Abstract

Disclosed herein is an aircraft that includes an exhaust manifold for combining one or more system exhaust paths located upstream of equipment inlets and directing the exhausts upwards towards the rotor linkages such that the exhaust is expelled and diffused forward of the equipment inlets. According to one aspect of the present disclosure, the exhaust manifold includes a structure for supporting a transmission cowling at the top of the aircraft and/or on the sides of the aircraft. For example, the exhaust manifold may include a platform that contains the exhaust ducts and may include a frame extending from the platform that follows the contours of the cowling, such that the cowling lays along the support frame for additional mechanical support.

First claim

What is claimed is:

1. An exhaust manifold for an aircraft comprising:
a plurality of exhaust ducts in gaseous communication with one or more exhaust systems, wherein the exhaust ducts receive exhaust from the one or more exhaust systems; and
a platform comprising the plurality of exhaust ducts, wherein the platform is located upstream of an equipment inlet, and wherein the plurality of exhaust ducts are configured to direct exhaust at a rotor linkage for the exhaust to dissipate away from one or more rotors attached to the rotor linkage.

2. The exhaust manifold of claim 1 , wherein the one or more exhaust systems include one or more of a transmission, an oil cooling, a generator, and an environmental control system.

3. The exhaust manifold of claim 1 , further comprising:
a cowl, wherein the platform is attached to the cowl; and
a cowl support structure, wherein the cowl support structure supports the cowl to which the platform is attached.

4. The exhaust manifold of claim 3 , wherein the cowl support structure matches a contour of the cowl.

5. The exhaust manifold of claim 3 , wherein the cowl support structure matches a portion of a contour of the cowl.

6. An apparatus, comprising:
a plurality of exhaust ducts in gaseous communication with one or more exhaust systems, wherein the exhaust ducts receive exhaust from the one or more exhaust systems; and
a platform comprising the plurality of exhaust ducts, wherein the platform is located upstream of an equipment inlet, and wherein the plurality of exhaust ducts direct exhaust at a rotor linkage for the exhaust to dissipate away from one or more rotors attached to the rotor linkage.

7. The apparatus of claim 6 , wherein the one or more exhaust systems include one or more of a transmission, an oil cooling, a generator, and an environmental control system.

8. The apparatus of claim 6 , further comprising:
a cowl, wherein the platform is attached to the cowl; and
a cowl support structure, wherein the cowl support structure supports the cowl to which the platform is attached.

9. The apparatus of claim 8 , wherein the cowl support structure matches a contour of the cowl.

10. The apparatus of claim 8 , wherein the cowl support structure matches a portion of a contour of the cowl.

11. A rotorcraft, comprising:
an engine;
an engine inlet;
a rotor linkage; and
an exhaust manifold comprising:
a plurality of exhaust ducts in gaseous communication with one or more exhaust systems, wherein the exhaust ducts receive exhaust from the one or more exhaust systems; and
a platform comprising the plurality of exhaust ducts, wherein the platform is located upstream of the engine inlet, and wherein the plurality of exhaust ducts are configured to direct exhaust at the rotor linkage for the exhaust to dissipate away from one or more rotors attached to the rotor linkage.

12. The rotorcraft of claim 11 , wherein the one or more exhaust systems include one or more of a transmission, an oil cooling, a generator, and an environmental control system.

13. The rotorcraft of claim 11 , further comprising:
a cowl, wherein the platform is attached to the cowl; and
a cowl support structure, wherein the cowl support structure supports the cowl to which the platform is attached.

14. The rotorcraft of claim 13 , wherein the cowl support structure matches a contour of the cowl.

15. The rotorcraft of claim 13 , wherein the cowl support structure matches a portion of a contour of the cowl.
