To the Question of Accounting for the Risks of Achieving the Assigned Aircraft Performance
(p. 28 – 32)

V.A. Klyagin, D.A. Laushin

When developing a new aircraft, technical decisions are made in the condition of inadequate information on the mass – size, aerodynamic characteristics of the aircraft and the engine altitude-airspeed performance that will be achieved in the process of the project. The article describes an approach that allows to reduce the risk of failure to meet the requirements of the tactical and technical assignment in conditions of uncertainties at the conceptual stage of design.

Keywords: uncertainties; risks; flight performance; preliminary design of the aircraft.

Design and Analysis of the Tether-Assisted Schemes for Returning Payloads from LEO (p. 33 – 40)

Z. Dong, Yu.M. Zabolotnov, C.Q. Wang

The multiple tether-assisted schemes for returning payloads from LEO are designed and analyzed in this paper. The feature of this work is that the aerodynamic forces acting on all parts of the system including on the tether are considered. In addition, the proposed schemes for returning payloads include the use of the atmospheric probe as an additional braking device.

Keywords: space tether system; payload; returning schemes; atmospheric probe; reentry angle.

Principles of Construction and Control of the Target Operation of a Cluster of Small Observation Satellites with a Distributed Optical Aperture (p. 45 – 54)

V.Yu. Klyushnikov

The article deals with the task of autonomous control of a promising self-organizing cluster of small Earth remote sensing satellites with a distributed optical aperture. Adaptive cluster self-organization is achieved through the use of multi-agent technologies (swarm control technologies).

Keywords: small satellite; formation flying; cluster; multi-agent technologies; swarm contro.

(c. 55 – 62)

E.G. Alekhin, A.A. Belkin, D.B. Danilov, V.A. Morozov, I.E. Fedorov

Describes a method for determining the volume of propellant components spent during the operation of the low-thrust engines in the event of complex bum-though tests for propulsion units with a pressurized fuel feed based on the actual consumed volume of the pressurizing gas.

Keywords: complex bum-through tests; low-trust liquid propellant rocket engine; rocket fuel components; rocket technology; spherical supercharger tank; gas-dynamics evaluation.
