SAAB LX

[Matej]

Browsing the net, at unicraft web page I found one project that I know nothing about. Is there any info about "SAAB LX" ?

Hi Matej,

I have some informations about it,but is not available now,because it is in anther
house.

That's the Saab LX design by Sixten Sason, circa 1941. There was an article on it (where the drawing undoubtedly originated) in the August 1998 issue of Aeroplane Monthly. Supersonic, turbojet with liqquid rocket, supersonic and armed with 12 photocell-guided rockets.

A suggestion, however: take references from unicraft with some skepticism. For example, on their "German future releases" page, they show this:

And call it a "German VTOL Project."


ERRRRR. Wrong. It's an *American* VTOL project, patented by L.H. Leonard... filed in 1943, granted in 1949. It preceded the German Triebflugel. See it here:

In Aeroplane monthly,

That aircraft was a single seat crankel-delta-wing interceptor project powered by
two turbojets with additional liquid-fuelled rocket engine for take-off boost and a
smaller forward-facing rocket for deceleration on landing,(the last was very strange
idea).

Thanks guys.

It seems that in Sweden they are applying this philosophy in almost every fighter design. I have also another great suggestion for extremely short landing - pull the nose of the plane 90 degrees down ;D

Wasn't there an article, complete with at least a 3-view, in Aeroplane Monthly several (perhaps as much as 20) years ago?

Ahem:

The Aeroplane Monthly article gives notice that Sixten Sason
started work with the SAAB aeroplane division in early 1940
were he drew aeroplane and gyrocopter designs.

Is there sombody who haves ever seen other designs by Sixten Sason?
A WWII issue of Der Deutsche Sportflieger mentions an advanced
fighter design of tail first configuration...

That's exactly what I was looking for. Thanks!

better quality LX sketch

Very spectacular rocket/missile storage configuration!

Thanks for the enlightenment about this program.

What... the heck... is that project ? is it serious or not ? what an awesome looking machine !

 

[galgot]

There is even integrated braking rocket motors B) very cool design.

If this truly is a 1998 drawing, the author did his research, as this is exactly what Saab was projecting around the early 1950s. Not to mention the choice of words used are also period correct (sort of).

Saab was projecting that future interceptor needed rocket armament, preferrably integrated into the aerodnyamic body or wing via tubes, 75 mm in caliber for guaranteed one-hit-kill probability against strategic bombers. Folding fin rockets were in development at the time and it was suspected they could be turned into guided missiles in the near future. The missile scope seen is also period correct for Saabs early missile guidance systems without radar. Rocket engines were also experimented with, etc, etc.

That ultra-low aspect-ratio planform would provide low drag at shallow angles-of-attack, but massive amounts of drag at high A.oA.. Those huge wing-tips would produce huge vortices at high A.oA. The only saving grace would be the wing tip vortices colliding along the center-line and cancelling out each other.

See Barnaby Wainfain's low aspect-ratio Facetmobile for more theory.

Third image to the right mentions a STAL engine, this would be the STAL Glan: http://www.stalklubben.org/foswiki/bin/view/STALklubben/GlanProjektet
