Temperature Altitude

[bigj_16]

There was discussion on the UOA section about altitude, etc. I ran across this paper. Has a a lot of different interesting points in it. I would assume it is about drone engines. http://www.dtic.mil/dtic/tr/fulltext/u2/a576150.pdf

Believe it or not this was written when Obama was in office he must have missed this "“Praise God from Whom all blessings flow.” .

Well, this is about high altitudes

Good paper, but no surprises - less dense air from high altitude causes power loss in NA engines. That's why they were supercharging WWII aircraft engines in the 40s.

Thanks for posting! Trust me, there is a significant power loss at high elevations. I live at 5,600 feet. When I lived at sea level, truck was awesome! At least fuel injectors compensate, people with carbs, well they are adjusting at various elevations. I physically run at various elevations and your lungs feel it. Especially in Santa Fe 7,500 feet or the Sandia Mountains 10,0000 feet. Your body develops a lot of red blood cells to adjust. Respectfully, Pajero!

What about JP-8 in SI engines?
