Abstract

A flight-experiment system including the test-bed vehicle, the ground station, and the catapult has been developed at Kyushu University, the purpose of which is to estimate aerodynamic characteristics of airplanes from flight data. Most of the sensors onboard are inexpensive and off-the-shelf ones in order to maintain the cost as low as possible, while the outputs of the sensors are carefully calibrated to assure data acquisition with high accuracy. The strong correlation among the variables which describes the change in a dependent aerodynamic variable is known as multicolinearity in regression analysis, which degrades the estimation accuracy. It is shown that this multicolinearity, which usually occurs among longitudinal variables due to elevator deflection is avoidable using an additional tail surface named a Flying Sting Balance.
