Figure 3 Turbofan engine, TFE731-60 (Honeywell Engines & Systems).
HP.hr. The U.S. army’s main battle tank, Abrams M1A1, is propelled by
the AGT1500 turboshaft engine, rated at 1,500 HP. It is fitted with a
recuperator and operates on the regenerative Brayton cycle. Here, the
wheels are directly driven through a speed-reduction gear train to reduce the
rotational speed from about 22,000 rpm (power turbine) to 3,000 rpm at the
wheels. A new recuperated turboshaft engine, LV100, is currently in design
at Honeywell Engines and GE Aeroengines to drive future Abrams and
Crusader battle tanks.
2. Auxiliary power units (APUs), Fig. 4. These are small engines
(100–1,100 HP) used for air conditioning and lighting purposes in regional,
executive, narrow, and wide-body commercial as well as military aircraft.
They are also used to propel ground carts. As opposed to turbofan and
turboprop engines that have axial compressor and axial turbine stages, these
may have only centrifugal compressors and radial inflow turbines.
3. Marine applications. These include Fast Ferry transport engines,
Ocean Patrol, and Hovercraft.
4. Industrial turbo-generators. These may range from small engines
producing only 75 kW to 20 MW or more for power production.
