Design and development

The A-15 was a follow-on design, based on the bureau's experience gained with the A-11 and A-13 gliders. This new open class design quickly proved its worth as a record-setter.[1]

The aircraft is made from aluminium. Unusually for a Cold War Soviet aircraft, its 17 m (55.8 ft) span wing employs an American NACA 64-618 airfoil at the wing root, transitioning to an NACA 64-616 section at the wingtip. The A-15 carries 50 kg (110 lb) of water ballast. The landing gear is a retractable monowheel.[1][2]

A total of 350 A-15s were built.[1]

Operational history

The A-15 was used to set many world records, including a world goal distance record of 714.023 km (444 mi), flown in June 1960.[1]

In August 2011, there was one A-15 registered with the Federal Aviation Administration in the United States.[3]
