PRECISION PNEUMOMECHANICAL PRESSURE TRANSDUCER FOR MEASURING FLIGHT VEHICLE ALTITUDE AND VELOCITY

摘要

The operation and projecting physic-mathematical bases and projecting features of precision pressure transducers with pneumomechanical resonator for measuring flight vehicle altitude and velocity are considered. The new base functional scheme building of such device for unlimited increase its upper limit is propose. The decreases devices temperature errors means under two oscillation modes excitation of new (many-leaf) structure resonant element is described. The making order of redundant design resonant element model is take out. The precision (with error at 0,03% level) measuring pressure in broad range possibility is estimated.
