Abstract
A bracket includes a rigid member and a resilient member for coupling a coolant collector to a coolant supply manifold. The coolant collector is movable between a first position and a second position with respect to the coolant supply manifold due to thermal heating. The resilient member defines an anchoring portion and a cantilevered portion. The anchoring portion couples the cantilevered portion to a midsection of the rigid member for urging the coolant collector toward the coolant supply manifold in the first and second positions.
Claims14
A bracket, comprising:
- a rigid member configured for coupling a coolant collector to a coolant supply manifold, wherein the coolant collector is movable between a first position and a second position spaced apart from the first position due to thermal expansion;
- and
- a resilient member with an anchoring portion and a cantilevered portion, wherein the anchoring portion is coupled to the rigid member, wherein the cantilevered portion extends from the anchoring portion and overhangs an end of the rigid member for urging the coolant collector member toward the coolant supply manifold in both the first and second positions, wherein the rigid member and an end of the resilient member cantilevered portion define registered apertures.
A clearance control system for a gas turbine engine, comprising:
- a coolant supply manifold;
- a coolant collector displaceable between first and second positions in relation to the coolant supply manifold due to thermal expansion;
- a bracket coupling the coolant collector to the coolant supply manifold, including:
- a rigid member overlying the coolant collector;
- and
- a resilient member with an anchoring portion and a cantilevered portion, wherein the anchoring portion couples the cantilevered portion to the rigid member, wherein the cantilevered portion overhangs an end of the rigid member;
- and
- a fastener extending through the cantilevered portion and seated in the coolant supply manifold, wherein the fastener fixes the cantilevered portion with respect to the coolant supply manifold for applying force to and urging the coolant collector toward the coolant supply manifold in the first and second coolant collector positions.
A gas turbine engine, comprising:
- a turbine case;
- a coolant supply manifold extending about the turbine case;
- a coolant collector coupled to the turbine case with a support, wherein the support displaces the coolant collector from a first position to a second position due to thermal expansion;
- a bracket coupling the coolant collector to the coolant supply manifold, including:
- a rigid member overlying the coolant collector;
- a resilient member with an anchoring portion and a cantilevered portion, wherein the anchoring portion couples the cantilevered portion to the rigid member, wherein the cantilevered portion overhangs an end of the rigid member;
- and
- a fastener extending through the cantilevered portion and seated in the coolant supply manifold, wherein the fastener fixes the cantilevered portion with respect to the coolant supply manifold for applying force urging the coolant collector toward the coolant supply manifold in the first and second coolant collector positions.
