Naval Surface Warfare Center, Carderock Division - Ship Systems Engineering Station (NSWCCD-SSES) successfully completed testing of a new Full Authority Digital Control (FADC) system for gas turbine control. This system will be back-fit onto Model 139 Ship Service Gas Turbine Generator Sets (SSGTGs) on the U.S. Navy’s Ticonderoga (CG-47) class cruisers. The FADC will be a direct replacement of the original Model 139 Local Operating Panel (LOCOP) and will control the Allison 501-K17 gas turbine. The new control system provides for standardized installation across a wide variety of existing configurations. The development program leveraged off of the design work done for the AG9140 FADC currently being installed on DDG 51 Class ships. The result was a state-of-the-art system ready for shipboard installation in a short period of time, providing commonality of look and feel across platforms. This paper describes the CG-47 FADC and details the development and testing conducted on a Model 139 SSGTG at the NSWCCD-SSES DDG 51 Gas Turbine Land Based Engineering Test Site (LBES). The test program included all modes of SSGTG operation, including starts, shutdowns, and generator operations under varying load conditions.

Development of the Northrop Grumman / Rolls-Royce WR21 Intercooled Recuperated (ICR) Gas Turbine, begun in 1992, is now well advanced and system testing has been completed on eight engine builds at the Royal Navy’s Admiralty Test House located at the Defence Evaluation and Research Agency, Pyestock in the United Kingdom. Test activity is shortly to move to the US Navy’s Test Site at the Naval Surface Warfare Center, Carderock Division – Ship Systems Engineering Station in Philadelphia, PA, where a new test facility has been built to carry out some final development testing and an endurance test. A previous paper on this subject (94-GT-186) defined a test program leading to a design review and the beginning of Qualification Testing. The development program has since evolved and it is the aim of this paper to summarize engine testing to date and set out the plan for conclusion of development testing. The paper will describe the development of the Philadelphia Test Site, as a combined site for the US Navy’s Integrated Power System (IPS) and ICR testing. This will include a description of the advanced, high-accuracy Data Acquisition System (DAS). Finally, the test program and the development and endurance test objectives will be outlined.

The U.S. Navy and Allison Engine Company successfully completed a second round of testing which integrated a new Woodward Governor Full Authority Digital Control (FADC) system for gas turbine control and a Redundant Independent Mechanical Start System (RIMSS). This integrated system will be installed on Allison Model AG9140 Ship Service Gas Turbine Generators (SSGTGs) on hull numbers DDG-86 and follow of the U.S. Navy’s Arleigh Burke (DDG-51) class destroyers. The Full Authority Digital Control (FADC) Local Operating Panel (LOCOP) will be a direct replacement of the original AG9140 LOCOP and will control both the Allison 501-K34 gas turbine and the RIMSS unit. RIMSS is a gas turbine powered, mechanically coupled start system for the SSGTGs and is designed to replace the high pressure start air system on DDG-51 class ships. This paper describes the FADC and RIMSS systems and details Phase II testing that was conducted on the AG9140 SSGTG located at the Naval Surface Warfare Center, Carderock Division - Ship Systems Engineering Station (NSWCCD-SSES) DDG-51 Land Based Engineering Site (LBES), Figure 1. The test program embodied the second portion of RIMSS testing which included the addition of the final prototype FADC control system. The test agenda included electric plant operations with the FADC and a second 500 start endurance test of RIMSS. The primary objective of Phase II testing was to evaluate the FADC control system and to further validate engine life predictions for the RIMSS engine.

As a final step of the Catalytic Combustor Development Program, a catalytic combustor developed was tested in a 150-kW gas turbine-generator unit. A digital control system was developed to improve its controllability for a transient operation, and a 200-hr continuous operation test was performed to asses the durability of the catalyst. During the test, an excellent performance of the control system was verified, and a very high combustion efficiency of more than 99% and a ultra-low NOx level of less than 5.6 ppm (at 15% O2) were achieved at a 150-kW generator output. In addition, the combustion efficiency has been maintained at over 98% for 200 hours of operation. However, the catalyst exposed to 200 hours of operation showed signs of deactivation.

