GAS TURBINE ENGINE POWER AUGMENTATION AND EMERGENCY RATING

Abstract

Methods of obtaining altitude hot day and emergency one-engine-out power augmentation were analyzed to determine the characteristics of combined engine-augmentation systems which were capable of satisfying the divergent vehicle-engine power matching requirements of helicopter-type vehicles at minimum cruise, takeoff from 6000 feet at an ambient temperature of 95F and emergency one-engine-out takeoff. The combined engine-augmentation systems which satisfied these requirements were then rated on the basis of their complexity; any advantages, disadvantages, and limitations associated with their use; and a merit factor based on the total installed system and fuel weight required to perform a typical mission. Based on the results of these studies selections were made of the engine-augmentation systems which were optimum for supplying altitude hot day takeoff power only, emergency one-engine-out takeoff power only, and both types of augmentation from a single system.
