Embodiment Construction

[0033] The method and device for generating the reliability test profile of the aircraft provided by the present invention will be introduced below in conjunction with the accompanying drawings.

[0034] figure 1 The schematic flow chart of the generating method of the reliability test profile of the aircraft provided by the present invention, as figure 1 As shown, the generation method of the reliability test profile of the aircraft provided by the invention comprises:

[0035] S1. Determine the proportion of each mission profile of the aircraft, and the environmental profile category of the aircraft.

[0036] Exemplarily, determining the proportion of each mission profile of the aircraft may include:

[0037] Step 11. Determine all mission profiles of the aircraft according to the tasks performed by the aircraft.

[0038] For example, if the aircraft is a civil passenger aircraft, the tasks performed by the aircraft usually include: passenger flight profile and training f...

Abstract

The invention provides a method and a device for generating a reliability test profile of an aircraft. The method comprises the following steps: determining the proportion of each mission profile of the aircraft and the environmental profile category of the aircraft; determining environmental parameters of the aircraft, wherein the environmental parameters comprise at least one of temperature, humidity, vibration and electric stress; and according to the proportion of each mission profile of the aircraft and the environmental parameters of the aircraft, obtaining the value of each environmental parameter under each environmental profile category of the aircraft within the single cycle test duration range, and taking the value as a reliability test profile under each environmental profile category.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a design method and device for a reliability test profile of an aircraft. Background technique [0002] The test profiles of existing reliability tests are mostly designed according to the test profile recommended by GJB 899A, and it is relatively simple to select a large proportion of typical task profiles to design. [0003] It is applicable to turboprop aircraft with few mission profiles or those with similar mission profiles, but it is less useful for aircraft with many mission profiles and large differences between mission profiles. Contents of the invention [0004] The invention provides a method and device for designing reliability test profiles of an aircraft, which alleviates the problem that the existing method has poor reference for aircraft with many task profiles and large differences between the task profiles. [0005] The first aspect of the prese...
