Abstract

A universal airplane jet engine turbine blade packing case assembly for securely holding a matched turbine blade pair of various shapes, sizes, and profiles for safe shipping and storage includes a molded housing having a base and a hinged lid, with the housing being partitioned into two sections, one section for each turbine blade. Each section includes a dial rotatably affixed to the inside of the base, with a tapered slot in the dial for slidably receiving and engaging a turbine blade root when the slot is in a vertical loading position. When the root has been slid into the dial, rotating the turbine blade causes the dial to also rotate, which causes the slot opening to rotate behind a portion of the housing such that the turbine root is now positively held within the dial. The turbine blade and dial are rotated further until the turbine blade chord is aligned vertically in a stow position. The dial has detentes molded into it, such that rotating the dial causes the dial to lock into any one of a number of stow positions to accommodate turbine blades having a variety of root-to-chord angles. In the stow position, when the lid is closed a pair of foam pads securely hold the turbine blade tip by its leading and trailing edges. The assembly allows safe shipping and storage, along with quick packing and unpacking, of a pair of turbine blades of any one of a number of turbine blade models.
