SEGMENT JOINT TO ENSURE TIGHTNESS IN AIR BLEED INTO AIRCRAFT CABIN

摘要

FIELD: mechanics.;SUBSTANCE: proposed invention covers, on the one side, compressor shell and circular structure jointed to the said shell and, on the other side, diffuser grid outer casing, bearing system jointed to aforesaid casing and engine casing outer shell. Note that the casing outside shell is fastened on the said circular structure by bolting flanges together and using appropriate sealing appliances arranged between the said circular structure and diffuser grid outer casing. Aforesaid sealing appliances comprise split annular segment with its radial part is set tight to allow sliding radially in groove arranged in peripheral zone of the said diffuser grid outer casing part, first upstream. Note that the said peripheral zone rests upon cylindrical sleeve inner surface, the sleeve being rigidly jointed to circular structure and enveloping the aforesaid segment.;EFFECT: tightness between space of air intake from engine and channel of primary gas flow passage in compressor under whatever operating conditions.;7 cl, 6 dwg
