Abstract
A metering pin for use in a multi-actor damping system is disclosed herein. The multi-actor damping system may be used in a shock strut assembly to alter a damping curve of the shuck strut assembly. The metering pin may be configured to transition the multi-actor damping system from a first damping actor configuration to a second damping actor configuration. The first damping actor configuration may correspond to a first damping curve. The second damping actor configuration may correspond to a second damping curve. The first damping curve being different than the second damping curve.
Claims17
A metering pin apparatus, comprising:
- an elongated member extending from a first end to a second end, the elongated member defining an axis, the elongated member including a first side, a second side, a third side, and a fourth side, the first side disposed opposite the third side and the second side disposed opposite the fourth side, the elongated member configured to transfer torque about the axis;
- a first flute profile disposed in the first side, the first flute profile comprising a first groove;
- and
- a second flute profile disposed in the second side, the second flute profile comprising a second groove, wherein:
- the first flute profile extends a first length along the elongated member,
- the second flute profile extends a second length along the elongated member,
- the first length is greater than the second length,
- the first flute profile is further disposed on the third side, and
- the second flute profile is further disposed on the fourth side.
A multi-actor damping system, comprising:
- a main orifice plate;
- a metering pin configured to transfer torque from the metering pin to the main orifice plate, the metering pin configured to translate relative to the main orifice plate, the metering pin configured to transition the multi-actor damping system from a first damping actor configuration including a first damping curve to a second damping actor configuration including a second damping curve, the first damping curve being different from the second damping curve;
- and
- a flow restrictor coupled to the main orifice plate, the flow restrictor configured to contact the metering pin in the first damping actor configuration, the flow restrictor configured to be separated from the metering pin in the second damping actor configuration.
A shock strut assembly, comprising:
- a strut cylinder including a primary chamber;
- a strut piston, the strut cylinder configured to receive the strut piston;
- an orifice support tube positioned within the primary chamber of the strut cylinder;
- a main orifice assembly disposed within the orifice support tube, the main orifice assembly including a main orifice plate;
- a metering pin positioned within the primary chamber, the metering pin defining an axis, the metering pin configured to translate with the strut piston, the metering pin configured to rotate about the axis and transition the shock strut assembly from a first damping actor configuration to a second damping actor configuration;
- and
- a flow restrictor coupled to the main orifice plate, the flow restrictor configured to contact the metering pin in the first damping actor configuration, the flow restrictor configured to be separated from the metering pin in the second damping actor configuration.