U.S. Navy and Rolls -Royce Allison have conducted a fleet evaluation of the Redundant Independent Mechanical Start System (RIMSS) and Full Authority Digital Control (FADC) installed aboard USS Porter (DDG 78), No. 2 Ship Service Gas Turbine Generator (SSGTG). The fleet evaluation has resulted in design, production and operational improvements, which would not have been quickly realized under normal implementation programs. A critical objective of the fleet evaluation demonstrated the system configuration and operational compatibility with existing shipboard environments over the course of a one-year period. This process evaluated the usability of the RIMSS and FADC interface by ships force and the performance of functions related to operation and troubleshooting. It also provided feedback from Navy users for improvements. This paper describes RIMSS and FADC fleet evaluation elements and the benefits derived from performing a fleet evaluation. Fleet evaluation findings aboard USS Porter have resulted in system improvements that were achieved prior to production. Cost savings to the U.S. Navy and the original equipment manufacturer will be realized through out the life cycle of the ships.

This paper describes the qualification testing of the TF40B marine gas turbine in accordance with the duty cycle as specified in MIL-E-17341C, but with modifications that reflect the specific engine application to the U.S. Navy LCAC vehicle. Among the particular requirements of the 1000 hour test are continuous operation in a salt-laden environment of given concentration and humidity, and frequent shutdowns from relatively high power with an ensuing soakback interval. The narrative discusses the method of test, the duty cycle, and the results which were obtained. In an epilogue which focuses on posttest activities, a description is given of the corrective actions taken to resolve certain problems that arose during the course of the test. One such problem, namely the occurrence of carbon erosion upon certain hot section components, was eliminated by modification to the combustor, in a very successful posttest test development program.

The U.S. Navy has experienced problems with liquid fuel nozzles used on the Rolls Royce (formerly Allison) 501K series marine gas turbine engines. The 501K engines used by the U.S. Navy power Ship Service Gas Turbine Generators (SSGTGs) on a number of destroyer and cruiser class ships. Over roughly the last 25 years, 3 different nozzle designs have been employed, the latest and current nozzle being a piloted air blast design. The primary failure modes of these designs were internal fuel passage coking and external carbon deposits. The current piloted air blast design has a hard time replacement requirement of 1500 hours. This life is considered unacceptable. To improve fuel nozzle life, the Navy and Turbine Fuel Technologies (formerly Delavan) teamed in a fast track program to develop a new fuel nozzle with a target life of 5000 hours and 500 starts. As a result, an air assist/air blast nozzle was developed and delivered in approximately 6 months. In addition to the nozzle itself, a system was developed to provide assist air to the fuel nozzles to help atomize the fuel for better ignition. Nozzle sets and air assist systems have been delivered and tested at the NSWC Philadelphia LBES (Land Based Engineering Site). In addition, nozzle sets have been installed aboard operating ships for in-service evaluations. During the Phase one evaluation (July 2000 to June 2001) aboard USS Porter (DDG 78) a set of nozzles accumulated over 3500 hours of trouble free operation, indicating the target of 5000 hours is achievable. As of this writing these nozzles have in excess of 5700 hours. The improvements in nozzle life provided by the new fuel nozzle design will result in cost savings through out the life cycle of the GTGS. In fact, the evaluation nozzles are already improving engine operation and reliability even before the nozzles’ official fleet introduction. This paper describes the fuel nozzle and air assist system development program and results of OEM, LBES and fleet testing.

Allison has developed both an engine and a ship service gas turbine generator set (SSGTG) for use in the U.S. Navy DDG-51 destroyer program. The engine is the Model 501-K34, which uses the technology of the new generation of Allison 501 engines. The generator set is the Model AG9130, a totally self-contained package powered by the Model 501-K34. The design concepts and resulting design for the engine and generator set are provided, as well as an overview of the performance characteristics. The ship’s electrical system is discussed, and the role of the generator set in that system is defined. The design features of the generator set are given with further discussion of the main components (the engine, speed reduction gearbox, generator, base and enclosure) and the mechanical support systems for these components (the gas turbine lube oil system, reduction gear/generator lube oil system, fuel system, seawater cooling system, starting system, bleed air system, cooling air system, fire protection system, water wash and icing detection system, and the electrical system). A review of the testing for both the engine and the SSGTG at Allison Gas Turbine and the Naval Ship Systems Engineering Station is presented. Installation and integration of the SSGTG into the ship closes the discussion.
