Allocation of distributed flaps for gust load alleviation [PDF]
2017 IEEE Conference on Control Technology and Applications (CCTA), 2017 Increasing the number and functionality of control surfaces provides great potential to improve aircraft performance. This, however, complicates the design of the control allocation system commonly used for flight control. A novel method for linear control allocation is presented which allows considering an arbitrary number of frequency dependent ...

Gust Load Alleviation of Flexible Composite Wing
CFD Letters, 2020 Gust load due to atmospheric turbulence is mandatory to be considered in aircraft analysis as part of airworthiness requirement. This safety related issue becomes more relevant recently in relation to the global warming that induces more frequent and extreme atmospheric disturbances encountered during air transportation.
