Forming of perspective requirements to the parametric look of power-plant of cargo airplane

V.V. Loginov, E.Y. Ilenko

In the article the approach to estimation of technical perfection of the developed engine of the vehicle power-plant is considered, based on application of method of gravimetric coefficients. A comparison of all indexes and characteristics is made on the basis of the use of index of technical perfection, which characterizes the developed standard in relation to existent analogues. Substantial advantage of the engine D-27 before other engines by many characteristics is shown, and also contributions of parameters to the index of technical perfection. The ways of further researches are definite.

Key words: power-plant, integration, gravimetric coefficient, index of technical perfection, method of comparison.
