WebThe pilot can adjust between 2,100 or 4,200rpm, so total firing time is between 38 and 19 seconds. However, most firings are in 1–3 second bursts which means most of the time the A-10 can engage with the gun somewhere between 6 and 14 times. Add to that the 11 pylons and the bird can potentially engage 17…. Web22 dec. 2024 · You are correct, the bullet would not hit the earth at the same speed that it left the gun barrel, it would return at “Terminal Velocity”, the fastest an object can fall in the air. US Army General Julian Hatcher did a detailed study of this in a publication called “Hatcher’s Notebook”, published 1966, which is available on the Web for free.

WebFirearms are designed around a Maximum Average Pressure (MAP), which is the peak tensile strength of the gun's action and barrel reduced by some safety margin. Typical MAP in rifles is around 60kPSI. This is essential to answering your question, because it means that the peak force acting on the bullet is limited. WebHow many times does a bullet spin in the barrel? Thus, at 3000 FPS, a bullet will be spinning at 3000 x 60, or 180,000 RPM, when it leaves the barrel. Although it’s rare that a bullet would spin more than 3000 times before it hits the target. Most would spin maybe 1000 revolution. phim autopsy of jane doe

That’s equivalent to over 1,800 miles per hour. To put that in perspective, it’s amazing to realize that bullets travel over twice the speed of sound! WebThe faster the spin, the less likely a bullet will "yaw" or turn sideways and tumble in its flight path through the air. Thus, increasing the twist of the rifling from 1 in 7 will impart greater spin than the typical 1 in 12 spiral … phim avatar 2 trailer
