Statistical estimation of Resurs-DK1 SC image quality modified to acceptable survey conditions
1 1., 1 1., 1 1., 1 1.
Abstract

Instrumental assessment results of linear ground resolution of images, acquired during normal operation of RESURS-DK1 SC were statistically handled by modifying them to acceptable survey conditions. Conclusion about fulfilling the SC performance task requirements, particularly requirements to linear ground resolution within panchromatic spectrum range, was proved on the basis of voluminous statistical data (more than 900 scannings). Exponential function was chosen as approximating expression of linear ground resolution. Appreciable best image plane travels were detected during normal SC operation.

Abstract

Using the scheme of radiant heat transfer between the unbounded plane and rows of tubes in parallel planes, considered heat transfer inkjet linen cloths coolant moving in the longitudinal direction of die refrigerator drip emitters and ending in space. A design scheme of temperature changes during cooling jet linen cloths in space. We calculated the formula for determining the current and the average temperature along the length of linen cloths, as well as the length of linen cloths depending on the heat load from the Erase spacecraft. Using the proposed simple model of heat transfer inkjet linen cloths refrigerator drip emitters and space led to the practical coincidence of our calculations the number of drop of heat into outer space droplets refrigerator and the average temperature along the length of the jet with the results obtained using a complex model of heat transfer drop linen cloths Konyukhov G.V.

Experimental determination of acoustic loads daunches of Strela LV and calculation of test modes for a spacecraft to be delivered by it to space
1 1., 1 1., 1 1., 1 1.
Abstract

During operation of Strela LV the levels of acoustic loads, affecting the LV head section and payload accommodated inside, have been experimentally determined when launching LV out of the  silo and  in the phase of maximum dynamic pressure,.

The results of acoustic loads measurements were used for generation and verification of Strela LV head sections models.

These models became the basis of procedure for calculation of the acoustic field affecting a spacecraft accommodated under the LV fairing.

The report studies the problems of simulating the spacecraft structure reaction to acoustic loads.

Comparative analysis has been carried out for the spacecraft reaction to acoustic and vibration loads at the levels corresponding to «Strela LV user manual». Based upon the results of comparative analysis the conclusion was made that the spacecraft structure reaction to vibration loads prevails over its reaction to acoustic loads.

Abstract

Programming of control logic and algorithms for onboard control systems is analyzed in the article. Since the applicable software engineering methods haven’t met the modern CAD requirements in most cases, the authors discuss formalized input and output data representation as a way out for effective infotainment of programming. Efficient information support of control logic and algorithms programming makes it possible to reduce design time, use computer aids for documenting, displaying and storage of design documentation, that results in improvement of satellite performance.
