Improved Rotor Balance Process

This entry focuses upon the process of rotor balance. The term rotor refers to the type found in jet engines. During the engine assembly process, rotors must be balanced to a very high level of precision. Rotors are typically balanced by using a device called a balance machine. If a rotor is not properly balanced, the engine will vibrate in the field (i.e. on-wing). Vibration causes efficiency loss and undesirable engine wear.

Data shows that rotors which achieve a passing score from a balance machine are not necessarily going to pass in the field. There are external inputs that can effect the balance machine's process. The author has discovered a method to largely improve the rotor balance process accuracy and repeatability. Using the improved method, data from over 300 rotors proves the average unbalance to be 90% closer to zero unbalance and yields zero customer turnbacks.

Thank you for your time reviewing and considering this entry.
