BLADE ARRANGEMENT OF A JET ENGINE OR AN AIRCRAFT PROPELLER

摘要

A blade arrangement of a jet engine or an aircraft propeller including a blade with a root portion and an aerofoil portion, wherein the aerofoil portion includes a suction side and a pressure side. The blade arrangement further includes a retention structure that is configured to radially retain the blade in case of a structural blade failure, wherein the retention structure is secured to the root portion and/or to a structure adjacent to the root portion and extends in the radial direction along the suction side and along the pressure side of the aerofoil portion. The retention structure forms a loop that runs at least around the root portion, along the suction side and along the pressure side of the blade.
