Abstract

476,597. Aircraft having rotary-wing systems. NAGLER, B. June 12, 1936, No. 16473. Convention date, Feb. 8. [Class 4] A rotor-blade for aircraft includes a plurality of drawn tubular members arranged lengthwise of the blade and constituting load-supporting elements each member having a uniform profile throughout its entire length ; the members are secured together side by side to constitute the blade structure. As shown, a wing is built of drawn chromium-molybdenum steel tubes 1, 2, 3 interconnected by spot welding, apertures 8.11 being provided for introduction of the electrodes. A covering surrounds the tubes. A stepped profile may be formed of tubes of different widths placed end to end and secured to a continuous tube. The adjoining faces of the tubes 1, 2 may lie in a longitudinal plane passing through the centre of gravity of the blades. The profiles of the tubes may be chosen so that a plane passing through the centre of gravity of the wing sections contains the centre of lift. The outer end of the blade may be closed by a cap and a split root mounting 12 is secured by rivets. Specification 458,312 is referred to.
