Hop Up Cushion for AEG Airsoft Gearbox All Marui Version Hunting White Black | Спорт и развлечения

Hop up In Airsoft, the BB can be fired with an upward rotation. The principle is that when the BB is flying forward and the air is rubbed, the air will slide around the BB. If the BB is rotating upwards, the air will pass through the lower part of the BB and will have a smaller flow rate due to its rotation direction. On the contrary, the air passing through the top of the BB bomb is opposite to the direction of its rotation and thus the flow rate is large. According to Bernoulli's theorem, a slight lift occurs when the flow velocity below the object is less than above, which can greatly slow down the speed of the BB bomb and increase the range. The faster the rotation speed, the greater the difference between the upper and lower airflow rates, and the greater the lift, but the excessive buoyancy will cause the BB to "float" upwards. If this Airsoft's Hop-Up is adjustable, it should be adjusted to a ballistic about a straight line.
