Embodiment 1

[0020] see figure 1 -2. The present invention provides a parachute with a pre-expansion device. For example, this parachute with pre-expansion device can include: canopy 6, its bottom edge is provided with connecting rope 8; Pre-expansion device, it includes four main poles 2, four inner poles 1 and eight Auxiliary struts 3, four main struts 2 and four inner struts 1 are connected at intervals to form an octagonal structure, and two of the main struts 2 are arranged horizontally, and the other two main struts 2 are vertical The two ends of the main strut 2 in the extension direction of the main strut 2 are respectively connected to one of the auxiliary struts 3, and the eight auxiliary struts 3 are connected with the four main struts. 2 are connected to form a quadrilateral structure, and the connecting rope 8 is connected to the main pole 2 and the inner pole 1.

[0021] Preferably, the main pole 2 and the inner pole 1 are detachably connected.

[0022] Preferably, the mai...

Abstract

The invention discloses a parachute with a pretensioning device. The parachute comprises a canopy and the pretensioning device, wherein connection ropes are arranged at the bottom edge of the canopy; the pretensioning device comprises four main supporting rods, four inner supporting rods and eight auxiliary supporting rods; the four main supporting rods and the four inner supporting rods are connected at intervals to form an octagonal structure; two of the main supporting rods are horizontally arranged, and the other two main supporting rods are vertically arranged; each of two ends of each main supporting rod in the extending direction of the corresponding main supporting rod is outwardly connected with each auxiliary supporting rod; the eight auxiliary supporting rods and the four main supporting rods are connected to form a quadrangular structure; the connection ropes are connected with the main supporting rods and the inner supporting rods. According to the parachute, the air intake of the parachute can be increased, so that the parachute can be quickly tensioned, and the drop loss height can be reduced; therefore, the parachute obtains enough stable time, and the directions of an air inlet and an exhaust opening during canopy inflating can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of parachutes, in particular to a parachute with a pre-expansion device. Background technique [0002] With the development of parachute technology and the enrichment of test methods, higher requirements have been put forward for the parachute horizontal speed and vertical falling speed tests, mainly reflected in: the accuracy of test data; the repeatability of test data; the efficiency of the test . The parachute horizontal speed test is more detailed in the US military standard: "The horizontal speed should be dropped from a fixed position (such as an umbrella tower) when the parachute is dropped, and the fixed position should have a sufficient height to ensure a stable landing time of at least 10 seconds." In addition, there are relatively strict requirements for specific environmental parameters, test times, test intervals, parachute release status, and upwind and downwind releases, because the above fa...
