Embodiment 1

[0022] On the basis of the maturity model, this embodiment proposes a modeling method of the flight test maturity model: figure 1 As shown, on the basis of the maturity model, the flight test maturity model is formed according to the different stages of aircraft test flight experience and weapon equipment development; There are six maturity levels set from low to high, including verification flight test level and acceptance flight test level, and each level of the six maturity levels evaluates the aircraft flight test work through the key state dimension, forming a step-by-step flight test maturity Improve the route.

[0023] The flight test maturity model FTMM (Flight Test Maturity Model) of this embodiment is a hierarchical description model, and is a method for structurally describing and measuring the maturity of the developed aircraft during the flight test process. The level FTML (Flight Test Maturity Level) in the flight test maturity model presents the characteristics...

Embodiment 2

[0037] A modeling method of a flight test maturity model: on the basis of the maturity model, a flight test maturity model is formed according to different stages of aircraft test flight experience and weaponry development; , adjust the flight test level, finalize the flight test level, verify the flight test level, and accept the flight test level to set six maturity levels from low to high, and each level of the six maturity levels evaluates the aircraft flight test work through the key state dimension , forming a step-by-step flight test mature improvement route. According to the elements and requirements involved in aircraft development and flight testing, the key status dimensions include technical status dimensions, manufacturing status dimensions, integration status dimensions, flight test status dimensions, and RMS status dimensions.

[0038] The flight test maturity model describes a way of continuous maturation of the aircraft equipment's technical state, manufacturi...

Embodiment 3

[0088] This embodiment further describes the flight test maturity model on the basis of embodiment 1 or embodiment 2, from image 3 It can be seen from the model frame structure diagram that the evaluation method of the flight test maturity model FTMM in this embodiment is to first divide multiple flight test maturity levels from low to high, and then evaluate the aircraft flight test work according to the standards of each level. Evaluation was carried out to form a step-by-step flight test mature improvement route.

[0090] Table 2

[0091] As shown in Table 2, the flight test maturity model introduces dimensions such as technology state, manufacturing state, integration state, flight test state, and RMS state, and refines the content of each dimension, making the description of flight test maturity more objective and comprehensive. Each maturity level is described along five dimensions. The five status descriptions have corresponding content at each level, thu...

Abstract

The invention discloses a modeling method of a trial flight maturity model. The trial flight maturity model is formed on the basis of a maturity model according to aircraft trial flight experience anddifferent stages of weapon equipment development; the trial flight maturity model is divided into six maturity levels including a non-trial flight level, a first flight level, an adjustment trial flight level, a setting trial flight level, a verification trial flight level and an acceptance trial flight level from low to high, and each level in the six maturity levels is used for evaluating the aircraft trial flight working condition through key state dimensions so as to form a step-type trial flight maturity improvement route. According to the method, the maturity model is introduced, relevant states and requirements of the aircraft trial flight are described in detail in stages and levels, a scientific method is provided for the level-transfer evaluation in the trial flight process, anda more powerful, more scientific and more systematic support is provided for improving the trial flight task completion efficiency and the trial flight safety control.

Description

technical field [0001] The invention belongs to the technical field of flight test modeling, and in particular relates to a modeling method of a flight test maturity model. Background technique [0002] From development to finalization, each newly developed model needs to go through multiple stages such as first flight, adjustment test flight, verification test flight, and finalization test flight. This process is gradually verified with the status, quality, function and performance of the aircraft. advance. [0003] At present, the methods for controlling the transformation of each stage in the whole process of flight test include the evaluation of the achievement of established mission goals, airworthiness or safety evaluation, flight risk analysis, failure analysis, aircraft state evaluation, flight condition evaluation and quality control, etc., but these Basically, it is a one-time evaluation or review for flight mission events, involving how to perform transition cont...
