‘Never understood this web based image storage. Am I doing something wrong, or are we expected to be satisfied with images like big thumbnails ? Most of us use pretty big screens nowadays.

Anyway…. jolly nice aircraft !

How can you over (or under) rate something that does not exist?

Quite. Gripen exists. I think TooCool was referring to the Novi Avion !

re: engine….
Of course…!….. I forgot the British MOD likes to take everything apart and spend 10-15 years designing obsolescence into it in order to make it cost more. It would be sensible that the 414 engine should remain, and personel trained to work with it.

BTW… The wind tunnel model on the left in Kramer’s picture… Is that not the P.106 ?

Hawker was merged into Hawker Siddeley in 1973, & that became part of BAe in 1977. The P106 concept, which I think is probably what you’re referring to, was produced after that merger.

Yup. It was the P.106 I was trying to remember.

😀 Sign…. Very amusing…. but you are right.,,,, ” no canard ” !

TooCool made a good point:-

“the switzerland is a bit of an exception: a small country, surrounded by countries which have no business going after them and never going anywhere outside its borders, it obviously had no need for a high end solution.. but having the budget they had high expectations. (that last point has obviously changed a bit lately )”

Switzerland used the F-5 for a long time. In my view, Gripen is something like a modern F-5. It was grossly underated, even in USA ! Switzerland also use highway based runways for emergencies. Sweden does too. Gripen is designed for this.

If I had the budget for 22 Gripens, I would not consider buying 10 or 14 Rafales or Eurofighers instead. If I had the budget for 22 Rafales or Eurofighters, I think I would opt for 30 – 40 Gripens. Training pilots to be better for the Swiss environment would probably yield more value in the Gripen, than in any competitor.

It just hit me how ironic the Swiss Gripen acquisition his. Afterall the Swiss designed this two decades ago!

I believe the Brits had an experimental concept, possibly Hawker, that looked a lot more like Gripen does today than the ALR. Anyway, The Swedes made it before anyone else.

Some time ago I tried simulating the ALR, and found it had a pretty horrible interaction between the canard and mainplanes. The Tejas is probably better.

Congratulations to Saab, Sweden and Switzerland !

How about some carrier based Gripens for the British Fleet Air Arm, then ?

Useful program

DesignFOIL is a useful program from http://www.dreesecode.com/

Even the demo version is quite powerful, and you can export coordinates to Excel. This can then be editted into script files that CAD programs can use.

Hudson?

A friend asked me what was in the mud in the middle of this picture. Is that the Hudson ? ‘Pretty deep mud just there !

Leading edge skin structure.

14SWG 0.080 inches 2.032 mm

Very strong at the nose ribs…but perhaps not quite so strong between the nose ribs. 😉

Mark

…. and a butt strap inside, between the top and bottom nose skins.

The grainy photo that caused the dent myth shows the casting at the front of the weapon blast tubes, in my view.

Thanks for the responses.

I heard the Swiss had got rid of quite a few…. some went on lease to Austria (are they still there?), and others went to USA for refurbishment, presumably to end up in DACT training. If Patrouille Suisse are still using them I should head for a Swiss holiday and time it with a display somewhere.

Cheers,

Justin

Short ‘G’ class. I’d then move the family into it, and tour the world.

Stylish!

I think I have been here before, but I am sure I forgot to add a Concorde in my list.

‘Recommend Paul Monforton’s book on the Mk.IX/XVI if you are a serious Spitaholic.

If it doesn’t take off it is a boat…:D

I think in this case it is a boat, but something that takes off without capability of escaping ground effect, is a Ground Effect Machine (GEM).

You are right, Daz. The cameras need the high back space in the PRs, and the pilot needs the extra visibility the R.V. fuselage gives in the FRs.

Perhaps the more measurable differences are in aerodynamics. The high back fuselage most Mk.IXs have probably has slightly lower drag than the R.V. low back that most Mk.XVIs have. I think you will not find a PR Spit with a low back, partly for this reason. I also read somewhere that the slight bulge over the Merlin 266 intercooler on the top engine cowl of the Mk.XVI caused slight pitch instability at high speed.
