Matching Engine and Propeller
(University of Michigan, 1973-06-01)
The torque and shaft speed (rpm) of an engine will be the same as the torque and rpm of the propeller it drives. The marine designer attempts to place this torque_rpm coincidence at a point that will be best by some criterion ...
Loading of the Hull Girder
(University of Michigan, 1971-12-01)
Current progress in ship structure analysis is extremely rapid. Until the middle of the 1950's, all computations of external longitudinal stresses in ships were done using the quasistatic method which is discussed in section ...
Measures of Merit for Ship Design
(University of Michigan, 1977-07-01)
My purpose in writing this paper is to explain the role of engineering economy in ship design and to discuss the relative virtues and shortcomings of the several measures of merit in current use. In particular, I want to ...
Maneuverability in Restricted Waters: State of the Art
(University of Michigan, 1976-08-01)
An overview of restricted_water maneuvering with heavy emphasis on the course stability of ships in canals is presented, starting with the underlying linear equations and proceeding to the theoretical prediction of the ...
Note on the modified two-stream approximation of sagan and pollack
(Elsevier, 1973-06)
The modified two-stream approximation is derived from the radiative transfer equation using a two-point gaussian quadrature and neglecting terms of order l [ges] 3 in the Legendre expansion of the phase function. The results ...
Maritime Prospects in Northwestern South America
(University of Michigan, 1972-07-01)
This report summarizes a study of the maritime details of the northern Pacific coast of South America. The ports and national fleets of Colombia, Ecuador, and Peru are tabulated to summarize the data relevant to preliminary ...
Forward Speed Effects on the Sway, Roll, and Yaw Motion Coefficients
(University of Michigan, 1978-11-01)
The added mass and damping coefficients for sway, roll and yaw are formulated for a ship with forward speed. The theory is similar to that given by Ogilvie and Tuck (1969) for the heave and pitch coefficients of a slender ...
