The Fokker F26 was an early jet airliner design by the [Vous devez être inscrit et connecté pour voir ce lien] manufacturer, [Vous devez être inscrit et connecté pour voir ce lien].

Development

During the era before the [Vous devez être inscrit et connecté pour voir ce lien], Fokker was one of the world's largest manufacturers of passenger aircraft.

After the re-emergence of the Fokker company in 1945 (its founder, [Vous devez être inscrit et connecté pour voir ce lien], had died in the [Vous devez être inscrit et connecté pour voir ce lien] 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 a [Vous devez être inscrit et connecté pour voir ce lien].

The design materialised through cooperation between Fokker, the Dutch airline company [Vous devez être inscrit et connecté pour voir ce lien], and the Dutch national institute for aircraft development, the Nationaal Instituut voor Vliegtuigontwikkeling (NVI).

Design progressed quickly and a model of the F26 was shown at the first postwar aviation fair, the [Vous devez être inscrit et connecté pour voir ce lien] 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 executive Mr 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 manufacturer [Vous devez être inscrit et connecté pour voir ce lien].

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, the [Vous devez être inscrit et connecté pour voir ce lien].

In its publications the Fokker Company often stated that the F26 Phantom was a conceptual design.

Its purpose was to be a technical and economical feasibility study only.

Therefore the F26 was never intended to become reality.

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.

Regardless the real business expectation was, the significance of the F26 design lies in its early appearance.


Although the aircraft industry in general considered jetpowered aircraft to be the future, no jetpowered passenger aircraft were designed by then.

Design

The all-metal F26 design consisted of a low-wing layout with a 17-seat [Vous devez être inscrit et connecté pour voir ce lien], a fully retractable [Vous devez être inscrit et connecté pour voir ce lien] and two [Vous devez être inscrit et connecté pour voir ce lien] RB.41 series I [Vous devez être inscrit et connecté pour voir ce lien].

With a thrust of 2.3 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 passenger [Vous devez être inscrit et connecté pour voir ce lien] had a single aisle layout, with two seats abreast on the right and a single row on the left.

The aft side had a [Vous devez être inscrit et connecté pour voir ce lien] section and two cargo bays.

The aircraft was to be flown 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).
