Problems solved by technology

But generally speaking, there are still some defects, such as incomplete parameters, unclear concept of the proposed parameters, insufficient feasibility of the parameters, etc. In addition, the lack of demonstration technology and means also greatly restricts the reliability engineering in the development of military aircraft. development
Due to the relatively late development of reliability engineering technology compared with traditional weapons engineering technology, coupled with the traditional concept, that is, the combat performance is emphasized, and the existence of reliability performance is not emphasized, resulting in irregular, unreasonable and poorly scientific methods of reliability demonstration. question

Embodiment Construction

[0089] A method for demonstrating the reliability quantitative requirements of military aircraft in the present invention is based on the basic information of military aircraft. These basic information are project background and task requirements, basic equipment conditions, use schemes, initial support schemes, and reliability levels of similar military aircraft at home and abroad. information. The content of the various aspects of information is as follows:

[0090] 1) Project background and task requirements describe the development project background and mission tasks of military aircraft;

[0091] 2) The basic situation of military aircraft describes the basic composition and main functions of military aircraft;

[0092] 3) The use plan information is to determine the use plan according to the mission requirements of military aircraft development or its hypothetical use scenario, clarify the specific use requirements, and draw up the life profile in detail on this basis,...

Abstract

The invention discloses a military aircraft reliability quantitative requirement demonstration method which comprises the following steps of: 1, determining a military aircraft reliability top parameter index; 2, decomposing the military aircraft reliability top parameter index; 3, determining a threshold value of a military aircraft reliability top parameter; 4, converting a military aircraft reliability using index into a contract index; 5, comprehensively balancing the military aircraft reliability top parameter index; and 6, analyzing the technical and economic feasibilities of the military aircraft reliability top parameter index. The military aircraft reliability quantitative requirement demonstration method which is accordant with the state of China and has high operability is provided for the determination of the military aircraft reliability top parameter, so that the military aircraft reliability quantitative requirement demonstration work is guided, the reliability level of a military aircraft is lifted, the demonstration process is standardized and programmed, and the demonstration result is scientific and reasonable.

Description

1. Technical field [0001] The invention provides a method for demonstrating the reliability quantitative requirements of military aircraft, which belongs to the technical field of reliability engineering. 2. Background technology [0002] Military aircraft demonstration is a systematic analysis and design process based on the level of science and technology and economic development, with the quality and scale of existing military aircraft as the background, and scientific theories and methods as means. The demonstration of military aircraft is the first link in the development process of military aircraft and the basis of military aircraft development. Practice has proved that if the demonstration is sufficient, the project determination is more objective, the goal is clear, the requirements and indicators are more reasonable, and the military aircraft developed has a high success rate and a short cycle; Can not come out, or can't be used effectively after being developed, ...
