PITOT TUBE FOR MEASURING AVERAGE WIND SPEED

摘要

PURPOSE:To obtain the precise average wind speeds at a plurality of locations, in the pitot tube for measuring the average wind speeds, by connecting the central points of 2n pieces of full pressure tubes each having two holes for measuring the full pressure, connecting the tubes to one pressure takeout tube, and separately providing a static tube. CONSTITUTION:The central points of the two full pressure tubes 32 having the two full pressure measuring holes 31 are connected to the first connecting tube 33 for communicating a pressure, at an angle of 45 deg.. The number of the pressure tubes 32 is 2n, where (n) is an integer. The central points of the two first connecting tube are connected to the second connecting tube 34 at a right angle. The tube 34 is finally connected to the pressure takeout tube 35. The four full pressure tubes are so arranged to form a symmetrical pattern at every 90 deg. angle in the same plane with the takeout tube 35 as a center. The static tube 37 having a static hole 36 is vertically provided with respect to said plane, bent at the edge of the second connecting tube, and aligned with the takeout tube 35. If said plane is faced against the wind, the setting is easly, the directional property is excellent, and the average wind speeds at a plurality of locations can be cuncurrently measured.
