Description

Technical Field

[0001] This invention relates to the field of aircraft support equipment, and in particular to a method for confirming aircraft support equipment requirements. Background Technology

[0002] Aircraft support equipment, as a crucial component of aircraft equipment, is becoming increasingly important. The appropriate support equipment significantly impacts the scale of aircraft transfer and the effectiveness of support operations. Inadequate support equipment directly affects the scale of aircraft transfer resources, increases aircraft usage and maintenance time, reduces aircraft mobility and ferry efficiency, diminishes the aircraft's agile support capabilities, and further impacts combat effectiveness. Furthermore, the additional support equipment increases the user's procurement costs and leads to resource waste.

[0003] In the current field of aircraft support equipment requirements analysis, civil aircraft mainly refer to the European S3000L standard for supportability analysis, and obtain support equipment requirements based on MTA results; aircraft mainly follow the "Equipment Supportability Analysis" (GJB1371) and "Support Equipment Planning and Development Requirements" (GJB5967) for support equipment requirements analysis. Regardless of whether it is a military or civil aircraft, the technical characteristic is that the maintenance items are identified using the supportability analysis process, and then the aircraft designers propose equipment requirements for the maintenance items based on experience. After comprehensive optimization, the support equipment is matched.

[0004] From a technical perspective, the timing of the development of demand analysis methods for civil aircraft support equipment is relatively late, and there are many similar models that can be referenced, making it impossible to directly apply them to the demand analysis of aircraft support equipment. Due to the limitations of aircraft designers' experience, they often do not have a comprehensive understanding of the rationality of use and maintenance work items, the supporting equipment of other aircraft, and the technical specifications of support equipment. This results in poor matching between the analysis results and actual needs, which in turn affects the matching of aircraft support equipment and the user experience.

[0005] During the development of a certain type of aircraft, the current domestic methods for analyzing and matching support equipment requirements were adopted. This resulted in the utilization rate of the supporting equipment being less than 80%. During the user's trial period, repeated requests for adjustments to the supporting equipment were made. Ultimately, this led to continuous adjustments and changes to the supporting equipment, limiting aircraft maintenance and support capabilities.

[0006] How to standardize the review of aircraft support equipment requirements has become a technical problem that needs to be solved. Summary of the Invention

[0007] To address the aforementioned problems, this application provides a method for confirming aircraft support equipment requirements, characterized by comprising:

[0008] Step A: Obtain the initial requirements for aircraft support equipment;

[0009] Step B: Determine whether the usage or maintenance work items in the initial requirements are necessary. If they are determined to be unnecessary, cancel the corresponding support equipment requirement item; if they are determined to be necessary, proceed to the next step.

[0010] Step C: Determine whether the aircraft can self-sufficient through its own functions. If it can, optimize the aircraft's functions and eliminate the corresponding external support equipment requirements; if it cannot, proceed to the next step.

[0011] Step D: Compare whether similar aircraft are equipped with similar support equipment. If the result is no, explain the reason for the difference. If the result is yes, proceed to the next step.

[0012] Step E: Determine whether the support interface set up by the aircraft for the support equipment is compatible. If it is determined that it is not compatible, optimize the support interface of the aircraft until it is compatible, and then proceed to the next step.

[0013] Step F: Determine whether the technical specifications of the support equipment meet the aircraft requirements. If it does, re-evaluate the technical specifications and return to Step E for re-evaluation. If it is determined to be reasonable and feasible, proceed to the next step.

[0014] Step G: Determine whether the support equipment can be used with other models. If it is determined that it can be used with other models, then it is determined to be a general support equipment; if it is determined that it cannot be used with other models, then it is determined to be a special support equipment.

[0015] Preferably, after step G, the method further includes:

[0016] Step H: Summarize all the support equipment requirements confirmed through the aforementioned hierarchical decision-making process to form a support equipment requirement list.

[0017] Preferably, the comparison of similar aircraft in step D is based on a pre-generated multi-aircraft generalized support equipment analysis model or model library, which at least contains the support equipment names, functions, performance and interface information of different aircraft models.

[0018] Preferably, the basis for determining whether it can be used with other models in step G comes from the comparison results based on the analysis model or model library in step D.

[0019] Preferably, the initial requirements obtained in step A exist in the form of a requirements table, and the table elements include, but are not limited to: serial number, usage and maintenance work items, work timing, name of required equipment, protection object or purpose, main technical indicators and protection interface.

[0020] Preferably, the criteria for determining whether the use or maintenance work item is necessary in step B include:

[0021] Is this work item a mandatory item stipulated by the aircraft design specifications or airworthiness requirements?

[0022] Does this work project affect the aircraft's flight safety or airworthiness?

[0023] Is this work item a necessary part of routine maintenance?

[0024] Preferably, the criteria for determining whether the aircraft can achieve self-sufficiency in step C include:

[0025] Does the aircraft possess the sensors, actuators, or control units required to complete the task?

[0026] Whether the aircraft can achieve this function through software upgrades or parameter adjustments;

[0027] Does this work project fall within the scope of basic aircraft functions?

[0028] Preferably, the criteria for determining whether the support equipment can be used with other models in step G include:

[0029] Does the equipment's functionality and performance meet the requirements of multiple machine types?

[0030] Does the interface of this protection device have compatibility with multiple machine types?

[0031] Are the technical parameters of the support equipment within the scope of standardization?

[0032] The advantages of this invention are: it solves the problem of confirming aircraft support equipment requirements. The proposed requirement confirmation method enables the reasonable confirmation of initial requirements for support equipment, establishes a support equipment type library, and can guide the confirmation of aircraft support equipment requirements, effectively improving the rationality of aircraft support equipment requirements.
