TheFokker F26 was an early jet airliner design created by theDutchaircraft manufacturer,Fokker.

Development

[edit]

During the era before theSecond World War, Fokker was one of the world's largest manufacturers of passenger aircraft.[citation needed] After the re-emergence of the Fokker company in 1945 (its founder,Anthony Fokker, had died in the United States in 1939), the company made ambitious plans for reconquering the market it once dominated. Therefore, in 1946, the company came up with a design of ajetliner.

The design materialised through cooperation between Fokker, the Dutch airline companyKLM, and the Dutch national institute for aircraft development, the Nationaal Instituut voorVliegtuigontwikkeling (NVI). Design progressed quickly and a model of the F26 was shown at the first postwar aviation fair, theParis Air Show of November 1946. The model attracted a lot of interest, but no orders were gained.

Further development of the F26 was hampered by the attitude of KLM. KLM executiveMr Plesman believed that design, marketing and production of a jetliner was too big a project for Fokker alone. He therefore pushed Fokker for cooperation with British manufacturerde Havilland. Although some cooperation took place, mainly on engine-related issues, a combined effort in producing jetliners never took place. However, within ten years, Fokker would develop a more feasible design, theturboprop-poweredF27 Friendship.

The F26 Phantom was a conceptual design that was to be a technical and economical feasibility study only. Therefore, the F26 was never intended to become reality.[1] On the other hand, the Fokker Company expressed the expectation at the Paris Air Show of 1946 that the aircraft was about to fly in three years time.[citation needed] Regardless of what the real business expectation was, the significance of the F26 design lies in its early appearance. Although the aircraft industry in general considered jet-powered aircraft to be the future, no jet-powered passenger aircraft were designed by then.

Design

[edit]

The all-metal F26 design consisted of a low-wing layout with a 17-seatpressurizedfuselage, a fully retractablegear and twoRolls-Royce Nene RB.41 series Ijet engines. With a thrust of 23 kN (5,171 lbf) each, these engines were the most powerful engines available at the time. The aircraft was designed for a flight crew of three people.

The passengercabin had a single aisle layout, with two seats abreast on the right and a single row on the left. Atoilet was located in the aft of plane and there were two cargo bays. The aircraft was to be crewed by two pilots and one radio operator.

Based on design studies the F26 had an economical cruise speed of 800 km/h (497 mph) with a range of 1,000 km (621 mi).
