Transport space system "Ryvok-2" for crew deliver to the lunar base (p. 3 – 9)
R.F. Murtazin
The concept of the russian lunar program considers the creation of a superheavy launch vehicle with a payload capacity of about 100 t, and in the future, with its help, the deployment of a lunar base. Using the ideas, presented in [1], space transportation system «Ryuvok -2» is proposed to deliver reusable lunar vehicle from the earth orbital station to the lunar base and back. The superheavy launch vehicle as the main means of insertion and the braking at the Earth after returning from the Moon is performed by applying a burn using propulsion system. For the considered variant, the mass of the refueled reusable lunar vehicle will be 7.5 t with a design mass including a crew of about 4.0 t.
Keywords: space transportation system; orbital station; lunar base; reusable crew vehicle.

The Diagnostic Information Control in the Gas-Turbine Engine Tests лей (p. 10 – 15)
G.P. Shibanov
Algorithms for detecting failures and distortions of diagnostic information used for monitoring the technical condition of gas turbine engines are proposed. Statistical features which allow to classify the controlled process as stationary or non-stationary one with a high degree of confidence, and based on this, choose the most rational control strategy are described.
Keywords: control; diagnostics information; tests; gas-turbine engine; statistical algorithms.

The Impact of Innovation on Firm Performance: a Study of Russian Defense Companies (p. 16 – 27)
A.V. Trachuk, N.V. Linder
The impact of innovation on the efficiency of the defense industry complex enterprises functioning is studied. The empirical analysis is based on data from the 97 defense enterprises (183 respondents) of the aviation, rocket and space, shipbuilding, radio and electronic industries, industries of conventional arms, munitions and special equipment industries. Factorial and regression analysis are used, allowing to estimate the dependence of various types of innovations on the efficiency of the enterprises activity. Within this research three resultant indicators of efficiency of defense industry enterprise activity are allocated: net profit, diversification and labor productivity level.
Keywords: innovations (grocery, technological, organizational, administrative); efficiency of defense industry enterprises; productivity.

Design Analysis of Lander’s Aerodynamic Forms for Landing on the Venus Surface
(p. 28 – 42)
A.V. Kosenkova, V.E. Minenko, A.G. Yakushev
Alternative to the traditionally used ballistic type of a lander variants of lander’s forms to the Venus surface are considered. A comparative analysis of these landers made by operational design evaluation of the aerodynamic forms of a lander is presented. Variant of aerodynamic form of a lander is proposed and justified for its future studying as a perspective lander for controlled descent and landing on the Venus surface.
Keywords: lander; aerodynamic form; aerodynamic characteristics; Venus; maneuverability; hypersonic velocity range.

UAV Navigation Complex using the Electronic Systems Division (p. 43 – 50)
N.S. Grigorenko, D.G. Pantenkov
The paper considers the example of UAVs, especially the "UAV Navigation Complex using the Electronic Systems Division is considered." One of the options and a different approach to the UAV navigation complex is proposed for use in the face of the uncertainty nature of errors of global navigation satellite system signals.
Keywords: unmanned aerial vehicle; electronic systems division; takeoff runaway; operator interface.

Method for Calculating Trajectories
of Motion of Small Particles in an Inhomogeneous Flow Field
(p. 51 – 56)
Yu.A. Nikitchenko, D.A. Kudryavtsev
The calculation methodology of flow field trajectory for new aircraft was proposed in this work. This method helps with estimation of particle orbits that was created by destruction of particular parts of the aircraft. Implementation procedure of this method was developed.
Keywords: flow field; particle orbit; statistical analysis.
