control surface:

see airfoilairfoil,
surface designed to develop a desired force by reaction with a fluid, especially air, that is flowing across the surface. For example, the fixed wing surfaces of an airplane produce lift, which opposes gravity.

control surface

[kən′trōl ‚sər·fəs]
(aerospace engineering)
Any movable airfoil used to guide or control an aircraft, guided missile, or the like in the air, including the rudder, elevators, ailerons, spoiler flaps, and trim tabs.
In restricted usage, one of the main control surfaces, such as the rudder, an elevator, or an aileron.

control surface

control surface
Aerodynamic surfaces operated from the cockpit controls to control the trajectory of an aircraft. The three primary controls are ailerons, elevators, and rudders. Flaps are secondary control surfaces.

Wing-mounted flaps and slats are another secondary control surface.
The model inertial airframe and control surfaces characteristics and boundary conditions used for simulation should be revised at future work.
That's a huge change, considering that the control surfaces of a conventional, fixed-wing aircraft modify wing areas by no more than about 5 percent, says DARPNs Terry A.
In these ground vibration tests, the F18's hydraulics were powered up, but the control surfaces were inactive.
The 24 3/4-inch pipe, with the port control surface attached, is inserted through the 8-inch guide on the port side of the sled and attached to the port control handle assembly.
The empirical and theoretical methods applied to control surface design are described in depth and their use explained through application to particular cases.

The TLP Pro 1520TG has a bold, clean, high-tech design and features that make it ideal for control applications that require a fully-customisable tabletop touchpanel with a large control surface and multi-source video preview.
Broadwing Air Repair, or BAR, based in Melbourne, Arkansas, is also known for its flight control surface and door repair business.
Here's a short list: Indications that the control surfaces weren't removed for stripping and painting; globs of stripper left in hard-to-reach places and sometimes even painted over; stripper not rinsed from the skin laps; inspection panels cemented in place with paint; wheel bearings shot through with stripper crud because the wheels weren't masked; paint overspray on the windows--especially in a pressurized aircraft; poor masking of stripes and trim; quick turns in curved stripes that indicate sloppy taping and masking; paint sags and missed spots; control surface bearings painted over; overspray in the door jambs, engine spaces and other places that aren't supposed to have paint.
Specific problems include arthritis of wing fold, blade fold and control surface actuation mechanisms; canopy hazing; landing gear strut cracks and leaks; leaking seals for hydraulics and fuel tanks; popped and worn out fasteners; environmental control system inadequacy; and heat-dirt-contamination effects.
Scientists could also control surface tension-and bubble behavior in space-by changing temperatures in a liquid.
