ANORDNING FOER KRAFTALSTRING I EN STROEMMANDE VAETSKA.

摘要

An elongated body has a rounded and symmetrical profile. The profile defines a rounded and elongated leading portion (110a) whose thickness increases from the front to the rear and a rounded trailing portion (110b) whose thickness decreases. The maximum thickness of the profile is between 50 and 100% of its length in the direction defined by its axis of symmetry. The trailing portion has a section formed by a circular arc smaller than a halfcircle. The remainder of the profile has a shape smoothly joined to the circular arc. The system sucks the fluid into the body in an area located on a first side of the profile toward which the force is to be produced.
