When the large detachable panels are removed there is very free access to the Rolls-Royce Merlin engine. - pipe shown is part of the Glycol cooling system, "W The large tungum so that the machine is very stable on the ground and can be turned in a small circle at quite high speed without turning over. The telescopic leg, a Vickers oleo- pneumatic, is hinged to the bottom boom of the centre- section front spar. One member braces it in a fore-and- aft plane and another in a lateral plane. The hydraulic jack operates the latter, which is of the " broken " type. When this strut is " broken " by the jack, the telescopic leg swings inwards, and as the drag strut of the under- carriage is pivoted around a higher centre, it brings the wheel back as well as inwards. This is neces- sary in order to enable the wheel to clear the front spar when retracted. When the wheel is down it is in the plane of the spar. Fairings attached to the outside of each undercarriage close the opening in the wing surface when the undercarriage is retracted. Two independent systems of operation are provided for the undercarriage. The main system is power operated and has hydraulic transmission. The auxiliary system is also hydraulic, but is hand operated. Should anything go wrong with both systems there is an arrangement of cocks whereby the pilot can release all pressure in the hydraulic systems and release the catches which hold the wheel? up. The weight of the wheels then brings them into the "down " position The Rolls-Royce Merlin II engine is mounted ' Flight " photographThe split flaps of the Hurricane extend from radiator casing to root of ailercn. Theyare hydraulically operated. on a simple steel tube structure in the nose of the fuse- lage. Large detachable panels in the cowling give access to most of the parts of the engine likely to need inspection or adjustment. The radiator of the liquid-cooling system is placed under the fuselage, with an oval entry in front of the radiator and a rectangular opening aft of it. The opening in the aft end of the radiator housing is covered with a hinged flap by means of which the pilot can vary the amount of cooling. An interesting feature of the cooling system is the use throughout of tungum pipes.
