A seal for sealing the gaps between adjacent turbine blade structures is disclosed in which the seal is disposed in a compartment formed between adjacent turbine blade structures having first and second sealing surfaces adjacent to a generally axially extending gap and a generally radially extending gap, respectively. The seal also has a thrust surface extending obliquely to a radius from the axis of rotation of the rotor disk to which the turbine blade structures are attached which is engaged with a reaction surface formed on a reaction member located in the compartment. During rotation of the rotor disk, centrifugal force acting in a radially outward direction is transmitted both radially and axially to a seal by contact between the reaction surface and the oblique thrust surface to cause the first sealing surface to seal the generally axially extending gap and the second sealing surface to seal the generally radially extending gap.

A seal for sealing gaps between adjacent turbine blade structures attached to a rotor disc rotatable about an axis, the adjacent turbine blade structures forming a generally axially extending gap and a generally radially extending gap therebetween, the seal comprising: a) a compartment formed by adjacent turbine blade structures; b) seal means located in the compartment and having a first sealing surface adjacent to the generally axially extending gap, a second sealing surface adjacent to the generally radially extending gap and a thrust surface extending obliquely to a radius from the axis; and c) a member in the compartment having a reaction surface located such that, during rotation of the rotor disc, centrifugal force in a radial direction is transmitted radially and axially to the seal means via contact between the reaction surface and the oblique thrust surface, thereby causing the first sealing surface to seal the generally axially extending gap and the second sealing surface to seal the generally radially extending gap.
