Abstract
A variable camber wing for mounting to a vehicle chassis has an actuator shaft and a static pin extending from the chassis. The wing's nose segment defines a proximal edge and a distal edge and has a channel therethrough between the proximal and distal edges, an arcuate aperture therethrough aft of the channel, and a second aperture therethrough aft of the arcuate aperture. The wing has a first linkage defining a clevis on a proximal end and hingeably connected to the nose segment. The clevis can rotatably engage with the static pin extending through the arcuate aperture. A second linkage defines a second clevis on a proximal end and a distal edge. The second linkage is configured to hingeably connect to the first linkage.
Claims11
A variable camber wing for mounting to a vehicle chassis comprising:
- an actuator shaft extending from the vehicle chassis and capable of angular rotation about an axis of said actuator shaft;
- a static pin affixed to the vehicle chassis;
- a nose segment defining a proximal leading edge and a distal edge, having a channel therethrough between said proximal leading edge and said distal edge, an arcuate aperture therethrough aft of said channel, and a second aperture therethrough aft of said arcuate aperture, and said nose segment having a head formed at said distal edge, said actuator shaft being affixed in said channel to rotate said nose segment;
- a first linkage defining a clevis on a proximal end, a distal end aft of said proximal end, said first linkage configured to hingeably connect to said nose segment, wherein said clevis is complementarily configured to rotatably engage with said static pin extending through said arcuate aperture;
- and
- a second linkage defining a second clevis on a proximal end and a trailing distal edge, the second linkage configured to hingeably connect to said first linkage, wherein said second clevis is complementarily configured to rotatably engage with said head of said nose segment.
