Optimisation of the Composite Sensorcraft Structure for Gust Alleviation
نویسندگان
چکیده
Despite the benefits of composite structures, it is only recently that the main load bearing structures in large aircraft such as the Boeing 787 and Airbus A350 have started to be manufactured using carbon fibre composites. Even then, the unique directionality properties of composite laminates have yet to be exploited to improve the aircraft performance. In this study an aluminium and composite finite element model of the sensorcraft aircraft is developed in order to assess the ability of tailoring the composite structure to provide passive gust alleviation. Conclusions are drawn based on the amount of gust loads reduction that can be achieved using aeroelastic tailoring whilst taking into account a number of aeroelastic and structural constraints.

Imomlbressibte Flow Summary.-The report presents the theoretical calculations of gust alleviation factor made for rigid aircraft and with one degree of freedom only (i.e., vertical motion). It is shown that for average gust lengths and for orthodox (tailed) aircraft the influence of thesecond degree of freedom (i.e., pitching) on the value of the gust alleviation factor is negligibly small, pro...
متن کاملGust Load Alleviation Based on Model Predictive Control
Weight reduction is a typical design goal for modern aircraft. If gust encounters (as required by Certification Specification 25) are sizing conditions of parts of the airframe, this can be achieved (for example) by an active gust load alleviation system that reduces the gust load level down to the level of the next design condition, which might be the design loads from maneuver conditions. In ...
