SAN FRANCISCO, Calif. – June 25, 2013 – Lam Aviation, Inc., today announced that it has successfully flown a Lancair Columbia (now Cessna Corvalis) airframe retrofitted with a new wing equipped with a simple version of the Lam Aileron™. Flight test and evaluation show that the modified aircraft realizes improved performance by every measure when compared to the production Corvalis, the current best performer in its class. The modified airplane has received Federal Aviation Administration (FAA) approval for further expansion of flight test and demonstration, including a flight from Bend, Ore., to Oshkosh AirVenture 2013. Lam Aviation has raised a second round of venture funding, as the company expands the breakthrough technology for broader use.
The Lam Aileron represents an important innovation in aviation technology. The Lam Aileron, invented by career aerospace engineer, designer and builder Lawrence Lam, is the first major change in aileron design since ailerons were first implemented on airplanes a century ago. The current Corvalis demonstrator was designed and built by renowned aerospace engineer Greg Cole of Windward Performance in Bend, Ore. The Lam Aileron offers pilots and manufacturers clear improvements in all metrics of fuel efficiency, cruise performance, range, overall safety and flight-handling characteristics – among other key benefits – without compromising any parameter of performance or quality.
Flight test results of the Lam Columbia (Corvalis) have demonstrated dramatic improvements in fuel economy, cruise performance, rate of climb and flight handling, including roll rate, roll authority at slow speeds and stall speed. The modified aircraft also has an increased useful load and range.
Key test results of the airplane equipped with Lam Aileron include:
- Improved Cruise Performance – at equivalent power settings, the modified airplane cruises 12-16 knots faster.
- Decreased Fuel Consumption – at equivalent airspeeds, the modified airplane consumes 20-30 percent less fuel with corresponding increases in range.
- Increased Rate of Climb – 40-50 percent greater rate of climb after modification.
- Increased Useful Load – aircraft useful load increased by 200 pounds.
- Improved Flight-Handling Characteristics – roll rate is increased and stick forces decreased. Roll authority and flight-handling characteristics are improved in slow flight.
Commented test pilot Len Fox, a former naval aviator and US Navy test pilot: "From the pilot's perspective, operation of the Lam Aileron is seamless. With the Lam Aileron, a slower stall speed was achieved with a smaller wing. The reduction in wing area contributed to a higher cruise speed. It was determined that the horizontal tail required to provide optimum stability will also be smaller, resulting in yet faster cruise speeds."
Greg Cole, renowned aerospace engineer: "The Lam wing is now a proven comprehensive solution for improved aircraft performance. It couples the functions of high-speed ailerons with powerful, low-speed lateral control, while improving the maximum lift coefficient of the wing. The Lam Aileron may also offer improved low-speed stall departure resistance. This system has application in small General Aviation aircraft and STOL bush planes, as well as larger aircrafts such as business jets and even large transport category aircraft.”
