Is Arma 3 authentic?

[Liquidpinky]

I understand how rail guns work, thank you. In the first place, heating the round is not really a concern, as the round will be heated by air friction as well, and do not forget rounds in conventional chemical weapons are also very hot. Where wear is a concern is the barrel. Wear in a coil gun would be very similar to a rail gun. In both you would have very high friction on the inner surface of the barrel, and you have massive heating due to the resistance associated with either the rails or the coils.

Would actually be the current causing the heat as the coil resistance would be quite low.

@ Iratus, a wind turbine couldn't power a mouse fart BTW, they are the white elephant of todays technology.

Concerning the MI48 Kajman, it's remain a fictive helicopter because it's an hybridization attempt of MI28 and KA50.

-coaxial rotor,
-triple barreled turret cannon (pure invention of BI that doesn't exist either on KA50/52 or MI28)


why BI doesn't simply implement the real MI28 instead ? it's better to play a military simulation with realistic equipements that have verifiable and observable characteristics IRL.

if the developers start to take the liberty of implementing fictive stuffs (not even prototypes) it can tend to open the pandora's box for the rest.

Yay, this again...

Does the cannon (looks like a GAU-19 or M197 to me) have verifiable specs? Yes
Do the missiles have verifiable specs? Yes
Do the rockets have verifiable specs? Yes
Will it have a specified fuel capacity? Yes (engine specs and rotor configuration dont matter in the ArmA series)
Will it have a specified top speed? Yes

I really dont get how its so different from anything else. Afterall, the visual model makes jack shit of difference when it comes to the actual performance ingame.

People need to chill the fuck out and stop making such straw-man arguments for why the Mi48 is "the end of all things!!1!!11!!1!!"

It's a slippery slope and we're taking everyone for the ride!

But... but... aehm...
Oh well, you're right about this. They just came into my mind because I was thinking about energy sources on the island. At least the Iranis can use those wind turbines to charge their iPads while firing the railcannon

Errr, it is resistance that would cause energy loss in the form of heat. And, technically, since the coils are wrapping around the barrel, resistance would be higher in a coil gun than in a rail gun, as resistance increases with the length of the conductor. Of course, since the coils are essentially segments, each individual coil might not be more resistant than a rail gun, but there is no reason to suspect that a coil gun would have inherently less resistance than a rail gun. I would think at least around the same resistance.

I hope they expand the realistic Flight model from ToH on Helicopters with coaxial rotors. They have totally different fligt dynamics.

The arguments about the Merkava tank are dumb. Why argue about something projected 20 years in the future? The very symbol of Soviet Communism, the AK-47



is almost a copy of the German StG 44



So Communists were very content to perfect a weapon designed by Nazis. Thousands of German scientists worked for the armaments industries of the West and East following the end of WWII.

http://www.projectrho.com/rocket/spa...pons--Railguns Projectrho on railguns. Also has a power calculation for the shell, to give you an Idea of range and damage, as well as power consumption.

The rails suffer from massive abrasion due to the shell´s sabot being in contact with them. The energy flows trough the sabot and pushes it forward trough lorentz force. So the rails get rubbed down with each shot, and they get -very hot- due to inefficiency issues and friction. (I would imagine if the efficiency limit for a perfect railgun is similar to that of a perfect laser, total efficiency would be around 50% or something. That means half of the energy fed into the weapons system would be turned into waste heat.)

Problem is energy, obviously. The Navy´s proposed weapon has an energy on target of 32MJ (Being fed by 64MJ of energy), with a range of 200+ nautical miles. Such ranges aren´t needed for a tank projectile, 5 ish kilometers would suffice.

The Ak-47 is nowhere near a copy of the MP-44. The only real similarities are they're guns, have detachable box magazines, and are assault rifles with a gas piston. The AK was INSPIRED by the MP-44, but that's like saying the M-16 is a copy of the AK because the AK came first and they use the same idea or that the K-98 is a copy of the Mosin Nagant.

They're about as similar as the K98 and the Mosin are.
