Abstract

Analysis of project development and space research using contact method, namely, by means of automatic descent modules and balloons shows that while designing formation of EDL sequence and operation in the atmosphere are of great importance. This process starts at the very beginning of designing, is undergone a lot of iterations and influences processing of normal operation results.
Along with designing of descent module systems, including systems of braking in the atmosphere, designing of flight operation sequence and trajectories of motion in the atmosphere is performed. Due to how philosophy of the entire operation sequence and transfer from one phase to another was correctly chosen the probability of experiment success on the whole and efficiency of application of various systems depend.
By now the most extensive experience of Russian specialists in research of terrestrial planets has been gained with the help of automatic interplanetary stations “Mars”, “Venera”, “Vega” which had descent modules and drifting in the atmosphere balloons. Particular interest and complicity of formation of EDL and drift sequence in the atmosphere of these planets arise from radically different operation conditions, in particular, strongly rarefied atmosphere of the one planet and extremely dense atmosphere of another. Consequently, this determines the choice of braking systems and their parameters and method of EDL consequence formation.
At the same time there are general fundamental methods and designed research techniques that allowed taking general technical approach to designing of EDL and drift sequence in the atmosphere.
