The Siberian Legacy of Bartini (pp. 3 – 11)
A.N. Sereznov, V.L. Chemezov, V.A. Mymrin
The work of R.L. Bartini in the aerodynamics department of the Siberian Aviation Institute on the development of the concept of a distant strategic supersonic carrier is discribed. As well as the contribution of the SibNIA research team to the development of the aerodynamics of the vertically taking off amphibian VVA-14, the aircrafts of the non-contact take-off and landing of 14M1P and the ekranoplanes A-2000, T-500. Examples of the realization of the scientific and technical reserve acquired by the specialists of SibNIA consequently close interaction with R.L. Bartini in modern and prospective models of Russian aeronautical engineering are considered.
Keywords: 120 years since the birth of the chief designer R.L. Bartini; long-range supersonic carrier; vertical take-off amphibian; ekranoplane-aircraft-capable ship A-2000; the scientific and technical reserve of the R.L. Bartini.
Spacecraft Dynamic Model Identification Using Telemetry Data During Flight Tests (pp. 12 – 20)
P.P. Telepnev, V.V. Efanov, D.A. Kuznetsov
This paper describes developed and widely used in «Lavochkin Association», the technique of dynamic schemes parameters determination on the results telemetry data during flight testing of the spacecraft.
Keywords: dynamic model; identification; harmonic analysis, amplitude frequency characteristic; the coefficient of correlation.
Analytical Solutions of the Equations of Large Vortex Mechanics with Single-Stage Model of Free Boundary Layer (pp. 21 – 28)
A.G. Prudnikov, A.M. Podvalnyy
A constant-free solutions of the movement equations for one of the two half-waves traveling wave instability are presented. The surfaces of tangential discontinuity are analyzed for two slipstreams with different densities. The birth of a large vortex with constant vorticity is given for a vortex classical free boundary layer.
Keywords: free boundary layer; surface of tangential discontinuity; large vortex; movement equations; model with constant vorticity.
Mechanics of Destruction of the Descent Vehicle Upon Impact Against the Ground Surface (pp. 29 – 35)
V.I. Pogorelov, V.V. Ignatievв
The model of the descending capsule and the method for calculating the shock interaction of the descending capsule with ground was developed, materials of construction were chosen. The physico-mechanical properties of materials and soil were determined. The calculations for different rates of speed of the descent capsule were made. The maximum speed of the descent capsule at which the integrity of the payload is preserved was determined.
Keywords: mechanics of destruction; descent vehicle; impact; ground; method; descent capsule; payload; deformation; falling speed; designing; construction; landing.
Predictive Assessments of the Characteristics of Advanced Monitoring Spacecraft (pp. 36 – 44)
Hyunjai Cho, Yu.A. Matveev.
The models for determining mass and cost characteristics, main functional characteristics and reliability of perspective monitoring spacecraft are considers. Research about predictive assessments of characteristics of advanced spacecraft for monitoring the natural environment. The influence of the project implementation schedule on the characteristics of advanced spacecraft.
Keywords: observation satellite; the geostationary orbit; mass of sensor complements; project cost; project implementation schedule; influence of time; functional characteristics.
Accidence of F-16 Fighter/Bomber and its Options (pp. 45 – 51)
Multivariative technical-and-economic accidence analysis of F-16 and its options at the end of ten years time after the «cold war» (2001–2002) as the most popular foreign industry-standard fighter-bomber is given. It was demonstrated that the predominant accident cause factor was equipment.
Keywords: accident cause factors; mishap class; elevation of aircraft rescue.
