[/ycSf MAKCH 8, 1913. H.M.A. "DELTA. »» THIS airship, which was exhibited over the central aisle at Olympia, was built at the Royal Aircraft Factory in 1912, and is of the non-rigid type. It has a Continental fabric gas vessel of 180,000 cub. ft. capacity, and two engines of a joint power of 210-h. p. capable of propelling the ship at about 44 m.p.h. A car about 28 ft. in length is hung from the envelope Iry steel wires. In the car the steersman has a fixed seat, in front of which is a steering wheel arranged more or less on the motor car plan. There are also clutch pedals for each engine and throttle levers for controlling their power output. The compass, aneroid, and inclinometer are near by, and at night are illuminated by an electric light maintained by a C.A.V. battery system. On the port side is a wheel for swivelling the propellers. The propellers are carried at the ex tremities of a transverse tubular beam arranged between the envelope and the car. The swivelling apparatus enables them to be turned into any plane, and when leaving the ground they are used for exerting a direct upward lift. Similarly, when descending they are employed to pull the airship earthwards. By mounting the propellers on opposite sides of the axis, so that one is in effect a propeller and the other a tractor screw, their weights are The car of the "Delta," the War Office dirigible at.Oiympia. balanced, and the swivelling-gear is thus easier for control. A hand-wheel is used to operate the horizontal movable planes, which are called trimming-planes, and are in effect similar to the elevators of aero planes. These stabilising planes are placed aft on the envelope, with the Tudders. The envelope contains four automatic valves, those aft controlling the gas, while those forward communicate with the two air balloonets. There is an emergency gas valve and also two ripping panels in the top of the envelope, and on the bows is a special mooring attachment for use with the portable mast, which was designed and constructed at the Royal Aircraft Factory. Water ballast is carried in the car, and a pump is provided for its control. In order to avoid confusion, the pipes are painted in different colours, the water-pipes being blue, the petrol red, the oil yellow, and the compressed air pipes white. Control arrangements on H.M. A.. "Delta." Among the instruments on the dash is the "CA.V." switchboard for controlling the "C.A.V." lighting installation with which this vessel is equipped. *' Flight" Copyright.
