Improver Corporation v Remington Consumer Product Limited [1990] F.S.R. 181 is a leading United Kingdom case on patent infringement, particularly in relation to how to establish what specifically a patent covers.
It is a main part of their patent on flying. [1] Unlike modern control surfaces, they used wing warping. [2] In an attempt to circumvent the Wright patent, Glenn Curtiss made hinged control surfaces, the same type of concept first patented some four decades earlier in the United Kingdom. Hinged control surfaces have the advantage of not causing ...
Vortilons are often used to improve low-speed aileron performance, [1] [7] thereby increasing resistance to spin. They can be used as an alternative to wing fences, which also restrict airflow along the span of the wing. [1] Vortilons only stream vortices at high angles of attack [8] and produce less drag at higher speeds than wing fences. [9]

Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).
Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. [1] Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft's drag. Wingtip devices can also improve aircraft handling characteristics and enhance safety for ...
