Calculation and Experimental Method for Assessment the Basic Data of Aircraft Gas Turbine Engines for Military Purposes (p. 21 – 27)

B.P. Koren

The state of the issue of deterioration obtained in the process of testing, the values of the main parameters of aircraft gas turbine engines due to wear of their parts and components as the resource is developed. A computational and experimental method for determining the degree of deterioration of the values of the main parameters is presented and a new order of work is proposed to take this phenomenon into account at the stages of engine development and operation.

Keywords: testing of aircraft gas turbine engines; thrust; specific fuel consumption; deterioration of basic data; method of evaluation of basic data; mathematical model.

Development and Diversification of the Subsonic Airplane’s Technologies of the Integrated Scheme with the Triangular Wing. Part 2
(p. 28 – 39)

A.V. Bondarev, S.S. Vasin, V.G. Kagan, S.A. Kuzin, V.F. Samokhin, E.B. Skvortsov, O.V. Sonin, M.N. Chanov

The conception of the multipurpose subsonic airplane of the integrated scheme with the triangular wing proved the best solution of a number of modern tasks. Technologies which lie in a basis of this conception allow to expand a range of functional features, such as increasing of subsonic flight speed, reducing of influence on environment etc. The developed technologies allow to reach fundamentally higher level of consumer properties in civil airplanes projects of the future. The following publication is an extension to the article in a previous edition.

Keywords: diversification of technologies; integrated scheme; triangular wing.
