Do cannon shells bounce in real life?

[maturin 12]

Whenever you fire the gun on the nose of the AH-1z or Hind, you get an awful lot of ricochets. Shouldn't a HE cannon shell detonate before it can bounce anywhere?

I have also seen entire salvos of tracers from the A-10 bounce off the ground when fired from a low angle, but I assume the tracers are not explosive.

The tracer rounds on the A-10 are HEI-T rounds (High Explosive Incendiary - Tracer) while the rest are armour piercing (at least IRL. Not working like that in game due to engine limitations).

But yes, HE shells should detonate without ricochets unless fired at a very low angle, in which case they could bounce off without the fuze actually hitting anything.

Not sure if the Hind actually use any HE ammo in the Yak-B gatling gun though, or if it's all standard ball or armour piercing ammunition. My guess would armour piercing to carry through a good effect on soft targets at decent distance.

Read the part of the article concerning the m61 vulcan.

Moreover, I was reading ground attack techniques a while ago and I saw a diagram that insisted that the climbing egress from a strafing attack should be steep so the attacking aircraft can avoid being hit by its own cannon shells.

I am not sure what the m61 is usually loaded with, however.

Yes, they do.

Another question about the AH-1z cannon. It makes a very dull nonthreatening noise (almost like banging two blocks of wood together) when it fires and you have vopsound installed. It sounds nothing like the other cannons in the game.

Does anyone with vopsound know how accurate this is/why it is so quiet?

The sound of the cannon in real life is very loud. Much louder than the helicopter itself- and I've never had an ah1 fly over my head but the uh1 is quite loud.

The sound itself (at least in SOWmod) resembles the sound of the cannon in the cockpit well enough (albeit, even in that mod, the weapons are loud enough).

Since posting, I have noticed that cannon shell ricochets cause explosions at both impact points, which seems slightly impossible. So chalk one up for the bug reports.

Its even possible with artillery , IRL we often have to fire higher charge (unfortunately raise the flight time) to impact at la higher angle so that it doesn't rebound.Prox and time fuzed rounds as well as mortars don't have this problem tho

Is it just me or is that a very weird looking cobra? I thought the canope was more rounded, without a crossbar in the middle. This looks very angled.

The W and Z are rounded, not the older models.

That is the very first Cobra model...they look way different, even have 2 rotors and not 4

[jasonnoguchi 11]

Yes, I have seen cannon shells ricochet in RL. In fact, I have even seen 76mm cannons with SABOT shells ricochet!

No, not at all. This is actually like the fifth ah-1 model.

The rounded glass canopy was present on the first ah-1 models.

AH-1G - initial Vietnam war variant.

AH-1Q - AH-1 G with the TOW subsystem.

AH-1S - AH-1 Q with an uprated power plant.

Then the more modern ones had flat plate canopies:

AH-1P - Ah-1S with composite rotors, improved cockpit, and flat plate cockpit.

AH-1E - AH-1P with Enhanced Cobra Armament System (20mm cannon), and Rocket Management System.

AH-1F - Ah-1E with laser range finder, a data sybsystem, infrared suppressor and infrared jammer.

Additionally, all twin engined marine variants (J, T, W, and Z) have rounded glass canopies.

Since this export one has a 20mm cannon it must be either an AH-1E or F.

Edit: Max got it. He knows more than I do.

The one in the video belongs (I think) to the Japanese (G-something) Self Defense Force.

yea its from the JSDF.

the helicopter's canons sounds in arma are very quit compared to RL i've seen apaches , cobras tanks firing and for the helis i could hear the canon about 2km away (since they are high and nothing to stop the sound wave)

Wouldn't a higher charge number be a lower elevation? Did you mean to say a lower charge number and a higher elevation?

[max power 21]

He didn't say charge number, he said charge.

That I agree but on the other hand, tank blast are deafening if you are within like 50m but you can't produce that loud a sound on a game right? hehehee... gonna blow up our sound systems. :) Even M16s are really loud when fired just beside you... much louder than can be reproduced by the game. For a really loud and solid GAU cannon sound for A10, check out HiFi A-10 sound mod. :)

That still doesn't make sense... :p

Bigger charge as in different caliber guns?
