Abstract
A fan casing assembly for a turbine engine including a fan casing having a peripheral wall, a surface cooler having a first surface confronting the peripheral wall and a mounting assembly having a lower portion generally retained between the first surface of the annular surface cooler and the peripheral wall and having a floating body extending through the set of fan casing fastener openings and an upper portion located radially exterior of the annular fan casing and operably coupled to the lower portion.
Claims19
A mounting assembly, comprising:
- a first self-contained assembly, comprising:
- a washer having a body defining a first side and a second side and including at least one fastener opening extending through the body from the first side to the second side;
- at least one washer including a peripheral lip and a central hub having a fastener opening;
- a biasing element located between the second side of the washer and the at least one washer;
- at least one bushing having an internally threaded section;
- and
- at least one fastener having a threaded section, the threaded section configured to pass through the at least one fastener opening, the fastener opening, and be retained in the internally threaded section of the at least one bushing and having a length that passed through the at least one bushing and provides for a pre-load force;
- at least one second self-contained assembly, comprising:
- a boss having a body extending from a first distal surface to a second distal surface, a passage of the boss extends through the body of the boss from the first distal surface to the second distal surface, a first seat is defined within the passage;
- a floating body having a shank and a cap extending from an upper portion of the shank, an internally threaded passage extends through the shank and cap, the shank located within the passage at a first side of the cap configured to abut the first seat defined within the passage, and a second side of the cap is retained between the first distal surface and the first seat;
- and
- a retainer configured to contact a second seat, wherein both the retainer and the second seat are disposed within the passage;
- and
- wherein the threaded section of the at least one fastener can be received and retained in the internally threaded passage of the shank to operably couple the first self-contained assembly and the at least one second self-contained assembly.

A fan casing assembly, comprising:
- an annular fan casing having a peripheral wall and a set of fan casing fastener openings passing through the peripheral wall;
- an annular surface cooler having a first surface confronting the peripheral wall;
- and
- a mounting assembly having a lower portion generally retained between the first surface of the annular surface cooler and the peripheral wall and having a floating body extending through the set of fan casing fastener openings and an upper portion located radially exterior of the annular fan casing and operably coupled to the lower portion, wherein the mounting assembly is configured to provide a fixed connection for dynamic loading, a flexible connection for thermal loading, and shifting during installation to allow for tolerance mismatch of the annular fan casing and annular surface cooler;
- wherein the mounting assembly includes a first self-contained assembly, comprising:
- a washer having a body defining a first side facing an exterior of the peripheral wall of the annular fan casing and a second side and including at least one fastener opening extending through the body from the first side to the second side;
- at least one washer including a peripheral lip and a central hub having a fastener opening;
- a biasing element located between the second side of the washer and the at least one washer;
- at least one bushing having an internally threaded section;
- and
- at least one fastener having a threaded section, the threaded section configured to pass through the at least one fastener opening, the fastener opening, and be retained in the internally threaded section of the at least one bushing and having a length that passed through the at least one bushing and provides for a pre-load force;
- and
- at least one second self-contained assembly, comprising:
- a boss having a body extending from a first distal surface to a second distal surface, a passage of the boss extends through the body of the boss from the first distal surface to the second distal surface, a first seat is defined within the passage, the first distal surface operably coupled to the first surface of the annular surface cooler;
- a floating body having a shank configured to pass through one of the set of fan casing fastener openings and a cap extending from an upper portion of the shank, an internally threaded passage extends through the shank and cap, the shank located within the passage and a first side of the cap configured to abut the first seat defined within the passage, and a second side of the cap is retained between the first distal surface and the first seat;
- and
- a retainer washer configured to contact a second seat, wherein both the retainer washer and the second seat are disposed within the passage;
- and
- wherein the threaded section of the at least one fastener can be received and retained in the internally threaded passage of the shank to operably couple the first self-contained assembly and the at least one second self-contained assembly.
