Abstract
A shock strut is disclosed herein. The shock strut includes a shock strut cylinder, a shock strut piston slidably disposed within the shock strut cylinder, a rebound chamber disposed within the shock strut cylinder and adjacent the shock strut piston, a first percolation seal configured to restrict a first flow of fluid between the shock strut cylinder and the rebound chamber, and a second percolation seal configured to restrict a second flow of fluid between the shock strut cylinder and the shock strut piston.
Claims20
A shock strut, comprising:
- a shock strut cylinder;
- a shock strut piston slidably disposed within the shock strut cylinder;
- a rebound chamber disposed within the shock strut cylinder and adjacent the shock strut piston;
- a first percolation seal configured to restrict a first flow of fluid between the shock strut cylinder and the rebound chamber;
- and
- a second percolation seal configured to restrict a second flow of fluid between the shock strut cylinder and the shock strut piston.
A landing gear system, comprising:
- a fluid source;
- a conduit;
- and
- a shock strut coupled to the fluid source by the conduit, the shock strut including:
- a shock strut cylinder;
- a shock strut piston slidably disposed within the shock strut cylinder;
- a rebound chamber disposed within the shock strut cylinder and adjacent the shock strut piston;
- a first percolation seal configured to restrict a first flow of fluid between the shock strut cylinder and the rebound chamber;
- and
- a second percolation seal configured to restrict a second flow of fluid between the shock strut cylinder and the shock strut piston.
A method of restricting percolation within a landing gear assembly, comprising:
- sensing whether the landing gear assembly is being retracted or extended;
- inflating a first percolation seal in response to the landing gear assembly being retracted;
- inflating a second percolation seal in response to the landing gear assembly being retracted;
- deflating the first percolation seal in response to the landing gear assembly being extended;
- and
- deflating the second percolation seal in response to the landing gear assembly being extended.
