334 FLIGHT. MARCH 30, 1930 HERE AND THERE (CONTINUED) spruce centre. Over a few feet at each^ wing-tip the spar is without the stiffening, so that any damage at this point can easily be repaired by splicing. The robust centre section of this spar is carried between two fuselage bulkheads, while the rear spar is similarly mounted. Aft of the girder-braced forward section the rest of the fuselage is a plywood box. The object in laying out the machine as a mid-wing mono plane is to provide, as far as possible, the advantages both of the high-wing and low-wing type. With this arrangement the low-wing range of view is available, while most of the stability characteristics of the high-wing machines are re tained. In its prototype form the Helvellyn will be fitted with a conventional undercarriage, but the fuselage members are so spaced that it will be a simple matter to move the whole undercarriage rearwards and to fit a nose-wheel, for which provision has been made in the forward structure. The engine will be a Cirrus Minor of 80-00 h.p., and it is estimated that the maximum speed will be 127 m.p.h. and the normal cruising speed no m.p.h. With the split flaps down, the stalling speed will be in the region of 45 m.p.h. Other essential figures are: Span, 33ft.; length, 22ft.; weight empty, 895 lb.; all-up weight (fully aerobatic), 1,500 lb.; wing loading, 9.6 lb. per sq. ft.; initial climb, 750ft. per min.; service ceiling, 13,000ft.; and range at cruising speed, 660 miles. Meanwhile considerable developments and extensions are being made in the airscrew section of the Hillson factory, where work is being carried out under Jablonsky patents. One of the latest ideas in this section is the application of one-piece brass leading edges. Brass strips are attached to each side of the leading edge, and the one-piece cover is simply sweated on to these strips. Nowadays, of course, with the greater use of constant-speed and other hubs, there is a growing demand for single blades with very specially strengthened roots. The difficulty is to make this compara tively small-diameter root strong enough in such a way that it can be firmly fitted into the hub. The increased know ledge of the capabilities of special types of " artificial " wood is now making things easier for the airscrew designer. Direct Club Subsidy in India AFTER the end of this month the scheme for the granting of subsidies to the Indian flying clubs, which has been in action for three years, will no longer be operative. The Government of India has, however, decided to renew the grants for a further period of three years with special conditions de signed to improve the financial positions of the clubs and to reduce the cost of flying. For a start, seven fully equipped D.H. Tiger Moths will be purchased and loaned to the seven subsidised clubs. A portion of the bonus grants which have hitherto been paid direct to the clubs will, in future, be paid to the pilots and the maxi mum grants which may be earned by each club will be increased from Rs.20,000 to Rs.25,000. The fixed annual sub sidy will be dependent on the number of types of machines maintained by the clubs. The machines will be divided into three classes, depending on the power and obsolescence or otherwise of the machines. These classes will be designated "A," "B " and "C," the last comprising the types which are generally known as the ultra-lights. The bonus rates will remain unchanged, but of the Rs.300 for each ab initio "A," Rs.ioo will go to the pilot, while of the Rs.ioo for each renewal a sum of Rs.50 will go to the pilot. It is reasonably supposed that the loss to the flying clubs by the payment of part of the bonuses to the pilots themselves will be more than set off by the increase in fixed subsidy and by the resultant increase in the number of pilots being trained. Another Australian Factory "pHE CLYDE ENGINEERING CO., LTD., one of the largest -*- machinery factories in Sydney, has announced its inten tion of erecting a factory for the construction of military and civil aeroplanes and has signed an agreement with the Aircraft Development Pty., Ltd., which represents in Australia the interests of the Armstrong Siddeley Motors, Ltd., Airspeed (1934), Ltd., Phillips and Powis Aircraft Co. and the Heston Aircraft Co. These four companies will grant licences to the Clyde Engineering Co., Ltd., for the erection of various types of machines in the latter's own aircraft division. Various other Australian companies, which produce precision apparatus, have offered their support. A special test aerodrome will also be laid out. In the last ten years, the Clyde Engineering Company has produced many types of transport material, including loco motives, railway carriages and other rolling stock, tramcars, engines and bridges. The general director of the company is Mr. H. P. Weymouth. The chairman of the Aircraft Develop ment Pty., Ltd., is Mr. Stuart F. Doyle. To date, the only Australian aircraft construction company has been the Com monwealth Aircraft Corporation, Ltd., of Fishermen's Bend near Melbourne. New Club Near London A NEW flying club has been formed on the outskirts ol South-East London, its aerodrome lying within 17 miles of Charing Cross. Though its name—the Horton Kirby Flying Club—suggests the moors of Yorkshire or the Lakeland Fells, it is actually called after the nearby village of Horton Kirby, which lies to the east of the Dartford-Farningham road, at a point south ol Farningham Road station. By road, the aerodrome c&n best be reached via the main London-Maidstone Road, turning left after passing the Farningham Hotel on the Farningham By-pass. The club possesses a fleet of nine training aircraft, including six Gipsy 1 Moths, one B.A. Swallow with a Cirrus Minoi engine and two Cirrus-engined Avians. Mr. G. W. Alexander, who was chief pilot of Air Dispatch. Ltd., is the chief instructor. His right-hand man is Fit. Lt. P. de C. Festing-Smith, and there are three assistant in structors. The fee for full membership is two guineas, with an entrance fee of one guinea. Associate members will pay one guinea per annum, with no entrance fee. The flying rates are as follows: Solo, 30s. per hour; dual, £2; blind flying. £2 10s.; for C.A.G. members a subscription of 2s. 6d. will be charged, while 5s. per hour will be the rates for both dual and solo flying. Full courses for " B " licences can be arranged at an inclusive charge or on contract rates. While large numbers of C.A.G. members have already joined the club, there are still vacancies for those living in or near South-east London. Further details are obtainable from the secretary, Mr. D. S. Alexander, of the Aerodrome, Horton Kirby, near Dartford, Kent. Sat. 15th. Thurs., 20th. Fri., Sat. Thurs. Sun. Tues., Sat., 21st. 22nd. 4th. 14th 16th * 20th. Forthcoming Events APRIL.
