Abstract (en)
[origin: WO2022084604A1] The invention relates to an aircraft turbomachine module, comprising two tubular casings which are provided with first and second annular flanges joined together by lugs (24a, 24b) that are received in the first flange and that receive nuts at the back of the second flange, each lug comprising an intermediate section (34a, 34b) that is hexagonal in shape and cooperates with an attached plate (36) which comprises a first orifice (38, 38a) received on said intermediate section (34, 34a) by means of at least two opposing walls (58, 58a), this attached plate (36) comprising a transverse body (40) which is immobilized so as to prevent rotation of said plate (36) and of the lug (24, 24a, 24b), characterized in that each plate (36) is attached to two immediately adjacent lugs (24a, 24b), and in that the body (40) comprises, to that end and opposite the first orifice (38a), a second similar orifice (38b) that is received on an intermediate section (34b) of an immediately adjacent lug (24b), and cooperates with the hexagonal intermediate section (34b) of said lug (24b).
