gripen news

[simmie]

some of you, if not most probably, will know this little titbit of news that I picked up from Flight International (27/06-03/07).

SAAB are studing new gripen variants, including:-

re-engining with the F414 (increasing power by 25%), with larger fusalage barrel, new intakes, increased fuel capacity and new nose gear.

and

a carrier variant as a candidate for the Indian Navy, but ould also be offered to the Royal Navy in the event of JSFdisappearing up it's own jet pipe.

Models are expected at Farnborough this month.

[simmie]

forgot to say, in the same issue it is state that Boeing is pushing the C17 hard so as to extend the production run and maintain the rate at 15 aircraft a month.

they are hoping that the USAF will buy an additional 300 B models.

With Canada expected to commit to 4, and 4 for Australia.  Boeing hope that Sweden will take 2 and Holland and Nato may take some as well.

Any Gripen-related news is good news: thanks for sharing.

Italeri modifications, anyone?

[Ollie]

Go for it Barry, so that as soon as you are done, the new version is kitted.

Would this happen to be the Gripen-N that was being pushed to the Norwegians a few months back?

In Tony Buttler's book British Secret Projects-Jet Fighter since 1950, there's some three view drawings of the BAe P106 and P112.  When I first got my book I did a quick flip through to see what was in it and when I saw these two aircraft I thought it was the Gripen and a derivative.  Reading about it though I found that BAe designers were intrumental in the design of the J.39 and used a lot of the design of the P106 and P112 in the J.39.

I thought that this would make a nice project to reverse a Gripen kit back into one of these two so I contacted Tony Buttler and asked if he had some other drawings of these aircraft.  He very kindly sent me some three view drawings of both of them.

Some observations I've made of the Gripen has led me to the conclussion that the Gripen (through the P106 & P112) is really an advance development of the Hunter.  To prove my point I bought the Revell Hunter and an Airfix Gripen and found that if you lay one fuselage half from one kit over a fuselage half of the other some startling facts come to light.  The fuselages are both the same size in length and depth and diameter except the J.39 has a more pointy nose. The way the canopy bulges is almost identical.  The fin in relation to the cockpit is in the same place. The fin of the J.39 is almost identical to the Hunter's where the J.39 is squared of at the top but the forward and rear rake of the fin is the same.  The undercarriage is almost in the same place on both aircraft.  The air intakes work the same way except the J.39 had extended air boxes.  The only real difference is in the wings which is why it's an advance development.

Some pause for thought don't you think?

THREE HUNDRED!!!!!!!

I can't believe that.  They only have what, 180 now!

C-17s kick donkey, but they cost a fortune.  I'm pretty certain the USAF would rather have 100 extra Raptors than 300 C-17s.

Interesting observation Robert. You should check out Tonys Article on SAAB published in Air Enthusiast at some stage as that covers the development of the Gripen.

Yeah, call me a penny-pinching, pansy-donkey, pollyanna liberal, but I think $202 million (af.mil, 2006) for an airplane that DOES NOT GENERATE REVENUE, for an airforce not faced with a substantial airborne enemy, a bit much...

Sincerely,

Joe Taxpayer

I would like to see that Geoff, do you have an idea what issue it might have been?

Well... There are probably some things similar, as you pointed them, but there are surrely a LOT of differences!

But after all, that makes sense... In the same way, the Rafale is an advanced development of the Mirage III !!
Indeed, Dassault used its works about the Mirage III when they designed the Mirage 2000 (same general appearence, but different wings, longer and deeper fuselage... Well, bigger and better!!)...
And for the Rafale, Dassault partly used its works on the Mirage 3000 (a twin engined Mirage 2000 with the Tornado's engines) and the Mirage 4000 (a scale up Mirage 2000) for the design...
In fact, the first view of the ACF (futur Rafale) shown a plane that reused the Mirage 2000's wing concept, the tail, the Mirage 4000's nose and cokpit... Even the air intakes were very similar to the Mirage 2000's, with cones but putted down in order to add the canards...

What I think is that when the designers find something good on a concept, they surrely will re-use it for future development or futur aicrafts, concentrating all their efforts in the resolution of the problems they ignore the solution...
That sounds logical...

Sometimes, it's fun to trying to find what we French call the "air de famille":
-B-2A and N-1M
-Rafale and Mirage familly
-B-52 and Boeing 367-80
And now, I learned that the Hunter and the Gripen are from the same family

[NARSES2]

At the SIG meet Lance had a Draken, Viggen and Grippen all lined up. You could really see the family resemblence that way. Never noticed it quite as clearly before. "A picture (or model) speaks a thousand words" ?

PD7,

If you look, the 367-80, the ancestor of the 707 et al., was a development of the basic Model 367 "Stratocruiser" which in turn derives from the B-29.  It could be argued that the 707 is the blending of the Stratocruiser line of development with the B-52 line of development.
