Abstract
A mount system for coupling an engine with a frame includes a yoke that has two limbs that couple with the engine and that has a hub from which the two limbs extend. The yoke also couples with the frame. The yoke includes separate pieces that may be formed separate from one another and that join together around the hub, with plate sections of the pieces having overlapping parts that define mating surfaces between the pieces. Apertures are defined through the plate sections and the hub to receive pins for securing the pieces together. A plural number of shear planes are defined by the overlapping parts at each of the apertures and pins.

A mount system for coupling an engine with a frame, the mount system
- comprising:
- a yoke having two limbs each configured to couple with the engine and having a
- hub from which the two limbs extend, the yoke configured to couple with the frame,
- wherein the yoke is comprised of at least two pieces that join together around the hub, with plate sections of the at least two pieces having overlapping parts that define mating surfaces between the at least two pieces,
- wherein apertures are defined through the at least two pieces at the plate sections,
- wherein the apertures are configured to receive pins for securing the at least two pieces together, and
- wherein a plural number of shear planes are defined by the overlapping parts at each of the apertures and the pins.
A mount system for coupling an engine with a frame, the mount system
- comprising:
- a yoke having a first limb and a second limb, the first limb and the second limb configured to couple with the engine and having a hub from which the first and second limbs extend, the yoke configured to couple with the frame,
- wherein the yoke is comprised of separate pieces that include the first limb, the second limb, and the hub,
- wherein the first limb and the second limb join together around and with the hub, with plate sections of the first limb, the second limb, and the hub having overlapping parts that define mating surfaces between the first limb, the second limb, and the hub,
- wherein apertures are defined through the plate sections of each of the first limb, the second limb, and the hub,
- wherein the apertures are configured to receive pins for securing the first limb, the second limb, and the hub together, and
- wherein a plural number of shear planes are defined by the overlapping parts at each of the apertures and the pins.
A mount system for coupling an engine with an airframe, the mount system
- comprising:
- a yoke having a first limb, a second limb and a hub from which the first and second limbs extend, the first limb, the second limb and the hub each configured to couple with both the engine and with the airframe,
- wherein the yoke is assembled from separate pieces that include the first limb, the second limb, and the hub,
- wherein the first limb and the second limb join together around and with the hub, with plate sections of the first limb, the second limb, and the hub having overlapping parts that define mating surfaces between the first limb, the second limb, and the hub,
- wherein the plate sections have pads extending from the mating surfaces, wherein the pads are configured to define a contact slip fit between the first limb and the hub, and between the second limb and the hub
- wherein apertures are defined through the plate sections of each of the first limb, the second limb, and the hub,
- wherein the apertures are configured to receive pins for securing the first limb, the second limb, and the hub together, and
- wherein a plural number of shear planes are defined by the overlapping parts at each of the apertures and the pins.
