AUSTIN A.F.T.3 OSPREY

  A private venture intended to compete with the Sopwith Snipe, the Osprey was of wooden construction with fabric skinning and was powered by a 230 hp Bentley B.R.2 nine-cylinder rotary engine. Armament comprised two fixed and synchronised 0.303-in (7,7-mm) Vickers machine guns and one semi-free Lewis gun of similar calibre on the rear spanwise member of the middle-wing centre section. The Osprey was flown for the first time in February 1918, but performance proved to be inferior to that of the Snipe, and construction of second and third prototypes was abandoned.

Max speed, 118mph (190 km/h) at 10,000ft (3 050 m), 110 mph (177 km/h) at 15,000 ft (4 570 m).
Time to 10,000 ft (3 050 m), 10.35 min.
Endurance, 3 hrs. Empty weight, 1,106 lb (502 kg).
Loaded weight, 1,888 lb (856 kg).
Span, 23 ft 0 in (7,01m).
Length, 17 ft 7 in (5,36 m).
Height, 10 ft 8 in (3,25 m).
Wing area, 233 sq ft (21,64 m2).

Osprey. In addition to two synchronised Vickers guns on the fuselage decking forward of the cockpit, and having ejection chutes in the fuselage sides, the single-seat Osprey (1917-18) had provision, as had competitive fighters, for a Lewis gun with a limited arc of movement. The aircraft being a triplane, this was mounted on the rear spar of the 'centre centresection'. The actual installation was in dummy form only (land-service type, with 'single' drum).

If nothing else this trim-looking triplane helps illustrate the point that for every winning design, a number of other design submissions fall by the wayside. First flown in February 1918, the company-funded Austin AFT 3 Osprey was designed to meet the same Air Board's Type A 1(a) requirement that led to the production contract for Sopwith's Snipe. Powered by a 230hp Bentley BR 2, the Osprey's top level speed was 118.5mph at 10.000 feet, this height being reached in 10 minutes 20 seconds. Armament consisted of three forward-firing .303-inch guns, of which two were fixed and synchronised Vickers, backed by an overwing Lewis that could be swivelled in elevation for 'belly-raking' an adversary's underside. Only the first of the three examples on which work had commenced was to be completed and flown. It is seen here at Farnborough in mid-June 1918, following its Martlesham Heath trials of March 1918.
