RE: How to Correct Measured Thrust for Density Altitude?
Thats just an ADR calculator, he is looking for a correction factor for weather conditions which would already be known.
I did a lot of dyno work on sprint engines and there are specific correction factors but those would not apply to jet engines.
We have run up the same turbines in different weather conditions and there is a huge difference in thrust. We were going to start testing and recording weather and make a chart from that. Not 100% accurate but would get us in the ball park.
From our testing most of them are touting #'s at sea level conditions, I think one mfg gives #'s at 1000' below- LOL.
