JUNE 5, 1924 Two Views of the "Aero" Ae. 18. fitted with Siemens-Halske engine, but as this could not be obtained a 70 h.p. Anzani was fitted, with which the B.H. 5 performed very creditably. In a more recent form the machine is fitted with the new Czech Walter 60 h.p. engine. The main dimensions of the machine are :—Length o.a., 6-4 m, (21 ft.) ; span, 9-8 m. (32 ft. 2 ins.) ; wing area, 14 sq. m. (151 sq. ft.) ; weight emjptv, 320 kilos. (750 lbs.) ; weight loaded, 540 kilos. (1,190 lbs.)." With pilot and pas senger and fuel for 3 £ hours at full throttle the performance is as follows : Maximum speed, 155 km./h. (96 m.p.h.) ; climb to 2,000 m. (6,560 ft.) in 12 minutes. Ceiling, 5,000 m. ,(16,400 ft.). The B.H. 7 is a single-seater fighter with 300 h.p. Hispano- Suiza engine. It might be mentioned that the Hispano engines are now being manufactured under licence by the famous Skoda works. The machine is of the cantilever high- wing type, with the petrol tanks contained in the centre- section of the wing and giving direct gravity feed to the carburettors. The B.H. 7 is fitted with two synchronised Vickers guns, operated by a special " Avia " cam gear. The dimensions are :—Length o.a., 22 ft. 4 ins. ; span, 33 ft. 1 in. ; wing area, 193 sq. ft. The weight of the machine empty is 1,720 lbs., and the weight fully loaded is 2,400 lbs. Fuel for 2| hours' flying is carried, The maximum speed at ground level is 162 m.p.h. and the climb to 16,400 ft. occupies 11 minutes. The ceiling is 29,500 ft. Two examples of the " Avia " B.H. 9 are exhibited This machine is a two-seater intended for school work or sport ing flying. The engine is one of the five-cylinder radial air- cooled Walters. The machine is said to be very stable, but can, at the same time, be stunted to a considerable extent. Dual controls are provided, and the pupil, when the machine is being used for school work, occupies the front seat. The main dimensions of the B.H. 9 are :—Length o.a., 22 ft. 1 in. ; span, 32 ft. 3 ins. ; wing area, 146 sq. ft. The weight of the machine empty is 760 lbs., the useful load 460 lbs., and the total loaded weight is 1,220 lbs. The speed near the ground is 99 m.p.h., and the machine climbs to 2,000 m. (6,560 ft.) in 12 minutes. The ceiling is about 13,000 ft. A very similar but somewhat smaller machine, the B.H. 10, is also exhibited. This is to all intents and purposes a smaller " sister " of the B.H. 9. Its overall dimensions are smaller, it is a little faster, and is capable of all manner of stunts. In fact, the B.H. 10 is used extensively in the Czech flying service for teaching stunt flying. Like the B.H. 9, the B.H. 10 is fitted with 60 h.p. Walter engine. Its dimen sions are : length overall, 18 ft. 2 ins. ; span, 29 ft. 4 ins. ; wing area, 105 sq. ft. The weight of the machine empty is 637 lbs. and the useful load is 278 lbs., bringing the total loaded weight up to 915 lbs. The maximum speed near the ground is 102 m.p.h., and the machine climbs to 2,000 m. in 10 minutes. The ceiling is 15,000 ft. The B.H. 11 is a slight modification of the B.H. 9, and is used as a messenger 'plane in the Czecho-Slovak army. The main alteration is in the petrol tanks, which are somewhat larger and contain sufficient fuel for 4 hours' flying. The The "Avia " B.H.3.is a single-seater scout, fitted with the new Walter 220 h.p. engine. The radiator is placed under the fuselage. 360
