An oscillating turret is a form of turret for armoured fighting vehicles, both tanks and armoured cars. The turret is unusual in being made of two hinged parts. Both elevation and recoil rely on the upper part of the turret moving relative to the lower part. Oscillating turrets have only rarely been used. Their only widespread use was on two French designs, the AMX-13 light tank and the Panhard EBR armoured car. Both of these used the advantages of the oscillating turret to mount a relatively heavy gun on a lightweight chassis. == Design == The turret consists of upper and lower parts, joined by a trunnion. The gap between these two parts is covered by a distinctively visible rubber or canvas bellows. The gun itself is fixed rigidly to the upper part of the turret. Elevation of the gun, i.e. aiming for range, is achieved by tilting the entire upper part of the turret. Traverse is achieved conventionally, by rotating the turret. Since the gun barrel is attached rigidly to the turret, the entire upper part of the turret recoils when fired. There is no mantlet as such and the barrel and breech retain their position in the upper turret. Recoil energy is absorbed by the usual oleo-pneumatic dampers, but these are integrated with the hydraulic actuators which position the oscillating portion of the turret, rather than linearly alongside the gun. 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「Oscillating turret」の詳細全文を読む スポンサード リンク
