Abstract
A gas turbine engine includes a seal assembly that is supported by a member at a joint. The seal assembly includes a seal support having a radial flange secured to the joint. A first bend adjoins the radial flange to a first leg, which is oriented generally in an axial direction. A second bend adjoins the first leg to a second leg, which is conical in shape. A seal is supported by the second leg.
Claims16
A gas turbine engine comprising:
- a seal assembly supported by a member at a joint, the seal assembly including a seal support having a radial flange secured to the joint, a first bend adjoins the radial flange and a first leg, which extends from the radial flange generally in a first axial direction, a second bend adjoins the first leg to a second leg, which is conical in shape, wherein the first and second legs are tangential to opposing ends of the second bend, the second leg extends from the second bend generally in a second axial direction that is opposite of the first axial direction to provide a fold, the first and second legs and first and second bends provided by an integral member, the second leg provides a channel at a portion not adjoining the second bend and the first leg;
- and
- a seal carried by the channel.
A gas turbine engine, comprising:
- a fan;
- a compressor section fluidly connected to the fan, the compressor comprising a high pressure compressor and a low pressure compressor;
- a combustor fluidly connected to the compressor section;
- a turbine section fluidly connected to the combustor, the turbine section comprising:
- a high pressure turbine;
- a low pressure turbine coupled to the low pressure compressor via a shaft;
- a geared architecture interconnects between the shaft and the fan;
- a seal assembly provided in at least one of the compressor and turbine sections, the seal assembly supported by a mid turbine frame at a joint, the mid turbine frame arranged between the high and low pressure turbines, the seal assembly including a seal support having a radial flange secured to the joint, a first bend adjoins the radial flange to a first leg, which extends from the radial flange generally in a first axial direction, a second bend adjoins the first leg to a second leg, which is conical in shape, wherein the first and second legs are tangential to opposing ends of the second bend, the second leg extends from the second bend generally in a second axial direction that is opposite of the first axial direction to provide a fold, the first and second legs and first and second bends provided by an integral member, the second leg provides a channel at a portion not adjoining the second bend and the first leg;
- and
- a seal carried by the channel.
