Abstract

An engine support assembly for operatively connecting an engine to an aircraft, the aircraft, the aircraft having a support frame surrounded by opposing first and second skins. The engine support assembly broadly comprises first and second support structures. The first support structure is secured to the support frame and extends away from the first skin. The second support structure is releasably connected to the first support structure and releasably connected to the engine.

Claims (19)

1. An engine support assembly for operatively connecting an engine to an aircraft, the aircraft having a support frame surrounded by a first skin and an opposing second skin, the engine support assembly comprising:

a first support structure configured to be secured to the support frame, wherein the first support structure is configured to extend from the support frame and away from the first skin; and

a second support structure releasably connected to the first support structure and configured to be releasably connected to the engine;

wherein the first support structure includes a first attachment member and a second attachment member spaced apart from the first attachment member, and wherein the second support structure includes a first attachment member and a second attachment member spaced apart from the first attachment member;

wherein the second support structure includes a first backbone section connected to a first apex of the first attachment member of the second support structure and configured to be releasably connected to a first attachment point of the engine.

2. The engine support assembly of claim 1 , wherein the first attachment members are releasably connected to each other and the second attachment members are releasably connected to each other.

3. The engine support assembly of claim 2 , wherein both the first and second attachment members of the first support structure include a stem configured to extend away from the support frame.

4. The engine support assembly of claim 3 , wherein each of the first attachment member and the second attachment member of the first support structure includes opposing legs extending away from the stem.

5. The engine support assembly of claim 1 , wherein the first attachment member and the second attachment member of the first support structure are configured to cradle a first portion of the engine and the first attachment member and the second attachment member of the second support structure are configured to straddle a second portion of the engine opposite the first portion of the engine so that the first support structure and the second support structure cooperatively encircle the engine entirely.

6. The engine support assembly of claim 1 , wherein the second support structure further includes a second backbone section connected to the first apex of the first attachment member of the second support structure and a second apex of the second attachment member of the second support structure, and wherein the second backbone section is configured to be releasably connected to a second attachment point of the engine.

7. A quick engine change module for an aircraft, the aircraft having a support frame and a first support structure, the quick engine change module comprising:

an engine, the engine having a first portion configured to be received in the first support structure of the aircraft such that the first portion is cradled by the first support structure, the engine further comprising a second portion opposite the first portion;

a second support structure configured to be releasably connected to the first support structure, the second support structure connected to the engine and straddling the second portion of the engine, wherein when the second support structure is releasably connected to the first support structure, the first support structure and the second support structure cooperatively encircle the engine entirely;

wherein the second support structure includes a first attachment member and a second attachment member spaced apart from the first attachment member, the first attachment member including a first apex;

wherein the second support structure includes a first backbone section connected to the first apex of the first attachment member of the second support structure and configured to be connected to a first attachment point of the engine.

8. The support assembly of claim 7 , wherein the quick engine change module further comprises a portion of a nacelle including an inlet.

9. The support assembly of claim 7 , wherein the quick engine change module further comprises an exhaust nozzle.

10. The support assembly of claim 7 , wherein the quick engine change module further comprises a portion of a nacelle including inner flow surface panels.

11. The support assembly of claim 7 , wherein the quick engine change module further comprises a portion of a nacelle including a plurality of bypass flow modules directly or indirectly connected to the second support structure thereby supplementing rigidity of the second support structure.
