Title:
FORECASTING MAINTENANCE OPERATIONS TO BE APPLIED TO AN ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/086957
Kind Code:
A3
Abstract:
The invention concerns a method and system for forecasting maintenance operations to be applied to an aircraft engine comprising a plurality of elements monitored by damage counters, each damage counter being limited by a corresponding damage ceiling, characterised in that it comprises: - processing means (7) suitable for simulating a consumption of said damage counters (C1-Cm) by iteratively pulling a series of simulation missions from a learning database (9) containing test missions, - processing means (7) suitable for determining, at each iteration, an accumulation of consumption of each of said damage counters until at least one counter counting damage related to a current simulation mission reaches the damage ceiling associated with same, - processing means (7) suitable for applying a maintenance strategy to said current simulation mission to determine maintenance indicators representative of the maintenance operations to be planned on the aircraft engine.
