Little known / experimental aircraft

The Junkers JU-86R, a high altitude reconnaissance airplane. Able to reach 47,000+ feet, it was powered by a pair of Junkers Jumo 6 cylinder turbo diesels.

The story of WW2’s highest altitude engagement:

While looking at high altitude records for manned propeller airplanes, I came across the German Grob Strato 2C which achieved 60,000 in 1995.

It featured 2 pusher Teledyne Continental 6 cylinder piston engines that were combined with the gas generators of 2 P&W PW127’s. Very odd combination- Ike? Sevenhelmet? Can y’all explain the benefits of this engine setup?

Many of you by now saw the video of the Rotax powered Carbon Cub making it to FL 350. If not here’s the video…

 
They used the gas generator from the PW127s to provide a constant supply of pressurized air to the piston engine at high altitude.
German innovation at it's finest.
If they had the access to raw materials like manganese to provide the metallurgy it could have been a very different war. That isolated industrial capacity was probably the single biggest overwhelming advantage we had over them.

Probably a lesson to apply to current events in there….
