Electronic flight data acquisition system for remotely piloted aircraft

Rusiecki T., Skowronek M.

Interdisciplinary Journal of Engineering Sciences

This article presents data acquisition system developed for the use primarily in Remotely Piloted Aircraft Systems. The system consists of several modules which independently function as Air Data Computer, Attitude and Heading Reference System and Flight Data Recorder. Each module works independently from other modules and also provides capability of real time data transmission. The system is capable of wireless data transmission via ZigBee wireless data protocol. The research may be considered as important and valuable due to the fact that it describes innovative concept of “wireless sensors” system. These type of systems are currently only beginning to appear in commercial applications and such wireless systems appear to be a future of metrology in RPAS applications. Features of each module are stated in the article. The prototype device has been tested and confirmed to be operationally functional.

Współczesna centrala danych aerometrycznych to specjalizowany, mikroprocesorowy, lotniczy system do pomiaru pilotażowo-prędkościowych parametrów lotu bezpilotowego statku powietrznego (BSP). W artykule przedstawiono centralę aerometryczną opracowaną w Zakładzie Awioniki i Uzbrojenia Lotniczego, w której ciśnienia całkowite i statyczne przetwarzane są na sygnał elektryczny przez piezorezystancyjne przetworniki ciśnień oraz rezystancyjny czujnik temperatury. Dodatkowo układ ten dokonuje pomiaru aerodynamicznych kątów natarcia i ślizgu.

The air data computer is a special air dedicate microprocessor system, which intermediate estimates the barometric altitude, indicated airspeed, vertical speed, total air temperature, angle of attack and the sideslip from the dynamic and static pressure, temperature and air flow around the aircraft. The air data computer is designed in the Institute of Aviation. The dynamic and static pressures are converted to electrical signal by piezoelectric static pressure sensor (static pressure) and differential pressure sensors (difference between static and total pressure). The angle of attack and sideslip are measured by the flow - direction vanes. The vane measures direction of local flow of air. The processor unit of the air data computer obtains flight parameters of UAV and communicates with central unit of avionics system of UAV. The analog signals from sensors conversion to digital and they process by microcontroller ADuC812. The algorithms of evaluation of flight parameters take into consideration the International Standard Atmosphere.
