Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
An engine thrust mount construction for transmitting thrust from the engine to an airframe structural member comprising: an engine casing; a pair of flanges connected to the engine casing, the flanges being spaced from one another and forming a circumferential groove therebetween; a boss connected to the engine casing, the boss being positioned within the circumferential groove; a thrust bracket positioned within the circumferential groove, the thrust bracket cooperating with the boss and the airframe structural member to transmit the thrust from the engine to the airframe structural member; and the thrust bracket including a pair of flanges spaced axially from one another, these flanges straddling the boss and the thrust bracket including means for eliminating any binding due to misalignment between the structural member and the engine.
Claim 2
Dependent Claim
128 words
An engine thrust mount construction for transmitting thrust from the engine to an airframe structural member comprising: an engine casing; a pair of flanges connected to the engine casing, the flanges being spaced from one another and forming a circumferential groove therebetween; a boss connected to the engine casing, the boss being positioned within the circumferential groove; a thrust bracket positioned within the circumferential groove, the thrust bracket cooperating with the boss and the airframe structural member to transmit the thrust from the engine to the airframe structural member; and the thrust bracket including a pair of flanges spaced axially from one another, these flanges straddling the boss and the thrust bracket including means for eliminating any binding due to misalignment between the structural member and the engine.
Claim 3
Dependent Claim
43 words
An engine thrust mount construction as in claim 1 wherein the means is a spherical bearing, the structural member being positioned within an internal opening in the bearing and cooperating therewith and the thrust bracket is positioned around the bearing and cooperating therewith.
Claim 4
Independent Claim
106 words
A device for mounting a gas turbine engine in an aircraft installation comprising: An engine casing having an integral thrust flange extending outwardly therefrom; a pair of outwardly extending projections connected to the casing, the projections being spaced from one another to form a circumferential slot within which the thrust flange is positioned; a thrust bracket positioned within the cirCumferential slot and connected to the outward projections, the thrust bracket including means for transmitting the thrust loads from the thrust flange to a structural member of the aircraft; and bearing means mounted on the bracket to eliminate any misalignment between the engine and its structural member.
Claim 5
Independent Claim
106 words
A device for mounting a gas turbine engine in an aircraft installation comprising: An engine casing having an integral thrust flange extending outwardly therefrom; a pair of outwardly extending projections connected to the casing, the projections being spaced from one another to form a circumferential slot within which the thrust flange is positioned; a thrust bracket positioned within the cirCumferential slot and connected to the outward projections, the thrust bracket including means for transmitting the thrust loads from the thrust flange to a structural member of the aircraft; and bearing means mounted on the bracket to eliminate any misalignment between the engine and its structural member.
Claim 6
Dependent Claim
50 words
A device for mounting an engine as in claim 3 wherein the means for transmitting the thrust loads from the thrust flange to the thrust bracket comprise a pair of inwardly extending fingers, the fingers being spaced from one another and being positioned on opposite sides of the thrust flange.
Claim 7
Dependent Claim
55 words
A device for mounting an engine as in claim 3 wherein the thrust bracket is positioned between the projections so that a gap exists therebetween, and the thrust bracket is supported from the projections by a plurality of pins, the pins transmitting any couple-type loads produced in the thrust bracket to an engine structural member.
Claim 8
Dependent Claim
55 words
A device for mounting an engine as in claim 5 wherein the bearing means is a spherical bearing, the aircraft structural member is a pin structure one end of which is connected to the aircraft and the other end is positioned within the spherical bearing and the thrust bracket is positioned around the spherical bearing.
