Gas turbine power requirements for the U.S. Army vary tremendously depending upon the specific application, spanning the power range from a few Watts for individual soldier power supplies to Megawatt-scale engines for heavy land vehicles and air transport. Each application has its own set of key drivers which constrain the selection of an engine technology and in optimizing the design, the objective function dependencies vary widely. Hence, although the desire for compactness, efficiency, lightness, low observables, etc. is universal among the common Army applications, their relative importance is not. In addition, certain applications may require an engine attribute which is wholly unimportant in other cases, such as the need for heat andor air conditioning in a distributed generation unit. Thus flexibility in the design of any type of engine is a significant advantage if it is to find a niche in several applications, an obvious benefit to minimizing Army inventories and costs.
