The LIO-320 is a "left-handed" version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine. [ 2 ] [ 3 ] The first O-320 (with no suffix) was FAA certified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine was later re-designated, without change, as the O-320 ...
Jet fuel vs oil prices. Oil prices increased about fivefold from 2003 to 2008, raising fears that world petroleum production is becoming unable to keep up with demand. The fact that there are few alternatives to petroleum for aviation fuel adds urgency to the search for alternatives. Twenty-five airlines were bankrupted or stopped operations in ...
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 ...
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 Ranger L-440 (company designation 6-440C) are six-cylinder inline inverted air-cooled aero-engines produced by the Ranger Aircraft Engine Division of the Fairchild Engine and Airplane Corporation of Farmingdale, New York, United States. The engine was mainly produced for Fairchild's family of training aircraft in the mid-1930s.
[21] [22] Many light aircraft are powered by versions of these engines, with power ratings in the 100–360 hp (75–270 kW) range. Engines in this series also include the O-235 four-, O-580 six- and O-720 eight-cylinder engines, and the advanced turbocharged and fuel-injected 450 hp (340 kW) TIGO-541 variant of the venerable (carbureted) O-540.
O-360 family engines are also widely used in airboats, most notably in the Hurricane Aircats used by the US Army during the Vietnam War. [ 3 ] The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2. [ 4 ]
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.
