Abstract

Wind tunnel tests were implemented for experimental verification of the reversibility theoremfor three various shapes of fore body for an axially symmetric thin body in direct and reverse streams. Besides,such tests were implemented for UAV models with three types of wings. Results of investigationsshowed that the error of execution reversibility theorem consequence can achieve 12.5% at the range ofangles of attack from 0 to 20° (accordingly, from 180° to 200°)
