What's the difference between archery bow, compound bow and recurve bow?

The difference between the two is that the competitive aiming bow used in the competition is less powerful and requires higher accuracy and stability.

Compound bow: Bow and arrow are compound long-range weapons. It consists of two independent parts, bow and arrow, and arrow is also called vector or chain. "Archers shoot arrows with bowstring". Bows and arrows use the principle of elastic potential energy of materials to combine human strength with the elasticity of objects, so that arrows can shoot into the distance and reach the goal.

The invention of bow and arrow is a great progress in human technology, which shows that people have understood the truth of mechanical energy storage: when people pull the string hard to force the bow to deform, they store their own energy; Release your hand and the bow will soon return to its original state; At the same time, the stored energy is violently released, and the arrow on the string is forcibly shot.

Recurve bow: Also known as naked bow, it is a kind of bow whose side looks different from ordinary long bow: the end of one bow arm of recurve bow without bowstring bends outward. One of the special definitions points out that the difference between recurve bow and other bows is that recurve bow's bowstring, that is, the winding person, is in contact with its bow arm.

Compared with the straight-arm bow, recurve bow can store more energy, which makes the shot arrow have higher kinetic energy. So recurve bow can make it shorter than the ordinary bow, but it can keep its power. This advantage makes recurve bow suitable for places where long weapons can cause inconvenience, such as jungles, forests or horseback riding. Relatively speaking, the traditional straight long bow will have a "cascading" effect-that is, the more the bow is pulled open, the greater the force required to pull the bow.

Extended data

It is mentioned here that the long stick on the bow used by many players is called the balance bar. The main function is to make the extension line of the whole bow perpendicular to the ground, balance the front and rear strength of the bow and reduce the vibration of the bow. Simply put, it is to let the shooter play his level more stably.

The balance bar pulls the center of gravity of the bow forward, and after the balance of the front and rear hands disappears at the moment of shooting, the counterweight is added to balance the lifting action of the front hand, thus reducing the disturbance to the arrow tail. Through the side balance bar, the center of gravity caused by installing the sight is balanced to the right, so that the bow body is naturally vertical to the ground when lifting the bow. For the middle launch bow, it is best to install two side balance bars to lower the center of gravity of the bow and achieve overall balance.

The balance bar can absorb vibration and play the same role as the shock absorber. It can also make the bow have melee function and become an effective melee weapon in the case of conflict.
