Use of composite materials to increase the effectiveness of variable-geometry aircraft

The results of mathematical modeling of the functioning of the charges using composite materials forming high-speed aircraft of variable geometry are presented. The directional formation of a folded fin in the tail part of the element, providing the aerodynamic stability of the element on the trajectory, is considered as a way to increase the efficiency. The effect of charge parameters on the effectiveness of the action is shown. At the same time, steel claddings of variable thickness and claddings of polymeric material for the formation of a folded fin were considered. The effectiveness of the charges was determined by the shape of the element and its speed. It is found that with an increase in the width of the petal cladding the speed of the element decreases, a linear relationship is presented between the relative width of the cladding and the relative speed. It is revealed that the elongation of the element when varying the width of the cladding varies nonlinearly and there is a range of sizes of the cladding at which the elongation is minimal.
