Is there a paper model of the Lockheed L-133?

Is there a paper model of the Lockheed L-133 design? I watched a video on it tonight and never knew that the US had a jet powered fighter on the drawing board in 1938. It never got produced but was a very space age design for the time. https://www.youtube.com/watch?v=qpYDeJa0hPQ&t=203s

There are some doubts about the aerodynamics and the engine to be honest, a lot of the unfinished designs have claims of efficiency and greatness never achieved. Other than that they are great conversation pieces.

Yes. There was/is one offered in 1/72 scale for free by e-mail request from here: https://www.sharkit.com/sharkit/freefiles/freefiles.htm It was designed by Der Kampffleiger. I requested mine about 10 years ago but the page is still active so you might give it a try

This Lockheed aircraft concept uses 2 axial flow compressor jet engines. Those compressors were being developed in the USA in the late 1930's by the General Electric company in Schenectady New York with cooperation with the government, NACA ( as well as Boeing, Lockheed and some others ). However, development did not meet any of the WW2 requirement and time tables, and thus the first jet fighters that Lockheed developed ( and also Bell ) were radial flow compressor jet engines derived from the British Whittle units. Those tubby engines saw their popularity peek out with the Gloster Meteor, De Havilland Vampires and the Soviet Mig 15/17 aircraft. Axial flow compressors were superior, however only came to be operational with aircraft such as the F-84 during the Korean war.

This video as they describe is a What if scenario that is 5 years out of sync. It is the US version of the Luft 46 topic.

One major issue from this video that I noted is that the engine air intake is in the nose and so are the gun muzzles. Shooting the guns would have ingested lots of hot gasses and would have stalled the axial flow compressor engines for sure since variable compressor guide vanes were not yet invented. Those helped regulate the flow angle to the rotating compressor blades and minimize detrimental effects.

Finally, I love all these concept jets. They are super fun to research and build models of.

Check out some nuclear powered aircraft of the 1950's and 1960's. That too is a fascinating period of jet aviation.


Thanks for the link and this topic.

There's a simple L-133 paper model offered here ...

https://www.4dpaperairplane.com/lock...3-starjet.html

Looks like many other interesting models on the site too. Well worth a look around.

PS: I just looked through the build photos ... and I withdraw the word simple.
