Bristol Hercules aircraft engine 3D model

Bristol Hercules engines were used from 1939 into the 1950s to power many different aircraft, both military and civilian. The most famous of which were the Lancaster, Beaufighter, Halifax, Wellington and the Vickers VC.1 Viking. Over 57,400 were produced by the Bristol Engine Company. It was a 14-cylinder, two-row, supercharged, air-cooled radial engine with a bore of 5.75 in (146 mm), stroke of 6.5 in (165 mm) that gave a 2,360 in³ (38.7 litre) displacement. It was 53.15 in (1,350 mm) long, 55 in (1,397 mm) in diameter and weighed 1,929 lb (875 kg). Power output was 1,272 hp (949 kW) at 2,800 rpm for takeoff and 1,356 hp (1,012 kW) at 2,750 rpm at 4,000 ft (1,220 m). The model accurately shows the most important parts, especially what would be seen when the engine is mounted on an aircraft. Wiring and details at the back of the engine have been omitted because insufficient photos and drawings could be found.
