・最初は楽しそうでした
・あれってパラシュートだよね？
一体彼らは何をしようとしていたんだ？
ゆっくり空から落下するように作られたものでしょ
凧じゃないんだけど（笑）
・凧としての使い方もあります
彼らが実践してますね
パラシュートで引きずられる人
・引きずられてズボンについた草のシミを落とすのは大変でしょう
・逆再生ではないでしょうか？
彼女は文字通りパラシュートを使って空から落ちてきた
減速して着地してるように見えます
・白いズボンは捨てることになりそうです
土汚れって本当に落ちないんだよね
・これは笑い事ではありません
・でも僕は笑ってる
・周りが助けようとしていない
・なぜ誰も助けに走って行かないのですか?
・みんな動画を撮影しようとスマホいじってるのだろう
・笑ってしまい申し訳ないです
漫画みたいな光景だな
Turn
Example)Right turn
Pull the right toggle of the advancing parachute, bend the trailing edge, and apply the brake.The left side of the parachute tries to move forward, but the right side also has a smaller projection area, and the right side goes down and turns to the right.
The turn occurs due to the difference between the right and left toggle, and if you pull the right toggle, you turn right.
The amount of the toggle determines the size of the arc drawn, and the altitude is lost in proportion to the amount of the toggle drawn.
Flared Landing
Square parachutes are designed as tools to advance and land on the desired ground, usually with an attack angle of about 15° from the front to the back.It does not have a lift angle like a hang glider.
Therefore, it is thought that braking on the parachute that is already moving forward moves the weight of the person forward, changes the angle of attack made on the ABCD line, and creates a pick-up angle, so that the parachute can easily land by gaining lift.
After seeing the point where your feet are installed on the ground, lower both the toggle so that you put both hands on the lumbar bone of your body just before the collision.When you land, you have to measure the time between the movements so that the speed will disappear.
When the flare starts too early (too high)
Stop the toggle halfway. (If you think it’s too early, don’t pull the toggle to your waist.) If you pull it to your waist, don’t put the toggle back and prepare for P.L.F.
As a characteristic of a square parachute, if you pull the toggle up, the parachute crashes into the ground trying to change to an attack angle that dives.It is necessary to recognize that it is very dangerous before landing because the body moves back and forth and the opposite result of the flare occurs.
