Abstract
The invention relates to the field of aeronautical propulsion, and more particularly an on-board drainage reservoir of an aircraft engine, the on-board reservoir including a first compartment with a first intake passage for receiving fluid drained from the engine, a first closeable emptying passage, and a first quality sensor assembly for detecting at least one quality parameter of the fluid drained from the engine.
Claims9
An on-board drainage reservoir of an aircraft engine, the on-board reservoir including a first compartment comprising:
- a first intake passage for receiving fluid drained from the engine,
- a first closeable emptying passage, and
- a first quality sensor assembly, within the first compartment of the on-board reservoir, for detecting at least one quality parameter of the fluid drained from the engine to the first compartment of the on-board reservoir;
- the on-board reservoir further including at least one second compartment with:
- a second intake passage for receiving fluid drained from the engine,
- a second closeable emptying passage, and
- a second quality sensor assembly, within the second compartment of the on-board reservoir, for detecting at least one quality parameter of the fluid drained from the engine to the second compartment of the on-board reservoir;
- and
- the on-board reservoir further including an additional compartment connected, downstream of the first and second compartments, to the first and second closeable emptying passages.
A method for monitoring a fluid of an aircraft engine, including the following steps:
- draining the fluid from the engine, to a first compartment of an on-board reservoir, by means of at least one first intake passage,
- detecting, by means of a first quality sensor assembly within the first compartment of the on-board reservoir, at least one quality parameter of the fluid drained to the first compartment of the on-board reservoir,
- draining the fluid from the engine, to a second compartment of an on-board reservoir, by means of at least one second intake passage,
- detecting, by means of a second quality sensor assembly within the second compartment of the on-board reservoir, at least one quality parameter of the fluid drained to the second compartment of the on-board reservoir, and
- emptying the first compartment of the on-board reservoir to an additional compartment by means of a first closeable emptying passage connecting to the additional compartment downstream of the first compartment, and
- emptying the second compartment of the on-board reservoir to the additional compartment by means of a second closeable emptying passage connecting to the additional compartment downstream of the second compartment.
