[0003] This method of parachute recovery cannot be applied to the horizontal recovery of the full arrow. The horizontal recovery of the full arrow requires that the opening direction of the parachute be in the normal direction of the horizontal axis of the full arrow and act on the center of mass of the full arrow.
However, when the rocket cannot meet the position of the center of mass to install the parachute system and has a certain flight speed, a parachute connection mechanism is needed to realize the horizontal recovery of the entire rocket

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.
Description
technical field [0001] The present disclosure relates to the technical field of aerospace vehicle parachute recovery, in particular to a space vehicle parachute connection mechanism. Background technique [0002] At present, the parachute recovery method on aerospace vehicles is mostly used in cabin-level recovery. The parachute system is installed in the direction of the axis of the cabin, and the main parachute is dragged along the axis of the cabin (or parachute) to reach the height of the parachute. Open the parachute to realize the cabin-level vertical landing recovery. [0003] This method of parachute recovery cannot be applied to the horizontal recovery of the full arrow. The horizontal recovery of the full arrow requires that the opening direction of the parachute be in the normal direction of the horizontal axis of the full arrow and act on the position of the center of mass of the full arrow. However, when the rocket cannot meet the position of the center of mass...
