UPPER AXIAL RETENTION MEANS FOR THRUST REVERSER OF CASCADE TYPE WITH SLIDING BLADES OF D-SHAPED STRUCTURE Russian patent published in 2023 - IPC F02K1/56 F02K1/72 F02C7/20 

FIELD: aviation.

SUBSTANCE: invention relates to power plant (1) of an aircraft, containing turbojet engine (5) containing fan case (45), nacelle (3), and suspension pylon (15). In this case, the nacelle contains a rear along a flow section of D-shaped structure, accommodating a device of a thrust reverser and containing deflecting lattices made with the possibility of movement, wherein the specified rear along a flow section having D-shaped structure contains two D-shaped semi-structures having: an outer half-bonnet made with the possibility of progressive movement along the longitudinal axis; connecting means between deflecting lattices and the specified outer half-bonnet; a semi-branch “for 12 o’clock”; an inner semi-structure defining an inner part of an annular flow channel. At the same time, the specified nacelle contains a half-beam “for 12 o’clock”, installed at the semi-branch “for 12 o’clock”, pivotally fixed on the specified pylon; a means for axial retention for axial retention of the rear along a flow section of the nacelle relatively to the turbojet engine, made with the possibility of provision of connection defining axial retention between at least one of the specified half-beams “for 12 o’clock” and a stationary element of the fan case of the turbojet engine.

EFFECT: invention provides reduction in an axial gap between a fan case and a device of a thrust reverser.
