Abstract
An aircraft propulsion system includes an engine assembly including a fan that moves air, and a cowl that surrounds at least a portion of the engine assembly when the cowl is in a closed position. The cowl includes an outer surface arranged away from the engine assembly that provides an aerodynamic surface. The aircraft propulsion system also includes a cowl mechanism connected to the cowl and configured to guide the cowl along a movement path from the closed position to an open position. In the open position, an entirety of the cowl is arranged farther away from a horizontal plane passing through a rotating axis of the fan than in the closed position.
Claims20
An aircraft propulsion system comprising:
- an engine assembly including a fan that rotates to move air;
- a cowl that surrounds at least a portion of the engine assembly when the cowl is in a closed position, the cowl including an outer surface arranged away from the engine assembly that provides an aerodynamic surface;
- and
- a cowl mechanism connected to the cowl and configured to guide the cowl along a movement path from the closed position to an open position, wherein
- in the open position, an entirety of the cowl is arranged farther away from a horizontal plane passing through a rotating axis of the fan than in the closed position.
A cowl movement mechanism that connects to at least one cowl configured to surround at least a portion of an engine assembly in a closed position of an aircraft propulsion system, the engine assembly including a fan that rotates to move air, and the at least one cowl including an outer surface arranged away from the engine assembly that provides an aerodynamic surface, the cowl movement mechanism comprising:
- a plurality of links configured to guide the at least one cowl along a movement path from the closed position to an open position;
- and
- the plurality of links are configured to guide the at least one cowl along the movement path so that an entirety of each cowl in the at least one cowl is moved farther away from a horizontal plane passing through a rotating axis of the fan than in the closed position.
