The Rolls‐Royce Spey Junior Turbofan Engine: The design background to the Spey Junior powerplant for the Fokker F‐28 Fellowship short haul airliner

Abstract

THE choice of a version of the Rolls‐Royce Spey to power the new Fokker short haul airliner maintains the close association between the two companies which began more than forty‐seven years ago. The first instance of a Rolls‐Royce engine powering an aircraft of the Royal Netherlands Aircraft Factory was as early as 1920, when a 365 b.h.p. Eagle VIII engine was installed in the Fokker F.111‐W float plane. Following this, a number of other Fokker aircraft were powered by Rolls‐Royce piston engines. With the advent of the gas turbine, the co‐operation continued with the very successful Dart turboprop powered Friendship, well over 400 of which have so far been sold, and is now developing with the selection of the Spey Junior to power the Fellowship.
