SNAME Spring Meeting (Continued from page 10)

Paper No. 4—"Fishing Vessel

Development" by D.J. Doust. The paper describes the development of fishing vessels over the past 15 years, including the transition from side to stern trawling. Various de- signs evolved during this period are discussed.

Paper No. 5—"The Construction assistance Vehicle (CAV), An Un- derwater Pickup Truck" by S. Hal- pern and S.A. Black. The construc- tion assistance vehicle is a free- flooding, electro-hydraulically pow- ered "wet" submersible. It is an ex- perimental craft designed to pro- vide free-swimming scuba divers with an "underwater pickup truck" capable of delivering up to 2,000 pounds of wet-weight cargo.

Paper No. 6. — "An Underwa- ter Buoyancy Transport Vehicle (BTV)" by N.B. Estabrook and

A.T. Strickland. This paper de- scribes the development of the

Buoyancy Transport Vehicle, a diver-operated undersea vehicle ca- pable of lifting and transporting loads up to 1,000 pounds at ocean depths to 850 feet. This underwater "fork-lift" was designed and built to alleviate many of the difficulties experienced by working divers.

Paper No. 7—"Propulsion and

Maneuvering Systems for Deep

Submersibles" by R.W. Peach and

F.C. Munchmeyer. This paper re- lates to propulsion, maneuvering, trimming and 'ballasting systems

Presenting Paper No. 1 2 were, left to right: presiding officer Monroe D. Macpherson,

Esso International Inc.; author R.F. Jones

Jr., Structural Materials Branch, Naval

Ship Research and Development Center, and assisting presiding officer Frank H.

Porter, chief nuclear engineer, Nuclear

Power, Div. Pearl Harbor Naval Shipyard. for deep submersibles. It describes the purpose of these systems and the characteristics of those used on a range of submersibles.

Paper No. 8—"Analysis of Jet

Propulsion for Deep Submergence

Vessels: Ideal Fluid Analysis and

Boundary-Layer Control" by T.P.

Torda and D.W. Kos. Analytical work is presented on flow control by suction and blowing as it ap- plies to submerged vessels. Drag reduction and increase of overall efficiency are aims of the analytical work.

Paper No. 9—"Lightweight Syn- tactic Foam as Buoyancy Material for a 20,000-Foot Deep-Sea Vehi- cle" by H. Bernstein and M. Kren- zke. Present investigations of syn- tactic foam (hollow glass micro- spheres dispersed in a resin ma- trix) are the result of extensive tradeoff studies of candidate buoy- ancy systems for a small manned vehicle capable of operating to ocean depths of 20,000 feet. Suc- cessful completion of this develop- ment will improve the performance of deep-sea vehicles.

Paper No. 10—"Rapid Analysis of Marine Structures" by P.Y.

Chang and W.D. Pilkey. The line- solution technique for the static, stability, and dynamic analysis of an array of marine structures is de- scribed. This approach differs from the classical techniques of stiffness and flexibility in the efficiency of the method used in eliminating un- knowns.

Paper No. 11—"The Design of

Thick-Walled Unstiffened Cylin- ders Subjected to Uniform Exter- nal Pressure" by S.R. Heller Jr.

The available technical literature dealing with the biaxial and triaxial stress in closed, unstiffened cylin- der under uniform pressure is eval- uated. Also included are sets of curves to ease the numerical work of design.

Paper No. 12—"Structural Anal- ysis of Deep Submergence Pres- sure Hulls" by L.N. Gifford Jr. and

R.F. Jones Jr. This paper discusses the application of the finite-element method of structural analysis to the analysis of present and future deep submersible vehicles. Examples are given of the automated graphical display of computed results.

Presenting Paper No. 4 were, left to right: discussor Capt. R.T. Miller, presiding offi- cer Lester Rosenblatt, president, M. Rosen- blatt & Son, Inc. who read the paper, and assisting presiding officer G.W. Slaughter,

Pearl Harbor Naval Shipyard.

Research Institute, Chicago, III., and Prof.

Richard B. Couch, presiding officer, Dept. of Naval Architecture, U. of Mich.

Office of Ship Construction, Maritime Ad- ministration; author S.R. Heller Jr., pro- fessor of mechanical engineering, The

Catholic University of America, and Rear

Adm. T.J. Fabik, USCG (ret.), assisting presiding officer.

Ventures, Inc., and presiding officer Richard Broad, Newport News Shipbuilding and

Dry Dock Company.
