摘要

The aerodynamic brake has a blade holder (4) whose one end (41) is connected with a blade (3) that is rotatably connected with a central tube (2) around longitudinal axis. Other end (42) of the blade holder is connected with the central tube. The blade holder is formed of partially deformable profile structure in cooperation with the blade. The blade holder is made of stainless steel and formed with slots (9).
