Surface Ship Machinery - A Survey of Propulsion, Electrical, and Auxiliary System Development
Abstract
Propulsion, auxiliary and electric machinery targeted for future surface combatants is surveyed overall system characteristics are treated to permit as broad as possible coverage of development activities. Prime movers in both propulsion and ship service sizes are discussed. All will demonstrate improved economy, especially at part power, and increased attention to thermal and acoustic signatures. Gas turbines will remain the uncontested source of propulsion power, but rotaries may join diesels and turbines in ship service application. Electric drives may be selected where machinery is widely separated or geometries are restrictive. Reversing motors or reversing gears will provide backing power without the inefficiencies of controllable pitch (CP) propellers. Transmission component improvements including surface hardened gears and composite shafts will increase power density. Keywords: Air compressor, Centrifugal pump, Composite piping, Composite shafting, Contrarotating transmissions, Distribution hardware, Electric drive, Electric load equipment, Electric power generation, Gas turbines, Heat transfers mechanical reversing systems, Molecular sieve, Positive displacement, Reverse osmosis, Refrigerant compressor.
