This paper discusses the Interactive Graphics System used by the General Electric Company, Medium Steam Turbine Department (engineering & Manufacturing) for designing, drafting, and manufacturing applications. A brief overview of the hardware malting up the system is described, followed by a more detailed description of the actual applications. Two-dimensional applications described include a Heat Balance Analysis, Flow Diagrams, and Electrical Schematics. A more fruitful area for increased productivity gains is described in the three-dimensional or mechanical applications including turbine design & layout and bucket design. coordination of the design with manufacturing for numerical control tape generation is described through CAM and Plate Frame Cutting applications. Finally, a short review of the engineering design work using Interactive Graphics is discussed. Productivity gains of 2.6 to 1 are being realized, and the overall savings to the Medium Steam Department are outlined.

Currently he is the Director Comparative Naval Architecture Program in the Naval Sea Systems Command. Capt. Kehoe has been a member of ASNE since 1974 and has authored two technical papers on U.S. and Soviet ship design practices which were published in theU.S. Naval Institute Proceedingsand theNaval Engineers Journal. Cdr. Clark Graham
USNbetter known as “Corky.” graduated from the U.S. Naval Academy in 1964 and subsequently received his Ph. D. degree from Massachusetts Institute of Technology (MIT) in 1969. Currently. he is assigned to the Naval Sea Systems Command as the DDGX Ship Design Manager. Previous to this assignment. he was the NAVSEA Cruiser Project Manager Representative and SUPSHIP Newport News Project Officer for Nuclear Cruisers. He has served in three combatant ships including the Guided Missile CruiserUSS Gridley (CG-21)as Engineer Officer.

This paper is a report of a comparative naval architecture analysis of United States, Canadian, French, Netherlands, German, British, and Soviet Frigates. The investigation covered general arrangements, weapons and sensors, survivability, intact and damaged stability, manning and personnel support (all of which me discussed in PART I), and hull form, propulsion, speed range, sea keeping, ship size, and future growth capability (to be published in PART II). Weapons and sensors were only addressed in terms of their impact on the weight and volume of the ship. The actual military effectiveness of each Frigate was not assessed.

Since the signing of the Contract Design Plane for the CVN 68 (the U.S. Navy's latest Class of Aircraft Carriers) In 1963, considerable technological advances have been made in Naval Ship Design. This paper provides specific examples of how new technology has affected traditional Carrier design practices and techniques, and also indicates areas where future advanced technology will be needed. It is divided into four sections: 1) Computer Design Application; 2) Total Ship Energy Conservation Analysis; 3) Advances in Structural Design; and 4) Impact of V/STOL Aircraft. The increased use of the computer to define ship characteristics in the initial stage of ship design is discussed, followed by a report on efforts to include energy conservation as an integral part of the design process. The energy conservation approach uses traditional analytical techniques to develop innovative design configurations that will achieve energy savings. Of the many advances in Carrier structural design, two specific examples are given: 1) Elimination of the infamous “knee-knockers” (high sills in passageway openings) common to Gallery Deck structure, and 2) Successful attempts at reducing the thickness of aircraft elevator platforms. The paper concludes by pointing out some possible challenges facing the ship designer and some of the technology already created by the expected introduction of advanced design Vertical/Short Takeoff and Landing (V/STOL) aircraft.
This paper reviews the recent turbulent history of the U.S. Shipbuilding Industry, its present status, and its prospects for the decade ahead. The Authors suggest that current maritime policy and the trend of market f...

The MK 92 Fire Control System (FCS) & a new, integrated, highly reliable and light-weight U.S. Navy Fire Control System for missile and gun control. This system, which is in production for the FFG, PCG, PGG and PHM Ship Classes, provides the detection and automation required for modern naval warfare. Search radar data & presented at a very high rate at the operator's console, a highly integrated man-machine interface. Utilization of monopulse and “track-while-scan” techniques result in multiple target tracking capability. The system console(s) offer a self-contained command and control capability and, in addition, standard digital computer channels provide the versatile interface with the ship's command and control, integrating the complete engagement process. Error cancellation techniques are employed to obtain high performance accuracy even under severe environmental conditions. The low manning requirement for both operation and maintenance is a key system attribute for all applications. Comprehensive “at-sea” evaluations, performed by the U.S. Navy, demonstrated successful system operation in all modes of surveillance, multi-target tracking and simultaneous missile and gun engagements. The “at-sea” performance record of the FCS MK 92 was cited by the Chief of Naval Operations to have established new standards for Naval Surface Weapons systems.

MORISSEAU, KCThe author graduated from the New York State Maritime College in 1956
receiving his BS degree in Marine Engineering. He then reported to the Navy's Bureau of Ships where after 18 months training he was assigned to the Hull Mechanical Section in the Hull Design Branch. During this period he was involved in the contract design of various materials handling features of naval ships including vehicle and cargo handling for Amphibious Ships electronics equipment handling and replenishment at sea and in addition also was charged with the management and operation of the Division's computer installation. In 1964 he became the Hull Project Coordinator for the AOR 1 Class AO(J) 51 Class and the AOE 3 Class ships and after completing their contract design was transferred to the Auxiliary Type Desk and reassigned as AE 26 Class Project Engineer. From 1965 until 1974 he was the Program Manager for the FAST System and the Missile/Cargo STREAM System in the Underway Replenishment Project Office (PMS–390)/Underway Replenishment Division (SHIPS–490) and its organizational predecessors. In April 1974 when SHIPS–490 and SHIPS–427 were merged he became Head of the Underway Replenishment Improvement Branch the position he now holds in the Naval Sea Systems Command.
Late in 1970, Admiral E. R. Zumwalt, Chief of Naval Operations, directed that study begin towards development of a new class of ocean escort, now known as the FFG 7 (Oliver Hazard Perry) Class, to take over some of th...
