However, this implementation comes with a weight penalty due to the morphing mechanisms. In the present study two morphing winglet cases are tested, where due to mechanisms compatibilities, only a variable Cant-Span winglet and a variable Sweep-Span winglet are proposed. For these two cases, the cant angle mechanism presents a high actuator requirement of about 750 [kg], when restricted to a winglet AR of 3.16 and a minimum cant angle of 33 [deg]. For the morphing sweep case, the weight penalty is of less than 50 [kg]. As a result, during a mission analysis, the extra weight penalty for the first winglet case increments the MTOM of the aircraft in 2500 [kg], while for the second case, the MTOM is reduced by about 1000 [kg]. The consequence of this is a higher fuel consumption for the first case, but a lower fuel consumption for the second one, where a fuel reduction of a 2.2% is achieved. Another benefit is a lighter wing structure due to the load alleviation capabilities, and a higher range of almost a 9% for maximum fuel is obtained.
