In this PhaseII SBIR effort, Corvid Technologies completes the development of an innovative approach for solving Unstructured Fixed Grid Navier-Stokes CFD flow simulations. The proposed approach developed at Corvid is referred to as the Virtual Geometry Insertion (VGI) technique. This approach allows for the virtual insertion of arbitrary geometric components into a standard CFD analysis. This g ...

Atmospheric disturbances are a major performance-limiting factor in long-range optical systems. In particular, for the Airborne Laser (ABL) the ability of distinguish targets from a long distance is crucial for mission success. Despite the progress in optics and sensor technology, blurring in long-range imaging caused by atmospheric movements and density changes will remain an issue. Digital si ...

The Phase 2 objective is to provide NIST with a modular gauge head unit equipped with InsituTec's standing wave probe technology. The complete gauge head unit will be retrofitted to the NIST M48 which is one of the most precise measuring machines in the world. This unit will enable NIST to achieve the agency's program goal in dimensional metrology which is to provide microscale measurement capacit ...

A recently developed nonlinear controller called theta-D and the Higher Order Sliding Mode (HOSM) control are the centerpiece around which an Integrated Guidance and Control (IGC) scheme and a nonlinear filter technique are built to enhance the lethality of hit-to-kill interceptors and offer a means to increase the maneuver ratio advantage. This proposal includes the development of a 6DOF based I ...

Improving efficiency and reliability of GaN-based FETs is paramount in enabling system insertion, both of which are limited by thermal effects and self heating in the devices. One factor limiting high voltage and high efficiency operation of GaN HEMTs is leakage current between the gate and drain at high drain bias. Pure screw dislocations arising from the lattice mismatch at the SiC substrate and ...

Large area semi-insulating GaN has the potential to impact the commercialization of many technologies such as power transistors, high frequency microwave amplifiers, and high-speed, high-power switching components. One of the limiting factors in many of these applications is the lack of commercially available large diameter substrates. This program will develop 4" diameter semi-insulating GaN su ...

In this program, we will combine commercially available AlGaN/GaN on Si FETs with short gates such that the high frequency performance (X-band and higher) can be significantly increased. The AlGaN/GaN material system has significant advantages over the incumbent technology for X-band applications; specifically, AlGaN/GaN FETs have much higher power density which translates into broader bandwidth. ...

Components used in missile propulsion and control systems such as Throttling Divert and Attitude Control Systems (TDACS) are susceptible to damage and degradation under the harsh operating conditions. Notwithstanding such conditions, a monolithic variant of the “NZP” ceramic has been successfully utilized by Aerojet for TDACS components in MDA’s GMD and SM3 missiles. For more advanced soli ...

In this program, Voxtel will demonstrate SOI-CMOS imagers for high-performance star tracking applications. Fabricating CMOS imagers on SOI wafers, allows the device and detector layers to be separated with an insulating layer, so each can be individually optimized and operated with separate ground returns. High QE and high MTF come from backside illumination and depleting the entire volume of dete ...

A highly reliable InAlAs/InGaAs avalanche photodiode (APD) focal plane array (FPA) will be developed to replace the electron-bombarded charge-coupled device (EBCCD) camera presently used for Airborne Laser (ABL) wavefront sensing applications. Based on technology with a nominal lifetime of 105 hours of continuous operation, Voxtel’s monolithic solid-state architecture is both more manufacturable ...
