Reduced mass materials are critical to the success of aerospace systems. Thus, large air and space structures can benefit from lightweight composite materials. However, their adoption is impaired by the lack of a robust, cost-effective fabrication process, principally because the autoclaves used to consolidate composite laminates are so expensive for large parts. This program develops for US aeros ...

Environmental degradation of adhesive bonds of composite or metallic structures affects predominantly the adhesive/adherent interface by decreasing the number of molecular bonds between the adhesive and the substrate. The objective of the proposed Phase I work is to perform a feasibility study of a novel non-linear ultrasonic method for quantitative characterization of molecular bond density with ...

The proposed Phase 2 project consists of the physical integration of our Phase 1 small, compact exciter with a "flight like" igniter or spark plug capable of hot-fire testing. The exciter/igniter unit will operate to a pre-established subset of expected flight performance requirements established and met in Phase 1. The exciter/igniter unit will physically integrate the exciter electronics with ...

In Phase 1, CRG demonstrated the feasibility of a novel approach to prepare cyanate ester based elastomers. This approach polymerizes in-situ siloxane within a reactive elastomer precursor matrix in order to achieve an elastomeric material with highly tunable and desired mechanical properties. This methodology shows great potential in materials development for applications such as space deployabl ...

Cornerstone Research Group Inc. (CRG) will develop new shape memory polymer (SMP) deployment mechanisms for actuating thermal protection system (TPS) panels to create a deployable, large surface area aeroshell. This innovation will exploit Veriflex(R) -- CRG's high-performance SMP material -- to create a low-mass actuation system for a deployable aeroshell design. Veriflex(R)-based mechanisms wi ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

The incandescent lamps used in the green threshold lamps that form a line on the front end of an airport runway, have relatively short lives and require constant maintenance. The green filters used in front of the lamps transmit only about 20% of the light. Green light emitting diodes (LEDs) have been improved recently and are reaching brightness levels making it possible to use them in traffic ...

During the Phase II Lunar Health Monitor program, Orbital Research will develop a second generation wearable sensor suite for astronaut physiologic monitoring. The low profile system will be appropriate for both Extravehicular activities (EVA) and Intravehicular activities (IVA) monitoring scenarios. The EVA and IVA wearable platforms are capable of monitoring a complete physiologic profile of ove ...

This proposal identifies a flight test program on the F-15B at NASA Dryden to obtain off-design performance of high-speed inlets that incorporate a unique variable geometry system. The proposed effort accomplishes two objectives; validation of engine face distortion prediction by complex CFD codes and validation of a unique new approach to variable geometry for high-speed inlets. For supersonic cr ...
