The Redundant Independent Mechanical Start System (RIMSS) is a gas turbine powered, mechanically coupled start system for the Allison AG9140 Ship Service Gas Turbine Generator Sets (SSGTGs) of the U.S. Navy’s DDG-51 Class ships. The system will be original equipment on DDG-86 and follow. It will also be a candidate for backfit onto earlier DDG-51 Class ships. This paper describes RIMSS and details a very successful phase of the RIMSS program. All U.S. Navy testing was conducted on an Allison AG9140 located at the Carderock Division, Naval Surface Warfare Center-Ship Systems Engineering Station, DDG-51 Gas Turbine Ship Land Based Engineering Site (NSWCCD-SSES LBES), Figure 1. The test agenda included 516 SSGTG starts and 75 SSGTG motoring cycles. The primary goal was to validate engine life predictions for the Allison 250-C20B gas turbine engine in the RIMSS application. A secondary goal was to evaluate the overall RIMSS system during an extended period of operation.

The Ship Service Gas Turbine Generator sets (SSGTGs) on the U.S. Navy’s DDG-51 Class ships have experienced several gas turbine engine failures resulting from seawater contamination of the lube oil. The seawater enters the turbine lube oil system after a corrosion related failure of the lube oil cooler. This paper examines the system design, failure mechanism, and consequence of the failure. It also discusses maintenance actions intended to minimize the possibility of cooler failures, methods that have been used to clean up contaminated systems and alternate cooler designs that are being considered for backfit.

Auxiliary power is often provided on combat vehicles in the U.S. Army for battery charging, operation of auxiliary vehicle equipment when the main engine is not running, or to provide assistance in starting the main engine in extreme cold weather conditions. The use of a gas turbine for these applications is particularly attractive, due to its small size and lightweight. In November 1978, the U.S. Army Tank-Automotive Research and Development Command, Warren, MI awarded a contract to the Turbomach Division of Solar Turbines International, San Diego, CA, for the development of a 10 kW 28 vdc gas turbine powered auxiliary power unit (APU) for installation in the XM1 main battle tank. This paper describes the general features of the Solar Turbomach T-20G-8 Auxiliary Power Unit, a single-shaft gas turbine driven generator set which has been developed under this contract. This APU is one of the family of Gemini powered APUs and is a derivative of the U.S. Army 10 kW gas turbine engine-driven, 60 and 400 Hz generator sets developed by Solar. The electrical components were newly developed for this particular application. Currently, the APU is in qualification testing both in the laboratory and in the XM1 main battle tank.

Operational availability of Gas Turbine Generator Sets (GTGs) aboard the U.S. Navy’s DDG 51 Class ships is being enhanced through the combined capabilities of the ship’s Integrated Condition Assessment System (ICAS) and the GTG’s Full Authority Digital Control (FADC). This paper describes the ICAS and FADC systems; their current capabilities and the vision of how those capabilities will evolve in order to improve equipment readiness and reduce life cycle costs.

A salt ingestion test was performed on the AGT 1500 recuperated automotive gas turbine engine at the Naval Ship Systems Engineering Station (NAVSSES) for the U.S. Marine Corps. The Marine Corps was concerned about the AGT 1500’s ability to tolerate their amphibious and maritime environments. The AGT 1500 was operated for two 450 hour endurance runs burning Navy diesel fuel and ingesting aerosol salt. It suffered no failures or significant loss of power as a result of the ingested salt or operations with Navy diesel fuel.

The Rolls-Royce Allison (RRA) 501-K34 serves as the prime mover for the Ship Service Gas Turbine Generator sets (SSGTGs) of the U.S. Navy’s DDG-51 Class ships. Navy experience with the 501-K34 began in 1988 with the testing of the first prototype. Experience to date includes over 700,000 fired hours on a growing fleet of engines. This paper explores that operating experience and discusses future plans to improve the engine’s operational availability while lowering life cycle costs.

This paper looks back at the evolution of the Gas Turbine Generator sets (GTGs) in the U.S. Navy’s DDG 51 Class, reviewing lessons learned, successes and areas where work is still required. Topics are discussed in the context of Mean Time Between Failure (MTBF) Total Ownership Cost (TOC) and maintainability. It reviews changes that resulted in MTBF increasing by a factor of five and TOC dropping by a factor of four. It also looks to the future, identifying potential areas of further improvement.

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.

Most gas turbine generators rely on an automatic-engaging, free-wheel clutch to connect a starting motor to accelerate the gas turbine generator from zero to some intermediate speed to enable ignition and then provide torque assistance to a higher speed until the gas turbine is self-sustaining. The U.S. Navy has used various designs of starter motors and clutches for its gas turbine fleet. In addition, there has been a requirement to periodically borescope each gas turbine, which has necessitated removal of the starting system and clutch assembly in each instance. This paper examines the U.S. Navy experience with starting clutches and provides details of the development and testing of a synchronous-self-shifting clutch with an additional, stationary, manual turning feature to provide very slow and precise gas turbine rotor rotation for borescope purposes. This paper also gives details of the installation of the first two prototype clutches on the USS Ramage, DDG 61, operating experience for approximately four years, and possible future installations of this type of clutch in U.S. Navy gas turbine generator sets.

The Design Development and Implementation Program (DDIP) evolved as a result of an organized progression of In-Service Engineering (ISE) responsibilities required to implement improvements to Gas Turbine Generator Sets (GTGS) in the U.S. Navy. The DDIP was established to bring a design concept, whether it be to correct a problem or to make a design improvement, from the drawing board through testing and development to the implementation of a Technical Directive as quickly as possible. Presently all engineering improvements on U.S. Navy Gas Turbine Generator Sets are implemented through the DDIP. Providing this central point of engineering has helped the Naval Sea Systems Command implement improvements in a well tested and timely manner. This paper describes the sequential processes in the DDIP methodology and further discusses specific engineering problems and solutions using the DDIP process.
