The Lehtovaara PIK-16 Vasama (English: Arrow) is a Finnish mid-wing, single-seat, FAI Standard Class glider that was designed by Tuomo Tervo, Jorma Jalkanen and Kurt Hedstrom, who were students at the Polyteknikkojen Ilmailukerho (PIK) and produced by Lehtovaara. [1] [2]
The PIK-16 is constructed from wood, with a fibreglass nose. The 15.0 m (49.2 ft) span wing employs a Wortmann FX-05-168 (14% modification) airfoil at the wing root, transitioning to a NACA 63 (2)-165 at the wing tip. The wing features dive brakes. [1] [2] [3] The prototype Vasama had V tail, but it was changed to cruciform tail on production aircraft.
A total of 56 PIK-16s were built. The aircraft was not type certified but it did become the second most exported Finnish glider, surpassed only by the later PIK-20 series. [1] [2] [4]
The prototype PIK-16 set a Finnish national record for a 300 km (186 mi) triangle course of 86.6 km/h (54 mph) before it had even finished flight testing. [5]
The design won the OSTIV prize at the World Gliding Championships held at Junín, Buenos Aires Province, Argentina in 1963, finishing third in the standard class. [1] [2]
