The usefulness of factorial experiments and their advantage over the classical multifactorial experiments for testing ULPTs are justified. The choice of influencing factors of the planned experiment, i.e. regime and constructivegeometrical parameters significantly affect the efficiency, weight, size and technical-economic indicators is made for ULPTs of three types: axial, centrifugal and centripetal. Optimal rotatable orthogonal central composite designs of factorial experiments for testing different types of turbines and their basic parameters are formed.</p>Design of experimentsingle-stage ultralow power turbineinfluence factorsoperating conditionsstructural and geometric parametersperformance measuresПланирование экспериментаодноступенчатые турбины сверхмалой мощностивлияющие факторырежимные параметрыконструктивно-геометрические параметрыкритерии оценки эффективности
