Abstract (en)
[origin: US4787817A] A device for maintaining clearance between rotor blades and a surrounding housing is disclosed in which the device radially expands or contracts to match the expansion or contraction of the rotor blade tips. The expansion or contraction of the device is achieved by thermal transfer between the device and the gasses passing over the rotor blades. The device has several alternating segments having different thermal characteristics such that the expansion/contraction characteristics of the rotor blade can be accurately matched by the device.
