Mathematical modeling of the turbopropfan engine when tested coaxial propfan with automatic control system on stand seminatural modeling

Abstract

 On the basis of the experience gained in the development of propellers, coaxial propfans and hydromechanical control system propose an approach to mathematical modeling turbopropfan engine when tested coaxial propfan with automatic control system on stand seminatural modeling. The proposed approach to modeling can adequately reproduce the transients of the propulsion plant on the stand seminatural modeling over the entire range of expected operating conditions.
