The invention provides an aerospace craft parachute landing connecting mechanism. The parachute landing connecting mechanism comprises a fixing part and a separating part. The fixing part comprises anunlocking bolt, and the unlocking bolt is an explosive bolt. A collection box is connected to the aircraft, one end of the unlocking bolt is arranged in the collection box, and the other end extendsout of the collection box. The exterior of the unlocking bolt is sleeved with an anti-shearing sleeve. The anti-shearing sleeve is clamped in the mounting block, and the end of the unlocking bolt extends out of the mounting block. The separating part comprises a lifting point support, the end, extending out of the mounting block, of the unlocking bolt is fixed on the lifting point support, and anexplosion separation point of the unlocking bolt is arranged between the mounting block and the lifting point support. A brake parachute cord and a main parachute cord are respectively hinged to a conversion hinge. The conversion hinge is connected with the lifting point support through a hinge lug. The mechanism has the beneficial effects that after the unlocking bolt is exploded, the unlocking bolt between the fixing part and the separating part is broken, so that the fixing part is separated from the separating part, the brake parachute and the main parachute are opened in sequence, and horizontal recovery of the whole rocket is achieved.
本申请提供一种航天飞行器伞降连接机构,包括固定部与分离部;固定部包括解锁螺栓,解锁螺栓为爆炸螺栓;收集盒连接在飞行器上,解锁螺栓的一端设置在收集盒内,另一端伸出收集盒;解锁螺栓的外部套设抗剪套筒;抗剪套筒卡接在安装块内,解锁螺栓的端部伸出安装块;分离部包括吊点支座,伸出安装块的解锁螺栓的一端固定在吊点支座上,解锁螺栓的爆炸分离点设置在安装块与吊点支座之间;转换铰链上分别铰接连接减速伞伞绳和主伞伞绳;转换铰链通过铰链耳片与吊点支座连接。本申请的有益效果是:解锁螺栓爆炸后固定部与分离部之间的解锁螺栓断裂使得固定部与分离部分离,使得减速伞以及主伞依次打开,以达到全箭水平回收。
