METHOD OF MINIMIZING EXCLUSION ZONES FOR CARRIER ROCKET DETACHABLE PARTS Russian patent published in 2019 - IPC F42B15/36 B64G1/52 

FIELD: rocket equipment.

SUBSTANCE: invention relates to design and operation of carrier rockets and their detachable parts (DP): spent stages, transition compartments, fairing flaps, etc. Method includes a stage of preflight preparation of the carrier rocket, at which parameters of motion of DP are calculated, determining sections of lowering trajectory for impact on DP. Carbon-fiber reinforced plastic is fitted with a pyrotechnic composition which, when combusted, enables to heat the gas to combustion temperature in the oncoming air flow. At the design altitude, said composition is used, igniting the ignition composition, which is ignited by the DP. As a filler of the structure of DP, a dominant mixture of a power-consuming component with a synthetic polymer is used, which gives the maximum heat transfer to the DP. Gases released during combustion are directed into hollow channels of filler (made in the form of corrugated or rod structure). Energy-intensive component used is an oxidising agent (for example, ammonium perchlorate), and in pyrotechnic composition – for example, a mixture of powders of aluminum with iron oxide.

EFFECT: technical result is aimed at achieving completeness of DP burning in atmosphere and elimination of problem of alienated areas of DP fall.
