How to Correct Measured Thrust for Density Altitude?
Suppose I run my engine on a stand and get a number different from the mfr specs when it comes to max thrust...
The same engine in the same installation might put out more than specified on a cold day or less on a hot day because of the air density, making it impossible to make apples to apples comparisons between different engines or even when comparing the same engine from one day to the next.
Can someone provide me with a formula to correct measured thrust for air density, so as to derive a thrust value which has been corrected to a "standard day"?
Many thanks,
Don Ray
