SIMPLIFICATION OF GAS-TURBINE INTAKE ANTI-ICE SYSTEMS

NAVAL ENGINEERS JOURNAL 1988年第1期100卷 45-52页

作者： EXELL, JR KILLINGER, A LCdr. John R. Excell: USN received a bachelor of architecture from the University of Michigan and a master of science degree in mechanical engineering from the U. S. Navy Postgraduate School. He was commissioned in 1973 serving first as damage control assistant aboard USSGuadalcanal(LPH-7) and later as commissioning main propulsion assistant on USSMerrill(DD-976). He became an engineering duty officer in 1979 and served at Norfolk Naval Shipyard as senior ship superintendent for six ships and later within the shipyard Design Department. In May 1984 LCdr. Exell was assigned to the DD-963 Class Special Projects Office as program manager for air system improvements including the bleed air and anti-ice systems. He recently completed the Defense Systems Management College Ft. Belvoir VA and returned to NavSea PMS 377 as deputy for strategic sealift programs. Arthur Killinger:graduated from the University of Maryland in 1968 with a bachelor of science degree in mechanical engineering. He joined MPR Associates Inc. working on submarine safety design reviews following the loss of USSScorpion(SSN 589). After two years in the U.S. Army Nuclear Reactor Program and a year as U.S. Army engineer maintenance advisor in the Republic of Vietnam he returned to MPR Associates Inc. in 1972. Since then he has worked on nuclear power plant projects for several electric utilities as well as submarine and surface ship overhaul and maintenance improvement programs for the U.S. Navy. Mr. Killinger is a member of the American Society of Naval Engineers and the American Society of Mechanical Engineers.

This paper describes the steps taken to simplify the gas turbine intake anti-ice systems on DD-963 and DDG-993 class ships. The anti-ice system was designed and built as fully-automatic protection against intake duct icing on main propulsion turbines and electric generator turbines. Operating experience with the system indicated that it was nonfunctional more than 60% of the time. The system's poor availability was caused by its complexity, lack of use, lack of spare parts, poor training and documentation, and design and material problems. A Navy Independent Design Review Team (IDRT) reexamined the technical bases for installing an automatic anti-ice system and demonstrated that automatic control was not necessary for gas turbine intake duct anti-icing. A series of design review calculations and shipboard tests confirmed that anti-icing protection could be provided by manual control of installed butterfly valves feeding hot air to each turbine intake. The time from the IDRT design simplification recommendations to the first modification of the anti-ice system was less than one year. To date, half of the 30 of the 35 ships in the two classes have been modified. This system simplification will result in life cycle maintenance cost savings in excess of 13 million dollars. Future CG-47 class and DDG-51 class ships will include this simplified approach to anti-ice system design for gas turbine intakes.

Some fairly radical changes to the naval ship design process occurred during the 1970s. The decade of the 80s has also witnessed a steady stream of changes. One of the most significant was the establishment of the Ship Characteristics Improvement Board (SCIB) in the Office of the Chief of Naval Operations (OpNav), and the resulting influence on the dialog between the military requirements decision makers and the Navy's ship designers. Other changes have occurred for which the impacts are less clear. These include establishment of the chief engineer of the Navy (ChEng) position, creation of the Space and Naval Warfare Systems Command (SpaWar) and OpNav's “Revolution at Sea” initiative. This paper will describe and discuss these and other changes, and comment on the resultant impact. The authors will attempt to present a global view of the total pattern of changes and try to discern if we are on a path of revolution, or merely normal evolution.

Due to demographical factors, there will be a 25% decline in the national labor pool of eligible 17 to 21 year old men by 1992. As the Navy faces fierce competition with other services and private industry for the dwindling personnel resources of the nation, efforts must be made to consider automating certain tasks, especially those that are hazardous, boring, and labor intensive onboard ships at sea. The Surface Ship Continuing Concept Formulation (CONFORM) Program (SEA-5014) sponsored the Naval Surface Weapons Center's Robotics Laboratory to identify potential applications of robotic and artificial intelligence systems to operation and mission activities for shipboard use. The results of the investigation concerning applications of robotics to automate the aforementioned tasks are presented. Changes in current manning levels for selected tasks and ship classes, i.e., CVs, CVNs, LPDs, LPNs, and auxiliaries are examined. Future ship designs incorporating robotics, such as the advance based repair (ABR) ship are discussed. Twenty-four applications were cited in the study which include a remote controlled vehicle for flight deck operations, limited tasks in biological, chemical, and radiation environments, computer aided command decision aids, ordnance handling, undersea search, recovery, and salvage, and ventilation duct cleaning. Four of the applications and their subsequent hardware fruition will be discussed.

This paper describes a computer integrated engineering system for design and life cycle management of weapons systems, ships and other multidisciplined systems. All engineering data are stored in a central engineering database. Individual application databases define and process information necessary for specific discipline evaluations. Interface modules between the application databases and the engineering database ensure that the entered data are complete, consistent, compatible, and in compliance with requirements. Conflicts are immediately identified and efficiently resolved. Implementation of the system improves design quality and reduces costs by minimizing the number of design iterations, reducing the effort to implement changes, providing effective storage and retrieval, and reducing the need for ship checks prior to modifications and alterations.

Ship's propellers are currently measured by manual procedures using pitchometers, templates and gauges. This measurement process is extremely tedious, labor intensive and time consuming. In an effort to provide increased accuracy, repeatability and cost effectiveness in propeller manufacture, an automated propeller optical measurement system (APOMS) has been built which rapidly and automatically scans an entire ship's propeller using a 3-D vision sensor. This equipment is integrated with a propeller robotic automated templating system (PRATS) and the propeller optical finishing system (PROFS) which robotically template and grind the propeller to its final shape, using the APOMS-derived data for control feedback. The optical scanning and the final shape are both controlled by CAD/CAM data files describing the desired propeller shape. An automated propeller balancing system is incorporated into the PROFS equipment. The APOMS/PRATS/PROFS equipment is expected to provide lower propeller manufacturing costs.

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.
