Abstract:
The design and manufacture of liquid rocket engine thrust chamber is a very complicated system engineering. The performance parameters, structure form, organization mode and selection of materials, in particular, rely on the designer's experience and design knowledge of successful development model. To improve the reusability of existing experience in the design of thrust chamber of liquid rocket engine, the case-based reasoning method was utilized in the design. Case-based reasoning method is an important branch in the field of artificial intelligence, with which the examples to solve typical problems in the past are stored according to a and design characteristics of a liquid rocket engine thrust chamber. The case representation methodand case adjustment scheme of the thrust chamber are proposed on the basis of the case-based reasoning method. The case adjustment was realized by this technology.
