METHOD OF MINIMISING ESTRANGEMENT ZONE FOR MULTISTAGE CARRIER ROCKET JETTISONABLE PARTS Russian patent published in 2012 - IPC F42B15/36 B64G1/64 

FIELD: process engineering.

SUBSTANCE: proposed method consists in computing rocket jettisonable parts flight parameters before parts fall on earth during preflight action to define required estrangement zone from computed parameters. Elements differing in degree of collapse in dense atmosphere after detachment from carrier rocket are isolated in jettisonable parts. For these separate detachable elements, required estrangement zone are computed. After separation of jettisonable parts and during their independent flight till entry to dense atmosphere, generated is the signal to separation actuators to make then separate into aforesaid isolated elements.

EFFECT: decreased are of estrangement zones.
