SHREK ROCKETS GOING THRU ET AND NOT EXPLODING?!

[jw1984]

Shrek rocket going thru the enemy tank and causing no damage.  I have seen this happen from close range and further off just as in this video.

If the angle is too much they don't fuse.

I can not really see of the rockets hits the target. I see explosions besides the Sherman each time you fire.

You need to get up much closer to really show the issue. This can very well be that you don't hit the target.

Close enough?

How is this for an angle? Directly behind the tank...

1. Watching the first shot at 1/4 speed with frame stops, the sight point is rising as you fire, and also moving to the right. Not your intent, but there it is. And, the sight is set for 100 meters, right? But I think you're closer than that. So, the rocket will fly higher than the aim point on the way to the sight set distance. It may have gone over the turret.

2. The second shot may have been high as well, but more importantly was aimed at the rounded left side of the rear turret aspect. If it hit exactly at the aim point, it may have not fuzed due to angle. And, if it hit somewhat higher than the aim point because of range, the angle would be worse.

3. It looks to me like the third shot went over the front of the tank. The aim point was right at the top edge of the front deck, and you got closer so the aim rise would be greater than for shots 1 and 2.

4. The fourth shot definitely went over the front of the tank. The aim point at the moment of firing was above the front deck.

5. Crazy impossible reload speed with two men, as historical...for sure impossible with one, not that he could carry four rockets. Not the point of this thread, and not your problem, but it'd be nice if CRS could get it closer to realistic.

no this is a thing.....He isn't missing the target, hes right on aim..... trust me I know.... happens to me alot as well...... just straight up miss fires that don't explode or do any damage.  I first thought it had something to do with moving well loading but that isn't the case.  Not sure what is causing it, but this same exact thing happens to me I would say 1 out of 20 times I fire a round

gj on getting that 2nd video up..... thats a clear capture of the issue for 2 shot in a row

Can't share full logs but this snipet hopefully tells the story [Thu Apr 04 15:24:27.622 2019] WEAP rpzb4322heat(1) richocheting off d_topbak(0)      Sherman tanks have a sloped back deck.  Watch the vid in 1080 res or higher to see the ricochet sparks effect.

Good stuff Zeke

[kgarner]

so you're saying the round bounced off?

[kgarner]

I have hit sherms in the flame spot with no angle at all and had the same thing happen..... no damage.  Then the very next round in the same spot causing the flame the first should have...... this is point blank in the veh spawn so there is no user error happening...... Ill get some video, i guess

Another unrelated question, but the relevant people probably see this thread: what is the supposed physical basis for the panzerschreck tube "recoil effect", i.e. the muzzle climbs as displayed by sight picture upward movement?

The rocket exhaust has some drag on the inner surface of the tube, thereby creating a rearward force. The exhaust is a gas, therefore the coefficient of friction against the tube inner surface is very small. The exiting rocket has some drag on the inner surface of the tube as it departs, thereby creating a forward force. The rocket is metal, the tube is metal, so the coefficient of friction in that direction is much larger than for the exhaust gas process.

As an engineering approximation, the two forces are nearly equal, so the tube would remain unperturbed.

If the analysis is intended to be detailed enough to evaluate a small force imbalance, I think it'd be in the opposite direction...a net force forward, which might push the muzzle slightly downward.

The same physics would apply to the bazooka. Not the PIAT, though...it has lots of unbalanced force actions during its firing cycle.

you hit spots on the armor that have a "bad" angle ... the round bounces off ... which is fine imo and kinda "realistic"

always aim for "flat" plates ... that face you in a perfect angle if possible. in that 2nd video you should have aimed for the back of the engine ... but which in the end would only blow the engine (or sometimes just smoke it) and not kill the crew or flame it

 

i guess what he means is that you shoot a tank and the round just goes through the tank and explodes on ground ... same happened to me many times with PaK and Tiger shooting ETs. as if the enemy tank model is not there at all or the system doesnt recognize it correctly. reminds me of the incident i had many maps ago near Boulogne when me and Saffroli were both engaging an M10 at 1000m range. we both fired like 15-20 AP rounds each ... and most of our rounds just didnt show any impact animation at the front hull of the M10. M10 just kept shooting ... no smoke ... no fire. firefight was like 1 min. for both of us one of the biggest WTF moments in this game we had

 

i have also noticed that Panhard / Vickers / Daimler are very resistant vs. Panzerschreck rounds. you can be right next to them and shoot a perfect angled round into their side ... doing nothing. all crew fine although the driver or gunner should be dead for sure. even rounds into turret from side mostly do nothing.

Unfortunately those who originally made it and could maybe answer though wont see it.

Personally, i could not tell you, the shreck and zooka are recoilless anti tank rockets
and since both load at the rear, i doubt it is from the sudden loss of weight.

I doubt there is much tube friction either, cause if you load either of the two and decide to go wandering off on a hike
you are liable to drop the rocket out on the ground and have a very bad day, and if there was, as you say, down is the direction you would go.
