H2S Rebecca AGLT G_H panel Halifax, Stirling?

Was AGLT ever fitted to anything other than Halifax, Lancaster and Lincoln?
I agree that Lincoln is looking to be favourite for this panel.
Andy

Yes, I agree. The only meaningful way to do trials with several different radars is on the whole aircraft in flight and after that each system could be tested on its own.

I am drifting back to the Lincoln theory …

From the Pilots Notes “An alternator may be fitted to each outboard engine to supply special radar equipment, but when Mod. 1430 is introduced these two alternators are replaced by two 6,000-watt (sic) generators which feed into the aircraft batteries in the same way as do the generators on the inboard engines. The special radar equipment then gets its supply from two Type IV motor generators installed in the aircraft and driven from the main aircraft batteries.”

Was it practice back then to have a comprehensive ground test rig fitted with all the aircraft electrical/avionic systems? I’m thinking (but I’ve no evidence) that this is a later concept, developed as systems complexity grew as did interconnection between systems.

It’s a fascinating item!

Andy

… or ground test rig either for that matter!

I am losing hope that it was aircraft fit. The part numbers look plausible for Armstrong Whitworth. I had a fairly short list and Lincoln was on it.

If it’s a ground test rig it doesn’t look like a one-off, especially as this one was new in its box.

The prime purpose of the panel looks to be to select Supply No 1 or Supply no 2 to each of those systems. What aircraft was fitted with duplicated supplies?

Andy

Judging by the size of the fuse boxes, that’s a large panel!

I can’t bring to mind an aircraft which had all those systems, unless the Lincoln was intended to have them all at some point?

What’s all this Power Supply No. 1 and No. 2 business?

Could it possibly be from some kind of ground test rig?

thanks John,

EFU6969 1A is stamped very small on the side and coloured in white
(N)

found more on rear of panel, again very small

EP6970A and an inspection stamp (AW485) looks like Armstrong Whitworth

Don’t think I’ve ever seen one fitted to a Stirling, open to be educated otherwise.

Any markings or ident marks (ARI etc)

John
