Abstract

Blade is a sensitive and important part of turbines, and a few companies can produce it. Airfoil of blade has three-dimensional surfaces; therefore, it is necessary to have specific equipment for dimensional control of it. The purpose of this project is to design and manufacture a mechanical system for dimensional control of the airfoil. The foregoing device can produce two-dimensional contours of airfoil on the screen of the PROFILE PROJECTOR using fine pins. In the mentioned system, the blade is located on the table of device and two sets of pins approach it. In this situation pins are moved forward along their axis until their tips touch the surface of the blade, therefore the tips of pins, shape the contour of the airfoil. Then two sets of pins get away from each other and are moved to the focal area of lens of PROFILE PROJECTOR via a precision linear system. Then two sets of pins approach each other and reshape the previous contour again. In this situation, tips of pins are projected and contour of airfoil is made on the screen of the PROFILE PROJECTOR with a predefined scale. Produced contours can be compared with reference ones that have been printed on transparent sheets.
