ABSTRACT:
Segmented spoilers are parallel arrays of individually-extended barrier surfaces, such as rotatable eccentrically-mounted disks. The overlapping surface areas extend through a slot on a aircraft surface. When actuated, a segmented array generates a stiff, extendable, profiled spoiler-barrier. The individual surface areas are power-activated from below the airfoil surface according to motor commands from autopilots, operators, sensors and computers. Disk spoiler systems provide very rapid generation and retreat of controllable height barriers. The management of Bernoulli lift phenomenon with disk spoilers has unique use on an aircraft's nose, along the top of its wings, on the forward surfaces of horizontal and vertical stabilizers and within the intake sections of gas turbine aircraft engines. Disks are rotated by electric rotor-positioning motors and aircraft-powered axial force systems.
