A centrifugal blower is a mechanical device for moving air or other gases. The terms blower and  “squirrel cage fan”; (because it looks like a hamster wheel) are frequently used as synonyms. Rotating impellers increase the speed of the air blowing from other end. They use the kinetic energy of the rotating blade or impeller to increase the pressure and tends to slightly decrease velocity of the air/gas stream which in turn moves them against, dampers and other components which causes the resistance. This project is static and dynamic analysis of centrifugal blowers using composite materials Centrifugal blowers are used in naval applications and motors which have high noise levels. The noise generated by a rotating component is mainly due to random loading force on the blades and periodic iteration of incoming air with the blades of the rotor. The Contemporary blades in naval applications are made up of Aluminum or Steel and generate noise that causes disturbance to the people working near the blower. The present work aims at observing the choice of HM Carbon as an alternative to metal for better vibration control. HM Carbon, known for their superior damping characteristics are more promising in vibration reduction compared to metals. The modeling of the blower was done by Unigraphics. It is proposed to design blower with HM Carbon, analyze its strength and deformation using FEM technique. In order to evaluate the effectiveness of HM Carbon and metal blower using FEA packaged (ANSYS). Modal analysis is performed on both Aluminium and HM Carbon blower to find out first five natural frequencies.
