The problem of assessing the sustainability of the family of unmanned aerial vehicles that are created on the basis of the basic model and have different weight, size and aerodynamic characteristics associated with the peculiarities of their application is examined. The method for assessing robust stability, based on research of Hurwitz interval characteristic equation of closed system is given. This method allows to obtain the stability areas for the combination of changes of output characteristics of interval data for parameters of the mathematical model, that enables to evaluate the robust properties of unmanned aerial vehicle design at the design phase.

 

Key words: aircraft, robust stability, interval parameters, the characteristic equation, the stability areas.
