[79] Type 663 Second prototype, testbed for Rolls-Royce Tay turbojet. [18] Type 640 Planned third prototype, to be powered by four Napier Naiad turboprops. Not built, with parts ...
The HS 748 was developed during the late 1950s as a move to re-orient the company towards the civil and export markets. Powered by the popular Rolls-Royce Dart turboprop engine, it was specifically designed as a modern feederliner to act as a replacement for the aging Douglas DC-3s then in widespread service. Originally intended to seat a ...
The propulsion was significantly revised from that of the HS 748; the twin Rolls-Royce Dart turboprop engines of its predecessor were substituted for Pratt & Whitney Canada PW126 engines, a more modern counterpart.
A twin turboprop airliner, the Avro 748, was developed during the 1950s and sold widely to airlines and governments across the globe, powered by two Rolls-Royce Dart engines. The RAF bought 6 for use by the Queen's Flight and a variant with a rear-loading ramp and a "kneeling" main undercarriage was sold to the RAF (31 aircraft) as the Andover .
