Title
(EN) Double door thurst reverser assembly
(ZH) 双门式推力换向器装置
Abstract
(EN)
A pivoting door type thrust reverser assembly for a dual flow engine is described, which includes a fixed cowling construction with a front body portion (9) and a rear body portion (12) joined by longitudinal beams (10, 11) and defining reversal chambers in each of which a door (7) is pivotably received. The door pivot pins (17) are carried by two pairs of chords (15, 16) such that the pivot pins are spaced from the engine axis X-X'. This arrangement provides for an efficient deviation of the cold flow and for the maximum opening of the doors.

(ZH)

一种用在双流式喷气发动机上的绕枢轴转动双门式推力换向器装置,它包括一个由纵梁(10,11)连接起来的前体部分(9)和后体部分(12)共同构成的固定整流罩(5),在其上形成了换向室,在每一个换向室中容纳了可绕枢轴转动的门(7)。门枢轴轴销(17)由两对支杆(15,16)支承着,于是轴销就与发动机轴线(X-X′)分离开一段距离。这种布置提供了对冷气流的有效偏转和双门的最大开度。
