摘要: An air-pressure head for determining parameters of an air flow, flow of other gases or fluids, as well as parameters of flight of the aircraft wherein the air-pressure head includes a multi-edged rod, whose edges are oriented in the longitudinal direction of the rod, having groups of orifices between the edges on smooth lateral surfaces of the rod which are connected via pneumatic ducts to outlet nipples disposed off the air flow. The edges in the longitudinal direction of the rod are continuous and the number n thereof is such that n
