Saab Gripen

[elmayerle]

With that proviso, i'll agree with you, PD7, the Grippen is what the F-20 should ahve been.  *chuckle* Actually, it comes damn close to one of the proposed F-20/Lavi hybrids that was studied as a joint program 'twwen Northrop and IAI with the intent of reducing the cost of the Lavi.

Exactly!! That's the right formula! I didn't remember how to say that in English, sorry for the mistake.

Hum... I never heard about that. But it gives me an idea!
What about a variant of the Gripen developed with... Israel??

I always loved what the Israelis did (or planed to do) to their Mirage and Phantom derivatives, so why not a Gripen one!! Only for the desert camo and the cool Python missiles!!

PD7, I'd be tempted to call the T-50, esp. if they do a single-seat variant, the F-20 ofthe 21st century since so bloody many of its systems trace back to the F-20 (engine, radar/fire control, etc.).

Actually the Taiwanese F-CK-1 should probably be the first one to bear the title.

But then of course, T-50 fits the title even better.

There was a plan for mating F-20/Lavi hybrid?  That gets the imagination going!

I remember seeing on an ancient issue of Air International (or was it Air Force Monthly?) magazine a JAS-39 article that had a line drawing showing the evolution of JAS-39's configuration (before it became the tailless deltawings with canards that we all know).

Does anyone have drawings showing those proposed configurations?

instead of starting a new topic, i looked up this old gripen topic.
this idea him me at work today 
wonder if there was an alternative to the harrier, F-35 and YAK141

with the F-35 Lightning II development now under fire, particulary from british side, why not transfer the STOVL technology of the F-35 and build it into the Gripen.
the gripen has proven to be a nice agile fighter with many possibilities.
so i wanted to tranfer the F-135 STOVL/lift fan engine into a JAS-39C/D gripen (the newer gripen NG would be to heavy)

then the design i came up with was the JAS-39V Verti-Gripen.
i think these could equip the carriers of the Royal Navy and maybe even encourage the Swedish Navy to aquire a carrier, maybe buy off the RN's Illustrious as she is currently kept in reserve

*chuckle* Nils. both Lockheed-Martin and Yakolev found that a back-hinged door for the lift-fan/lift-engines works better (that's one of the most noticeable differences between the X-35B and the F-35B).  You'd have some "interesting" changes setting up lift fans like the F-35B uses since that uses a shaft-driven lift-fan that is driven by the engine directly (in some ways, it's an extreme form of the driveshaft for the AMAD gearboxes most modern combat aircraft are fitted with).

In a past thread regarding the BAe P.112, you mentioned a "'three-poster' with PCB" arrangement as the simplest VSTOL engine installation.

(And I figure that a VSTOL JAS-39 might be viewed as a revival of BAe P.112......)

Two questions:

1. would you describe this "'three-poster' with PCB" arrangement?

2. is comparison between the "'three-poster' with PCB" arrangement and the one adopted by F-35B possible?

Imagine an RR Pegasus with a single central nozzle at the rear instead of the split exhaust. PCB=Plenum Chamber burning, i.e. afterburning in the nozzles.

This arrangement was planned for the Hawker P.1214 and P.1216 projects:

Speaking of Gripens, here is a nice Indian Gripen rendering I was sent today:

Actually, if such a scheme is to be implemented in a Gripen...... would the engine have looked like the one used by X-32?

"Slient Gripen"? 

[Scooterman]

NaoH just sent me this pic.  Dunno where from, but this is too cool not to post.  Plus it's in the sexiest scheme ever.

Now if somebody would just make a conversion for the NG.
