Why can you control the direction though?
When people parachuted from a height of several thousand meters down, there was no fixed down trajectory, but the athletes and the soldiers' soldiers could still control though, preparing to descend to the intended position, they How to control the landing direction?
When humans created it, they calculated this problem. We all know that, when the fabric is turned on, the air density inside will be greater than the density of the outside air. The designers began to think from this point, they coded up on every parachute second, then tied up a short piece of rope at the end of the first parachute and the final parachute; on the short piece of rope, tie a joystick to the parachute strings.

When the parachute wants to turn left, just drag the left handle down to pull the rope even though it is moving downwards, making the parachute of the left side of the air outlet recessed into the interior, and the cloth on the side Right of the air outlet is protruding, the air inside the parachute will escape from the two right sides of the air outlet. At the same time, generates a contrasting force that causes the parachute cloth to push to the right, so though it will move to the left. Likewise, when pulling the right controller down, though, it will switch to the right.
