Abstract: The paper discusses the possibility for creating a pneumatic jet device for trajectory tracking, implemented as a sharp edge channel. The device is based on a full bridge circuit principle, with two constant and two variable throttles. The efficient cross-section of each of the variable throttles blocks partially the channel. Analytical expressions are derived for the dependence of the pressure drop on the device displacement against the channel walls. The static curve is built and the flow parameters are determined for a specific case.
