Abstract

100,455. Antoni, G., and Antoni, U. May 12, 1915, [Convention date]. Planes, arrangement and construction of.-The wings of aeroplanes have flexible ribs so that the camber can be varied. Fig. 1 shows fexible upper and lower members a, b secured to a distancepiece 0 at the front end and passed through stirrup-shaped brackets d on the centre spar. A hotels made in the front end of each rib to take the front spar la, Fig. 5, the vertical sides of the hole being curved outwardly at the lower front end and at the upper rear end to permit of the rib being turned into the position shown in dotted lines. The upper and lower edges of the hole are made convex inwards. Angles f secured to the spar prevent lateral movement of the ribs. Either or both of the members t, b are tapered in thickness from the centre spar towards either or both ends, but in another form the parts between the front and centre spars are of uniform thickness and the rear parts tapered in thickness. To form a rigid foundation for the wing, the front and centre spars are connected together by struts i, shown in section in Fig. 7, and cross-braced. Saddlepieces p embracing the spars have each a tailpiece q and two extensions s for the attachment of the external stay wires.
