Environmentally durable material systems capable of operating at temperatures from 1500 to 3000?C while maintaining structural integrity are enabling for future hot structure hypersonic vehicles. State-of-the-art ceramic matrix composite CMC's and other established refractories lack stability at these high temperatures. The plasma transferred arc (PTA) additive manufacturing (AM) process has dem ...

Transparent armor is very important to the survivability and situational awareness for the crews of modern land, marine or aviation vehicles. Additionally to the common armor requirements (low areal density and high ballistic performance) transparent armor should provide high infrared and visual transmittance. Ceramic ballistic windows meet these requirements, but they often suffer from unaffordab ...

A hardware/software solution for autonomous reporting of flight operations of a UAS is proposed. Such a system would enable the UAS to report identity, position, and other information to local human and autonomous traffic and air traffic controllers in an autonomous manner, in legacy terminology. This will improve the overall safety of UAS operations, and lead to easier integration of UASs into th ...

THE DEVELOPMENT OF A LOW COST, 3-AXIS, NUMERICALLY-CONTROLLED, OPTICAL GENERATOR SUITABLE FOR USE IN GRINDING GLASS OR CERAMIC PARTS, AS WELL AS FOR MACHING METALS TO OPTICAL TOLERANCES IS DESCRIBED. THIS INNOVATIVE DESIGN USES ROTARY BEARINGS ON ALL THREE AXES BECAUSE OF THEHIGH ACCURACY AND LOW COST PROVIDED. THE NC MACHINE WILL HAVE THE CAPACITY TO GENERATE EITHER ROTATIONALLY SYMMETRIC OR ASYM ...

We propose an energy and space efficient high power continuous wave (cw) narrow linewidth broadband fiber Raman amplifier (FRA) with spectrally tunable multi-Watt-level average power output in the near and shortwave infrared (1080 – 2000 nm) that can be used in remote sensing systems on both atmospheric and terrestrial space-borne platforms. The all-fiber amplifier design concept for power am ...

The overall objective of this Phase I project is to develop a nonlinear trim module in FUN3D for enabling the determined and over-determined trim analyses to be performed by FUN3D with static aeroelastic effects. Based on an optimization formulation, the over-determined trim analysis can determine the optimum control surface scheduling of multiple control surfaces to achieve the best aerodynamic e ...

Atmospheric methane is the second most important anthropogenic greenhouse gas. The overtone lines of methane at 1.65 micron are well suited for remote sensing of atmospheric methane in the Earth's atmosphere. NASA have already demonstrated ground-based and airborne methane detection using Optical Parametric Amplifiers at 1651 nm using a laser with a narrow linewidth. In this setup a single frequen ...
