One of the most serious problems encountered in Naval steam plants following World War II was the unreliable performance of boiler and main feedpump pneumatic control systems. In addition to control component and system design deficiencies, these control systems suffered from inadequate methods to measure and adjust system alignment. This paper describes the development of a set of procedures for on-line alignment verification (OLV) of pneumatic main boiler and feedpump control systems. The procedures are designed for use by N avy control system technicians and, in addition to on-line alignment verification, provide guidance for troubleshooting and for performing system alignment. Procedure static checks measure steady state steaming performance and OLV procedure dynamic checks measure the ability of the boiler and control systems to respond to load changes. The paper describes typical control system characteristics that influence OLV procedure content and the supporting analysis that was used to establish alignment criteria ranges that satisfy both steady state and transient performance requirements. Also described is the alignment criteria tolerance analysis along with the steps involved in a typical OLV check procedure development. Descriptions of the various OLV checks, troubleshooting procedures and alignment procedures are provided. Typical shipboard implementation requirements are described and experience to date with the procedures is provided along with a status report on OLV procedure implementations.

The machinery arrangement design process has remained relatively unchanged over the years. Recently, external demands have been placed on both the product and the producers that call for changes to this process. This paper cites these external demands and traces the evolution of the process changes from the rule-of-thumb machinery box sizing routines up to the current automated procedures. The machinery arrangement design practice is presented, and existing analytic and graphics aids are discussed. The user requirements for improved design aids are presented, with implementation guidelines and hardware/software alternatives.

CAMPBELL, JSTHE AUTHOR was born in Porterville. Calif.
in 1928 and joined the U.S. Nary in 1945 in the “Aviation Midshipman” Program. He received his designation as a Naval Aviator in 1950 and flew combat missions in Korea while still a Midshipman followed by participation in various operational and training squadrons until 1958 when he completed the Naval Test Pilot School Program. After a tour as an Engineering Test Pilot. he attended the Naval Postgraduate School Monterey. Calif. and was then assigned to the Fleet Computer Programming Center as a part of the NTDS development. Later he had operational tours as CIC Officer in the USS Enterprise and as AAW Officer on the Staff of Commander Task Force SEVENTY-SEVEN in Vietnam. During an interceding tour of duty he was the Program Manager for the TACDEW Training Facilities at San Diego Calif: and Dam Neck Va. After completing his active duty in the U.S. Navy Mr. Campbell joined Logicon Inc. and during the six years with the Tactical and Training Systems Division held various positions including Project Manager Department Head Assistant Director and Division Director prior to leaving in 1976 to join the Assistant Secretary of the Nary for R&D as Special Assistant for Weapons Systems Integration. In 1978 he joined the Staff at the Naval Ocean Systems Center as Associate Director for Command Control and Communications and Acting Head of the C3I Systems Department where he is charged with the development and operation of the C3Systems Integration Test and Evaluation Laboratory.

The increasingly important role of land-based test sites (LBTSs) in military command, control, and communications (C 3 ) is discussed, with particular reference to system integration, R&D, and testing. The LBTS at the Naval Ocean Systems Center (NOSC), San Diego, is described in detail, and lessons learned from the operation of the and other LBTSe are considered in terms of both their tactical and strategic implications.

This paper presents an integrated approach to computer-Aided Ship Design for U.S. Navy preliminary and contract design. An integrated Hull Design System (HDS), currently under development by the Hull Group of the Naval Sea Systems Command (NAVSEA 32). is the vehicle for the discussion. This paper is directed toward practicing ship design professionals and the managers of the ship design process. Primary emphasis of this paper, and of the development effort currently under way, is on aiding ship design professionals in their work. Focus is on integration and management control of the extremely complex set of processes which make up naval ship design. The terminology of the Ship Designer and Design Manager is used. The reader needs no familiarity with the technologies of computer science.

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.
