A critical military requirement exists for a fast, cost-effective, six-degrees-of-freedom (6DOF) technology that can track a pilot's helmet though rear-projection screens and is immune to distortion and interference from scatterers of magnetic/electrical energy. Building upon Phase I research that demonstrated feasibility of projecting light energy through graphics projection screens, Ascension T ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this design cycle many times, with routine tasks performed by engineers in a trial-and-error manner. ...

The multiple-view genlocked camera (MVGC) developed and demonstrated duringthe first phase of this program will be extened to the long infrared domain. In addition, real-time structure from motion (SFM) and video-based anvigation algorithms will be coded on the Phase I and Phase II ontrol computers. Captive Flight Tests in winter and summer conditions will be executed to gather data and to evalu ...

Space-based radar (SBR) requires multiple RF power amplifiers (PAs) to drive phased-arrays antennas. Control of the beam direction requires an amplitude range of 22 dB, and coupling between elements results in load impedances with significant mismatch. Both factors make conventional linear RF PAs very inefficient. The proposed approach employs a high-efficiency RF PA, class-S modulator, and e ...

75333-Nano-indentation is the primary technique for assessing the nanomechanical behavior of small volumes of materials. With this technique the load required to produce a given displacement into the sample by a sharp diamond tip is measured, and the hardness of the material is derived. However, the microstructural behavior that causes the mechanical response of the material is not often readily ...

The overall goal of the proposed research is to develop a comprehensive, efficient, and well-validated model for the prediction of the shape and thermal history of components manufactured using Laser Additive Manufacturing (LAM) processes. The proposed model will use a combined Eulerian-Lagrangian treatment for analyzing the three-dimensional gas-particle flow. Analysis of radiative heat exchange ...

The development of Innovative Technologies for Reducing Unexploded Ordnance (UXO) provides critical technology to eliminate Unexploded Ordnance (UXO) with the potential to maim and kill. Once deployed, if the fuze did not function as designed, it would become safe and unable to detonate. The proposed technology would eliminate the highly sensitive nature of UXO's that exist today and eliminate t ...

Lockheed Martin delivered the first operational F-16 Fighting Falcon to the United States Air Force in January 1979. With more than 10 miles of wiring packed into an aircraft just 49 feet long, the aging F-16 suffers from intermittent power wire failures that pose a significant fire hazard. These failures often occur when a cable's degraded jacket enables a water droplet or metal shaving to temp ...

Newer, smart transducers that conform to the IEEE 1451 standards will be used in new and legacy Instrumentation Support Systems (ISS)s allowing the ISSs to know exactly what is available on a test vehicle and also the coordination of the instrumentation setup, ground station setup, full pre-test checkout and dynamic error correction. Changes in the operational scenarios of ISS as a consequence of ...

As new technologies trend towards lower supply voltages to reduce power consumption at higher speeds their interfaces become less compatible with older legacy systems. In space electronics the challenge is greater since components and systems must also be radiation hardened. Therefore, there exists a need for unique radiation hardened interface devices that transparently convert from one type of ...
