Aircraft engine and method for operating an aircraft engine

摘要

An aircraft engine includes at least one electrical apparatus, which can be driven by a driveshaft in order to generate electrical energy. A hydrodynamic torque converter, with guide blades, which can be adjusted via a mechanism, is arranged between the driveshaft and the electrical apparatus. The guide blades are adjusted as a function of a rotational speed of the driveshaft, wherein the rotational speed of a shaft of the electrical apparatus operated as a generator can be adjusted, essentially within a predefined rotational speed range, via the adjustment of the guide blades.

主权项

1. An aircraft engine comprising:
a driveshaft; an electrical apparatus, driven by the driveshaft, to generate electrical energy, a hydrodynamic torque converter with adjustable guide blades arranged between the driveshaft and the electrical apparatus; an adjustment mechanism for adjusting a position of the guide blades; a coupling mechanism arranged between the driveshaft and a shaft of the electrical apparatus, via which a drive torque generated by the electrical apparatus when operated as a motor can be supplied in a direction of the driveshaft; wherein the coupling mechanism includes a switch element, via which the hydrodynamic torque converter can be bypassed during a starting sequence performed by the drive torque generated by the electrical apparatus.
