The engine helped the Il-76 aircraft test bed fly at speeds of 0.6 Mach in its maiden flight, according to the Defence Research and Development Organisation (DRDO). It was revealed that in the next few months 50-60 test flights would be carried out.
Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). [1] By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50–50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel.

The 1973 oil crisis increased oil prices in the 1970s, which caused engine manufacturers to research new technologies to reduce fuel burn, including open rotor (also known as propfan) engines. However, none of those designs made it to production aircraft, mostly due to decreasing oil prices and concerns over the high noise footprint of those ...
Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.
The HAL HTFE-25 ("Hindustan Turbo Fan Engine") is a 25 kN turbofan engine under development by Hindustan Aeronautics Limited (HAL). [1] The engine can be used in single engine trainer jets, business jets and UAVs weighing up to 5 tonnes and in twin engine configuration for same weighing up to 9 tonnes. Based on the technical feasibility, the ...
Fuel economy in air transport comes from the fuel efficiency of the aircraft + engine model, combined with airline efficiency: seating configuration, passenger load factor and air cargo. Over the transatlantic route, the most-active intercontinental market, the average fuel consumption in 2017 was 34 pax-km per L (2.94 L/100 km [80 mpg ‑US ...
Spectrometric Oil Analysis Program (SOAP) is a method used by aircraft operators, including several Air Forces of the World, to test the health of aircraft engines by performing frequent laboratory testing of the engine oil. The tests reveal the chemical composition of any metal particles suspended in the oil samples. By comparing the results ...
The 715 shp TPE331-6 used in the Beech King Air B100 have a 400-hr. fuel nozzle cleaning interval, 1,800-hr. hot section inspection interval and a 5,400-hr. time between overhaul; approval is possible for 3,000-hr. HSIs and 6,000-hr. overhauls and engine reserves are cheaper than for the PT6A.
