  • Method of a continuous determination of an instantaneous position of an impeller blade tip in a rotor turbine machine
    Patent number: 6833793
    Abstract: The invention relates to a method of a continuous determination of an instantaneous position of an impeller blade tip (5′) in a rotor turbine machine, particularly in a turbine impeller (6) in a turbojet engine during its operation in a real condition in order to obtain a current information on a technical state of the blade (5). In a selected place of an housing (7) of a rotor turbo machine, in a movement plane of impeller blade tips (5′), it is arranged in a stable manner at least one microwave antenna (3) with an aperture shape (4) which is consistent with an internal surface of an housing (7). The microwave signal (11), which is produced by a microwave homodyne system, is emitted, and then received, through a microwave antenna (3). The output signal (9) from that system, which carries out information on each instantaneous position of an impeller blade tip (5′) in relation to an antenna aperture (4), is converted by an electronic system, and then it is read.
