AIRFOIL ATTACHING AND DETACHING METHOD FOR WIND CHANNEL TEST MODEL

摘要

PURPOSE:To increase connection strength, to evade deformation due to heat, and to replace airfoils by wedging rectangular projection parts of the airfoils long sized holes of a body part, and thus positioning he airfoils and body part and engaging a body rear part threadably with the body part. CONSTITUTION:The airfoils F1-F4 are fixed to the body part 2 by rotating the body rear part as shown by an arrow while the rectangular projection parts P1-P4 are wedged in the long-sized holes H1-H4, and moving a key S as shown by an arrow (a), thereby wedging the key S in key grooves K1-K4. Consequently, the connection strength is increased as compared with adhesion and soldering. Further, no heat is required unlike the soldering, so there is no problem about deformation the due to the heat and deterioration in heat treatment. Further, the airfoil shape is changed as experimental conditions change, only the airfoil can be replaced.
