The SAE ARP 4162 standard, developed by the Society of Automotive Engineers (SAE), defines rotors and a set of balancing machines proving their associated test weights, which are directly required for the evaluation of gas turbine rotor balancing machines.
Proof rotors (test rotors) are used to verify the constant balance of a balancing machine or to calibrate a rigid bearing machine. A proven rotor means savings on similar equipment rental costs for businesses and allows the balancing machine user to verify the performance of their machine as often as required by production, machine usage and quality programs. This verification can be several times a day or once a year, depending on individual circumstances.
Standard test rotors allow for the application of a known imbalance in two separate planes at various angles. Multiple weight sizes are provided to accommodate various machine sizes and speed ranges.
SAE rotors produced according to the SAE ARP 4162 standard are considered necessary to evaluate the performance of a balancing machine against the SAE ARP 4048, SAE ARP4050 and SAE ARP 532 standards. Evaluation according to these standards is generally required in aviation applications.
At various times there is a need to check whether a certain balance tolerance has been met or to verify that a balancing machine is working properly.
Jet engine vibration is often arguably an aircraft maintenance crew's worst enemy. Out of balance parts can eventually cause a cracked turbine, fan and compressor components, as well as general metal fatigue, and, if left unchecked, can eventually lead to unexpected engine failures.
Total vibration is the sum of vibration contributions from any combination of moving parts inside the engine. This makes vibration analysis and balancing extremely complex. The structural features of individual aircraft only complicate the problem. For example, the location of the engine on the frame or the type of engine mount used can communicate or exacerbate vibration problems.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides balancing machine proofing rotors testing services within the scope of SAE ARP 4162 standard, with its trained and expert staff and advanced technological equipment.
