Fokker F27 Friendship

The F27 was developed during the early 1950s with the intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the Douglas DC-3.

A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation.

In the aftermath of the Second World War, twin-engine all-metal monoplanes such as the successful Douglas DC-3 airliner dominated commuter aviation.

[1] By 1951, figures within Fokker were urging that design work be undertaken on a prospective 32-seat airliner intended as a direct replacement for the popular DC-3.

[2] Fokker sought the opinions of existing DC-3 operators on what performance increases and refinements they would expect of a new model of commuter aircraft.

[1] The Dart engine had already proven successful on the early models of the Vickers Viscount, while a high-mounted wing had been selected as it produced a higher lift coefficient than a lower counterpart, it also enabled easier ground loading due to a lower floor level and provided unfettered external views to passengers without any weight increase.

[1] Via modifications such as the adoption of improved engines, rearranged loading doors, elongated fuselages, and other changes, several different models of the F27 were developed and made available for commercial operators.

Although originating from the F27-500 airframe, the Fokker 50 was virtually a new aircraft, complete with Pratt & Whitney Canada engines and modern systems, which led to its general performance and passenger comfort being noticeably improved over the F27.

[citation needed] In November 1958, the first production aircraft, an F27-100 model, was delivered to Irish airline Aer Lingus; it performed its first revenue flight in the following month.

[citation needed] Initial sales for the type were slow, which led to Fokker seeking financial support from banks and from the Dutch government in order to maintain production of the airliner while more customers were sought.
