The objective of this proposal is the development and demonstration of a cost-effective high-fidelity aeroacoustic design tool for future commercial supersonic nozzle designs and installations. Although eddy-resolvingnbsp; CFD methods for computing high-speed jet noise are available, such methods are computationally expensive and are currently deemed impractical for use in a design optimization lo ...

The concept proposed is that of an innovative turbopump using hydrogen peroxide to drive the turbine. The turbopump has a unique feature in that it has an integral electric generator used to generate electricity and power an external fuel pump.By using hydrogen peroxide decomposed over a catalyst pack only one fluid can be used to drive the turbine. Typically, a turbopump combusts a fuel and an ox ...

NASA is developing new vehicles for human space flight. The Orion crew module is a reusable capsule that provides a habitat for the crew and facilitates exploration of the Moon, asteroids, and Mars. The Space Launch System (SLS) is a heavy lift system and is part of NASArsquo;s deep space exploration plans. The SLS will carry humans beyond low Earth orbit and will deliver elements of the Lunar Orb ...

The concept describes a booster for a launch vehicle that is simpler to make, transport and launch than current launch vehicles. It is composed of two major components. The first being a booster structure and the second being a liquid rocket engine that uses a thermodynamic cycle that is a combination of two common cycles.Furthermore, the engine is actually fairly simple when compared to modern li ...

A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

Space operation places extra physical and structural demands on the power components, including capacitors. Nanostructured dielectrics offer the opportunity to tailor the dielectric material on the nanometer scale to provide tremendous improvements in electrical, mechanical, and thermal properties, and enable high-temperature, high-energy-density, and high-voltage capacitors. In this project, the ...

NASA is planning to return to the moon in 2020 to explore thousands of miles of the moon?s surface with individual missions, lasting six months or longer. Surface mobility is critical to outpost buildup and exploration activities, where the change in the vehicle weight between unloaded and loaded cargo conditions and travel over rough terrain can adversely affect the ride handling conditions and ...
