What is turboshaft engine used for?
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. Turboshaft engines are most commonly used in applications that require a small, but powerful, light weight engine, inclusive of helicopters and auxiliary power units.
Where are turboshaft engines used?
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.
Which aircraft uses turboshaft engine?
The application of gas turbine engines in helicopters is discussed. The work- ings of turboshafts and the history of their use in helicopters is briefly described. Ideal cycle analyses of the Boeing 502-14 and of the General Electric T64 turboshaft engine are performed.
How much does a helicopter turbine engine cost?
Helicopter turboshaft engines regularly used in Business Aviation are generally similar in size and power output to turboprop engines utilized in BizAv. Turboshaft maintenance costs are also generally similar turboprop engine costs. Helicopter operators can expect to pay $100k to $300k per engine, per shop visit.
What kind of propulsion system does the F-35B use?
The complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001. The F-35B STOVL variant of the Joint Strike Fighter (JSF) aircraft was intended to replace the McDonnell Douglas AV-8B Harrier II and the McDonnell Douglas F/A-18 Hornet used by the United States Marine Corps.
Where was the F-35B vertical hover demonstration?
On 18 March 2010, a STOVL equipped F-35B performed a vertical hover and landing demonstration at Patuxent River Naval Air Station in Lexington Park, MD.
Where was Rolls Royce X-35B LiftSystem test conducted?
During the final qualifying Joint Strike Fighter flight trials, the X-35B took off in less than 500 feet (150 m), transitioned to supersonic flight, then landed vertically. Ground tests of the F136/LiftSystem combination were carried out at the General Electric facility in Peebles, Ohio in July 2008.
What is the weight of the Rolls Royce LiftSystem?
The weight of the AV-8B is about 46% of the weight of the F-35B . Like lift engines, the added LiftSystem components are dead weight during flight, but the advantage of employing the LiftSystem is that its greater lift thrust increases takeoff payload by an even larger amount.
