  • Tools for mounting a turbo aero engine distributor
    Patent number: 5918356
    Abstract: Tooling for mounting angular sectors (8) of a distributor vane grid in a turbo aero engine casing (1), especially for a low pressure turbine. The mounting edge of the sectors (8) includes projections whose disposition requires a particular extremely precise movement to embody mounting. This is effected by using a set of tools including the support plates (58) of the sectors (8) suspended by connecting rods (60 and 61) from a circular plate (51) able to move vertically so as to start the engagement of the sectors (8) in their throat (84). The connecting rods (60 and 61) are disposed so as to enable the support (58) to move backward and be slanted and thus move back the projections of the uneven sectors (8) of the casing (1) and then engage them in the throat.
