  Glossary

  turbocharger uses a small radial inflow turbine in the exhaust system to drive a centrifugal-type air compressor on the turbine shaft. The compressed air is directed into the engine cylinders to increase power. Turbo-compound engine. A reciprocating engine ... that has power recovery turbines in its exhaust system. The power extracted from the exhaust by these turbines is directed into the engine crankshaft through a fluid coupling. Turbofan engine. A type of gas turbine engine that…

  Chapter 1: Aircraft Engines › Gas Turbine Engines › Types & Construction

  reflected in the applicable maintenance manuals. One of the greatest single factors influencing the construction features of any gas turbine engine is the type of compressor or compressors for which the engine is designed. Four types of gas turbine engines ... power aircraft. They are the turbofan, turboprop, turboshaft, and turbojet. The term “turbojet” was used to describe any gas turbine engine used in aircraft. As gas turbine technology evolved, these other engine types were developed to take the place…

  Split-Shaft/Free Turbine Engine In a free power-turbine engine, such as the Pratt & Whitney PT-6 engine, the propeller is driven by a separate turbine through reduction gearing. The propeller is not on the same shaft ... basic engine turbine and compressor. [Figure 15-5] Unlike the fixed-shaft engine, in the split-shaft engine the propeller can be feathered in flight or on the ground with the basic engine still running. The free power-turbine design…
