JANUARY 16, 1936. FLIGHT. &3 A 254 m.p.h. Fast New Tzvin-engined Ten-seater Construction All-metal A1 the suggestion of Luft Hansa, the German Heinkel factory has re cently completed a n d flight-tested a twin - engined high-speed commercial mono plane based upon the Heinkel He.70. The He.70, which is a single-engined four-passenger monoplane, has a top speed of 234 m.p.h. In its final form the two-engined newcomer, carry ing ten passengers, is expected to attain a top speed of ovtr 254 m.p.h. Actually, that is the projected speed with two 880 h.p. engines ; the machine at present in existence has two 660 h.p. water-cooled and geared B.M.W.s (twelve-cylin der vee), and these give a maximum of 214.37 a cruising speed of 186.41 m.p.h. The new machine is notable as Dr. Heinkel's first all- metal production ; hitherto he has shown a preference for mixed construction. A cantilever low-wing monoplane, it is of extremely clean aerodynamic form, the fuselage being of the mono- coque type, and a smooth metal covering being employed for all surfaces. The nose of the fuselage forms a luggage, mail, or freight m.p.h. and With its present 660 h.p. engines the new Heinkel has a top speed of 214.37 m.p.h. ; Over 254 m.p.h. is expected when the 880 h.p. units are fitted. compartment; then comes the pilots' compartment, which appears to give a reasonably good outlook, and behind it is a surprisingly spacious passenger cabin which seats ten. It is sub-divided into two compartments, the forward one accommodating four passengers who may wish to smoke, and the rear section the remainder. The windows are of the usual small type which monocoque construction makes necessary. In addition to the passenger load, 200 kg. (441 lb.) of mail or freight can be carried. Like the wing, the control surfaces are of all-metal in ternal construction, with a duralumin covering. The elevators have trimming tabs, and the wings are flapped. Fitted with hydraulic shock-absorbers, the under carriages retract into the engine nacelles, and the tail wheel is also retractable. The two water-cooled and geared 660 h.p. B.M.W. engines drive Hamilton Standard variable-pitch air-screws. Dimensions and Performance Principal data are as follows: — Span, 74 ft. 1 in. (22,6 m)\ length, 56 ft. 1 in. (17,1 m); height, 12 it. 6 in. (5,0 m); wing area, 942.92 sq. ft. (<?7,6 m2); tare weight, 11,442.02 lb. 5100 kg.); gross weight, 16,755.1 lb. (7 boo kg.); dis posable load, 5,313.08 lb. 2410 kg.); wing loading, 17.8 lb./sq. ft.; power loading, 12.65 Ib./h.p.; top speed, 214.374 m.p.h. (_?45 km./hr.); cruising speed, 186.412 m.p.h. (300 km./hr.); land ing speed, 62 m.p.h. (100 km./hr.); climb to 1,000 m, 3 min.; normal range, 932 miles (1 500 km). As stated above, the new Heinkel is shortly to be fitted with two 880 h.p. engines—presumably B.M.W.s—when the maximum speed will be increased, it is expected, to 254 m.p.h., and the cruising speed to about 217 m.p.h. It is expected that several will be in sendee with D.L.H. by midsummer. The "non-smoking " section of the cabin. Five Million Pounds in the Air DURING 1935 no fewer than 115 new companies were formed to carry on aeronautical business of various kinds. They comprised 13 public companies, with capital totalling £3,298,100, and 102 private concerns with capital totalling £1,823,190. The grand total was 115 companies, capitalised to the extent of ^5,121,290, and this sum comes sixth in a list of forty-eight classes of industry. These figures are according to the annual analysis published by Jordan and Sons, Ltd., company registration agents, of Chancery Lane, London.
