Problems solved by technology
Due to the inability to accurately predict the repair cycle of aero-engines, it poses great challenges to the preparation and delivery plans. Air operators are often forced to use temporary leases to support fleet operations. However, the high costs of temporary leases will affect aviation The operator's capital chain creates certain pressure

Embodiment Construction
[0129] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0130] Such as Figure 1 to Figure 2 As shown, according to an embodiment of the present invention, a method for predicting the maintenance time of an aero-engine in a repair shop is provided, the aero-engine includes a plurality of components, comprising the following steps:
[0131] Step 1: Classify the repair level of the aero-engine based on the scope of work of the aero-engine (the scope of work refers to the normative documents that stipulate the degree of disassembly and repair depth of each component of the engine), and classify the repair levels of the aero-engine into: deep overhaul of components, Performance restoration repairs and troubleshooting repairs;
[0132] Step 2: Divide t...

The invention provides a method for predicting the maintenance time of an aero-engine in a repair shop. The aero-engine includes a plurality of components. The method comprises the steps of classifying the levels of repair of the aero-engine based on the scope of work of the aero-engine; dividing the maintenance process of the aero-engine in the repair shop into three phases: a first phase of putting the aero-engine to a maintenance station position of the repair shop and conducting main inspection, a second phase of repairing and integrating the components of the aero-engine and a third phase of assembling the aero-engine and conducting a test run; and obtaining the time required for each of the first to third phases, adding the time required for each of the first to third phases, also taking the holiday and festival information into consideration, and finally obtaining the predicted maintenance time of the aero-engine in the repair shop.
Description
technical field [0001] The invention relates to the field of aero-engine repair process control and cycle prediction, in particular to a method for predicting the maintenance time of an aero-engine in a repair shop. Background technique [0002] Due to the technical limitations of the original aero-engine factory, the repair shop has no ability to repair some core components of the aero-engine, and needs to send them to the manufacturer designated by the original factory with maintenance qualifications for repair, making it difficult for the repair shop to effectively control the repair cycle of the delivered components . In addition, due to the high requirements for the manufacturing process of aero-engine components, there are few manufacturers worldwide that can supply new parts. When ordering new parts, repair shops often encounter long lead times or shortages. The inability to accurately predict the delivery cycle of repair parts and new parts makes it impossible for r...
