作者： HUMPHrEYS, dE SUMMEY, dC Dr. Douglas E. Humphreys:received his B.S. degree in Aerospace Engineering and the Ph.D. degree in Mechanical Engineering from North Carolina State University in 1966 and 1971 respectively. Between degrees he served in the U.S. Ar. my attaining the rank of Captain. From 1971 to 1980 he was employed at the Naval Coastal Systems Center (NCSC) Panama City Florida. While at NCSC he pioneered the development of techniques for predicting underwater vehicle hydrodynamic coefficients and produced a vehicle design and analysis system which integrated vehicle performance stability guidance and control. He has designed or analyzed over forty vehicles using these techniques. From 1978–1980 he was Chairman of the Naval Sea Systems Command Hydrodynamics Committee (SEAHAC). In 1981 he joined Aeronautical Research Associates of Princeton Inc. (A.R.A.P.) as Vice President of the Applied Technology Division in McLean Virginia. He is currently applying dynamics and control technology along with second-order-closure turbulence modeling techniques to the integrated design of underwater and air vehicles to minimize the deleterious effects of vehicle dynamics on mission performance especially as related to hydroacoustic signature and sensor performance. Dr. Delbert C. Summey:is presently Head of the Hydromechanics Division at the Naval Coastal Systems Center. He has been involved in R&D at the Center for the past five years developing methods for vehicle design and applying these methods to submerged and airborne naval systems. He is currently developing the HYDAT (Hydrodynamic Analysis Techniques) system of computer programs for use as a general design tool for underwater vehicles. He obtained a B.S. degree in Aerospace Engineering in 1969 from N.C. State University. As a graduate student at N.C. State he conducted research for NASA in the area of light aircraft performance stability and control. He received his Master's degree in 1971 and his Ph.D. degree in 1976 both in Mechanical Engineering.

A hydrodynamic vehicle design analysis of a towed environmental sensing system was conducted. The primary thrust of the analysis was to determine the towed vehicle geometry and mass characteristics which best meet the depth-keeping and stability requirements. The effect of the tow cable, depressor, and tow ship were also examined. The design requirements, initial vehicle geometry, the effects of geometry modifications, and the final vehicle geometry are presented. Longitudinal and lateral stability are presented as a function of geometry. Towed vehicle response is predicted for typical seaway and ship motion forcing functions, and the system tow performance is presented as a function of speed and depth.

作者： COMSTOCK, EN BALES, SL GENTILE, dM Mr. Edward N. Comstock:is currently Head of the Hull Form Design and Performance Branch (SEA 3213) of the Naval Sea Systems Command. He received his B.S.E. degree in Naval Architecture and Marine Engineering in 1970 and his M.S.E. degree in Ship Hydrodynamics in 1974 both from the University of Michigan. Mr. Comstock began his career with theU.S. Navyin 1974 as a Seakeeping Specialist in the Hull Form and Fluid Dynamics Branch of the former Naval Ship Engineering Center. Achieving his present position in January 1982 Mr. Comstock was previously Head of the Surface Ship Hydrodynamics Section of SEA 3213 being responsible for recent hull form designs including DDG-51 MCM-1 and ARS-50. Before obtaining that position in 1979 Mr. Comstock's efforts were primarily aimed at developing and establishing seakeeping performance assessment and design practices. Prior to his employment by the Navy Mr. Comstock worked in the Structural and Hydrodynamics Group of General Dynamics' Electric Boat Division. A member of ASNE he is also a member of ASE and SNAME and has been active in supporting the efforts of the SNAME H-7 (Seakeeping) Panel SNAME HS-12 (Hull Instrumentation) Panel the National Science Foundation (NSF) and the NATO Armaments Group IEG6/Sub-Group 5 (Seakeeping). Ms. Susan L. Bales:has been associated with the David W. Taylor Naval Ship R&D Center (DTNSRDC) and its predecessor organizations throughout her professional career. She is currently Head of the Ocean Environment Group of the DTNSRDC Surface Ship Dynamics Branch (1561) and also serves as the DTNSRDC Program Manager of the Navy's Exploratory Development Program on Surface Waves. Her work documented by more than fifty technical publications has been directed primarily to ship seakeeping ocean environment and ship performance assessment problems. An internationally recognized authority in her field she is also active in several professional societies as well as the SNAME H-7 (Seakeeping) Panel the National Science Foundation (NSF) and the NA

