Title:
【発明の名称】層流制御翼
Document Type and Number:
Japanese Patent JP3012864
Kind Code:
B2
Abstract:
A laminar flow control aircraft wing combines suction surfaces and slots in its leading (18) and trailing edge (22) regions, with natural laminar flow over its main box (20) region to achieve laminar boundary layer flow over a majority of the wing surface area. The wing includes a leading edge flap that is used to protect the leading edge region of the wing from insect accumulation and surface erosion caused by the impact of dirt, rain, or other airborne materials when the leading edge flap is deployed in a low-speed position. At high aircraft speeds, the leading edge flap is stored in the surface of the leading edge region of the wing and forms part of the suction system for that area of the wing. The wing also includes a flexible trailing edge suction surface spoiler system that allows the spoilers to bend either upwardly for lateral control or downwardly when the trailing edge flap is deployed into a low-speed position.
