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 ...
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 ...
Examination of flow around second-generation controlled diffusion compressor blades in cascade at stall
(Monterey California. Naval Postgraduate School, 2004-06)
The flow around second-generation controlled-diffusion blades in cascade at stall was examined experimentally through the use of a two-component laser-Doppler velocimeter. Blade surface pressure measurements were also ...
Evaluation and analysis of DDG-81 simulated athwartship shock response
(Monterey, California. Naval Postgraduate School, 2004-06)
In 2001 the USS WINSTON CHURCHILL (DDG-81) was subjected to three underwater explosions as part of a ship shock trial. Using the actual trial data from experiment and three-dimensional dynamic models of the ship and ...
Identification of deformation mechanisms during bi-axial straining of superplastic AA5083 material
(Monterey, California. Naval Postgraduate School, 2004-06)
This study evaluated dome test samples of a superplastic AA5083 aluminum alloy deformed at nominally constant strain rates under biaxial strain conditions. Dome test samples resulted from gas-pressure forming of sheet ...
The isothermal deformation of nickel aluminum bronze in relation to friction stir processing
(Monterey, California, Naval Postgraduate School, 2004-06)
The extreme strain, strain rate and temperature gradients during Friction Stir Processing (FSP) render measurement of key parameters in the stir zone infeasible with common methods. The objective of this research was to ...
Autonomous visual tracking of stationary targets using small unmanned aerial vehicles
(Monterey California. Naval Postgraduate School, 2004-06)
A control system was developed for autonomous visual tracking of a stationary target using a small unmanned aerial vehicle. The kinematic equations of this problem were developed, and the insight obtained from examination ...
Parametric studies of DDG-81 ship shock trial simulations
(Monterey California. Naval Postgraduate School, 2004-03)
Evaluations, otherwise known as ship shock trials, have been conducted in order to determine the seaworthiness of each new class of ship commissioned in the U.S. Fleet. While beneficial in determining the overall survivability ...
