  • Armstrong Whitworth AW.660 Argosy




    The Armstrong Whitworth Argosy was a British post-war transport/cargo aircraft; it was the final aircraft to be designed and produced by aviation company Armstrong Whitworth Aircraft.

    General Information

    Although given different internal design numbers, the AW.650 civil and AW.660 military models were, for most practical purposes, the same design, while both models also shared the "Argosy" name.


    The Armstrong Whitworth Argosy was a general-purpose transport aircraft largely used for freight operations by both military and civil operators. At the time of its introduction, the type was considered to be unique in its class. Principally designed as a freighter, the aircraft could be tasked with other mission types. The Argosy was offered in a convertible configuration for carrying both freight and passengers; the civil variant could accommodate a maximum of 80 passengers while providing comfort and speed conditions comparable to the contemporary Vickers Viscount airliners. In the cargo role, the Argosy was designed to facilitate rapid turnaround times of only 20 minutes without the use of lifting trucks or cranes, utilising pallets and rollers to eliminate packaging.


    In terms of its basic configuration, the Argosy's tailplane was mounted on twin booms that ran rearwards from the inner engine nacelles, leaving the cargo doors at the rear of the fuselage clear for straight-in loading, while sideways-opening doors were fitted at both ends of the fuselage, the flight deck being set at high up position upon the aircraft's nose. This configuration allowed for an unobstructed cargo space measuring 10 by 47 feet (3.0 m × 14.3 m) with a sill height corresponding to that of a normal flatbed truck. It possessed a maximum weight of 88,000 lb (39,915 kg) and a payload of 28,000 lb (12,700 kg). When cruising at 276 mph (444 km/h), it had a range of 1,780 mi (2,865 km) and could seat a maximum of 89 passengers.


    The Argosy is best known in Australia as the yellow turboprop operated by Ipec Air.
