Flow channels

A method of reducing vibration and/or buffet of an aerospace vehicle having a body on a wing, the method comprising

• providing at least one flow channel attachable to the body, the flow channel comprising a channel length having a first portion parallel to a maximum waterline thickness location of the body and at least a second portion non-parallel to the maximum waterline thickness location of the body;
• a leading edge at a first end of the channel length, the leading edge separated from a trailing edge by a continuous free edge along the channel length, the free edge projecting a predetermined height from an attaching edge attachable to at least a portion of a surface of the body;
• modifying resultant vortices formed at air speeds between about 0.2 to about 0.9 mach;
• and
• reducing or minimizing shock formations or separation regions of the freestream in proximity to the body and/or body attachment and wing.

An aerospace vehicle comprising:

• a wing;
• a body coupled to the wing;
• and
• a flow channel coupled to the body, the flow channel comprising:
• a channel length having a first portion essentially parallel to a maximum waterline thickness location of the body and at least a second portion non-parallel to the maximum waterline thickness location of the body;
• a leading edge at a first end of the channel length, the leading edge separated from a trailing edge by a continuous free edge along the channel length, the free edge projecting a predetermined height from an attaching edge attachable to at least a portion of a surface of the body.
