Abstract

The CEA (for Aeronautical Studies Center in Spanish) of the Colombian Civil Aviation Authority (Aerocivil) has a subsonic wind tunnel called ELD 402B Eiffel for the development of aerodynamic practices. This allows to the Aeronautical Research Group to have a tool to carry out research and teaching tasks. The goal of the project presented in this paper was to develop an aerodynamic data acquisition system and the interfaces for the user. In order to improve the capabilities of this wind tunnel, it was developed and implemented a system that allows to acquire the voltage signals of the aerodynamic balance sensors, located in the test section. The acquisition and processing was carried out with the LabVIEW software tool, used to implement a graphic interface to visualize the variables delivered from the sensors. The variables tested with this tool are lift and drag coefficients, aerodynamic forces, and relative air speed in real time. This paper presents the results of the performance tests, the system design and the implementation process.
