Three dimensional scanning of aircraft blade
Aircraft blade is an important component of turbine section in gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the operation of the engine. Whether steam turbine engine or gas turbine engine, blade metal fatigue is the main cause of engine failure. Strong vibration or resonance may lead to metal fatigue.

Practical problems
1. Aircraft engine blades generally bear large working stress and high working temperature, and the changes of stress and temperature are frequent and violent. In addition, there are corrosion and wear problems. They have very strict requirements for working conditions, so they require high machining accuracy.
2. At the same time, in order to improve the efficiency of turbine, the surface shape of turbine blade is usually designed as twisted variable cross-section surface, and the shape is complex. Therefore, the accurate geometric modeling of turbine blades has become a necessary prerequisite for aircraft machining.
3. For the airfoil cross-section area, alignment, blade contour, trailing edge radius and blade root shape, three-dimensional measurement needs to be carried out in a nondestructive manner, which is a challenge to the traditional measurement methods.
