DYNAMIC PRESSURE MEASUREMENT SYSTEM CAPABLE OF ACCURATELY MEASURING DYNAMIC PRESSURE AT A CONSTANT SPEED SET IN ADVANCE

摘要

PURPOSE: A dynamic pressure measurement system is provided to accurately measure dynamic pressure at a predetermined speed as a dynamic pressure converting valve, which is applied to a system for observing dynamic characteristics of the pressure as a high-speed valve for converting dynamic pressure, is controlled to be opened by using electrical signals.;CONSTITUTION: A dynamic pressure measurement system comprises an air generating unit (110), a primary air pressure storing tank, a main air pressure storing tank (140), a high-speed valve (150) for converting dynamic pressure, a dynamic valve speed controlling unit (160), a dynamic pressure sensor (170), a dynamic pressure sensor processing/analyzing device (180), and a main exhaust gas (190). The dynamic pressure generating unit generates air pressure by using air to generate dynamic pressure. The air pressure generated by the air pressure generating unit is supplied via a first supply valve (119) and charged in the primary air pressure storing tank. The pressure charged in the primary air pressure storing tank is charged in the main air pressure storing tank at a pressure level desired to measure with a pressure controller (130) via a second supply valve (129). The high-speed valve for converting dynamic pressure is opened and closed repeatedly at a predetermined cycle so that the pressure charged in the main air pressure storing tank is transferred at a predetermined speed. The dynamic pressure valve speed controlling unit controls the speed of the dynamic pressure by controlling the opening/closing time of the high speed valve for converting dynamic pressure.;COPYRIGHT KIPO 2013
