Abstract:
Based on the research on the motion law of the drilling fluid along the blade, the necessary condition of the blade shape for a high efficiency turbodrill is obtained. Hence a mathematical model how to design a blade shape has been put forward, and the solution method of the model is obtained, which helps to design a high efficiency turbodrill. What's more, a 3 dimension model of the blade has been set up using Pro/E software, which can link with the advanced computer language by a interface routine and modify the 3-D blade model automatically. Based on the theory, a software has been compiled to design the blade automatically, which can improve the design efficiency and the design quality of the turbodrill.
