DEVICE FOR MEASURING TOTAL AND STATIC PRESSURES IN UNSTEADY GAS-DYNAMIC FLOWS,
Abstract
The object of the invention is a device for measuring the total and static pressures in unsteady gas-dynamic flows which contains pickups fastened to a forked holder in one of which at the end or face part and in the other in a lateral flow-through piezo elements are located. To increase the dependability of the device and to reduce the temperature errors in measuring in it the piezo elements on the outer side are covered by heat-protection plates with acoustic impedance of the piezo elements. These plates serve at the same time as electrodes of the piezo converters. (Author)
