Re: MBB LART

Note that the picture shows an early version of the SAENGER II TSTO (which, contrary to the article text, had airbreathing turboramjets in the first stage) rather than LART, which was an SSTO with an airbreathing rocket engine.

Re: MBB LART

Perhaps confusion with Sanger projects of Sixties?

Anyone got a picture of LART?

Ok, I'll bite: "LART"??
Liquid Air Rocket... something? Not familiar with the acronym...

Re: MBB LART

Think German!


LART = (Einstufiger) LuftAtmender Raketen-Träger

LART was a MBB/ERNO airbreathing horizontal takeoff / horizontal landing single stage to orbit proposal from the mid-1980s. Largely similar to the BAe HOTOL.

Manufacturer: MBB. Core Diameter: 28.00 m (91.00 ft). Total Length: 66.30 m (217.50 ft).

Oh sure, blame a 'fer-in' language and all... next you'll try telling me that it really is "OTAN" and not "NATO" on one side of the plane simply because someone got lazy and just did a "cut-and-paste" without reversing the image...

Re: MBB LART

The 'core diameter' given in the Astronautix site is really the wing span. Attached is a (unfortunately fairly crude) picture of an early configuration.

Re: MBB LART

I look in archive and found some stuff

That Spaceflight News Picture show older Sänger version
MBB was studies around 1987
Sänger 01/51 turbojet + Ramjet + Rocket engines
Sänger 05/51 horizontal take off
Sänger 11/01 Ramjet + Rocket engines
Sänger 12/61 Rocket engines vertical take off tandem
Sänger 16/51 Sled, Ramjet + Rocket engines

LART Baseline - 275 tons takeoff weight, 10 tons payload, crew of 2
Alternative design
210 tons takeoff weight, 7 tons payload, crew of 2
400 tons takeoff weight, 15 tons payload ,crew of 2

Dan - Did you have any success with finding more info on LART counterpart from MBB?

If not, I think I have at least one brochure in my files, but it will take some digging...

Any further information on LART would be appreciated. In writing this book, my focus has been on getting the story of Hotol right - and describing the many different variants and projects directly associated with it (outlined above). It's a Hotol book - perhaps THE Hotol book since there aren't currently any others!

While I intend to provide an overview of other systems, it won't be in tremendous detail - just enough so you can see how they fit into the Hotol story. I asked the surviving Hotol team members, for example, if they remembered LART - and they didn't.

It would be incredible to get a full book on Saenger and all associated systems (Deutsche Raketen-flugzeuge und Raumtransporter-Projekte by Koelle, Sacher and Grallert, while it was written by the people who worked on Saenger, doesn't really tell its story - it's more of a technical paper disguised as a book, and it doesn't mention LART either as far as I can see).

Luc van den Abeelen did a great job with Spaceplane Hermes and JC Carbonel provides an excellent overview of Hermes in French Secret Projects 3, with more emphasis on associated and competing systems. But Saenger and NASP haven't yet been given comprehensive coverage (again, as far as I can tell). Ditto Hope-X.

And as I said, if Reaction Engines could be persuaded, it would be interesting to see a book solely on Skylon. They don't seem keen on that however and Alan Bond, though he's been massively helpful with my book, hasn't been with the company for a long while now.

Attached are the raw scans of all pages of the LART brochure.

Thanks for the effort, much appreciated !

That's tremendous - thank you. I was about to post that the final chapter of the book - Hotol's major contemporaries - was now finished at around 13,900w (4000w on Hermes, 1600w on NASP, 4300w on Sänger and 4000w on Skylon - taking the overall word count without the introduction, appendices etc. up to 144,000w) but I might now have to squeeze some LART in.

I am, incidentally, leaving out HOPE-X, Hyperplane, Star-H, DC-X etc. because they don't really feature in the Hotol story - whereas Hermes, NASP, Sänger and Skylon are all much more Hotol-adjacent in one way or another.

LART, being effectively the German Hotol, probably deserves some coverage.

I converted the LART scans to pictures and rotated them.
