Lam Aero System

Aileron & Flap Innovation: The Lam Aero System

Lam’s patented aileron technology delivers new safety and performance by uncoupling the sizing relationship between flaps and ailerons. The Lam Aero System (LAS) creates new flexibility for flight wing control design.  It permits ailerons and flaps to be of any span, including full span.  Separate flight control functions can be mixed for additional modes of operation, such as speed brakes, etc.  It also has proven anti-spin capabilities.

Renowned aerospace engineer, designer and builder, Greg Cole of Windward Performance, has leveraged the Lam Aero System capabilities to retrofit a Lancair Columbia 300 airframe with a new smaller wing and tail made possible by the high-lift of the Lam Aero System. Following rigorous flight tests and evaluation in Bend, Oregon by highly regarded GA test pilot, former Naval aviator and US Navy test pilot Len Fox, the system has exceeded all expectations.  More importantly, it provides strong envelope protection.

The Lam Aero System based on our patented aileron technology

Lam’s patented aileron creates two panels: one on top of the other at the trailing edge of the wing.  The upper aileron panel is deflected upward only from the neutral position; while the lower, auxiliary flap panel is capable of downward/outward deflections from the neutral position. The upper panel is deployed independently as an aileron and the lower panel is deployed independently as an auxiliary flap. Deflecting the Lam Aileron upward on one side only provides a rolling moment. Upward deflection only for roll control makes the entire trailing edge available for downwardly deflected surfaces such as flaps. This new aileron design releases flaps and ailerons from their traditional size interdependence on the trailing edge and eliminates the compromises between slow flight capability and roll control authority that follow while improving flight handling characteristics. It also allows the usual separate functions of flaps and ailerons to be mixed for additional operations such as speed brakes or drag rudders.
