Be sure to watch the whole thing.

Cool! Is it supersonic?

Oh yeah. It was a Mach 2 aircraft.

how did it back up ? ddint think fighters had reverse thrusters.

Airliner engine with an afterburner.

That is a wild looking aircraft. I can't figure out how it backed up either. It has to have a cascade vane T/R system.

I just watched it again, this time I think I saw clam shell doors, but still used the side openings. It's a very cool idea.

Viggens were bad ass planes for their day....hell even now they are pretty freckin awesom

some kind of rotating nozzle or vents , plus it took of in such short space that it must have some hidden somewhere.

It has a clamshell thrust reverser in the housing at the rear of the aircraft. The clamshells close, and direct the jet's exhaust forward through the vents in front of the housing.

The turn on the runway was more impressive than a short roll when light and no externals.

That's what I thought I missed the first time I watched. How old is this thing? I like that the canards had aflap position too.

Thanks for the link. I can't believe its that old and have never seen one before.

I had a die cast one as a kid. I've always loved the looks of them. I had no idea it cold reverse like that... pretty flippin' awesome.

Me too! I loved that plane

Why do people make such

statements when it comes to aviation (and motorcycles)?

The Viggen was powered by a single Svenska Flygmotor RM 8 turbofan. This was essentially a licence-built variant of the Pratt & Whitney JT8D engine that powered commercial airliners of the 1960s, with an afterburner added for the Viggen. The engine also incorporated a thrust-reverser to use during landings and land manoeuvres, which, combined with the aircraft having flight capabilities approaching a limited STOL-like performance, enabled operations from 500 m airstrips with minimal support. The thrust reverser could be pre-selected in the air to engage when the nose-wheel strut was compressed after touchdown. Only the Viggen and the Panavia Tornado featured both afterburners and thrust-reversers.

And where did the JT8D come from?

The Pratt & Whitney J52 is an axial-flow turbojet engine built for the US Navy, in the 9,000 lbf-class. It powered the A-4 Skyhawk, A-6 Intruder and EA-6 Prowler.

Within Pratt & Whitney it was designated JT8A, and provided the basis for the Pratt & Whitney JT8D, the most popular civilian low-bypass turbofan engine.

I would make sweet love to a saab viggen if I had the opportunity (the flying kind).

I love those planes and would be happy to never touch a gun again if I owned a functioning specimen of one of those.

The engine portion of that article is full of fuck and fail.

Saab had originally wanted the Pratt & Whitney TF30 as the Viggen powerplant. Since the engine was not finished in 1962 when the airframe vs. engine design size needed to be frozen, the civilian variant of the TF30 - the JT8D was chosen as the basis for a Volvo Aero modification instead.

The fucking TF30 never had a civilian version, it was built as a military engine and was used as a military engine.

The JT8D was based on the J52.

My apologies, Sky King!

I know -I- didn't write it!

Designed to operate off of improvised airfields in case Sweden ever got in the middle of a war between the USSR and the USA. Awesome aircraft. They were still operating it until recently.
