FLIGHT, SEPTEMBER 9, 1932 THE NEW HEINKEL HE 64 By EDWIN P. A. HEINZE ONE of the financially soundest aeroplane factories in Ger many, and one of the busiest, too, is that of Heinkel at Warnemunde, on the shores of the Baltic. Yet this maker is relatively less known to the general public than most of the others, because he neither builds transport planes of a type used in Germany nor, up to the present, small planes such as the clubs and individual owners would purchase. The factory has specialised more in the production of school machines and catapult planes, and has occupied itself most extensively with the design of military planes for foreign powers. Hence it created a sensation when one day news leaked out that Heinkel was entering the light plane field, and that he intended taking part in this year's International Light Plane Competition on the Continent. The fine perform ance of the German officer Seidemann, with his colleague Witt as observer, in an Argus-powered Heinkel, during the air tour forming part of this competition Heinkel into the limelight of public interest. Indeed, the new Heinkel machine appears to be what may be termed a " hit," which is all the more remarkable as this is the first machine of this type developed by the company that was founded in 1922 by Dr. Ernst Heinkel, already then an aircraft engineer of long standing, who for years had been the technical chief of other aeroplane factories in Germany, especially during the War. The new Heinkel is a low wing cantilever monoplane built entirely of wood, with a long and slender fuselage of oval section, with which the wing stubs are integrally formed. The single spar wings are of trapezoid contour and are secured by universal joints and lever-operated " EINE HEKN) giving a take-off brought KLE SACHE ": Capt.

The connection is so well worked that the small gap between the wings and stub wings barely measures one millimetre, so a special covering strip is not required. The bolt lever, however, permanently protrudes slightly on the lower wing surface. The maximum chord of the wing at the roots is 2 metres (6.56 ft.), and 0.8 metre (2.62 ft.) at the rounded tips. The wings are set at a dihedral angle of 4\ degrees, and have a span of 9.8 metres (32.15 ft.). The over-all length of the machine, which has two seats arranged one behind the other, is 8.31 m. (27.26 ft.) and the greatest beam (i.e., horizontal diameter) of the fuselage 0.73 m. (2.4 ft.). The wings are provided with slow-flying flaps and ailerons extending to and partially completing the rounded " GOOD BYE TO RADLETT : The three Heinkels leave in formation after their demonstrations.
