What uses a turboshaft engine?
Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment.

What is the difference between turboprop and turboshaft?
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.
How much powerful is jet engine?
1 Megawatt equals 1341 horsepower. For an aircraft like a Boeing 777 with two GE 90-115B engines each engine produces roughly 23 Megawatt of power during cruise flight with a fully loaded aircraft. This is 30.843 horsepower.
Do helicopters use jet engines?
Although some small helicopters still use piston engines (also called reciprocating engines, similar to the ones used in cars and trucks), most now use gas turbines more like the jet engines on conventional airplanes. Most modern choppers have turboshaft engines, which are similar to normal jet engines on airplanes.
How long does a helicopter engine last?
When is helicopter engine maintenance required? 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.
How often do you rebuild a helicopter engine?
It requires that the entire helicopter be overhauled every 12 years or 2200 hours of flight time, whichever comes first. It does this by syncing the life on certain components so they all need to be inspected, rebuilt, or replaced at the same time.
Why do helicopters use turboshaft engine?
Helicopters use turboshaft gas turbine engines once helicopters begin to have over 4 seats. The lightweight, small, gas turbine engines produce more power for their size compared to piston engines and therefore helicopters are able to lift more. This equates to more passengers, cargo & fuel.
How does a turboshaft work?
Turboshafts are an adaptation of gas turbine technology in which the principle output is shaft power from the expansion of hot gas through the turbine, rather than thrust from the exhaust of these gases. As a variation of the gas turbine, turboshafts are very similar to turbojets.
How many horsepower is a 747 engine?

When was the second GE turbine engine tested?
A second HPW3000 was tested for performance and sand ingestion during late summer 2014. In February 2017, the Army designated the HPW3000 design as the T900-HPW-900 engine. Since 2010, GE has been developing and testing T901 -specific technologies. The second GE3000 was tested for performance, endurance, and sand ingestion in late spring 2014.
What is the single spool architecture of GE T700?
GE has maintained the T700 single spool architecture for modularity and reliability with additive manufacturing and ceramic matrix composites (CMCs) from the CFM LEAP, GE9X or GE ATP .
What kind of engine is the GE T901?
The General Electric T901 ( GE3000) is a turboshaft engine in the 3,000 shp (2,200 kW) class currently under development for the United States Army ‘s Improved Turbine Engine Program (ITEP).
What’s the difference between ATEC and GE turbine engines?
The major difference between the ATEC HPW3000 (T900) and the GE3000 (T901) engines is in the number of rotating compressor/turbine assemblies in the gas generator stage. The ATEC T900 is a dual-spool turboshaft, while the GE T901 is a single-spool design.
