Description

Technical Field

[0001] The invention belongs to the technical field of airborne airdrop, and in particular, is a spring-guided parachute suitable for tandem skydiving. Background Art

[0002] For the main and backup integrated parachute bag, the main parachute and the backup parachute are packed in the main parachute compartment and the backup parachute compartment behind the skydiver respectively. For the main parachute, the process of "parachute bag opening - canopy inflation" can be realized by the parachute opening rope. The backup parachute is a backup equipment for dealing with special situations in the air. After the backup parachute is opened in the air, it is difficult for the canopy of the backup parachute to independently complete the opening procedure of "canopy lifted out of the parachute bag - canopy pulled out of the canopy cover - canopy inflation" due to the influence of the vortex zone on the back of the human body.

[0003] For split parachute packs, the main parachute is on the back and the backup parachute is on the chest. When a skydiver encounters an emergency in the air, he can manually open the backup parachute pack, pull out the canopy, and assist in inflating it. However, for a main and backup integrated parachute pack, the skydiver cannot assist in inflating the backup parachute, and the reliability of the backup parachute inflation cannot be guaranteed due to the influence of the vortex zone behind him. Summary of the invention

[0004] The object of the present invention is to provide a spring-guided parachute suitable for tandem skydiving.

[0005] The technical solution to achieve the purpose of the present invention is: a spring-guided parachute suitable for tandem parachuting, comprising: a canopy top width, a canopy circumference width, parachute ropes, a conical spring frame, a rope ring and a main part of the top of the parachute; the conical spring frame is covered with the canopy and the parachute ropes;

[0006] The conical spring frame is the basic frame of the spring-guided umbrella. A section of the conical spring frame with a larger diameter is sewn to the main part of the umbrella top, and the top width of the canopy is sewn to the main part of the umbrella top along the circumferential direction. The canopy circumference and the canopy top width are spliced ​​and extend to a section of the conical spring frame with a smaller diameter. The parachute rope takes root at the outer edge of the circumference of the main part of the umbrella top, is sewn downward to the canopy, and finally converges at the bottom of the spring frame to form a rope ring.

[0007] Furthermore, the canopy top sheet is composed of 4 to 8 canopy sheets, a single canopy sheet is fan-shaped, the upper end of the canopy top sheet is sewn in sequence along the circumferential direction of the main part of the umbrella top, and the lower end is sewn together with the canopy circumference; the canopy top sheet is made of brocade silk cloth.

[0008] Furthermore, the single piece of the canopy width is fan-shaped, and the number is consistent with the canopy top width; the canopy width is made of mesh yarn.

[0009] Furthermore, the upper end of the parachute rope is sewn to the main part of the umbrella top, and is sewn downwards in sequence to the top width of the umbrella canopy and the surrounding width of the umbrella canopy, and finally converges at the lower end of the guide umbrella to form a rope ring; the parachute rope uses brocade ribbon as material.

[0010] Furthermore, the conical spring skeleton is in a spiral shape, and the diameter of the spring gradually decreases from top to bottom, and the spring of the upper circle just covers the spring of the lower circle.

[0011] Furthermore, the main part of the umbrella top is in the shape of a disc, fixing the conical spring frame, the top width of the umbrella canopy and the umbrella rope; the main part of the umbrella top uses a polyethylene plate as a material.

[0012] Compared with the prior art, the present invention has significant advantages: the spring-guided parachute of the present invention can get rid of the influence of the vortex zone behind the skydiver, and can assist in inflating the backup parachute, thereby improving the reliability of opening and inflating the backup parachute of the main-backup integrated parachute bag.

[0014] Figure 2 It is a conical spring skeleton.

[0015] Figure 3 It is the top piece of the canopy (single-piece canopy piece).

[0017] The present invention designs a new type of guide parachute, which uses the elastic force of its own frame to eject the entire guide parachute out of the vortex area behind the skydiver at the moment the backup parachute is opened, and after the guide parachute is hit by the airflow, the aerodynamic resistance is used to pull the entire backup parachute out of the parachute bag, and assist the canopy to realize the parachute opening and inflation procedures.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Combination Figure 1 The new spring-guided umbrella of the present invention comprises: an umbrella top sheet 1, two umbrella surrounding sheets, an umbrella rope 3, a conical spring frame 4, a rope ring 5 and an umbrella top main part 6.

[0020] Canopy top panel 1: combined Figure 3 The canopy top sheet 1 is generally made of brocade silk cloth with low air permeability, and is the main component of the spring-guided umbrella to generate aerodynamic resistance. The canopy top sheet 1 is generally composed of 4 to 8 canopy sheets, and a single canopy sheet is fan-shaped. The upper end of the canopy top sheet 1 is sewn in sequence along the circumferential direction of the umbrella top main part 6, and the lower end is sewn together with the canopy circumference 2.

[0021] Canopy Width 2: Combined Figure 4The canopy circumference 2 is generally made of mesh with a high air permeability, and the airflow can pass through the circumference and interact with the top circumference. The single circumference is generally fan-shaped, and the number is the same as the top circumference.

[0022] Umbrella rope 3: Umbrella rope 3 generally uses high-strength brocade ribbon. The upper end of the parachute rope 3 is sewn to the main part 6 of the umbrella top, and is sewn downward to the top width 1 of the umbrella canopy and the surrounding width 2 of the umbrella canopy in turn, and finally converges at the lower end of the guide umbrella to form a rope ring 5.

[0023] Conical spring skeleton 4: Combination Figure 2 The spring bones are spiral, and the spring diameter gradually decreases from top to bottom. The upper spring just covers the lower spring. Its function is to release the compressed elastic force at the moment the parachute bag is opened, and guide the parachute to bounce away from the vortex area.

[0024] Rope ring 5: The function of rope ring 5 is to connect the guide parachute connecting rope and transfer the aerodynamic resistance of the guide parachute to the main parachute or the backup parachute through the guide parachute connecting rope.

[0025] Umbrella top main part 6: The umbrella top main part 6 is disc-shaped and generally made of a polyethylene sheet with a certain hardness. Its function is to fix the conical spring frame 4, the canopy top width 1 and the umbrella rope 3.

[0026] The working process of the spring-guided umbrella can be divided into two stages: the preparation stage and the working stage.

[0027] Preparation stage: compress the spring-guided parachute completely and seal it in the parachute bag.

[0028] Working phase: After the skydiver opens the parachute bag in the air, the spring-guided parachute relies on its own elastic force to bounce away from the vortex area. At the moment of contact with the airflow, the spring-guided parachute completes inflation and generates a certain aerodynamic resistance. Then the entire parachute canopy is pulled out of the parachute bag through the guiding parachute connecting rope to complete the subsequent parachute opening procedure.

[0029] Advantages of spring-guided parachute: As a new type of guide parachute, the spring-guided parachute can bounce away from the vortex area after the parachute bag is opened, relying on its own elastic characteristics, avoiding the influence of turbulence on the inflation of the parachute canopy and better playing a traction role on the main parachute.

[0030] The present invention has been fully verified through ground packaging tests, ground elastic force tests and air parachute opening tests, and can realize the function of assisting the opening of the reserve parachute and can effectively avoid the influence of the eddy current zone on the parachute opening process.
