How does a turboshaft engine work?
As a variation of the gas turbine, turboshafts are very similar to turbojets. The operating principle is identical: atmospheric gases are ingested at the inlet, compressed, mixed with fuel and combusted, then expanded through a turbine which powers the compressor.
What engine is in a Black Hawk?
General Electric T700Sikorsky UH-60 Black Hawk / Engine type
How does a T700 engine work?
The T700 hot section module consists of the combustion chamber, turbine and exhaust. The combustion chamber ignites and controls the burning fuel and air. It releases heat so the air expands and accelerates to provide a smooth and stable stream of uniformly-heated gas.

Who invented turboshaft engine?
Joseph Szydlowski
The first turboshaft engine for rotorcraft was built by the French engine firm Turbomeca, led by its founder Joseph Szydlowski. In 1948, they built the first French-designed turbine engine, the 100-shp 782.
Does a turboshaft engine produce thrust?
A turboshaft engine is a variant of a jet engine that has been optimised to produce shaft power to drive machinery instead of producing thrust.
What helicopter has the longest range?
The Lockheed AH-56A Cheyenne is the longest range helicopter with a flight range of 1225 miles.
Why does the Black Hawk have jet intakes?
It’s also worth noting that the modified engine intakes on this Black Hawk appear to help conceal the fan faces of its two turbine engines and dramatically clean up the area around the engine nacelles and forward doghouse area. These are all features that traditionally have a high degree of radar reflectivity.
How does a jet engine power a helicopter?
The gas turbine engine mounted on most helicopters is made up of a compressor, combustion chamber, turbine, and gearbox assembly. The compressor compresses the air, which is then fed into the combustion chamber where atomized fuel is injected into it. The fuel/air mixture is ignited and allowed to expand.
How often do helicopter engines have to be rebuilt?
For scheduled maintenance, most turboshaft engines offer times between overhaul (TBOs) ranging from 3,500hrs to 5,000hrs. While the TBO is a recommended interval for FAR Part 91 private flying, for Part 135 passenger-carrying and cargo charter operations it is mandatory.
What is the difference between a turboshaft engine and a turboprop engine?
The principal difference between the two is that the turboprop version must be designed to support the loads of the attached propeller whereas a turboshaft engine need not be as robust as it normally drives a transmission which is structurally supported by the vehicle and not by the engine itself.
