Inlet distortion generation for a transonic compressor
(Monterey, California. Naval Postgraduate School, 2004-09)
A single-stage transonic research compressor and test rig are to be used to obtain data on the effect of inlet flow distortion on compressor (and therefore engine) stall. Auxiliary injection was examined as a technique for ...
Processing and characterization of NiTi Shape Memory Alloy particle reinforced Sn-In solder
(Monterey, California. Naval Postgraduate School, 2006-12)
of the solder. In this thesis, a new fabrication process for incorporating NiTi particles (10 vol.% NiTi) into Sn-In solder (80Sn-20In) using liquid phase sintering has been developed. The microstructures of the solders ...
Experiments with the REMUS AUV
(Monterey California. Naval Postgraduate School, 2004-06)
This thesis centers around actual field operations and post-mission analysis of data acquired using a REMUS AUV operated by the Naval Postgraduate School Center for Autonomous Underwater Vehicle Research. It was one of ...
Investigation and development of oil-injection nozzles for high-cycle fatigue rotor spin test
(Monterey, California. Naval Postgraduate School, 2005-03)
Resonant excitation tests of rotor blades in vacuum spin pits using discrete oil jets showed that impact erosion of the blades could limit test times, but lower excitation amplitudes were produced using mist nozzles. ...
Thermo-mechanical response of monolithic and NiTi shape memory alloy fiber reinforced Sn-3.8Ag-0.7Cu solder
(Monterey, California. Naval Postgraduate School, 2005-09)
In electronic packaging, the reliability of solders is a critical issue, since serve as both electrical and mechanical connections. The most common failures arise from the thermo-mechanical fatigue (TMF) of solders, due ...
Stability analysis of a towed body for shipboard unmanned surface vehicle recovery
(Monterey California. Naval Postgraduate School, 2005-03)
As the U.S. Navy develops new technologies which enhance automation and reduce crew size onboard naval vessels, unmanned vehicles will become increasingly valuable in conducting maritime operations. Effective launch and ...
Effect of pressure and temperature on oil mist sprays used for blade excitation in high cycle fatigue testing
(Monterey California. Naval Postgraduate School, 2006-06)
The flow patterns of two oil mist nozzles used in rotor blade excitation experiments were characterized using a Laser Doppler Velocimeter (LDV). Both nozzles were operated in a vacuum test chamber and velocity measurements ...
Study of micro-sized technology, micro air vehicles, and design of a payload carrying flapping wing micro air vehicle
(Monterey California. Naval Postgraduate School, 2006-03)
There has been recent interest by the military to have platforms capable of operating close to a point of interest without being detected while providing critical surveillance. By providing information that is not readily ...
Fluid-structure interaction effects resulting from hull appendage coupling
(Monterey California. Naval Postgraduate School, 2005-09)
In previous work conducted in the modeling and simulation of ships subjected to underwater explosions, there has been some debate over the influence that hull appendages have upon the dynamic response of a multi-degree-of-freedom ...
Friction stir processing parameters and property distributions in cast nickel aluminum bronze
(Monterey, California. Naval Postgraduate School, 2006-12)
Cast nickel-aluminum bronze (NAB) alloy is specified for many marine applications, including ship propellers, due to its excellent corrosion-resistance combined with acceptable mechanical properties. Friction stir processing ...
