From piston engines to turbojets and high bypass turbofans , aircraft engines have come a long way in pushing the limits of propulsive efficiency . Among many state-of-the-art engines, here is a list of some of the most iconic aircraft engines that revolutionized the world of aviation. 1 Rolls-Royce Dart First introduced in 1948 Avro 748 (Hawker Siddeley 748) Cavalier Turbo Mustang III Fairchild F-27 Fokker F27 Friendship Grumman Gulfstream I Douglas DC-3 Convair 600 and 640 Boeing B-17F Flying Fortress The Rolls-Royce Dart is a turboprop engine that combines the power of jet propulsion with the efficiency of propellers.
The engine was widely used in the first generation of turboprop-powered aircraft, including the Dutch Fokker F-27 and British Vickers Viscount. With a two-stage centrifugal compressor, seven straight-flow combustion chambers, and a three-stage axial turbine, the engine produced 1,354 kW of power, rotating at approximately 15,000 RPM. The Dart enabled much lower operating costs than its predecessors with greater speed and comfort.
The engine remained in production for nearly forty years until the last Fokker F27 Friendships and Hawker Siddeley HS 748s were produced in 1987. The manufacturer only produced 50 examples of the type. 2 Pratt & Whitney JT3 First entered service in 1958 Boeing 707 Boeing 720 Douglas DC-8 Boeing B-52H Stratofortress Boeing C-135 series Boeing E-3 Sentry Northrop Grumman E-8 Joint STARS Lockheed C-141 Starlifter The PW JT3 entered comm.
