This article deals with design and partial realization of experimental aerometric system for general aviation. The height is determined by the barometric principle. However, the primary measurement of the pressure is performed by differential pressure sensor which is added by a low-cost absolute pressure sensor. This system allows a measurement of height, vertical speed and temperature of the environment...
This paper describes a differential resonant pressure sensor formed by a ferromagnetic cylindrical resonator with electromagnetic excitation. The frequency of the resonator corresponds to the pressure difference between the inner and outer space of the resonator and the level of absolute air pressure on which this difference is created. The sensor can therefore be used for measuring air speed, and...
• Sensor evaluated by DRUCK GE6000 Automated Pressure Controller • Wind tunnel tests • Total port almost independent on AOA(and AOS) • Probe head dP/Pc ratio reaches 1.6 • There is negligible deviation between the probe measurement system and laboratory measurement instruments • The total absolute error after calibration is +/− 6 Pa • Two ways of mounting
This article describes a design of a probe intended for aero metrical instrument testing which is being hanged under an airplane. The probe collects data in an undisturbed airfield and compares them with data provided by dashboard instruments. The differences reveal quality of an airplane prototype design during maiden flights. The most important flight instruments are an altimeter and an air speed...
