SZD-38 Jantar 1
The SZD-38 Jantar 1 (Amber) is a glider designed and produced in Poland from 1971.
==Development==
After SZD's success in designing high performance all wood gliders, the design group's first product using Fibreglass composite materials emerged as a very competitive glider.
Two prototypes of the SZD-37x Jantar were built (SP-2636 and SP-2637), using fibreglass reinforced plastic fuselage and tail-unit with an aluminium alloy tubular tail boom, SP-2636 was built with a 17.5m span wing and SP-2637 a 19m span wing. The first flight of SP-2636 was carried out on 14 February 1972 and extensive testing carried out before the second prototype, SP-2637 (first flight 13 May 1972), was entered in the 1972 World Gliding Championships at VrŠac in Yugoslavia, taking the first place in the newly established 19m Class and the 3rd in the Open Class, flown by St. Kluk.〔http://www.ssa.org/usteam/adobe%20pdf/1972%20WGC〕
Production of the 19m span Jantar commenced as the SZD-38 Jantar 1 in 1973 with 57 built by 1975, 24 for export. The success of the SZD-37x prototypes in the World Championships was not repeated, due partly to shrinkage of the epoxy resin causing irregularities in the wing surfaces, and partly to the improved performance of the competing aircraft. The SZD-38 broke seven Polish National records in 1973, but was soon out-classed in competitions. The standard instrument fit included Variometer, Turn and Bank, Compass as well as standard ASI, Altimeter etc.. Provision was also made for an Artificial Horizon and oxygen equipment.
