Abstract
A system for a thrust reverser of an aircraft includes a primary sleeve and a secondary sleeve having cascades. The secondary sleeve is coupled to a set of blocker doors. The sliding motions of the primary sleeve and the secondary sleeve are not directly coupled when each moves between its stowed and deployed positions. The sliding motion of the primary sleeve may begin at a different time and continue at a different rate from the sliding motion of the secondary sleeve.
Claims17
A thrust reverser for an aircraft, comprising:
- a first sleeve;
- a second sleeve including a cascade configured to redirect air flow, the second sleeve configured to move axially along an axis of the thrust reverser;
- and
- a blocker door coupled to the second sleeve;
- the first sleeve and the second sleeve configured to be moved by separate sliding devices;
- wherein the thrust reverser is configured such that movement of the second sleeve drives movement of the blocker door;
- and
- wherein the blocker door is configured to be stowed above a skin of the first sleeve when the thrust reverser is stowed;
- a first link coupled to the second sleeve;
- a crank coupled to the first link;
- and
- a second link coupled to the crank and to the blocker door.

A thrust reverser for an aircraft, comprising:
- a duct;
- a first sleeve;
- a second sleeve comprising a cascade configured to redirect air flow;
- a blocker door coupled to the second sleeve;
- a first sleeve actuator configured to translate the first sleeve;
- and
- a second sleeve actuator configured to translate the second sleeve, the second sleeve actuator separate from the first sleeve actuator;
- wherein the thrust reverser is configured such that movement of the second sleeve causes movement of the blocker door into and out of the duct,
- wherein the blocker door is configured to be stowed above a skin of the first sleeve when the thrust reverser is stowed, and
- wherein the second sleeve is outside of the duct when the thrust reverser is deployed;
- a first link coupled to the second sleeve;
- a crank coupled to the first link;
- and
- a second link coupled to the crank and to the blocker door.

- wherein the blocker door is configured to be stowed in an internal cavity of the first sleeve when the thrust reverser is stowed;
- and
- wherein the second sleeve is outside of the duct when the thrust reverser is deployed;
- a first link coupled to the second sleeve;
- a crank coupled to the first link;
- and
