METHOD TO PROVIDE THERMAL CONDITIONS AND CLEANLINESS OF ENVIRONMENT FOR PAYLOAD UNDER ASSEMBLY-PROTECTION UNIT OF SPACE-MISSION MISSILE AND DEVICES FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2015 - IPC B64G1/46 B64G1/50 B64G5/00 

FIELD: transport.

SUBSTANCE: set of inventions relates to methods and means of environment parameter control in rocket-and-space engineering products, in particular during pre-launch preparation of modern carrier rockets (CR) for payload (PL). These CRs are equipped with systems for preconditioning and feeding thermostating gas component (GC) with high degree of purification over on-board gas lines of CR units. The method includes GC delivery and feeding to payload fairing (PLF) through upper and lower atomizers at the same time. Delivery is performed over single trunk gas passage in direction from bottom to top. Splitters of variable cross-section of the upper atomizer are placed mutually opposite so that when GC is blown jets could collide with each other over PL and be reflected by PLF thus equalizing field of GC speeds. This creates GC uniform flow in space between PL and PLF. In the lower cavity of PLF, GC is directed onto PL creating in PLF excess pressure due to which GC is discharged through special holes. In method implementing devices, atomizers are made as opposed splitters of variable cross-section which are blinded off on one end and combined by manifold of variable cross-section on the other end.

EFFECT: higher efficiency of thermal conditions and cleanliness of environment for PL installed on CR under PLF provisioning.
