Built in Germany in 1971, it made several flights but did not enter production. ==Design and development== One of the main reasons for the popularity of the biplane in the early days of aviation was the wing strength provided by this arrangement. The two wings, their interplane struts and flying wires form a strong, box girder-like structure. Thus cantilever biplane wings are quite rare, though they do provide extra wing area for a given span and for the easy separation of wings from each other and from the fuselage. The Lemberger LD20b was one of this kind, designed with readily detachable wings and tailplane so that it could be towed by a car. Whilst towing, the wings were stowed alongside the fuselage. The tailskid was linked to the car via a luggage rack-like frame.〔 The upper and lower wings of the LD20b were very similar, with the same span, area and straight, near-constant chord, plan. The lower wings were attached to the lower fuselage longerons and the upper ones to cabane struts above the front of the cabin. They were arranged with considerable stagger. The wings were built around two closely spaced spars, with plywood skin from the rear spar forward forming a torsion box and fabric covering behind. Differential ailerons were mounted only on the lower wings.〔 The wooden, rectangular fuselage was plywood-covered to just behind the pilot's seat and fabric-covered further aft apart from a curved plywood decking behind the cabin. The fin was integral with the fuselage and unusually shallow with the variable incidence tailplane mounted on top of it, a little above the fuselage and bearing damped〔 elevators. The balanced rudder was much taller than the fin. The enclosed cabin seated two in tandem with the front seat under the upper wing and over the centre of gravity. Dual control was fitted. In front, a Walter Mikron inverted 4-cylinder engine drove a two-bladed propeller.〔 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「Lemberger LD20b」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.
