The Royal Aircraft Factory B.E.12 was a British single-seat aeroplane of The First World War designed at the Royal Aircraft Factory. It was essentially a single-seat version of the B.E.2.

The Royal Aircraft Factory’s BE12 was an attempt to provide a more powerful single seat fighter version of the BE2c by fitting the Farnborough-based factory’s own 12-cylinder air-cooled power plant that would enter production as the RAF 4a.

2019年5月19日 · One 104 kw (140 hp) RAF 4a 12-cylinder VEE air-cooled engine. Two 7.69 mm (0.303 in) Lewis machine guns; bomb load of two 51 kw (112 lb) or sixteen 7 kg (16 lb) bombs. The BE.12 was a single-seat fighter developed in 1915. The prototype was a re-built BE.2c (serial 1697), being a two-bay equal-span biplane with a Royal Aircraft Factory 4a engine.

The single-seat fuselage of the BE.12a was employed, but the RAF 4a engine was replaced by the 200 hp Hispano Suiza engine used to power the SE5a. So crude was the modification that the fuel tank used on the BE.12a, which possessed a dorsal wedge-shaped fairing to align with the air scoop, fitted between the cylinders of the RAF engine, was ...

2021年8月11日 · The Royal Aircraft Factory B.E.12 was a British single-seat aeroplane of The First World War designed at the Royal Aircraft Factory. It was essentially a single-seat version of the B.E.2. The B.E.12 was pressed into service as a fighter, in which role it proved disastrously inadequate, mainly due to its very poor manoeuvrability.

The BE12 was a conversion of a BE2c with the observers cockpit in the front replaced by a large fuel tank and the engine replaced by a more powerful 150 hp RAF 4 engine. It was designed for the role of long range reconnaissance and as light bomber.

Initial production version powered by a RAF 4a engine – basically a B.E.2c conversion (250 built by Daimler, 50 built by Standard Motors) B.E.12a: With the wings and tail unit of the B.E.2e (50 built by Daimler, 50 built by Coventry Ordnance Works) B.E.12b

2009年4月9日 · The Royal Aircraft Factory B.E.12b was a higher powered version of the basic B.E.12 that was designed as a Home Defence aircraft but that entered service after the Zeppelin raids it was designed to counter had almost stopped. The prototype B.E.12b was produced by fitting a 200hp Hispano-Siuze engine to a standard B.E.12.

In an attempt to improve the performance of the B.E.12, primarily for the benefit of Home Defence squadrons, a 200hp Hispano-Suiza water-cooled eight-cylinder Veetype engine was substituted for the 150hp R.A.F.4a.
