Where Can I Find Angular Velocity Data for Different Types of Bullets and Guns?

In summary, the angular velocity of bullets is the rate of change of the angle at which a bullet rotates around its central axis. It is calculated by dividing the bullet's linear velocity by its distance from the axis of rotation or by multiplying its angular acceleration by its time of rotation. This measurement is important in ballistics as it affects the bullet's stability, spin, and trajectory. The angular velocity of bullets typically decreases during flight due to external factors such as air resistance. It can be altered by adjusting the bullet's mass, shape, or velocity, but it will also naturally change as the bullet travels and rotates.

Does anyone know where I can find a list of angular velocities of different kinds of bullets fired from different kinds of guns?

I don't know about a list, but if you google "bullet rifling rotation rate" you'll get a lot of relevant hits.

There are several resources available online that provide information on the angular velocities of different types of bullets fired from various firearms. One such resource is the website of the National Institute of Standards and Technology (NIST), which has a database of ballistic measurements for different types of ammunition. Another resource is the website of the International Ammunition Association, which also has a database of ballistic measurements for various types of ammunition. Additionally, many manufacturers of firearms and ammunition also provide information on the angular velocities of their products. It is important to note that the angular velocity of a bullet can vary depending on several factors such as the type of gun, the barrel length, and the grain weight of the bullet. Therefore, it is important to consult multiple sources to obtain accurate and comprehensive data on the angular velocities of bullets.
 

1. What is angular velocity of bullets?

The angular velocity of bullets is the rate of change of the angle at which a bullet rotates around its central axis. It is measured in radians per second and is affected by factors such as the bullet's mass, shape, and velocity.

2. How is angular velocity of bullets calculated?

The angular velocity of bullets can be calculated by dividing the bullet's linear velocity by its distance from the axis of rotation. It can also be calculated by multiplying the bullet's angular acceleration by its time of rotation.

3. What is the importance of angular velocity of bullets in ballistics?

The angular velocity of bullets plays a crucial role in determining the accuracy and trajectory of a bullet. It affects the bullet's stability, spin, and ultimately its impact on the target.

4. How does the angular velocity of bullets change during flight?

The angular velocity of bullets typically decreases as the bullet travels further from the muzzle of the gun. This is due to air resistance and other external factors that slow down the bullet's rotation.

5. Can the angular velocity of bullets be altered?

Yes, the angular velocity of bullets can be altered by adjusting the bullet's mass, shape, or velocity. It can also be affected by external forces such as wind or gravity. However, the bullet's angular velocity will also change naturally as it travels through the air and rotates around its central axis.
