摘要： An aerofoil wing comprising upper and lower surfaces meeting at the leading and trailing edges and a camber line representing the curvature of the aerofoil comprising at least two regions of substantially linear increases in curvature and wherein the increases in curvature are of monotonically increasing magnitude. Preferably there are three regions of substantially linear increases in curvature.

摘要： An airfoil having particular use in a general aviation aircraft operating at generally low speeds. The airfoil has a shape designed to produce high lift coefficients at low speeds, with low drag and lower lift coefficients at higher speeds. The airfoil's lift characteristics are not sensitive to surface roughness on the leading edge caused by the accumulation of foreign matter on the airfoil due to the transition to turbulent flow occurring near the leading edge at high lift coefficients.

摘要： Slotted cruise airfoil technology allows production of a substantially unswept wing that achieves the same cruise speed as today's conventional jet airplanes with higher sweep. This technology allows the wing boundary layer to negotiate a strong recovery gradient closer to the wing trailing edge. The result is about a cruise speed of Mach=0.78, but with a straight wing. It also means that for the same lift, the super velocities over the top of the wing can be lower. With very low sweep and this type of cruise pressure distribution, natural laminar flow will be obtained. In addition, heat is transferred from the leading edge of the wing and of the main flap to increase the extent of the natural laminar flow. The slotted cruise wing airfoil allows modularization of the wing and the body for a family of airplanes. The unsweeping of the wing significantly changes the manufacturing processes, reduces manufacturing costs and flow time from detail part fabrication to airplane delivery. The system architecture is all new for cost reduction. A high wing arrangement allows more freedom for installation of higher bypass ratio advanced geared fan engines. A low is wing in conjunction with aft body mounted engines will have a similar effect. Aerodynamic efficiency and engine fuel burn efficiency result in considerable lower emission of noise and greenhouse gases.
