Abstract

The invention relates to a geared turbofan engine (10) with a sun shaft (1) driving a sun gear of planetary gearbox (14), the sun shaft (1) having a front section (A) proximal to the gearbox (14) and a rear section (B) distal from the gearbox (14), the outer diameter (D1) of the front section (A) of the sun shaft (1) is smaller than the outer diameter (D2) of the rear section (B) of the sun shaft (1) and the front section (A) of the sun shaft (1) having at least one undulant section (2A, 2B) with at least one axial part (3) of the undulant section (2A, 2B) extending in axial direction of the sun shaft (1) and two diaphragm parts (5, 6) on either side of the at least one axial part (3) extending in radial direction outward, the at least one axial part (3) of the undulant section (2A, 2B) having an inner diameter (D3) smaller than the outer diameter (D1) of the front section (A) of the sun shaft (1). The invention also relates to a sun shaft (1) driving a sun gear of a planetary gearbox (14).
