DEVICE FOR PROVIDING CLEANLINESS OF PAYLOAD UNDER ASSEMBLY-PROTECTION UNIT OF SPACE-MISSION MISSILE Russian patent published in 2015 - IPC B64G1/46 B64G1/50 B64G5/00 

FIELD: transport.

SUBSTANCE: invention relates to environment parameter control in rocket-and-space engineering products during their preparation on launch installation and in flight. The device includes installed on adapter module (4) payload fairing (PLF) (3) of payload (PL) (1) brought out by space-mission missile (2). In the top part of PLF (3), splitter (5) of gas flow supplied via transit line (6) is installed. In the bottom part of PLF (3) the hatch (7) for gas component discharge is made. On the inner surface of PLF (3), noise, moisture and metal antistatic protective coatings are installed. In the hatch cover (7), a hole is made, and on the inner side of the cover, flat lattice acoustic muffler is installed. From the other side of cover (7) hole, local fairing is mounted (in the form of subsonic diffuser). On the adapter module (AM) (4), additional hole with filter (screen) and with similar local fairing is made (pos. D). Cavities of AM (4) and PLF (3) are communicated by holes (pos. E) made in ring of AM and by holes (22) in adapter (21). During liftoff and flight of missile (2) with PL (1) the level of acoustical action on them is lowered due to use of the mentioned protective coating, muffler and local fairings. Thus possibility of contaminants formation and entering into PLF cavities and hitting PL surface (in dead zones) is lowered.

EFFECT: high quality of cleanliness of PLF intracavity where PL is accommodated.
