Unbalance Response Analysis of Twin Spool Aero-Gas Turbine Engine
Megha Mohan  | Shruthi Raj | Disa Jaison
Abstract: Twin spool Aero-gas turbine engine is rotating equipment having two rotors called low pressure (LP) Spool and high pressure (HP) Spool. The rotors are mainly assembly of axial flow compressor and axial turbine connected by shaft. The rotors are designed to rotate at wide range of rotational speeds to meet operational requirement. During this regime of speeds, rotor mechanical behavior is very critical in terms of its vibratory behavior. The vibratory behavior of rotor is analyzed by specialized technique called Rotor dynamics. In brief, rotor dynamics computes critical unbalance response of rotor.
