Most German bomber aircraft were powered by Jumo211 engines. Did they use reduction gears?
- There were plenty of Jumo211 engines available by 1941.
- The Jumo211 was reliable.
- The Jumo211 was fuel efficient.
Do you have the cost figures?- The Jumo211 was relatively inexpensive to mass produce.
- The Jumo211 was more powerful then the P&W R-1830 engine which powered most U.S. 4 engine bombers. Therefore it should have been plenty powerful for the new Italian heavy bomber.
A nice looking aircraft. However I have read that the radial engines were unreliable. Maybe they should have just used 4 x Jumo211 engines.
How can that be when American B-17s and B-24s were powered by 1,200 P&W R-1830 engines?
people are still arguing over the exchange rate of the Euro to the Dollar or the Chinese Yuen to the Dollar and if they are artificially high or low and by how much. trying to compare prices based solely on exchange rate is highly suspect.Regarding Jumo211 engine cost......
1941 prices. per Olaf Groehlers GdLk
131,175 marks. Ju-87B with engine.
100,300 marks. Ju-87B without engine.
------------------------------------------------------
30,875. Cost for Jumo211 engine.
$12,350. Assumes 2.5 marks per American dollars.
For comparison purposes.
$25,000. Packard built RR Merlin engine.
$19,000. Allison V-1710 engine.
$11,188. DB601 engine (27,970 marks).
WWII Germany clearly knew how to mass produce liquid cooled V12 aircraft engines at low cost.
Why would you keep the Italian prop if you are going to use a Jumo?Not without some serious reduction gears.
It is torque that turns propellers and there is no way that a 35 liter engine is going to compete with a 53 liter engine on that score.
may Krieghund will show us what is on the next page.

The P.108A carried out a series of trials at altitudes between 1,500 and 4,500 meters. That's about where a WWII era level bomber should be operating if you want to hit anything.
