PURPOSE: A starting torque measuring device of a gas turbine engine is provided to reduce manufacturing costs by using a power lock coupling and to simplify the configuration. CONSTITUTION: A starting torque measuring device of a gas turbine engine comprises a first shaft(100), a second shaft(200), a torque measuring unit(300), a power lock coupling(400), and an adapter. The first shaft is axis-connected to a rotary shaft of a gas turbine engine. The second shaft is axis-connected to a rotary shaft of an air turbine starter. The torque measuring unit is connected to a first rotary shaft(310) which is connected to the first shaft and the second shaft. The torque measuring unit comprises a second rotary shaft(320) rotating while communicating with the first rotary shaft. The first shaft, the second shaft, the first rotary shaft, and the second rotary shaft are arranged along a coaxial line and are joined with the rotary shaft of the air turbine starter by the power lock coupling, thereby rotating by being combined. |
