ABSTRACT:
An airplane arresting gear has a generally planar frame (20) having a front end and a rear end that is adapted to be attached at the front end to a structure of the airplane for pivotal movement about a frame pivot axis (FPA) substantially parallel to the airplane z-axis between a stowed position in which the frame (20) resides within the fuselage skin and a deployed position in which the frame (20) extends rearwardly and obliquely downwardly with respect to the x-axis of the airplane. A shank (30) having a cable hook (80) at the rear end is coupled at its front end to the rear end of the frame (20) for pivotal movement about a shank pivot axis between a deployed position in which the shank (30) extends rearwardly from the shank pivot axis and a stowed position in which the shank (30) extends generally forwardly from the shank pivot axis and lies abreast of the frame (20). A deploying damper-actuator (70), which is coupled between the frame (20) and the structure of the airplane moves the frame (20) from the stowed position to the deployed position. A retractor actuator (92), which is likewise coupled between the frame (20) and the structure of the airplane, moves the frame (20) from the deployed position to the stowed position. An actuator mechanism (74), which is connected between the frame (20) and the shank (30), moves the shank (30) between the deployed and stowed positions. An up-swing damper (52) prevents the frame/shank unit (10) from contacting the fuselage.
