Bomb Doors
« on: July 13, 2011, 11:21:30 PM »
Why is there an indent in the end of the bomb doors?  Is it to clear something in the bomb bay or what?
Image of what I am asking about is below (taken of the bomb doors on XJ824)

It is only on the front end and not the rear end.

They are access doors which allow access to the bomb bay when the doors are closed. :)

Has anyone got a photograph of these little doors open whilst the big doors are shut?  Just so that I know what they look like.
Thank you in advance.

No they are the special doors for loading extra Jaffa Cakes.

You can see them (closed) at 30secs in

Doors can be seen open by step ladder. Second photo is taken from the top of those steps.

I don\'t want a second childhood. I\'m still enjoying the first one.





I\'m retired.
I was tired yesterday, and I\'m tired again today.

There is also a picture taken by Mackrick on 28th January 2010 which shows them closer up (as seen on his webpage).

Getting to the bomb bay when the front "A" fuel tank was fitted (see your original photo Minty) was easy because of the concave profile at the bottom of the tank.  This was designed so the tank would fit over the profile of a blue steel missile if the ac was in that role.  "The Blue Steel Role" bomb day doors were completely different to the ones fitted to XH558.  I never worked on a Blue Steel ac so perhap some body might tell us if they had opening doors at all or was it a fixed rigid structure  :?:

If a front drum tank was fitted. getting in through the access doors was very tight indeed.  People of "larger proportions" would simply not get in.  :oops:

As I remember,they had access doors and a "fin gap" door which allowed the upper fin of the Blue Steel missile to pass up into the bomb bay,my memory is a bit hazy but that is what I recall.

Yes there were 6 access doors in a Blue Steel Vulcan to the bomb bay except they were positioned about 4' aft of the forward end of the bomb bay doors. There were also two further access doors about half way down the bomb bay and at the rear of the bomb bay.  If you own a 1/72 scale Airfix model of the B2 bomber and look at the Blue Steel version bomb bay doors you can clearly see where they were.  

The doors were of the hatch type, similar to Panel 10 and the 4' space between the hatch and the forward end of the bomb bay was to accommodate two inwards facing jump seats inside the bomb bay one either side of the aircraft.  These were used by men in grey flight suits, (boffins and techies), for testing purposes during the initial set-up and testing phase when Blue Steel was first deployed to the Squadron.  The seats had their own comms, oxygen and suit heating controls etc, similar to the cockpit jump seats and yes they did fly sat in the bomb bay with their test rigs plugged into where-ever.  :)

Amazing to think tat they flew sat in the bomb bay.  Was it pressurised?  I know there was was bomb bay heating on the conventional role ac.

If it was a James Bond Thunderball moded ac, they could have accessed the cabin in flight through the access door via the No 1&2 fuel tanks  :)

I'm pretty sure the bomb bay wasn't pressurised as far as I remember the jump seat console held the same instrumentation and controls as the ones in the cockpit.  The crew did wear some type of air conditioned under garment that would have plugged into the aircrafts air conditioning system.  

One of the tests I was involved in was when the missile ground simulator was all plugged in.  I was told to enter the bomb bay and sit on a jump seat.  At some point during the test I had to move aft to the missile release mechanism and on instruction manually activate a micro s/w to simulate a 'missile gone' condition and hold it down until I was told to release it.  I can clearly remember seeing the test rig through the missile release mechanism so I'm pretty certain no pressurisation.

We had an in-flight spurious cockpit light coming on that we couldn't simulate on the ground.  It was eventually tracked down to a condensation ice bridge across electrical contacts in the starboard electrical panel in the forward bomb bay bulkhead.  After a corporal rigger hero went up in the bomb bay jump seat to visually confirm the fault they changed the panel cover seals and the fault disappeared, so definitely no bomb bay heating. :D
