| In the flight tests of an aircraft performance and quality, obtaining accurate data of control force, control displacement and
corresponding surface deflection is a powerful guarantee for studying maneuverability and stability. Aiming at problem that the traditional
calibration method cannot accurately reflect relation of the three kinds of control parameters, this paper carries out the research on the
joint online calibration technologies for the control parameters’ testing system. Through building wireless-sensor calibration network,
designing onsite calibration device, developing calibration software platform, the joint online calibration of multi-parameters was realized.
Onboard test results show that the proposed method leads to more than 50% increasement in calibration accuracy and about 67%
reduction in calibration time, and the displacement-force curve obtained from calibration is completely consistent with the design curve,
which verifies the feasibility and effectiveness of the joint online calibration system. |
