Estimation of sonobuoy position relative to an aircraft using extended kalman filters.
(Monterey, California. Naval Postgraduate School, 1979-09)
In airborne anti-submarine warfare there is a need to more accurately determine the positions of sonobuoys on the surface of the vater. This report develops two algorithms which employ extended Kalman filters to determine ...
Prediction and control of residual stresses and distortion in HY-130 thick pipe weldments
(Cambridge, Massachusetts; Massachusetts Institute of Technology, 1979-05)
In order to validate existing techniques for computer simulation of the welding process, an experiment is designed and carried out in which seam and girth weld are produced on a high strength steel cylinder. Fabrication ...
Compressive fatigue in glass and graphite reinforced composites
(Cambridge, Massachusetts; Massachusetts Institute of Technology, 1978-06)
The characteristics of compressive fatigue failure are described for unnotched laminates, with the following rank ordering by compressive strengths determined: [0 degrees/90 degrees] Graphite Epoxy, [ 0 degrees/+ 45 degree/90 ...
A comparative analysis of naval auxiliary and merchant ship design
(Cambridge, Massachusetts; Massachusetts Institute of Technology, 1978-05)
Naval auxiliary vessels carry considerably less cargo than commercial vessels and are significantly more costly to build. By comparing Naval Auxiliary vessels with commercial vessels which carry cargo of a similar nature ...
Underwater welding in the deep sea.
(Massachusetts Institute of Technology, 1978-05)
A summary of underwater welding methods presently in use or under development are reviewed in order to determine which methods have possible application to deep sea use (depths greater than 1000 feet). Studies on one of ...
Marine steam condenser design using numerical optimization
Two separate computer codes were coup led with a constrained function minimization code to produce automated marine condenser design and optimization programs of vastly different complexity. The first program, OPCODE1, ...
Experimentally determined effects of educator geometry on the performance of exhaust gas eductors for gas turbine powered ships.
(Monterey, California. Naval Postgraduate School, 1977-09); NPS-69Pc77091
Cold flow model tests of exhaust gas eductors with constant area mixing stacks were conducted to evaluate the effects of geometric configuration on eductor performance. Single-nozzle and four -nozzle designs were tested. ...
Unsteady surface pressure and near-wake hot-wire measurements of a circulation control airfoil.
(Monterey, California. Naval Postgraduate School, 1977-09)
The large lift coefficient changes attainable with Circulation Control Airfoils through small changes in boundary layer blowing suggest rotary wing cyclic control can be obtained through modulation of the blowing. ...
Model tests of multiple nozzle exhaust gas educator systems for gas turbine powered ships.
(Monterey, California. Naval Postgraduate School, 1977-06); NPS-69Pc77061
Cold flow model tests of multiple nozzle exhaust gas eductor systems with constant area mixing stacks were conducted to evaluate effects of geometric configuration on eductor performance. A one-dimensional analysis of a ...
Finite element solution of the nonlinear coupled neutronic-energy equations for a fast reactor fuel cell.
(Monterey, California. Naval Postgraduate School, 1976-12)
A transient overpower (TOP) accident in a Liquid Metal Fast Breeder Reactor (LMFBR) is considered. The analysis is formulated to model the dynamic response of the reactor fuel subassembly during the initial period of ...
