Scientific and methodological approaches to minimizing the technogenic impact of launches of the promising launch vehicles of the Irtysh type with the oxygen-kerosene main liquid rocket engines of the Baiterek rocket complex in the impact areas of the Baikonur cosmodrome are considered. The basic directions for the reducing the technogenic impact of the worked-off booster of the first stage of the Irtysh type launch vehicle in the impact areas are: determining the optimal site for the worked-off stages (WS) fall in the selected zones of the impact areas that have the greatest resistance and the minimum cost on the restoration of the soil grounds of the site of the WS fall to its initial state - (A); controlled WS descent after separation from the LV into the designated site of the fall with an accuracy not exceeding the size of the selected optimal site - (B). To solve problems of the direction A, it is proposed to create an additional information and analytical system of the impact area. To solve problems of the direction B, possible design solutions are proposed based on the evaporation of unused liquid fuel residues in the WS tanks, and using the resulting vapor-gas mixtures for controlled WS descent to the dedicated zone of the impact area.

The unmanned mobile system of any transport facilities (land, space and underwater) should have high extent of reliability and non-failure operation in process. The elementary mechanical system in a combination to the elementary control system can provide these qualities. Besides the unmanned mobile system of space and underwater transport should have small sizes and weight and self-regulation possibility at origination of non-staff situations. Automatic gearboxes existing now (CVT) are the most complicated mechanical systems and have the most complicated hydro mechanical control system [1]. Such transmissions are absolutely unsuitable for unmanned mobile system because of their low reliability and inadequacy to a changing circumambient. Recently adaptive gear variators are developed [2, 3, 4, 5].  The adaptive variator represents the self-controlled gear planetary train with the constant engagement of the toothed wheels. Who’s that was created on the basis of an author's disclosure «Effect of force adaptation in mechanics». The adaptive gear box of the automobile represents a brand-new planetary gear variator in the form of two mobile kinematic chain with the elementary additional original constraints. The adaptive variator has ability to drive the executive tool with a speed which is back - proportional external loading at constant power of an engine. The basic advantages of an adaptive gear variator: absence of the control system, simplicity of a design,  full adequacy to working conditions. It seems expedient to use an adaptive gear variator in the transmission of a mobile transport system. Adaptive drivetrain based on usage of a gear variator (theoretical bases, tests, characteristics and practical recommendations) is in-process presented.
