However he kept going until his engine was hit in the carburettor and engine bearers, which, of course, forced him to land.

The front struts terminated at the engine bearers, which were midway between the upper and lower longerons.

Normal engine bearers could not be used so the unit was held in the test stand by two conical mounts that attached to the crankcase.

In front of him the structure was wire braced, the longerons converging to become overhung engine bearers.

A long icicle was hanging from the middle of the radiator where the fan had been driven into it by the impact; the engine bearers had sheared.

The construction was primarily of spruce, with ash used in parts of the engine bearers and undercarriage beams, with doped linen stretched over it.

The engine bearers burned through and the aircraft was finally crash landed by the pilot, Squadron Leader Hedley Hazelden in a field.

The blisters which had formerly covered the spent shell-casing chutes of the MG 131s became more streamlined and were lengthened and enlarged to cover both the weapons and the engine bearers.

The B.E.7 was also taken on charge by the Central Flying School, serving until November 1913, at which time its engine bearers were found to be damaged by the heat of its exhaust fumes.

In order to reduce weight and frontal area, the engine was mounted directly to the forward fuselage, which was strengthened and literally tailored to the DB 601, as opposed to conventional mounting on engine bearers.

Engineers Ilic and Sivcev at the Ikarus plant Zemun, outside Belgrade, made the conversion by the fitting of new engine bearers, cowlings and cooling system manufactured at the Ikarus factory.

A rectangular rudder was carried on two booms extending aft, the lower attached to the apex of inverted V struts below the engine bearers, which also supported the long skid projecting back from below the lower wings's leading edge.

One Typhoon, R8694, was used by Napier for trials with the more powerful Sabre IV, cooled using an annular radiator and driving a four-bladed propeller; the new engine and radiator arrangement required substantial modifications to the forward fuselage and engine bearer structures.

Frame 5, to which the engine bearers were secured, supported the weight of the engine and accessories, and the loads imposed by the engine: this was a strengthened double frame which also incorporated the fireproof bulkhead and, in later versions of the Spitfire, the oil tank.

Soon obsolete as a front-line aircraft, it came into its own as a trainer, with thousands being built in the war, with major production types being the 504J and the mass production 504K, which was designed with modified engine bearers to accommodate a range of engines, in order to cope with engine shortages.

Initial prototype versions were symmetrical, but as larger superchargers were fitted, the engines required modified upper engine bearers to clear the supercharger housing, and as a result the final shape of the new cowling was asymmetrical, being enlarged on the port size where the supercharger was mounted on the DB engine.
