Turbofan jet engine with ancillaries distribution support
View Patent ↗A turbofan jet engine includes an outer casing supported by arms, an inner casing facing the outer casing, ancillaries, and an ancillaries distribution support. The ancillaries distribution support is formed along the axis of an arm on the inner casing. The ancillaries distribution support includes a first sole plate for reception of ancillaries on the outer side of the inner casing and a second sole plate for reception of ancillaries on the inner side of the inner casing. Such a turbofan jet engine reduces the longitudinal dimension necessary for the ancillaries to pass through.
1. A turbofan jet engine, comprising:
an outer casing supported by arms and including a recess therein;
an ancillaries passage assembly positioned in the recess of the outer casing;
an inner casing facing the outer casing;
ancillaries that pass through the ancillaries passage assembly; and
an ancillaries distribution support formed along an axis of one of the arms and positioned on the inner casing, comprising:
a first sole plate including a first set of ancillaries reception ducts to receive the ancillaries therein, wherein the first sole plate is positioned on an outer side of the inner casing, and
a second sole plate including a second set of ancillaries reception ducts to receive the ancillaries therein, wherein the second sole plate is positioned on an inner side of the inner casing.
2. The turbofan jet engine according to claim 1 , wherein the second set of ancillaries reception ducts include ancillaries fittings.
3. The turbofan jet engine according to claim 1 , wherein
the ancillaries passage assembly comprises an attachment flange, supporting a seal, and a seal support,
the seal is positioned in the recess of the of the outer casing and surrounded on three sides by the attachment flange, wherein the attachment flange does not surround a fourth side of the seal, and
the seal support is attached to the attachment flange such that the seal support surrounds the seal on the fourth side to fix the seal within the attachment.
4. The turbofan jet according to claim 3 , wherein the seal comprises ancillaries passage ducts that receive the ancillaries therein.
5. The turbofan jet engine according to claim 4 , wherein the seal is made of an elastomer material.
6. The turbofan jet engine according to claim 1 , further comprising:
an ancillaries protection arm installed between the ancillaries passage assembly and the ancillaries distribution support.
7. The turbofan jet engine according to claim 1 , wherein the outer casing is an outer ring of an intermediate casing and the inner casing is an inner ring of the intermediate casing.
8. The turbofan jet engine according to claim 1 , wherein the ancillaries are fixed to the first set of ancillaries reception ducts without using nuts.
9. The turbofan jet according to claim 3 , wherein
the outer casing includes a first gutter along a circumference of an output edge of the outer casing, and
the seal support is positioned in the recess of the outer casing and includes a second gutter that is continuous with the first gutter.
10. The turbofan jet engine according to claim 1 , wherein the first sole plate has a rounded triangular shape.
11. The turbofan jet engine according to claim 1 , wherein
each of the ancillaries includes a seal having an annular groove on a first end of the ancillaries,
the first sole plate includes a plurality of metallic plates including recesses, and
the annular groove of the seal of each of the ancillaries fits within one of the recesses of the metallic plates to block each of the ancillaries in translation.
