摘要

The aerodynamic resistance reducing device consists of a shell (4) which can be placed on the towing body (1). The shell has a preset wall thickness (W), and a curved front end (5). One region (8) of the wall is of constant thickness. Another region (9) tapers down in thickness towards the rear edge of the shell.
