Title: Bristol Brabazon I
Post by: finsrin on August 24, 2019, 05:20:58 PM
Got a surprise local 'deal' on 1/72 Bristol Brabazon.  Less than half lowest Ebay price.  In reality they work but to me props appear small for such a large aircraft.  Am considering concepts that at least look to have more power.  Starting with two concepts.

1 >> Add under wing jets outboard of props.

2 >> B-36 wings match well to OOB mounting positions on fuselage.  Looks doable.

Plan to check fit of 1/48 B-29 wings.  Drawback to them is cutting out engine mounts and filling hole.  Next install alternate engines.
For now is a contemplation exercise.  Have three involved over half done builds to finish first.

Looking forward to this

In the Brabazon book I have, the second one that was getting built when it was all cancelled, was to be powered by turbo-props Bill. And it would have got 4-wheel trucks/bogies for the main gear. I was going to buy a couple of the Execuform kits to do the two versions but I missed out on the chance to get them when Mike Herryll retired and shut his operation down.

Indeed, the Mark II was to be powered by eight Bristol Coupled Proteus turboprop engines – paired turboprops driving four-bladed screws through a common gearbox.  This would therefore have changed the coupled Bristol Centaurus radial engines nicely show n in the below diagram:

Which incidentally also were used to power the Saunders-Roe SR.45 Princess:

Thanks guys.  When build time comes thinking to finish as 1950s-60s MATS to go with C-47H.

Some other ideas for you:

Finish as normal operational airliner, perhaps as an alternate to Lockheed Super Constellation in schemes of BOAC, QANTAS or others?
Do as something equivalent to EC-121?
