Description

The Naval Sea Systems Command (Integrated Power Systems Program Office) is soliciting information from sources of supply for high power density electric motors that have a capability to electrically start up to a 35,000 horsepower gas turbine engine used for surface ship propulsion and ship service power. The objective is to identify industry capability to meet no-load engine start requirements using commercially available hardware or hardware that can be readily modified. The following technical requirements are for the ultimate application, but motors/controllers that do not presently meet these requirements are still of interest if reasonable modifications can enable the motor to meet the requirements. The motor will have the following functions: starting the engine, motoring the engine for water washing, and motoring the engine for fuel purging. The motor shall have a controllable speed range of 0 to 4650 rpm. The motor is disengaged from the engine gearbox using an overrunning clutch mechanism after reaching 4650 rpm. The clutch should be included with the motor package. The motor shall be torque limited to 500 ft.-lb. from 0 to 2750 rpm (engine light off speed). Acceleration to 2750 rpm shall be done in less than 25 seconds. The motor torque requirement is based upon a load inertia of 450 lb.- ft2. The maximum not to exceed torque is 830 ft.-lb. A replaceable sheer shaft to protect the engine accessory gearbox between 1350 and 1500 ft.-lb is preferred. The duty cycle for motoring the gas turbine is 2000 rpm (1500 rpm water wash) 5 minutes on, 2 minutes off, 5 minutes on, 18 minutes off for any number of cycles or 10 minutes on, 20 minutes off for any number of cycles. The Navy is considering procuring and testing candidate non-developmental commercial engine electrical start systems (motor and controller) for a near term technology demonstration in May 2001 and a longer term investigation of system shipboard impacts. Information of interest to the Navy includes, but is not limited to: 1. A specification sheet for any motor that meets the technical goals listed above. The specification sheet should address all of the identified goals plus an estimate of price. 2. An indication of the potential supplier's experience in high speed, power dense motor production. 3. An indication of whether an off-the-shelf motor is available or if development is required. If development is required, the Navy would like a description of the modifications/development required, a cost estimate, and development schedule including factory acceptance testing. 4. An indication of the potential supplier's experience with gas turbines. 5. Whether the company would consider loaning an available system, or components, to the Navy for testing. No solicitation is available or specifically planned in the immediate future. The information requested is for information and planning purposes. Technical questions can be addressed to Mr. Don Schmucker, NAVSEA 05Z3, 703-602-0450 x118. All responses shall be submitted to either the PCO or technical contact by 1 November 2000. Email responses can be sent to boyerdl@navsea.navy.mil or schmuckerdh@navsea.navy.mil.
