Students are given a work assignment and topics related to the development of aircraft units and mechanisms. The study project consists of the calculation part, the design part and the drawing design part. The calculation part includes the kinematic calculation of the drive, as well as the calculation of the geometrical dimensions and strength of the drive components. The design part includes the design of 3D models of one of the drive unit elements in a computer program, as well as the creation of a 3D model of the assembly of unit elements and components. In the part of drawing design, students create the basic element and also the drawings of the assembly work.