The on-going debate regarding the merits of large versus small aircraft carriers raises several issues concerning the ability of various ship configurations to support sea based air operations. One such issue is the question of the relative seakeeping performance of ship alternatives. In an effort to shed some light on the matter, a comparative seakeeping assessment of nine air capable ships covering a wide range of size and hull form was performed. An evaluation of the impact of aircraft and ship motion limitations on sea based air operations and a comparison of the relative ability of the ships to conduct air operations while in a seaway are presented. The specific air operations considered are launch, recovery, and support of aircraft. The ships evaluated are CVN-71, CVA-67 (Mr), CVV, LHA-1, VSS-d, ddV-2, ddV-1d, dd-963, and SWATH-6. These ships have the combined capability to operate Vertical Takeoff and Landing (VTOL), Conventional Takeoff and Landing (CTOL), Short Takeoff and Arrested Landing (STOAL), and Short Takeoff and Vertical Landing (STOVL) type aircraft. results indicate that seakeeping performance generally degrades with decreasing displacement, that SWATH-6 performance is the least degraded, that elevator wetness can be an important degrader for ships with lower freeboards, that roll motion can be an important degrader for ships under 60,000 tons, and that percent time of operation is strongly dependent on the prevailing wave and wind environment.

In today's environment of rapidly escalating costs, increasing technological complexity, and growing threat, we must actively seek ways to improve our effectiveness in applying limited resources to the design of Navy ships. One important aspect of this process involves the development and application of new technology to ship design. An exhaustive treatment of this subject is clearly beyond the scope of a single technical paper. It is the Authors' objective, however, to acquaint the reader with the nature and role of the Navy's Laboratory Community in general and dTNSrdC in particular; to examine some recent initiatives taken at dTNSrdC and some key issues; and, hopefully, to contribute in some small way to the building of a stronger constructive partnership between ship development and design activities. The view is that from the perspective of a Navy Laboratory and pertains to the design of the ship itself as opposed to the weapons system.

“Seakeeping … is the ability of our ships to go to sea, and Successfully and safely execute their missions despite adverse environmental factors.” — VAdm. r.E. Adamson. USN In June 1975, VAdm. r.E. Adamson, USN, then Commander Naval Surface Forces, U.S. Atlantic Fleet, addressed the participants of the Seakeeping Workshop [1] and established what has come to be a most profound definition of seakeeping as it relates to the U.S. Navy. In those few words he identified the two major issues facing the operator today and provided the focus for all subsequent seakeeping efforts within the design community at the Naval Sea Systems Command (NAVSEA). For it is these two hues of mission sum and safety at sea which are addressed within NAVSEA, for each new ship design and for ships in the Fleet, in terms of: SEAKEEPING PErFOrMANCE — Ability to execute mission in a sea environment, and SEAWOrTHINESS — Ability to survive in an extreme sea environment. In the past, the design of ships exhibiting superior seakeeping performance and seaworthiness and seaworthiness has been looked upon by many as an art or an academic exercise. The objective of this paper then is to demonstrate clearly that the ability of our ships to execute their missions successfully and safely in a sea environment is not by chance but by design.

NAVAL ENGINEErS JOUrNAL 1979年第4期91卷 51-61页

作者： WAPNEr, M THE AUTHOR graduated from the City College of the City University of New York from which he received both his Bachelor and Masters degrees in Electrical Engineering. He joined the Naval Applied Science Laboratory in 1961 where he served as Project Engineer for Ships Inertial Navigation Systems (SINS) and related equipments. Since 1967 he has been employed by the Naval Sea Systems Command (formerly NAVSHIPS) Research and Technology Directorate. initially as Navigation and Interior Communications Program Manager and currently as Director Combat Support Systems R&D Office. In addition to being the Program Manager for the Shipboard Data Multiplex System. his responsibilities include supervising research and development in areas of surveillance. fire control command and control and related command support functions. He is active in a number of U.S. Navy and foreign government information exchange programs has authored several technical papers and is a member of the Institute of Navigation and the Institute of Electrical and Electronic Engineers.

