Northrop F-5G / F-20 Tigershark
« on: June 18, 2007, 09:39:06 am »
Hi,

In 1985 the Northrop designed a new project called F-5S (by that
time),it was proposed as a version of F-5G (F-20) for Sweden,
with 30 percent larger wing,do you know it ?.

If memory serves me correctly, and it's been some 15 years since I've seen the data, the enlarged wing kept the same span but shifted the leading edge forward and the trailing edge aft to get the increased wing area (they may have kept the main structure the same and gone with larger leading edge flaps and trailing edge flaps; I honestly don't remember).  There was another proposal floating around about the time the F-5G/F-20 program started for a version with an enlarged fuselage, powered by two afterburning J97s, and with a wing that retained the same planform but had the span increased sufficiently to add one more stores station to each wing.  Sadly, because this proposal came up through the Service Engineering area rather than Advanced or Preliminary Design, it was ignored.  It also had a stretched fuselage to maintain the basic aerodynamics while getting the wing loading of a two-seater down to that of the original F-5A.

Hi,

The F-5S was a really project,but I can't imagine its drawing.

Thought we'd had a topic already.

Some nice photos from SDASM archive:

Hello
Any one can help me please.
I'm looking for more precise 3-view drawings and fuselage sections (if it's possible) of the Northrop     F-20 TigerShark because I want make a radio controled aircraft of this plane.
Many thanks

I've been there and it is a bit disappointing as a museum.  It's in the mold of many American "science centers," focused entirely on kids and usually emphasizing very basic stuff.  When they get historical artifacts like this plane or spacecraft, they put them on display in well-lit rooms with a small sign saying what they are, and that's it.  No context or explanation.  Nothing.  If you want to know more about the plane, or the spacecraft, you'll have to go look it up on the internet, because you won't find anything useful in the museum--er, "science center"--itself.

Well it after all a scientific museum instead of aviation! ::)
Possibly from the point of view of scientists that the plane that the butterfly all one and too... ;D
Therefore F-20 also looks as the caught butterfly! ;D
(Well or as the big model of the plane suspended on a thread under a ceiling)

They could have at least tried to make the fake nozzle a little more accurate. However, it is nice to know the plane still exists.

That is not a fake nozzle, and as it is original flight hardware, it is by definition, accurate.  What you are looking at are the flexible "fingers" that provided the aerodynamic transition between the fixed fuselage structure and the F404 nozzle assembly (which is missing from the display as the F404 for this jet went back to GE).

By the way accident F-20 in Korea has been removed on video....

Similar on that that at it has occurred pompage the engine (see flash in a nozzle?)
that was fatal at such height...shocking shots! :o
