Abstract
The invention relates to an assembly (10) for a turbomachine comprising a pipe (12) connected at one end (12a) to means (14) for supplying pressurized air and at one opposite end (12b) to an item of equipment (16) of the turbomachine, the pipe (12) having a bent portion (12c) intended for forming in use a low point of the pipe (12), said bent portion (12c) having a hole (18) for first draining water from the pipe (12), wherein it further comprises an orifice (20) arranged downstream of the drain hole (18).
Claims15
An assembly for a turbomachine comprising a pipe connected at an upstream end to means for supplying pressurized hot air and at an opposite downstream end to an item of equipment of the turbomachine, the pipe comprising:
- a V-shaped bent portion for forming a low point lower than the upstream end and the downstream end of the pipe such that a drain portion of the pipe is inclined upwards downstream of the V-shaped bent portion;
- a drain hole in the V-shaped bent portion for draining water from the pipe;
- an outlet orifice for hot air arranged downstream of the drain hole and arranged upstream of the item of equipment, said outlet orifice opening to the outside of the pipe, wherein said outlet orifice opens upwards along an inclined direction, so that hot air flows upwards through both said drain portion of the pipe and the outlet orifice.
An assembly for a turbomachine comprising a pipe connected at one end to means for supplying pressurized hot air and at one opposite end to an item of equipment of the turbomachine, the pipe comprising:
- a V-shaped bent portion forming a low point lower than the upstream end and the downstream end of the pipe such that a drain portion of the pipe is inclined upwards downstream of the V-shaped bent portion;
- a drain hole in the V-shaped bent portion for draining water from the pipe;
- an outlet orifice for hot air arranged downstream of the drain hole and arranged upstream of the item of equipment, said outlet orifice opening to the outside of the pipe, wherein said outlet orifice opens upwards along an inclined axis, and the pipe is globally V-shaped, so that the pipe has:
- a first portion upstream of the drain hole and inclined towards said V-shaped bent portion, and,
- a second portion downstream of the drain hole and inclined towards said V-shaped bent portion, so that hot air can flow upwards along both the second portion and the outlet orifice for being inclined in the same direction as the inclined axis.
