A spoiler on an aircraft is used to increase drag and reduce lift.[1] Differential spoilers can be used for roll control as well as to reduce the aerodynamic twisting on long, slender, wings.[1] For business jets, the ailerons are ineffective at high cruise speeds and therefore differential spoilers are used for effective roll control.[1]
[[P-61 Black Widow]] – used plug-slot spoilers to lower control forces.[^1]
[[XF10F-1 Jaguar]] – perforated paddle spoilers
[[Have Blue]] – used spoilers on upper and lower wing surfaces
Tornado GR4 – uses spoilers instead of ailerons
[[C-17 Flight Control System]] – 8 spoilers
[[C-17 Roll Control Law]] – spoilers are primarily used for a roll command
B-1 Roll Control Channel – uses spoilers
[[F-14 Spoiler Actuator Model]]
[[F-4 Phantom Flight Control System]] – uses spoilers for lateral control
[[F-14 Lateral Control System]] – shows the stick gradient for the spoilers
[[B-52 Flight Control System]] – uses spoilers
[[X-47B]] – used spoilers on the upper surface of the wing
[[X-47A Pegasus UCAV]] – also used inlaid spoilers on the upper surface of the aircraft
[[Tornado Aerodynamics]] – spoilers are used at low speed for roll control
