What Are the Different Types of Aerospace Engineering Programs?

Aerospace systems engineering is an organization and management technology for aerospace and aerospace engineering. Organize and manage the planning, research, design, manufacturing, testing, and application of aerospace systems based on the ideas of systems science, applying the theories of operations research, information theory, and cybernetics, and using information technology as a tool. ^[1]

The fundamental starting point of aerospace system engineering is to make the most effective use of the latest scientific and technological achievements, obtain the highest economic benefits, and achieve the expected purpose of aerospace at the least cost (human, material, financial and time).

Aerospace system engineering main features

The main feature of system engineering is the quantification of systematic thinking methods, that is, the mathematical method of quantitatively processing the interrelationships between the various components of the system; at the same time, electronic computers are used as computing means. Computers are an indispensable tool when dealing with system engineering problems with complex relationships.

Aerospace system engineering development

Aerospace system engineering is the earliest developed system engineering. The United States and the Soviet Union have applied systems engineering principles to aerospace engineering. China's aerospace engineering has also been organized and managed in accordance with the principles of systems engineering under the guidance of Qian Xuesen. The aerospace system is a relatively typical complex large system in modern times. For example, the large systems when a spacecraft is launched include: spacecraft, carrier spacecraft launching sites, and aerospace measurement and control systems (including measurement and control stations, measurement boats, and measurement aircraft) distributed in various places. , Spacecraft recovery facilities, user stations (networks), etc. These systems or equipment are also complex systems, each consisting of a number of sub-systems and many devices. For such a large and complex system, the design, manufacture, testing and application of each component need to have unified and coordinated technical requirements in order to make the entire system operate in a coordinated manner; all units undertaking research and development must use a unified plan and coordinate Only highly centralized scheduling of programs can make the research and development work in the optimal management state, so that the research and development costs are the least, and the time is the shortest. The test launch was also carried out under the unified command of the same information control center. All stations and stations should act in unison, and all work should be coordinated. The most scientific way to accomplish these difficult and complex overall coordination tasks is a systems engineering approach. ^[1]

Aerospace systems engineering aviation method

Use command information system to implement scientific plan management for aerospace engineering. An efficient database is formed by the electronic computer, which continuously displays the historical situation and latest progress of various tasks, and quickly processes the frequently changing progress of the plan, so that plan managers can grasp the overall dynamics of the plan in time and find weak links. Network models and electronic computers are used to simulate the measures taken to predict the effects of the measures, provide a basis for decision-making, and select the best manpower, material and financial dispatching plan.

Establish a chief designer system, and the overall design agency, the overall design department, performs scientific and technical management (also called technical coordination) of large-scale social labor such as aerospace engineering. This design department is composed of professional and technical personnel who are familiar with all aspects of the large system. Under the leadership of the chief designer, according to the requirements of the task, the method of operation research is used to carry out systematic index demonstration and overall plan assumptions. (Feasibility and feasibility) demonstration, process design, and system environment analysis to determine the overall plan; choose the overall parameters and shape, determine the system's composition, function, and index allocation, combine the sub-systems into an organic whole, from the entire large system The design parameters and technical requirements of each sub-system are set forth (see aircraft design). At the same time, draft a test plan, carry out the overall design of the test work and use methods, propose technical requirements for various test and use facilities, or make recommendations for the use or modification of existing test and use facilities. Throughout the aerospace engineering, the overall design agency coordinates the contradictions between the various sub-systems and the work of large-scale system tests, and chooses the solution.

Use simulation technology, including digital simulation and physical simulation. In order to optimize the system scheme and coordinate the system components, the entire system analysis and synthesis need to be performed in the scheme demonstration and system design. Computer simulation and simulation technology are used to reasonably select the system parameters and schemes, and to engineer the system. Analysis, reliability analysis and forecasting. ^[1]
