Aerial propellers more especially for aircraft propulsive units |
摘要 |
The invention provides improvements to aerial propellers, particularly for aircraft propulsive units, wherein the cowling of the propeller is defined by a meridian line having: at its origin (B) a maximum curvature greater than 15; then a curvature decreasing rapidly from the maximum value to a value of 7; then a curvature decreasing linearly from the value 7 to a value of 0; than a curvature decreasing more slowly from the value 0 to a minimum value between -3 and -5; then a curvature increasing rapidly from the minimum value to a value of 0.
