FLIGHT, SEPTEMBER 23, 1932 AT SHANKLIN The 70 ft. by 40 ft. by 12 ft. hangar built for Portsmouth, Southsea & Isle of Wight Aviation, Ltd. A clear opening of 50 ft. is provided by the doors. Housing Aeroplanes ^lITEROPLANES spend by far the greater part of £~AJI their life on the ground, and therefore, wherever CS JlL they are operated there arises the necessity for hangar accommodation both to provide con venient facilities for overhauls and also to avoid deteriora tion of both airframe and engine by protection from the elements. The firm of Boulton & Paul, of Norwich, well known not only as aircraft manufacturers but also as constructional engineers, specialise in the design and construction of steel hangars of all types suitable for housing either the light aeroplane of the private owner or the fleet of machines of the flying school or operating company. Being also the only firm engaged in the manufacture of aircraft who possess a building and constructional engineering depart ment, they are specially competent to deal with all ques tions appertaining to the housing of aircraft. Our illustrations depict hangars recently erected by this firm for Portsmouth, Southsea & Isle of Wight Aviation, Ltd., at Shanklin, in the Isle of Wight ; for Hillman's Airways at Romford and for Air Service Training, Ltd., at Hamble. The hangar at Shanklin is 70 ft. by 40 ft. by 12 ft., with steel doors arranged to give a clear opening of 50 ft. That at Romford is 90 ft. by 30 ft. by 15 ft., with doors arranged to give an opening for the full length of the building on one side, and that at Hamble is 300 ft. by 70 ft. by 18 ft., with steel-framed doors 18 ft. high by 12 ft. 6 in. wide running on Henderson track along all one side of the building. All these hangars typifv Boulton & Paul design, which ensures the provision of hangars of sturdy construction at low prices, with good accommoda tion and excellent lasting qualities. AN AMPLE INTERIOR : Air Service Training at Hamble like plenty of room for their machines, and they get it in this B. &. P. hangar, which is 300 ft. long and 70 ft. wide. 903 In addition to the above, Boulton & Paul have supplied hangars to the Air Ministry, on the Imperial Airways air route to South Africa at Bulawayo and the Rand Airport, Germiston, and to various private owners. Some of the many advantages of steel construction for hangars and aerodrome buildings may be summarised as follows: — 1. Steel work provides a fireproof structure, and it is durable. 2. It is specially suited to adaptation and expansion, and can even be moved bodily from one position to another. 3. It permits radical alteration in internal planning with a minimum of expenditure. This applies to administration buildings as well as hangars. 4. Partitions can be erected which are easily removable and require a minimum of internal supports. 5. With steel construction it is possible to obtain the largest span with the least height, thus providing the minimum of obstruction to incoming and out going aircraft. 6. For the roofs and side coverings there is a choice of several kinds of material, for example, galvanised corrugated sheets, asbestos corrugated sheets, cor rugated " Cellactite " sheeting and Robertson's metal sheeting. A typical specification of a Boulton & Paul hangar pro vides for all the steel framework in the stanchions, roof trusses, purlins, rails, and wind bracing where considered necessary. For the roofing, 22-gauge galvanised corru gated sheeting is a favourite covering, and for the walls similar sheeting, but of 24 gauge, is used. The doors vary accord ing to the size and number of aircraft to be housed, and are of steel-framed design, covered with galvanised corrugated sheeting run on a top track with guides and guide rail at the bottom. With very high doors it is some times better for them to run on a bottom rail track with top guides. Lighting can be obtained by means of patent glazing or tee- bar putty glazing placed in the roof, or alternatively in the sides. When a building is erected in a tropical country, windows are often placed in the sides only in order to avoid the glare of light through roof glazing. Galvanised gutters and down- pipes of suitable section are always provided. All steelwork, other than galvanised material, is given one coat of paint before despatch. All bolts and nuts are sent for fixing, and in the event of customer preferring to under take the erection himself (which is not considered advisable), Boulton & Paul supply full
