ANALYSIS OF ATMOSPHERIC TURBULENCE FROM MISSILE FLIGHT WIND MEASUREMENTS
ARMY ORDNANCE MISSILE COMMAND REDSTONE ARSENAL ALA
Pagination or Media Count:
The split of an instantaneous wind profile into its mean quasi-steady profile and its nonstationary components is discussed. It is shown that two mathematical conditions can be established for this separation procedure. First, the sum of the remaining fluctuations must be zero, if the variations represent turbulence. Secondly, it may be postulated that the first lag correlation be positive, and the second one negative for a 23 point analysis. The separation of the mean profile from the turbulent part is demonstrated on hand of an example for data of the JUPITER Missile Flight 30 between 400 and 3000 m altitude from 12 m height interval recordings.
