USAF tests fuel-saving winglets on MC-130J Commando II aircraft
 
The USAF 413th Flight Test Squadron, based at Eglin AFB, Florida, recently started flight of C-130 Hercules military airlifter fitted with "fuel-saving" winglets, the USAF announced on April 19, 2016. Lockheed Martin originally lead the program, but abandoned it three years ago.

The test aircraft was fitted with vertical fins on each wing, called winglets. The 413th Flight Test Squadron aircrew and engineers tested the modified aircraft over eight flights.

The goal of the tests was to collect data on possible fuel efficiency improvements and performance with the winglets and lift distribution control system installed.

The USAF didn't disclosed results of this first experimental flights.

Wingtip devices increase the lift generated at the wingtip and reduce the lift-induced drag caused by wingtip vortices, improving lift-to-drag ratio. This increases fuel efficiency in powered aircraft and increases cross-country speed in gliders, in both cases increasing range.
