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-resolving 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 loop. ...

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 ...

The innovation proposed is an axially operated, high efficiency, low mass cryogenic valve. This innovation, termed Venturi Off-Set Technology (VOSTtm), addresses four critical needs for effective storage, transfer and use of cryogens in aerospace. These are: thermal isolation to minimize heat leakage,low pressure drop to accommodate high flows without cavitation, minimal mass and space requirement ...

This innovation is concerned with the fabrication of a novel morphology of LiMnO2 to be implemented in revolutionary composite cathode for lithium ion rechargeable batteries. The proposed cathode material and novel fabrication process will overcome capacity fading problems inherent in LiMnO4, exhibit greater utilization of its theoretical capacity, show exceptional cycleability and provide a vehic ...

GPS receivers are heavily used in aviation for both visual and instrument flights. There is a need for a backup system so that enroute and non-precision approaches can be flown without reliance on ground based systems should GPS be unavailable. We propose to use barometric pressure, airspeed, low-cost inertial sensors, three-axis magnetometer along with high-fidelity geomagnetic models, and an ...
