Figure 1. Basic Turboshaft Operation. Note the absence of a mechanical connection between the HPT and LPT. An ideal turboshaft extracts with the HPT only the power necessary to turn the compressor, and with the LPT all remaining power from the expansion process. A. Emphasis on Shaft Power.

Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. In aviation, these include helicopters and auxiliary power units (APUs). Basic arrangements are similar to turboprops except the drive systems are more elaborate.
Comparison of Helicopter Turboshaft Engines. Although they garnish less attention than their flashy jet cousins, turboshaft engines hold a specialized niche in the aviation industry. Built to be compact, efficient, and powerful, turboshafts have made modern helicopters and the feats they accomplish possible.
Far beyond the airplane turboprop or turbofan engine, the helicopter turboshaft engine controls the main rotor speed and therefore directly affects the flight capability, safety and transient manoeuvers of the helicopter. The first part of this paper describes the main characteristics of the turboshaft engine with magnitude orders.
Description of the T700-GE-700 Engine in a Helicopter Application The T700-GF_,-700 is a turboshaft engine used in pairs in the Army's Apache and Blackhawk helicopters. This 1600 horsepower-class, modular, two-spool engine (figure 1) consists of a gas generator section and a free power turbine [8].
