Stability of optimal solutions in the formation of the operation process of small gas-turbine engines for a multipurpose helicopter

for helicopters (SGTE) and with the choice of values for the parameters of the operation process of SGTE. A considerable amount of uncertainty in the initial data may in the long run affect the SGTE efficiency and the deadline for the engine final improvement. Therefore methods for the finding of such values for the operation process parameters that would be resistant to the uncertainty of the initial data are considered in this paper. Given as an example are the results of calculations of the formation of a stability domain of the compromising design options of the helicopters SGTE.
