It had a simple structure, box fuselage, strutted high wing and low performance typical for the primary type of training glider. The LPŻ held a competition in 1955 for the design of a new primary style single-seat trainer, which was won in March 1955 by the design by Tadeusz Grudzieński, named X-11.〔Krzyżan, Marian, ''Samoloty w muzeach polskich'' (in the Polish museums ), Warsaw: Wydawnictwa Komunikacji i Łączności, 1983, ISBN 978-83-206-0432-0, p. 140〕 The prototype glider was constructed in the SZD in Bielsko by Władysław Okarmus, and designated SZD-18. Flight trials began on 30 November 1956 (pilot Adam Zientek) proving, that the SZD-18 had good handling qualities and performance adequate for its intended role. It was regarded as one of the best gliders in its class〔 Babiejczuk, Janusz and Grzegorzewski, Jerzy. ''Polski przemysł lotniczy 1945-1973'' (Polish aerospace industry 1945-197). Warsaw: Wydawnictwo MON, 1974, p. 123〕 and the Polish best training glider.〔 However, the aero clubs, now independent of the LPŻ, rejected the single-seat training concept, moving towards the more conventional two-seat pupil/instructor method, which had been proven to be quicker, more efficient and safer. No production was carried out and the sole prototype (SP-1640) flew as a club glider with the Warsaw aero club until 1966, when it was given to the Polish Aviation Museum in Kraków.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SZD-18 Czajka」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
