Title: bombs
Post by: chrish483 on November 14, 2009, 04:08:53 PM
watching the movie pearl harber  (remake) i noticed the scene where a jap bomb droped to low landed in a flak bunker, the arming impeller was still spinning then stopped and then exploded.   was that left out of the code for the ones we use?

Just to let you know, that movie is infamous for it's total lack of historical accuracy.

Pearl Harbor is to historical accuracy as Nazi Germany was to tolerance.

Could have had a delay setting.

Our impeller only turns for 1000 feet of travel.  If the bomb stops, so does it.

The bombs in B-17s and B-24s have pins inserted in the impellers that are pulled before the aircraft reach the IP. The impellers should not begin spinning until the bomb drops but sometimes they did. After so many rotations the bomb is armed and any jolt will set it off unless it is a delayed fuse (some bombs were fused to explode as much as 24 hours later). If the target could not be located and the bombs could not be dropped on a visible target they might try to bomb by radar or they would reinsert the pins (if they still had them) and drop the bombs into the mountains or lakes or whatever. Bombardiers had enough on their conscious as it was and didnt just drop the bombs on anything (according to the books they wrote anyway). Sometimes a bomb would hang in the rack with the impeller spinning in which case they would pry the bomb loose and let it drop. You never want to land with a bomb slung in the rack.

One story I read indicated the bombardier had dropped the pins in the bomb bay and the navigator had taken a leak in the bomb bay after the relief tube had frozen over. The pins were frozen to the doors and the doors frozen together so they could not bomb and they could not dump ord either. They dropped to low level until the puddle thawed and the bombardier made the navigator reinsert the pins before they dumped ord in the Adriatic.

AFAIK the bigger AP bombs the Japs used at Pearl were modded naval arty shells.
And the way of torpedoes travwelling in that shallow water was actually adapted from the British which made an excellent torpedo attack at Taranto, at NIGHT some while before Pearl.
There is a good part in the movie though. Kate Beckinsale  :devil

Yes, Brother Bluto. ;)

Hoho, it's not just bad movies that eschew historical accuracy. Yesterday, I was watching a History Channel bit of stuff-'n'-nonsense about the Pearl attack, in which the inane commentary stated that the battleships sunk at Pearl were the first. Obviously the so-called writer had never heard about Taranto.

And the 'Great Planes' series on Discovery. What a crock. Any old aircraft newsreel film they like stuffed into the intervals between the talking. If I see that Lysander going into the sea one more time . . .

 :huh

What's the point?
No one is ever going to see the impeller let alone whether it stops or doesn't.

He wasn't asking about visuals. He was wondering if we could set the delay on our bombs to go off after a certain time instead of on impact. That would allow skip bombing like in Il-2.

wouldn't it be a blast(pun intended) to have a panzer killed as he drives over a delayed fuse bomb?

could you imagine the whines?

 I reread his post again to be sure and it certainly sounded like he was looking for visuals.
 No where did I see him allude to or ask for setting a delay let alone skip bombing but
kudos for being able to translate what he did write into that!

I gathered it from that being the purpose of the impeller...I dunno, I'm hopeful he was asking for something useful.
Title: Re: bombs
Post by: Chalenge on November 18, 2009, 10:57:55 AM
Skip bombing (possible with delayed fusing) would bring out a potential in the P-51D that has not been realized in the game so far.

I presume someone has already asked for delayed-action bomb fuses and/or parachute-retarded 'parafrag' bombs in 'Wish List'? If not, I might open a new thread there.

Actually, it was even brought up at the 2003 convention. The reply was along the lines of not being worth the effort.

Anyone know how the delay washer works?  Looks like it would just stop the arming plunger from moving down at all.  What breaks the delay washer after a given amount of time?
Title: Re: bombs
Post by: Baumer on November 20, 2009, 05:18:59 PM
It gets pierced on impact, look towards the end of the operation paragraph.

Post by: Brooke on November 20, 2009, 08:44:39 PM
I could be wrong, but my understanding is that it's not impact that pierces the delay washer.  The inertia ring is slammed forward by impact (opposite direction of movement of the arming plunger), and then the delay washer holds back the arming plunger for the delay period after impact before letting the arming plunger release, it seems.

Or better yet, set it to explode right above the tank.

Your right Brooke the inertia ring moves forward (towards the top of the nose) on impact, that allows the ball to fall out of place. Then the spring releases and after approximately 20 seconds (i imagine) the delay washer breaks under the spring tension and then the plunger strikes the cap.

hmm... delayed fuse bombs, that would be the PERFECT strategy to bomb a field and get tons of perkies. carpet the field with eggs,everyone starts thinkin "lol it was just a noob lets all go pwn him in 262s" and ups,THEN they go off and you land your 8 kills  :D

Would be less effective; more armor on top than bottom, more air to travel through before the force reaches the tank. Although, bombs ricochet off tanks in this game, so... :D

"hmm... delayed fuse bombs, that would be the PERFECT strategy to bomb a field and get tons of perkies"

The USAAF light bomber crews that attacked Japanese airfields in the Philippines and New Guinea from tree-top level thought so - the parafrags blew the wings off parked aircraft a treat. And delay-fused bombs would restore some of the surprise element that's rather gone out of airfield attacks lately.

How long are you willing to wait in the tower for your bombs to go off.
