摘 要：In this paper we discussed the development of a morphing wingtip device or winglet for *** aim of this research is enhancing the aerodynamic of aircrafts,by optimizing the winglet shape,angle and torsion,to reduce wingtip vortices at each flight stage,reduce drag,fuel consumption and increase its *** development of a working physical wingtip device with morphing functionality,is possible by using piezoelectric MFCs(Macro Fiber Composites)as actuators in wing *** to their excellent properties like flexibility,light weight,tolerant to damage and long term stability MFC fit most of the requirements and specifications of morphing ***,they are based on the toxic compound of PbZrxTi1-xO3(PZT).Lead-free materials can replace lead based ***,other aim of this inquiry is the development of piezoelectric lead-free compounds based on the solid solution Ba1-xCaxTi0.9Zr0.1O3(BCZT)with x=0.1,0.125,*** reason for choosing these compositions is because BZCT compounds could reach a piezoelectricity coefficient d33~400 pC/*** value is comparable with commercial PZT,therefore it is a great candidate to replace it.
