A novel method of fabricating carbon nanotube (CNT) reinforced polymer matrix composites is proposed. It includes growing super-aligned carbon nanotube arrays on a flat substrate, using NCSU proprietary shear pressing method to compress the grown arrays into a layer of densely packed, highly aligned CNTs inclined at an angle of several degrees to the substrate, separating the produced CNT sheet fr ...

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 ...

The physical phenomena that dominates the use of submillimeter (SMM) spectra for the analysis of missile intercepts is the rapid cooling of the post-intercept gas and debris field and its impact on the SMM spectral signatures and post-impact chemistry. It is likely that the initial high temperatures and density will result in a molecular soup that is much more complex than the atomic mixtures tha ...

The next generation of riverine craft and naval unmanned surface vehicles will require more capability, including higher payload and volume needed to carry more troops and their equipment, increased ballistic protection, more weapons, and additional mission equipment. In order to meet system integration requirements and maintain the maneuverability and agility required for survivability, these cra ...

The objective of this proposed effort is to leverage state-of-the-art modeling and simulation tools to predict and assess the performance of a novel layered material system as protection for high-value missiles when deployed in launchers and canisters. The physics-based computational tools developed and used by Corvid allow for complex material interactions to be captured to provide an understandi ...

The objective of this proposed effort is to continue the development of Corvid’s existing modeling and simulation framework to provide an innovative methodology used to predict the response of full-scale weapons systems to fast cook-off (FCO) and slow cook-off (SCO). Ammunition presents a special problem where no reliable and inexpensive sub or small scale testing capability has been identified. ...

Comprehensive testing to ascertain IM compliance for energetic systems is time-consuming and expensive. A key to this proposal is the use of high-fidelity physics based modeling and simulation tools to augment the testing programs. Modeling and simulation tools exist that can be used to address the assessment of existing and new propellants, serve as a design tool for reducing sensitivity, and a ...
