Description

Paraglider with inlet curtain. {Paraglider with inlet curtain.}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paraglider, and more particularly, to a paraglider having excellent cruise characteristics because the air discharged from the air chamber to the outside through the air inlet is reduced during flight.

Paragliders are one of the means of gliding through the air by generating lift using wind, and are mainly used for leisure sports for the leisure activities of many people living in a frustrating modern society. Since the paraglider has an intermediate characteristic of the gliding characteristic of the hang glider and the falling characteristic of the parachute, the paraglider has a high gliding capacity and also has high safety and is widely spread.

1 shows an example of a general paraglider, the conventional paraglider 1 is provided with a canopy 40 which is expanded by air inflow to generate a gliding lift, and is provided below the canopy 40. One end of the line 10 is arranged to maintain a row and row at regular intervals are connected, the other end of the line 10, the pilot repeatedly pulls the landing and landing of the paraglider 1 and adjusting means It is coupled to a pair of risers 20 to be used as a pair, respectively, is connected to the upper side of the harness 30, which serves as a cockpit seating the pilot, the rear of the canopy 40, the control means during the flight Control line 21 is used as is connected.

The canopy 40 includes an upper blade 41, a lower blade 42, and a diaphragm 43 inserted between the upper blade 41 and the lower blade 42. The upper blade 41 and the upper portion 43a of the diaphragm are sewn, and the lower blade 42 and the lower portion 43b of the diaphragm are sewn, thereby the upper blade 41, the lower blade 42, and the diaphragm ( 43) is formed. A plurality of diaphragms 43 are disposed at regular intervals between the upper blade 41 and the lower blade 42 to connect the upper blade 41 and the lower blade 42. A plurality of air chambers 44 are partitioned by the upper blades 41, the lower blades 42, and the plurality of diaphragms 43 to be formed inside the canopy 40, and the front end of the air chambers 44. The air inlet 45 is formed in the rectangular opening to enable the inflow of air. Therefore, when air flows through the air inlet 45 during the flight and the canopy 40 swells, the diaphragm 43 maintains a constant distance between the upper blade 41 and the lower blade 42. As a result, the overall aerodynamic shape of the canopy 40 is maintained.

However, in the conventional paraglider 1, when a pilot pulls the control line 21 during flight, air is discharged from the air chamber 44 through the air inlet 45 to the outside, or On the contrary, a situation in which air is introduced into the air chamber 44 through the air inlet 45 frequently occurs. When air is discharged to the outside through the air inlet 45, as illustrated in FIG. 2. Similarly, the vortex V is generated near the air inlet 45, and the vortic V causes variation in the flow of air, thereby reducing lift and increasing drag. As a result, there is a problem in that the lift and drag characteristics are temporarily lowered.

In addition, in the conventional paraglider 1, when the vortex V generated in the vicinity of the air inlet 45 is strong, there may be a problem that a serious safety accident due to a serious stall may occur.

The present invention has been made to solve the above problems, an object of the present invention is to provide a paraglider with an improved structure so that the air discharged to the outside through the air inlet from the air chamber during the flight can be reduced to have excellent cruise characteristics to be.
