Abstract: In the modern turbomachinery design trend, blades are getting more and more flexible and loaded, and therefore prone to vibration issues due to forced response and flutter phenomena. a. It has always been important to study the development and improvement of the design of turbomachine, owing to the numerous uses of turbo machining and their high energy consumption, high performance of centrifugal compressor call for a reduction in weight to relax rotor dynamic constraints and a reduction in blade thickness as a way to improve the efficiency. This project we are focused on increasing the efficiencies, reducing the pressure loss by keeping the larger splitter blades and the enhancement of the surge characteristics and the back sweep of the blade will reduce the stall in the compressors will leads to increase the efficiency and the long operating range and this statement can be proved by conducting the forced response analysis on the compressor blades. 

Keywords: compressor blade, flutter, surge characteristics, forced response.
