I'm looking for a compromise that can be quickly put in place, Westy. I think one reason the sewercide heavy bombers are so prevalent is that they have 3X defensive firepower over a single tactical bomber, and 2 spare "lives" they can lose during their knuckle-dragging attack.
So if you restrict heavy's to only bomb from the bombardier position when in formation mode, then if people really want to Jabo a B17, they only have one plane to do it in - like any other Jabo. This won't completely stop the behavior, though - as I pointed out before you can get pretty good at guessing as long as you're willing to fly straight. But it really cuts the accuracy and easiness down to where you're better off with an A20.
As for the rack systems themselves, I don't have enough data to say what is accurate. But looking at them and remembering a little about fizzicks, we can maybe make some assumptions. One is that the racks are meant to hold the bombs ready to release downward and most likely not meant to sustain heavy G loads because of the concentration of mass (3 to 7 tons of HE in a small area). So it makes me wonder about ...
- if you push -G's, are the racks set up to prevent bombs from flying up through the roof of the plane? We know that if they're released in level flight they'll rip the bay doors off if they're closed, so I'd expect similar damage in the other direction.
- If there are safeguards for -G's, what will this do to the release mechanism (which is meant to regulate downward travel)? Do the release catches get bent by bearing loads in the "wrong" direction?
- If heavy +G's are applied, how much force can the racks sustain before the bombs break free by shear weight of F=MA? A 3G pull-out for a low-level dive bombing attack from a Lanc could put as much as 21 tons of force on the center of the plane, let alone the racks themselves - that can't be good for structural integrity. If the stress can be taken, will the racks still function? Will they get bent?
Some of these same questions apply to the bomb shackles on Jabo fighters.
