High Speed Balancing Applied to the T700 Engine.
Abstract
This report presents results of T700 power turbine high-speed flexible rotor balancing evaluations and engine test cell diagnostic guidelines for the T53, T55, and T700 engines. The high-speed balancing evaluation was accomplished in two phases. The first phases used assembled T700 power turbine modules, while the final phase used a power turbine rotor assembly that permitted access to all four available balancing planes yet still incorporated engine bearing and damper assemblies. The initial tests demonstrated the feasibility of high-speed flexible rotor balancing, while the second phase of testing evaluated the approach most likely to be used in an overhaul environment.
