Methods and apparatus to control movement of a component


Methods and apparatus to control movement of a component are disclosed herein. An example apparatus includes a housing defining a bore and a piston disposed inside the bore. The piston is to be coupled to a movable component disposed outside of the bore. The example apparatus further includes a fluid flowline in fluid communication with a first chamber of the bore and a second chamber of the bore. The first chamber is on a first side of the piston, and the second chamber on a second side of the piston. The example apparatus also includes a valve to control fluid flow through the fluid flowline. The valve is to be in a first state to enable the piston to dampen movement of the component, and the valve is to be in a second state to enable the piston to hold the component substantially stationary.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This disclosure was made with Government support under Contract No. OTA DFTAWA-10-C-00030 awarded by the Federal Aviation Administration. The Government of the United States may have certain rights in this disclosure.

FIELD

The present disclosure relates generally to movable components and, more particularly, to methods and apparatus to control movement of a component.

BACKGROUND

Generally, an aircraft includes flaps to adjust aerodynamics of the aircraft. A position of a flap may be adjusted by an actuator coupled to the flap. During flight, the flap is subjected to a variety of loads from the actuator and passing air.

SUMMARY

An example apparatus includes a housing defining a bore and a piston disposed inside the bore. The piston is to be coupled to a movable component disposed outside of the bore. The example apparatus further includes a fluid flowline in fluid communication with a first chamber of the bore and a second chamber of the bore. The first chamber is on a first side of the piston, and the second chamber on a second side of the piston. The example apparatus also includes a valve to control fluid flow through the fluid flowline. The valve is to be in a first state to enable the piston to dampen movement of the component, and the valve is to be in a second state to enable the piston to hold the component substantially stationary.

Another example apparatus includes a housing and a piston disposed in a bore defined by the housing. A first side of the piston defines a first end of a fluid flow path, and a second side of the piston defines a second end of the fluid flow path. The piston is to be coupled to a movable component disposed outside of the bore. The example apparatus further includes a valve disposed along the fluid flow path. The valve is to be in a first state to enable the piston to be driven along the bore by the component, and the valve is to be in a second state to prevent the piston from being driven along the bore by the component.

Another example apparatus includes a hydraulic piston assembly including a housing defining a bore. The example apparatus further includes a dual-acting piston disposed in the bore. The piston is to be coupled to a movable component disposed outside of the bore such that movement of the component is to drive the piston along the bore. The example apparatus also includes a valve to control fluid employed via the hydraulic piston assembly. The valve is to be in a first state to enable to the piston to displace the fluid, and the valve is to be in a second state to lock the piston in place.

The features, functions and advantages that have been discussed can be achieved independently in various examples or may be combined in yet other examples further details of which can be seen with reference to the following description and drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic of an example apparatus disclosed herein coupled to a movable component.
