In this video I'll show how you can measure the speed and energy of a bullet fired from a coil-gun.
I compiled the coilgun model according to the attached circuit.
The main parts of an electromagnetic gun are a storage capacitor, a coil and a projectile.
When the capacitor is discharged to the coil, a magnetic field arises that accelerates the projectile.
To measure the speed and energy of the bullet, I made several measurements that I entered into the calculator.
That's how I measured the distance from the coil to the target.
The core of the bullet I made of mild steel and attached to it the tip and stabilizer.
I weighed the bullet on the scale.
To measure the flight time of the bullet, I connected two sensors to the Audacity free program.
I put the inductive sensor near to the Gauss Gan coil, and the piezoelectric sensor attached to the target.
As a result, I got the value of the speed and energy of the bullet, as well as the efficiency of the gun.
