The presented report examines the isolated longitudinal movement of a mini unmanned air vechicle type flying wing. The overall dimensions and the mass characteristics are taked from the developed MUAV. These features are introduced into the software environment of the virtual aerodynamic tunnel. The resulting mathematical model is statically balanced in the isolated longitudinal movement and the openloop system has been stability examined. The received state matrix is introduced into the state space model of the isolation longitudinal movement and the system is tested for stability and controlability. A matrix of the compensator is synthesized, and its optimal coefficients are found by two methods.

This report discusses the using of a free software to determine the aerodynamic coefficients of a developed MAV. The coefficients obtained, as well as the aerodynamic forces and moments, have been investigated for their applicability in the balancing and static stability of this type of aircraft. The results of the work are used to synthesize a suitable autopilot.

The present paper examines the use of free software to determine the aerodynamic coefficients of the selected MAVs. The resulting ratios and aerodynamic forces and momentums are tested for their applicability in the controlling of this type of aircrafts.

This paper presents the process of developing and studying of a complete mathematical model of the spatial movement of drones. The model synthesized is used in their automatic control systems.

Behavior of a specific constructive scheme of a tricopter is modeled. On the base of real characteristics of propeller-motor system, a model of the motion of the yaw mechanism is worked out. A flight stabilization method is proposed.
