GTL proposes to further the development of its SNS technology towards adoption into aerospace structures. The SNS technology is an enabler technology for the expanded use of structural health monitoring systems. It allows the large data architectures needed for these types of systems to be implemented with minimal mass and impact to structural performance. GTL will accomplish this by automating th ...

Polymer matrix composites are increasingly replacing traditional metallic materials in NASA launch vehicles due to high strength to weight ratio, manipulative properties, and corrosion resistance. However, the inspection and repair methods for these materials are considerably more complicated. For aerospace platform repairs, a composite laminate patch must be manually fabricated on-site and then ...

High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. Energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) may adversely affect not only beyond-Low-Earth-Orbit missions, but also aircraft avionics, communications, and airline crew/passenger health. It is cru ...

The program is focused on developing high temperature energy harvesting devices that can convert waste energy (primarily vibratory) such as the mechanical disturbance from thrusters as to include waste exhaust created during operational conditions. The program focus is on developing very high performance devices that are extremely robust and that can continuously operate at up to 500 C. The purpos ...

NASA has supported several instrument development efforts for exploration of Mars other extraterrestrial bodies.This exemplifies the importance of new instrument development efforts for successful advancement of NASA missions.With this in mind Laser&Plasma Technologies successfully demonstrated feasibility of integrating LIBS&Raman instruments into Optical Based Hybrid Spectroscope that meets NASA ...

Launch vehicles experience extreme acoustic loads dominated by rocket plume interactions with ground structures during liftoff, which can produce damaging vibro-acoustic loads on the vehicle and payloads if not properly understood and mitigated against. Existing capabilities for modeling turbulent plume physics are too dissipative to accurately resolve the acoustic propagation and detailed vehicle ...

As the power density of advanced engines increases, the need for new materials that are capable of higher operating temperatures, such as ceramic matrix composites (CMCs), is critical for turbine hot-section static and rotating components. Such advanced materials have demonstrated the promise to significantly increase the engine temperature capability relative to conventional super alloy metallic ...

Solid rocket motor (SRM) design requires detailed understanding of the slag accumulation process in order to: predict thrust continuity, optimize propellant conversion efficiency, predict coning effects from sloshing, and to assess potential orbital debris (slag) hazard. Current state-of-the-art models for SRM environment do not have the capability to simulate the accumulation and dynamics of slag ...

Recurring slope linae (RSL), such as those in Newton Crater on Mars, methane plumes in hazardous Martian terrain, and water ice discovered during the LCROSS experiment in the Moon?s permanently shadowed Cabeus Crater drive the need for a new generation of robotic explorers that access, probe, extract, and return resources from extreme terrains. These robots must possess sufficient system-level aut ...

Prime Photonics proposes to team with Dr. Duke of Virginia Tech to develop a multi-mode, enhanced piezoelectric acoustic emission sensing system to couple large damage events to local distribution of damage accommodation. Our system will be centered around an instrument designed to accept the output of a piezoelectric transducer sensitive to in-plane acoustic events. The signal processing path w ...
