The Antonov An-24 (Coke) is a 52-seater a short-range twin turboprop aeroplane developed during the 1950s, similar to the Fokker F 27 Friendship. The An-24 is powered by two ZMDB Progress AI-24A turboprops providing a top speed of 498 kmh and a range of 640 km fully laden, increasing to 3000 km empty. The An-24 is fitted with high wings to minimize the risk of propeller damage on the USSR's many unsurfaced landing strips. Aeroflot's vast fleet contains more An-24s than any other airliner; over 1,000 fire-fighting, aerial survey and passenger versions have been built. The An-24 was adopted for military service in 1962 as a short-range utilityfreight transport aircraft. The military version of the An-24 carries a flight crew of five and up to 38 troops or 30 paratroops or 24 litters and one attendant or 4612 kg of freight in the hold. Research AN-24
The Fairchild F-27 was an American-built version of the Dutch Fokker F 27 twin-turboprop airliner, and was first flown in 1958. The Fairchild F-27 was a high-wing cantilever monoplane produced in various models with different engines. The standard Fairchild F-27 was powered by two Rolls-RoyceRDa.6 Dart 511 engines providing a cruising speed of 435 kmh and a range of 2720 km. The standard Fairchild F-27 carried 40 passengers. The Fairchild F-27A model was fitted with two more powerful Rolls-RoyceRDa.7/1 Dart 528 engines providing a cruising speed of 494 kmh and a range of 3450 km. Research Fairchild F-27
The Fairchild FH-227 was an American elongated version of the Dutch Fokker F 27 twin-turboprop airliner, developed from the Fairchild F-27 which was first flown in 1958. The Fairchild FH-227 was a high-wing cantilever monoplane that was developed through the Fairchild FH-227A and the Fairchild FH-227B model which was powered by two Rolls-RoyceRDa.7 Dart 532-7 turboprop engines providing a cruising speed of 473 kmh and a range of 4315 km. The original Fairchild FH-227 carried between 44 and 52 passengers and the Fairchild FH-227B carried between 44 and 56 passengers. Research Fairchild FH-227B
The Fokker F 27 Friendship is a Dutch short/medium-range passenger airliner developed after the Second World War and first flown in 1955 as a prototype and in 1957 as a production aircraft. The Fokker F 27 is a high-wing cantilever monoplane produced in a number of variations, including civilian and military models, the civilian models typically having a passenger capacity of between 32 and 40 passengers. The Fokker F 27 is powered by two Rolls-RoyceDartRDa.7 Mk 536-7R turboprops providing a top speed of 480 kmh and a range of about 1850 km depending upon variant and load. The Fokker F 27 Maritime is a military medium-range maritime reconnaissance version. Research Fokker F 27
The Fokker F 28 FellowshipMK 4000 is a Dutch short/medium haul commercial airliner. The Fokker F 28 was launched as a successor to the Fokker F 27 in 1962. It is smaller and lighter than other contemporary twin-jets such as the BAe One-Eleven. Highly manoeuvrable in flight, it is designed for STOL with a wing sweepback of only 16 degrees for good handling at low speed, leading-edge slats and double-slotted flaps. There are no thrust-reversers; instead, the F 28 has powerful air brakes which, uniquely, form the tail end of the fuselage, and highly effective wheel brakes. This aircraft can take off from 6,000-foot long runways, or at altitudes as high as 15,000 feet. The F 28 was produced in a cooperative risk-sharing programme in which Shorts of Belfast designed the rear fuselage, MBB of West Germany the pods for the Rolls-RoyceSpey turbofan engines, and Fokker's German partner VFW, the tail and other fuselage sections. It is powered by two Rolls-Royce RB 183-2 SpeyMk 555-15H turbofans giving a top speed of 843 kmh and a range of up to 4000 km
depending upon load. The F 28 carries a crew of two or three and 85 passengers seated five-abreast. Research Fokker F 28
