Embodiment Construction
[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0051] The specific implementation steps are as follows:
[0052] 1. Parameter initialization
[0053] a) Parameter initialization of flight test subjects
[0054] The number of initialization subjects N is 40, and the details of flight test subjects are shown in Table 1:
[0055] Table 1 Detailed information of flight test subjects
[0056]
[0057]
[0058] The pre-relationships between various flight test subjects are attached figure 1 As shown, the arrow in the figure points from the front subject to the post subject. According to the pre-relationship, subjects 1-30 are divided into 2 "branches", and there is no pre-relationship between the subjects of each "branch", and subjects 31-40 are "scattered subjects", that is, there are no pre-subjects and no post-subjects .

The invention provides a flight test task allocation optimization method for a civil transportation aircraft, which comprises the following steps: performing mutation operation and crossover operation on chromosomes through parameter initialization, coding and population initialization, judging whether the current chromosomes conform to logic constraints, and generating test flight subject arrangement results for the chromosomes conforming to the logic constraints; calculating and traversing all chromosomes in the population through an objective function value, and carrying out selection operation by adopting a binary tournament selection mode to obtain a new population until an optimal subject arrangement result is selected. According to the method, the flight test arrangement result meeting the test flight constraint condition can be automatically obtained according to the civil transportation aircraft flight test task information, and the subject sequence is optimized by adopting the genetic algorithm, so that the effect of shortening the test flight period is achieved.
Description
technical field [0001] The invention relates to the field of civil transport aircraft flight tests, in particular to a task allocation method. Background technique [0002] Civil transport aircraft need to conduct flight tests in accordance with the airworthiness requirements specified by the airworthiness authority to verify whether the design, manufacture and use of civil transport aircraft meet flight safety standards. Flight tests need to consider pre-factors such as test requirements, flight test conditions, and flight test safety to determine the order of flight test subjects and assign flight test tasks. The effect of flight test task allocation optimization directly affects the flight test cycle, thus determining whether the aircraft can be delivered on schedule. Therefore, the optimization method of flight test task allocation is a key problem to be solved in the field of civil transport aircraft flight test. [0003] The flight test task allocation optimization p...
