a practical process for RF system charact ...

Physics-based modeling and simulation tools for predicting electromagnetic interference (EMI) and vulnerability (EMV) between RF systems are playing an increasingly important role in system level performance predictions. In order to accurately capture all of the complexity associated with RF systems on a modern military platform, very sophisticated multi-physics simulators using models of multiple ...

Commodity graphics processing units (GPUs) offer tremendous computational throughput for relatively little cost. They have been shown to outperform microprocessors in the important metrics of FLOPS/dollar, FLOPS/Watt, and FLOPS/unit space and have already been applied to a wide range of numerically intense problems. In Phase I of this project, we demonstrated their potential to enhance complex C ...

The ultimate goal of this Commercialization Pilot Program (CPP) effort is to design, build, and integrate flight-ready custom electronics for a 220-channel MMW distributed-aperture imager. This work bases on a previous SBIR project, in which we constructed a single-channel prototype of the phase control electronics in a laboratory (breadboard) environment. To enable control of a 220-channel system ...

The proposed Phase II effort will focus on the fabrication and testing of high performance 640x512 long wavelength infrared (LWIR) type-II strained layer superlattice detector arrays. The effort will start with the modeling of devices and arrays, followed by improving the understanding of bulk defects to enhance carrier lifetimes. Passivation studies will continue based on the Phase I foundation, ...

The goal of this proposed project is to design, fabricate and characterize ultra-low-noise amplifiers for radar and signal intelligence applications. High frequency, wide bandwidth signals have several advantages in applications ranging from high data rate communications to high resolution radar. However, the biggest challenge to realizing these systems is limitations to the amplifier noise perfor ...

Traditional Cathodoluminescence (CL) tools are limited to the Near Infrared (NIR) region of the electromagnetic spectrum. Commercially available NIR CL tools are useful for studying wide bandgap semiconductors like CdTe. However, narrow gap materials such as Mid and Long Wavelength infrared (MWIR and LWIR) HgCdTe have spectral energies outside the limits of traditional CL tools. A proposal based o ...
