JACKET OF TURBOJET ENGINE WITH MULTILAYER PANELS AND DRAINAGE SYSTEM Russian patent published in 2020 - IPC F02C7/24 F02C7/45 F01D25/32 

FIELD: machine building.

SUBSTANCE: technical solution area: envelope of turbojet two-circuit engine with multilayer panels and drainage system. Application field: invention relates to aircraft and aircraft engine building, namely, to structures of shells with detachable acoustic panels and a drainage system, which ensures the passage of moisture condensate (rainwater) by gravity outside the shell. Turbojet double-track engine shell comprises multilayer panels which are acoustic and made detachable. Condensate of moisture (rainwater), removed from multilayer acoustic panels through drain holes made in side walls of soundproof enclosure, enters V-shaped gaps formed by side walls of adjacent panels. Further, through a system of longitudinal and transverse channels formed by ring surfaces, multilayer panels, as well as annular projections made by straps fixed on inner surface of ring, gravity flows into lower part of turbojet shell and through drain hole made in lower part of ring, is removed beyond its limits.

EFFECT: technical result is providing removal of moisture condensate (rainwater) outside the shell by gravity without additional devices.
