Large shipboard gas turbines are traditionally started by means of an air motor (starter). In the absence of bleed air from another operating gas turbine, the starters are driven by stored high pressure air. Onboard gas turbine powered compressors, auxiliary power units (APUs) would offer improvements over using stored high pressure air for starting. Certain APUs have demonstrated extreme reliability in aircraft applications. However, the concept of APU use has not come to fruition on a U.S. Navy surface combatant. The focus of this paper is on an APU test done at the Naval Ship Systems Engineering Station's (NAVSSES's) gas turbine test site for DDG-51 Class destroyers. Since starting scenarios are similar among the U.S. Navy's gas turbine ships, a potentially broad base exists for this applications.
