Since it has the same structure as the spoiler 37, its explanation will be omitted, but by operating the control cable 43 connected to the rear of the elevator 42, the entire wing body can be directed up or down. .

Note that the aileron 32, spoiler 37, and elevator 42, which are examples of vertically movable small wings, are approximately parallel to the main wing 22 due to wind resistance in a natural gliding state, and the wind resistance is increased by pulling the control cable. It is.

Furthermore, a flap (not shown), which is an example of a vertically movable wing, may be attached to the rear part of the main wing 22 and inside the aileron 32, or a slat (not shown) may be attached to the front part of the main wing 22. It is possible.

Next, the method of using the ram pressure type paraglider 20 with small wings and its operation will be explained in detail.

First, when the front part of the ram-pressure small-winged paraglider 20 is turned in the direction of the wind with the harness 26 attached, air flows through the opening 27 at the front part of the bag body 21 and through the air introduction pipe 28. It enters the inside of the bag 21 and is further introduced with the fuselage 23, vertical tail 29, and horizontal tail 30 to form a wing body.

Accordingly, a string can be attached to the harness 26 of the ram-pressure winged paraglider 20 and pulled, or the end of a predetermined length of string attached to the harness 26 can be fixed to the main wing 22 and horizontal stabilizer 30. When exposed to the wind, the ram-pressure small-winged paraglider 20 rises due to the principle of a kite, but
Since the tip of the main wing 22 has a streamlined shape as a whole, lift is increased by reducing wind resistance.

Then, when you remove the string connected to the lower harness 26,
The ram-pressure winged paraglider 20 will glide.

Here, the aileron 32, spoiler 37, and elevator 42 are freely operated to perform maneuvers such as elevation, descent, deceleration, etc., but since these are composed of a pouch body independent of the wing body, the wing body Next, a ram-pressure small-winged paraglider according to another embodiment of the present invention shown in FIGS. 3 and 4 has improved maneuverability and stability without substantially deforming the
44, the ram-pressure small-winged paraglider 44 has a wing body 47 which is formed by connecting a bag body 46 in the lateral direction with an opening 45 formed in the front part, and has a closed front part on both sides of the wing body 47. An example of a left-right movable small wing in which a wing tip material 49 formed by vertically connecting the bag bodies 48, and an opening 50 formed in the front part at the rear of the wing tip material 49, rotates in the left-right direction. It is constructed by attaching a ladder 51.

By operating the control cable 52 connected to the rear of the rudder 51, the rudder 51 can be moved left and right as shown by the two-dot chain line in FIG. 4, and can serve as a rudder.

In addition, the above-mentioned ram pressure type paragliders with small wings - 20 and 44
