THE SMOKE-TRAIL METHOD FOR OBTAINING DETAILED MEASUREMENTS OF THE VERTICAL WIND PROFILE FOR APPLICATION TO MISSILE-DYNAMIC-RESPONSE PROBLEMS

Abstract

A METHOD IS PRESENTED FOR OBTAINING A DETAILED, ACCURATE PROFILE OVER A LARGE ALTITUDE RANGE. The method utilizes photogrammetric measurement of successive positions of the trail of an ascending rocket. Construction of a rocketborne smoke generator is discussed and the photography, film reading, and data-reduction procedures are described. The accuracy of the method is examined and error equations are derived. Examples of wind profiles measured by this method are shown, and their implications for missile response are indicated.