The Shipboard data Multiplex System (SdMS) is a general purpose information transfer system directed toward fulfilling the internal data Intercommunication requirements of a variety of naval combatant ships and submarines in the 1980–1990 time frame. The need for a modern data transfer system of the size and capability of SdMS has been increase in unison with the sophistication of shipboard electronic equipment and the associated magnitude of equipment-to-equipment signal traffic. Instead of the miles of unique cabling that must be specifically designed for each ship, SdMS will meet information transfer needs with general-purpose multiplex cable that will be Installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of SdMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, frees both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules and will provide ships with more advanced subsystems. This paper describes the SdMS system currently being developed by the U.S. Navy.

STOL — THE POTENTIAL OF THE CIrCULATION CONTrOL WING CONCEPT

引用

Naval Engineers Journal 1979年第2期91卷 99-108页

作者： ENGLAr, rOBErT J. The Author received his BS degree in Aerospace Engineering from Virginia Polytechnic institute and his MS degree in the same field from the University of Maryland. He has conducted the majority of the subsonic and transonic investigations of the blown airfoil sections which have led to the development of both the Circulation Control Wing and the Rotor Concepts at the David W. Taylor Naval Ship R&D Center. Having worked in the fields of both helicopter and V/STOL aircraft he is now the Program Manager on the A-6/Circulation Control Wing (CCW) Flight Demonstration Program which is primarily intended to apply this new concept in high lift technology to provide STOL capability for Navy Carrier-Based Aircraft. He also holds a number of invention disclosures related to various applications of Circulation Control Aerodynamics and is a member of the American institute of Aeronautics and Astronautics where he has published and presented several papers on the CCW Concept.

In order to develop advanced aircraft for operation from smaller air‐capable ships, research and development are being conducted at the david W. Taylor Naval Ship research and development Center to investigate the Short Takeoff and Landing (STOL) capability of the Circulation Control Wing concept. This high lift system employs tangential blowing over the rounded wing trailing edge, and can more than double the lifting capability of conventional high performance aircraft. The resulting reduced takeoff and landing speeds and distances can produce a significant favorable impact on the design of future aircraft‐carrying ships and operations from these vessels. Based on these promising benefits, a program is underway to demonstrate the STOL capability of the concept applied to a full‐scale A‐6 flight demonstrator aircraft. The present paper addresses experimental development of this vehicle, details of the full‐scale aircraft modifications, and predicted STOL performance benefits for future sea‐based aircraft so equipped. © 1979 American Society of Naval Engineers

Naval Engineers Journal 1970年第2期82卷 13-22页

作者： MUrPHY, rICHArd J. THE AUTHOR: is a graduate of Northeastern University in Boston Massachusetts where he received degrees in Mechanical Engineering and in Engineering and Managment. He is presently the Head Analyst in the Exploratory Development Division of Headquarters Naval Material Command. Since 1964 he has acted as leader of a team developing goals for exploratory development for the undersea target the air target and the land and surface target. From 1961 to 1964 he was with the Advanced Manned Missions Program Office of the NASA involved with the study of advanced launch vericle concepts for future manned orbital and manned planetary missions. Prior to this he was NASA's Headquarters Manager of the Saturn I and Saturn IB launch facilities located at the J. F. Kennedy Space Center. From 1954 to 1961 Mr. Murphy was employed by the Navy in BUSHIPS BUAIR and BUWEPS. His duties were primarily associated with R&D of non-magnetic minesweepers and new guided missile systems.

A variety of probable world political environments are postulated. From these environments, possible concepts for future warships, merchant ships, salvage ships, and research vehicles, both on the surface and undersea, are discussed. A forecast is made of the ship control systems requirements for these future ship concepts of the 21st century;and the needs for action today are highlighted. Because we can project the future best when we fully understand the past, such a history is included where suitable. Trends in ship control systems are traced up to the present time when navigation is assisted by spacecraft orbiting the earth, and these trends are projected into a future of high speed, unmanned and automated seapower. © 1970 by the American Society of Naval Engineers, Inc.
