Abstract

Wind disturbances especially vertical gusts and turbulence can deteriorate the quality of measurements performed by the payload of utility aircraft. Gust load alleviation systems can reduce this effect significantly if the atmospheric disturbances are determined precisely and broadband up to the frequency range of the short period mode. A novel approach to determine vertical gusts and turbulence that can be used for future implementation in a gust load alleviation system based on feed forward control is presented. This approach uses a linear aircraft model of the longitudinal aircraft motion combined with the Dryden Turbulence Model within a Kalman filter framework. For performance analysis it is compared to an algorithm using simplified flight mechanical relations. For proof of the concept and its robustness, different kinds of disturbances such as discrete gusts and a bias in the angle of attack measurement are simulated and discussed.
