Abstract : A description is given of a patent for a plane aerodynamics chamber for blowing through sections of the type of flat gratings consisting of plane vertical and horizontal movable walls, a parallelogrammic mechanism for changing the section of the working part, and a device for controlling the parallelogrammic mechanism. Disks are set in sockets of the vertical walls and connected in hinge fashion with the horizontal walls for the purpose of smoothly changing the section of the working part. Another distinguishing feature is the use of two self-braking worm pairs and a hand drive whose purpose is to precisely set up the investigated object in relation to the working axis and to avoid accidental turning of the disks.
