M.Hardy. Gliders & Sailplanes of the world

Zauner OZ-5

  This single-seater sailplane was designed and built to Standard Class specifications by Otto Zauner of Vineland, New Jersey, who had previously built from kits and/or plans a Schweizer SGS 1-26, a Briegleb BG 12, a Bryan HP-14 ДальшеMore>>> and a Thorpe T-18 ultra-light. The OZ-5's fuselage and tail unit are of Mr Zauner's own design but the wings of a Bryan HP-15 are fitted in the shoulder position. The forward fuselage and cockpit tapers to a slim boom carrying the tail, the former being of glassfibre construction to about one-third back along the tail boom; the rest of the boom and the cantilever T-tail are all-metal, the fin and rudder being swept back. There is a retractable monowheel and the pilot sits under a one-piece flush-fitting cockpit canopy. The wings are the same structurally as the HP-15 and of high aspect ratio; they are two-spar all-metal structures with metal skinning and plastic leading edges, and only three ribs in each wing, the spaces between the ribs being filled with plastic foam. Metal fixed hinge flaps are fitted, the ailerons drooping in conjunction with them. Flight testing of the OZ-5 began in 1975.
