This NASA Phase I STTR effort will establish the feasibility of developing a compact broadband near to mid-IR programmable optical comb for use in laser based remote sensing and communications. The comb generator will use a waveguide-based optical parametric gain block technology that can have ultra wideband (>250nm) operation with very high gain (>25dB) in a very compact footprint. This approach ...

To provide reliably secure communications, development of quantum optical devices for encrypted ground-to-space communications is a necessity. The overall goal of this NASA effort is to develop and deliver efficient, single-pass quantum optical waveguide sources capable of backward quasi-phase-matched interactions for generation of high purity photon pairs for use in an on-demand photon source to ...

This SBIR Phase I effort proposes to establish the feasibility of developing a UV Planar Lightwave Circuit (PLC); a compact, highly efficient, waveguide-based frequency conversion module for the generation of phase modulated UV radiation for use in multi-wavelength lidar applications such as NASA LaRC's HSRL program. The proposed module will provide phase modulated 355 nm radiation for calibratio ...

This Small Business Innovation Research Phase I effort will investigate the feasibility of using electro-optic (EO) beam scanning element to control coupling into a fiber as a fiber coupled pulse shaper. The goal of the pulse shaper is to reduce a 4-6ns pulse to 0.4-0.6ns pulse at 1064nm and/or 532nm at input powers at the 2mJ level. The highest utility of the proposed pulse shaper is its progr ...

Cornerstone Research Group, Inc. (CRG), proposes to demonstrate feasibility in the reduction of noise attributed to drainage slots in jet engine acoustic liners. This will be accomplished through the development of design rules for optimum slot design and the implementation of adaptive material technologies. CRG proposes to bring this technology to a technology readiness level (TRL) 2 after the Ph ...

Cornerstone Research Group, Inc. (CRG), proposes to develop self-deploying, composite structures for lunar habitats, based on CRG's VeritexTM materials. These structures will provide a rigid, durable habitat that will reduce the risk of mechanical failure due to crew or environmentally induced damage compared with inflatable structures that are more susceptible to punctures and damage from microme ...

CRG's shape memory polymer (SMP) Bladder Tooling is a cutting-edge manufacturing technology that can meet the manufacturing needs of the Ares launch vehicles. This process provides labor savings, weight reductions, and reliable manufacturing results for fabricating complex composites. SMP bladder tooling eliminates the transferring process by operating as both a rigid lay-up mandrel and an elastic ...

The proposed innovation is the replacement of existing test stand and parking lot fixtures with current SSL LED technology. The replacement fixtures will reduce energy consumption, generate less heat and provide maintenance free operation for over 50,000 hours. An explosion-proof fixture is capable of containing an internal combustion event without allowing flames or hot gasses to escape to the s ...

The objective of the proposed work (Phases I and II) is to develop uncertainty quantification methodologies and software suitable for use in CFD simulations of aerodynamic flows, ranging from sub-sonic to hypersonic. We will address both pressure and density-based methods, as well as the class of algorithms addressing all-Mach number flows. The software developed here will be based on an existing ...

The overall objective of this proposal (Phases I and II) is to develop a robust and accurate solver for fluid-structure interaction computations capable of addressing multi-body flexible structures as well as rigid body motion. The fluid flow solution will be performed using our unstructured solution-adaptive flow solver TETHYS. We propose to develop a structural solver based on the Galerkin finit ...
