Military plane MC-130J trials wing 'finlets' to diminish air resistance and fuel expenses
The United States Air Force is exploring innovative ways to modernize its fleet, reduce costs, and increase combat capabilities. One such initiative involves the addition of small aerodynamic elements to aircraft, such as finlets, winglets, and microvanes.
Deputy Assistant Secretary of the Air Force for Operational Energy, Safety, and Occupational Health, Roberto Guerrero, has highlighted drag reduction initiatives like finlets as a tangible way to modernize the fleet. According to Guerrero, every gallon of fuel saved by these initiatives extends operational reach and enhances readiness in contested logistics environments.
The Air Force has recently taken a significant step forward in this endeavour, with the MC-130J special operations aircraft taking off from Eglin Air Force Base, Florida, sporting tiny aluminium fins, known as finlets. These finlets are intended for installation on the entire C-130J fleet, which includes Super Hercules cargo aircraft, AC-130J gunships, HC-130J helicopter refuelers, and WC-130J "weatherbirds."
The finlets are designed to reduce drag on the Air Force's C-130 aircraft by 6 to 8 percent. This reduction could potentially increase the C-130's range and fuel efficiency. The addition of finlets to C-130s has been a collaborative effort, supported by several organizations, including the 96th Test Wing, Air Force Operational Energy Office, Air Force Special Operations Command, Special Operations Forces/Personnel Recovery Program Office, Air Force Research Laboratory, Defense Innovation Unit, and contractor Vortex Control Technologies.
Flight testing of the MC-130J with finlets began on July 16. After the flight testing is complete, the MC-130J will go to Edwards Air Force Base, California, for further testing that includes airdrops.
The Air Force has also been evaluating microvanes on the C-17, inching closer to deploying them fleetwide after more than two years of testing. However, the exact test dates for both winglets on KC-135 and microvanes on C-17 are not clearly established in the available information.
The Air Force's announcement of the finlets milestone was made on a day that Roberto Guerrero described as "an exciting day for the Department of the Air Force." These initiatives are part of the Air Force's ongoing efforts to improve fuel efficiency, reduce costs, and enhance the capabilities of its aircraft fleet.
