Can I ask a (maybe stupid) question, but why are there only 5 exhaust stacks?

Mike

Not at all ….on the Merlin 25s which I understand were the main Merlin used on Mosquitos (there would have been others) the proximity of the the wooden wing and nacelles on the Mosquito to the exhaust stubs of the Merlin forced RR engineers to have a two into one stub on the last cylinder of each bank.

It really is a V12 …but just with 10 exhaust stubs !!

I thought that was the Australian Mossie until I saw the jackets!

I don’t get it………

Whatever the markings are or whyever they “made the news”.

Could you perhaps give a hint rather than just post blind unexplained links?

Oh, please old chap………just be a little respectful…….Daniels posts are always a bit interesting especially for us fellow convicts in Australia…….

Excellent news to hear they are taking the poor old girl (A94-959) down off the pole….

HARS tried quite a few years ago to save her…… but strong local opposition from an amazingly, noisy, and aggressive minority called Save Our Sabre group was unbelievable…….at the public meeting sponsored by Council you would have thought we were Adolf Hitler the way we were treated by Save Our Sabre.

As is human nature with these things the Save Our Sabre organization did absolutely nothing positive themselves for the sabre except keep it up the pole rotting for a few more extra years whilst Council were forced to look at a politically more palatable solution.

To see the condition of her look at the photos in ADF Serial Web site of Sabre A94-959 in Series Two aircraft

And here’s another famous tragedy……. due in part to the bad design of the manual release handle of the Scimitar canopy.

Hi Phil,

Just for interest back in 1981 the local Australian branch of the Confederate Air Force landed a PBY-5A on Lake Macquarie at Rathmines.

The nose wheel cam hadn’t centered the nose wheel properly and when the Cat triumphantly motored up the Rathmines ramp it was only on the main gears and the front shackle in front of the nose wheel doors.

No damage to the doors……..but all very embarrassing.

Local crane was called in to lift the aircraft up to then drop the front gear down properly.

Re the earlier comment about F86 Sabre canopies.

I photographed this rather battered (look at the wrinkling of the fuselage and the iffy paint job) USAF Manston-Based F86F of USAF 406th FIW at Biggin Hill during the 1955 Royal Observer Corps “Recognition Day”. The canopy looks fairly conventional and if opened at speed during the ejection sequence I would assume the slip-stream would lift it well clear of the pilot’s head.

Rather puzzling is the absence of the red “Ejection Seat” triangle alongside the cockpit. Did perhaps the USAF adopt the red warning triangle later? R.A.F. Meteors I photographed at the same time (1955) quite clearly display the red triangle.

The front rim of the canopy as it slide back would take off the pilots head from the eyebrows up…….shorter vertically challenged pilots were generally OK……..the RAAF lost 3 pilots to this design flaw before the bolt through the canopy was quickly introduced

I think you need to look at your text and font colour settings, your text is massive and blue, its like you’re shouting with a megafone!

Thanks for the feed back….font size is now smaller

The Vulcan had five crew. It was the Air Ministy specification which only required ejection seats for the Pilot and Co-pilot so nothing to do with bad design as such despite Avro coming up with a proposal to fit seats for everyone (which was rejected).

Hope the Air Ministry bean counters slept fitfully with such an inane, absurd specification…….

Surely the first sentence of the initial post has this argument mis-stated. Being early generation jet fighters, at a time when ejection seat technology was in its infantcy, surely the statement should be:

“Reading the postings on the early 60’s ‘state of the art’ canopy/ejection seat design for the Lightning ………………”

Rather than the 21st Century retrospective view:

“Reading the postings on the archaic canopy/ejection seat design for the lightning ………….”

It is so, so easy to put 21st Century values on designs of 50 years earlier – especially when things go wrong. Sixty years of experience with jet power and ejector seats, constant research and learning from past mistakes make the current generation of aircraft so much safer all-round, but we must be careful when judging with the benefit of hindsight.

Certainly a balanced, thoughtful and not unreasonable response……….and yes you are absolutely right it was a very easy thing to say with hindsight.

However the post was asking for other examples of just plain BAD DESIGN.

Here’s another….can any body explain the logical process which saw a brand new bomber sent into service in the 1950s with two ejection seats for a crew of 4……….the magnificent Vulcan?

Hi Guys here is a link to a large selection of photos of the joint HARS and Lake Boga Teams painting and re-installing the restored blisters on the cat late last year.

Photos show the museum, and various stages of the blisters and painting.
