The Navy’s Rail Gun technology hides a secret, that the Navy’s projectile accuracy has been substantially increased by about 45x.
But first some history.

The US government brought Prof Eric Laithwaite to help them build a rocket launcher based on linear motor principles. Today we call this the Rail Gun. In terms of its original objectives it was not a success, because astronauts could not survive the accelerations required to launch from a rail gun and cargo required a much longer rail gun than feasible with the then technologies.

The Navy succeeded with ship based rail guns as a means to shoot projectiles. Bloomberg TV has a good video on the Navy’s Rail Gun. http://www.bloomberg.com/video/watch-navy-s-new-supergun-launch-shells-at-5600-mph-bfCXOGXZQziZgHnsbq9VzQ.html

Watching this video I realized that the secret to the Navy’s Rail Gun project was not the rail gun itself, but the substantially increased accuracy attained by the much higher muzzle velocity.

I present two important point. Using quick & dirty theoretical reasoning and real examples showing that the rail gun projectile has an increased accuracy of between 28x to 45x over conventional ship-based guns.

And the real possibility that the rail gun projectile traveling at Mach 7.4 has the ability to shoot down the X-51 traveling at Mach 5 at an altitude of 70,000ft.

Recently I had an interesting discussion about Laithwaite’s Big Wheel demonstration.

Note that the late Professor Eric Laithwaite was Professor of Heavy Electrical Engineering at Imperial College, and inventor of the linear motor, and the maglev train technology which Germany and China have taken the lead. The poor Brits they missed out on their own invention.

The Big Wheel experiment is basically this. Attach a wheel to the end of a 3-ft (1 m) rod. Spin this wheel to 3,000 rpm or more. Then rotate this rod with the spinning wheel at the other end. The technical description is, rotate the spin vector.

The Ni fields solves the Big Wheel experiment to give acceleration a=ωrωs√h is governed by the rotation ωr, spin ωs, and the physical structure √h, and shows that both weight loss and gain are observable. If the spin and rotation are of like sense to the observer, the force is toward the observer. If unlike then the force is away from the observer.

Then somebody pointed me to link at Imperial College that said that the late Prof Laithwaite had “coming to a series of false conclusions”. I was very surprised, especially since I did both my undergraduate and post graduate at UK Universities.

All this ‘exotic’ mathematics to prove Laithwaite was ‘wrong’. What arrogance. If Imperial College had asked very simple and obvious question they would not have posted such nonsense. How can the human wrist carry a 50lb (approximately 23 kg) weight at the end of a 3 ft ( 1 m) rod? Obviously this Imperial College ‘research’ was conducted by someone who had no idea how to do emperical validation.

This raises the question, are British Universities into closing off the minds of future generations or are they about empowering their future industry leaders to find the … truth?
