This paper discusses the data that were recorded during a three-month accelerated humidity test of two Tomahawk all-up rounds (AURs), one pressurized with dry nitrogen in accordance with the current practice, and the other left unpressurized. Temperature and humidity were recorded inside the canisters and missiles. Data analysis consisted of psychrometric calculations to determine the moisture intrusion into these missiles during the test. The work was carried out in support of a technical effort directed at changing the storage and stowage environmental protection of the Tomahawk missile.

RATIONALE FOR AN ADA SOFTWARE engineering ENVIRONMENT FOR NAVY MISSION CRITICAL APPLICATIONS

引用

NAVAL ENGINEERS JOURNAL 1984年第4期96卷 133-145页

作者： PAIGE, KK CONVERSE, RA USN LCdr. Kathleen K. Paige USN:graduated with a BA from the University of New Hampshire in 1970. She received her commission from Officer Candidate School in April 1971 and performed her first tour of duty with VFP-63 NAS Miramar. LCdr. Paige then received her MS from the Naval Post Graduate School in June 1976 and returned to San Diego to serve as Head Support Software Division at the Fleet Combat Direction System Support Activity. In May 1981 she reported to NA VSEA (PMS-408) where she served initially as Chairman of the NAVMAT Software Engineering Environment Working Group. She has been assigned as Deputy AN/UYK-43 Acquisition Manager since October 1981. LCdr. Paige was designated a fully qualified Engineering Duty Officer in December 1983. Robert A. Converse:is presently the Acquisition Manager for the Ada Language System/Navy (ALS/N) for the Naval Sea Systems Command Tactical Embedded Computer Resources Project. As such he is responsible for the definition and development of the ALS/N to be provided as a Navy standard computer programming system for Navy mission critical applications. Mr. Converse received a Bachelor of Science degree in Physics from Wheaton College Wheaton II. He spent fourteen years with the Naval Underwater Systems Center Newport Rhode Island during which time he designed and developed the Fortran compiler for the Navy Standard AN/UYK-7 computer. Also during that period he received a Master of Science degree in Computer Science from the University of Rhode Island. His thesis for that degree was entitled “Optimization Techniques for the NUSC Fortran Cross-Compiler”. Mr. Converse started his involvement with the Ada program in 1975 with the initial “Strawman” requirements review. Subsequently he was named as the Navy Ada Distinguished Reviewer and was intimately involved in the selection and refinement of the Ada language as it evolved to become ANSI/MIL-STD-1815A.

The U.S. Navy introduced the use of digital computers in mission critical applications over a quarter of a century ago. Today, virtually every system in the current and planned Navy inventory makes extensive use of computer technology. Computers embedded in mission critical Navy systems are integral to our strategic and tactical defense capabilities. Thus, the military power of the U.S. Navy is inextricably tied to the use of programmable digital computers. The computer program is the essential element that embodies the system “intelligence”. In addition, it provides the flexibility to respond to changing threats and requirements. However, this very flexibility and capability poses a host of difficulties hindering full realization of the advantages. This paper describes the lessons learned about computer program development over the past twenty five years and discusses a software engineering process that addresses these lessons. It then describes how Ada and its related Ada programming Support and Run-Time Environments foster this software engineering process to improve computer program productivity and achieve greater system reliability and adaptibility. Finally, the paper discusses how the use of Ada and its environments can enhance the interoperability and transferability of computer programs among Navy projects and significantly reduce overall life cycle costs for Navy mission critical computer programs.

Bindar 1Nuclear Physics and Biophysics Institut Teknologi Bandung Bandung 40132 Indonesia 2Master Program in Physics Institut Teknologi Bandung Bandung 40132 Indonesia 3Nanotechnology and Graphene Research Center Universitas Padjadjaran Sumedang 45363 Indonesia 4Theoretical High Energy Physics Institut Teknologi Bandung Bandung 40132 Indonesia 5Physics of Earth and Complex Systems Institut Teknologi Bandung Bandung 40132 Indonesia 6Energy and Processing System of Chemical Engineering Institut Teknologi Bandung Bandung 40132 Indonesia

