Now that's the attitude I like, maybe someday we WILL have a Typhoon in the air. Like I said, if you can dig up a P-38 in the ice, you can do anything. ... keep dreaming ... :D

Yes thats true, but the one major difference between Tiffy and Tempest was the Typhoon had a large wing root, I think 5 or 6 inches thicker than Tempest, I believe this was due to the CG issues with the weight of that huge Sabre engine and also the initial design had 6 MG's per wing.


Eh?

The Typhoon was the first all-metal monoplane Hawker, or Camm if you prefer, had designed. Sure, the Hurricane had metal covered wings from fairly early on but they were originally designed with a fabric covering.

The Typhoon was supposed to be the next generation of fighter with nominally twice the power and twice the weight. For Camm, it was a step into the unknown and it's easy to understand him going for a very thick and strong wing. I have a feeling that I've read there was some input from the RAE at Farnborough with regard to the wing but I'm not certain.
It was certainly realised very soon that it was too thick and design of what became the Tempest wing started.

Most of a Sabre would be probably relatively easy to remanufacture, given a bottomless pit of loot. However, the only way of making the sleeve valves that gave the necessary stability was centrifugal casting. I was told some years ago that they were made at a factory just down the road from here. I've no idea if they still had the capability but as they closed down a couple of months ago they certainly haven't now.

Hiya Cvairwerks.I agree mate,we use 3D design software (ProD and some Solid) to do the majority of our project (click on sig).Beauty of it all now is,it,s faster,more available,easy to edit,more usable,and darn more fun these days.A design can be sent IGES via email across the world where it can be viewed instantly.Plus the costs of 3D printers is coming down so parts can be prototyped quicker and cheaper,ideal for casting Masters.
A ground run Tiffie or Tempest will be my wish and all the "bugs" in the original design could be found and squashed easier in the computer.As you say it all comes down to the moolah..


I'd agree that we could see the employment of new technology in making a 'new' Napier Sabre. The quick assumption that the Sabre's issues could be bugs to be squashed with computers might prove true. The fact remains however that the Sabre is a very, very complex engine with a lot going on, and at the top end of piston-engine development - there's a lot of things going up and down and round and round, and it may be that a high failure rate simply cannot be avoided.

I dunno, I'm no engineer, but some stuff's too complex to make failsafe.

A ground runner would be interesting though, I agree.

It would at least be cool to see a static one built.

Building a single static example seems a bit pointless as we have original authentic Typhoon and Tempests...

You are right. Who would have predicted seeing Me 262s in the air ever again? Even 15 years ago?

I´ve seen new cast motor blocks for expensive classic cars made from scratch using 3d software and rapid prototyping, and thats just for a run of a few units. And car parts are just chump change in terms of cost when compared to aircraft parts! Its all becoming much more affordable and do-able. Saying anything simply "can´t be re-manufactured" is laughable.
