Principle of darts

Q: why do darts need a tail

Answer: darts without tail will swing left and right in the air, and there is no accurate head.

Q: please analyze the force on it during flight

Answer: the dart will cause air diversion in the process of flying. Due to the uneven material and air convection, the resulting pressure is not equal everywhere, which will make the dart shake. The tail wing can make the dart tail ensure equal air diversion, so that the tail can fly along the correct parabola, so as to keep the dart balanced. darts accessories

Q: what is the difference between the tail of an aircraft and the tail of a dart

Answer: the thickness of the tail wing of the aircraft is inclined. When flying at high speed, the air flow through the tail wing has unequal pressure up and down. The pressure below is large, which will press the tail wing up, so that the aircraft can fly in parallel in the air and will not be a downward parabola like a dart.

Q: how does the tail ensure equal air diversion at the tail of the dart

Answer: soft tip darts the tail wings are all around the tail. In the process of flying, the air will form an outer conical flow. If there is no tail wing and there is no air flow in the tail of the dart, the pressure will be formed. The tail wing is to make the air pass over the tail wing to ensure that the tail wing does not swing left and right under the action of pressure.