Binding force in the form of spring force binds two adjacent spherical grains and based on this interaction various structures of composite particles can be constructed. In this work only composite particles up to N = 4 are discussed, where N is number of spherical grains in a composite particle, and the forms are limited to the two-dimensional cases only. There is only one structure of composite particle for each value of N for 1 < N ≤ 2. For N = 3 there are five structures and for N = 4 there are fifteen structures. Between spherical grains from different composite particles only two types of force are considered. The first is a long-range attractive force in the form of gravitation force and the last is a short-range repulsion force in the form of normal force. The first type of force will help the aggregation process, while the second will prevent two spherical grains to collapse into a single grain due to the first. It is observed that the time required to produce the compact aggregate or T is dependent on N, where larger N makes larger T.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

He is a registered professional engineer in the District of Columbia and has written several technical papers on waste heat recovery and energy conservation. Jeffrey Fleming:is a senior project engineer in the Energy R&D Office at the David Taylor Naval Ship R&D Center. In his current position as group leader for the future fleet energy conservation portion of the Navy's energy R&D program he is responsible for the identification and development of advanced components and subsystems which will lead to reductions in the fossil fuel consumption of future ships. Over the past several years he has also directed the development and application of total energy computer analysis techniques for the assessment of conventional and advanced shipboard machinery concepts. Mr. Fleming is a 1971 graduate electrical engineer of Virginia Polytechnic Institute and received his MS in electrical engineering from Johns Hopkins University in 1975. Mr. Fleming has authored various technical publications and was the recipient of the Severn Technical Society's “Best Technical Paper of the Year” award in 1

In support of the Navy's efforts to improve the energy usage of future ships and thereby to reduce fleet operating costs, a large scale computer model has been developed by the David Taylor Naval Ship Research and Development Center (DTNSRDC) to analyze the performance of shipboard energy systems for applications other than nuclear or oil-fired steam propulsion plants. This paper discusses the applications and utility of this computer program as a performance analysis tool for design of ship machinery systems. The program is a simulation model that performs a complete thermodynamic analysis of a user-specified energy system. It offers considerable flexibility in analyzing a variety of propulsion, electrical, and auxiliary plant configurations through a component building block structure. Component subroutines that model the performance of shipboard equipment such as engines, boilers, generators, and compressors are available from the program library. Component subroutines are selected and linked in the program to model the desired machinery plant functional configurations. The operation of the defined shipboard energy system may then be simulated over a user-specified scenario of temperature, time, and load profiles. The program output furnishes information on component operating characteristics and fuel demands, which allows evaluation of the total system performance.

作者： COLEMAN, JAMES J. USN The author is a graduate of the U.S. Navy Academy Class of 1957. Prior to pursuing an advanced degree at Webb Institute of Naval Architecture he spent two years in destroyers and four years in submarines. Designated an Engineering Duty Officer (EDO) in 1966 he attended the Deep Sea Diving School and proceeded to Hunters Point Division of the San Francisco Naval Shipyard. Here he was responsible for the production efforts in the Deep Dive System MK 2 and the SEALAB III Program. While at Hunters Point he was also the 12th Naval District Salvage Officer and the Salvage Master during the raising of the nuclear submarine USS Guitarro which sank at Mare Island Naval Shipyard in May 1969. Following a tour on the Staff Commander Service Force U.S. Atlantic Fleet as the Fleet Salvage Officer he assumed command of the Experimental Diving Unit Washington D.C. in 1971 with additional duty at the Naval Ship Systems Command as the Supervisor of Diving. During this tour the Experimental Diving Unit conducted a world record 1600 foot wet hyperbaric dive. Relieved of this command on 1 October 1973 he presently remains as the Supervisor of Diving.

The office of the Supervisor of Diving, Naval Ship systems Command, is responsible for the development and testing of swimmer and diver equipment. The goal of the Navy Diving program is to enable the diver to work safely, efficiently, and in comfort at 1,000 feet today;1,500 feet in the near future;and 2,500 feet in the far term. This program is divided into three areas of concern: a) Surface Supported Diving;b) Integrated Diving system;and c) Man‐in‐the‐Sea Deep Ocean. The paper focuses on the aforementioned areas by relating to existing equipments, their problems, and what programs are currently being proved to resolve these problems. © 1974 American Society of Naval Engineers
