METHOD FOR DETECTING A FLUID LEAK IN A TURBOMACHINE AND SYSTEM FOR DISTRIBUTING A FLUID

摘要

The invention relates to a method for detecting a fluid leak in a turbomachine. The turbomachine comprises a high temperature fluid source, at least one fluid distribution pipe adapted to distribute said fluid to different parts of the turbomachine and/or the aircraft which is intended to be equipped with said turbomachine, a turbomachine compartment in which the distribution pipe is at least partly accommodated, said compartment having in operation a low temperature relative to the high temperature of the fluid supplied by the fluid source. The method comprises the following steps: measuring a temperature variation in the compartment between two instants to obtain a temperature gradient; and detecting a fluid leak if the temperature gradient is greater than or equal to a threshold temperature gradient. The invention further relates to a system for distributing a high temperature fluid for a turbomachine and a turbomachine comprising such a system for distributing a fluid.

1. A method for detecting a fluid leak in an aircraft turbomachine, the turbomachine comprising:
a high temperature gas fluid source which provides high temperature gas fluid, at least one gas fluid distribution pipe adapted to distribute the gas fluid to different parts of the turbomachine and/or a aircraft which is intended to be equipped with the turbomachine, a turbomachine compartment in which the distribution pipe is at least partly accommodated, the compartment containing air which has in operation a temperature and a pressure respectively lower to the temperature and the pressure of the gas fluid, the method comprising the following steps: measuring a temperature variation of the air in at least one location in the compartment between two instants to obtain a temperature gradient, detecting a gas fluid leak in the compartment if the temperature gradient is greater than or equal to a threshold temperature gradient.
