Analysis of harmonic distortion in an integrated power system for naval applications
This research quantifies the voltage distortion over the broad range of operating conditions experienced by a Naval warship. A steady state model of an Integrated Power System (IPS) was developed in a commercially available ...
High speed linear induction motor efficiency optimization
One of the reasons linear motors, a technology nearly a century old, have not been adopted for a large number of linear motion applications is that they have historically had poor efficiencies. This has restricted the ...
Development of a procedure for the selection of candidate vessels of opportunity in support of the submarine rescue diving and recompression system
The U.S. Navy's new system for rescuing stranded submariners, the Submarine Rescue Diving and Recompression System (SRDRS), utilizes a tethered, remotely operated Pressurized Rescue Module (PRM) deployed and controlled ...
A method of increasing the kinematic boundary of air-to-air missiles using an optimal control approach
(Monterey, California. Naval Postgraduate School, 2000-09-01)
Current missile guidance laws are generally based on one of several forms of proportional navigation (PN). While PN laws are robust, analytically tractable, and computationally simple, they are only optimal in a narrow ...
Determination of diesel engine cylinder gas torques from speed fluctuations with a high-fidelity crankshaft torsional model
(Monterey, California. Naval Postgraduate School, 1998-12-01)
An experimental investigation was conducted to develop a method of predicting cylinder indicated torques in a reciprocating engine by measurement of crankshaft angular velocity fluctuations. Cylinder indicated pressures ...
An analysis of spacecraft dynamic testing at the vehicle level
(Monterey, California. Naval Postgraduate School, 1996-06)
The US space industry has accumulated a vast amount of expertise in the testing of spacecraft to ensure these vehicles can endure the harsh environments associated with launch and on-orbit operations. Even with this corporate ...
Coherent/noncoherent detection of coherent optical heterodyne DPSK-CDMA and MFSK-CDMA signals
(Monterey, California. Naval Postgraduate School, 1991-12)
The system performance of a coherent optical heterodyne communication system is analyzed for MFSK-CDMA and DPSK-CDMA signaling. The analysis determines the effect that receiver thermal noise, photodetector shot noise, ...
Real time adaptive control of an Autonomous Underwater Vehicle (AUV)
(Monterey, California. Naval Postgraduate School, 1989-09)
In this research the problem of designing a controller for the dive maneuver of an Autonomous Underwater Vehicle (AUV) is addressed. The highly nonlinear nature of the vehicle dynamics and the requirement for the fast ...
Automatic control of ship deceleration
(Monterey, California : Naval Postgraduate School, 1978-03)
Various methods have been introduced for dynamic braking of ships. Depending on the prime mover and transmission system, dynamic braking is accomplished by electric power dissipation (in electric driven ships) or clutches ...
Investigation of heat transfer in straight and curved rectangular ducts using liquid crystals thermography
(Monterey, California. Naval Postgraduate School, 1977-06)
A rectangular cross section channel with both straight and curved test sections was used to investigate the effect of Taylor-Goertler vortices on the heat transfer from the curved section by comparing the results with those ...
