Lockheed Martin is testing winglets and other drag-reducing modifications to cut the fuel consumption of C-130 Hercules and C-5 Galaxy airlifters.
With large-scale wind tunnel testing completed, Lockheed is fabricating a shipset of winglets for flight testing on a C-130 in 2012. The modification could be available for both retrofit and forward-fit by early 2014.
Computational analysis and small-scale tunnel tests have been completed on the C-5 winglets. Large-scale tunnel tests are planned for 2012, leading to flight tests in 2014 “if the customer is interested,” says Jack O’Banion, director of advanced development programs at Lockheed’s Marietta, Ga., plant.
The 5-ft.-tall winglets are projected to reduce cruise fuel flow by 170 lb./hr. on the C-130J and “probably more” on older versions of the Hercules, he says. They are designed to be fitted to any C-130 with the beefed-up “enhanced service life” center wingbox. This has the extra structural margin to accommodate winglet-induced bending loads.
Winglets for the C-5M are 6 ft. tall and projected to reduce cruise fuel flow by 1,100 lb./hr. This is on top of the 8-20% improvement in fuel efficiency that comes with re-engining of the C-5 with General Electric CF6-80C2 high-bypass turbofans, O’Banion says, adding that the wing already has sufficient margin to accommodate the winglet loads.
Lockheed Martin in August flight tested an aft-body drag-reduction modification on the C-130. This comprises a series of 36 vortex generators mounted on the aft fuselage. These “microvanes” alter the aft-body flowfield to pull the underbody vortex closer in and reduce base drag, he says.
Results are still being analyzed, but indications are the microvanes will reduce total drag by up to 3.7%, O’Banion says, for a fuel-consumption reduction of 2-3%. No significant changes in aircraft handling have been observed, he says.
The vortex generators, mounted in rows on the aft fuselage on either side of the rear loading ramp, are planned to be available by the end of 2012 for forward-fit and retrofit to the C-130J and earlier Hercules.
Another fuel-saving modification being studied for older C-130s is an upgrade to the latest Series 3.5 version of Rolls-Royce’s T56 turboprop, coupled with Hamilton Sundstrand’s NP2000 eight-blade propeller.
For the C-5, Lockheed also is working on a drag cleanup that is expected to improve fuel efficiency by 2-3%. This would include new seals on the flight controls to minimize aerodynamic leaks that cause drag; and new seals in the pressurization system to reduce bleed-air demand on the engines and thus improve their fuel efficiency.
In addition, equipment installed on the C-5s over time — such as defensive systems — would be cleaned up to reduce parasitic drag. “We are in the process of laying out a detailed program for the Air Force, including the business case and potential benefits,” O’Banion says.
The C-130 and C-5 drag reductions are part of an initiative by the U.S. Air Force to cut its fuel consumption. Other elements include drag cleanups on the Boeing C-17 and KC-10 and engine upgrades on the KC-135.

The 451st Expeditionary Logistics Readiness Squadron aerial port flight assisted the C-5 Galaxy’s loadmaster crew in successfully loading an F/A-18 Super Hornet into the Galaxy’s cargo bay on Kandahar Airfield, Afghanistan.
The Hornet experienced malfunctions which caused it to divert and land at Kandahar Airfield while supporting Operation Enduring Freedom last March. Upon landing, the aircraft experienced hot brakes and upon stopping, both brakes were engulfed in flames. The Kandahar, Fire and Rescue extinguished the fire, but the right fuselage was severely damaged.
Charles Miller, the F/A-18 deputy program manager, and a team of four Defense Department civilians have been preparing to recover the aircraft in order to bring it back to the U.S. to Fleet Readiness Center Southwest to perform the necessary repairs since July.
The preparation included coordinating with senior leadership at the Navy’s Commander of Naval Air Forces and the Air Force’s Air Mobility Command in order to obtain the required certification to transport the aircraft back on a C-5 to Naval Air Station North Island in San Diego, Calif.
“Typically, an aircraft would be flown back to the states if the damage was minor,” said Miller. “But this F/A-18 sustained substantial damage which our engineering support team determined to be critical and unflyable.”
The C-5 aircrew was eager for the opportunity.
“We’re willing to help any of our sister services who need it,” said Air Force Maj. Steven Hertenstein, the pilot of the C-5 Galaxy who is deployed from Travis Air Force Base, Calif. “Carrying cargo is what this aircraft was designed to do, and we’re glad to be a part this.”

MARTINSBURG – The 2011 Thunder Over the Blue Ridge airshow and open house will feature what organizers are calling a “once-in-a-lifetime opportunity” to see the United States Air Force’s F-22 Raptor, a new fighter aircraft that features plenty of power and speed.
Although the F-22 won’t be performing, airshow visitors will have the opportunity to see it up close and learn more about its capabilities from the pilots who fly it.
“Last year we brought you the Thunderbirds and this year we’re going to bring you variety and fire. It’s going to be a different show with a very exciting lineup,” Col. Brian Truman said at the July 1 afternoon press conference, where he and others discussed the free two-day event that is co-sponsored by the 167th Airlift Wing, United Way of the Eastern Panhandle and Eastern Regional Airport Authority.
Truman, who is vice commander of the 167th Airlift Wing and president of Thunder Over the Blue Ridge Inc., said a variety of military and civilian aerial acts will be part of this year’s lineup.
One new addition will be the U.S. Navy’s Trojan Horseman, a T-28 warbird aerobatic formation demonstration team, which is slated to fly six vintage World War II aircrafts, he said. The team is slated to perform its choreographed “Salute to the Armed Forces” to patriotic music.
Also appearing will be the Black Daggers, the official U.S. Army Special Operations command parachute demonstration team, as well as the Viper East F-16 Demonstration Team, Truman said.
First Lt. Nate Mueller, a pilot who flies C-5 transport aircraft, predicted the F-22‘s “premier display” will “bring out the aviator in everyone who gets an up-close look.”
“This is a rare opportunity to see the world’s most sophisticated fighter aircraft up close and personal right in our own backyard. It’ something people won’t want to miss,” Mueller said.
He said this stealth aircraft is assigned to the Air Combat Command’s 1st Fighter Wing based at Langley Air Force Base in Virginia.
It has the capacity to cruise at supersonic airspeeds splintering the sound barrier and “boasts being capable of simultaneously conducting air-to-air and air-to-ground combat missions with near impunity,” according to a news release announcing the F-22‘s local appearance.
At some point a jet-powered truck will also “roar down the runway,” Truman said. “And we’re definitely going to blow things up with pyrotecnics. … I can guarantee you it’s going to be exciting.”
Last year’s airshow drew an estimated crowd of about 85,000 over the Labor Day weekend. The event will be held Sept. 17-18 this year when it returns to the Eastern Regional Airport. It will be open 9 a.m. to 4 p.m. both days.
A children’s village will again be featured in one of the base’s 80,000-square-foot hangers and will offer lots of “unique hands-on activities” courtesy of NASA and others, said Sr. Master Sgt. Todd Kirkwood, who is organizing it.
Organization Vice President Nic Diehl agreed this year’s program has some real crowd-pleasers.
“Most of the acts are new. … And we have a better civilian lineup than we’ve ever had before,” Diehl said.
Donations collected at the 2010 show generated more than $100,000 from visitors, and that money was given to the United Way. Admission is free, but a $10 donation benefiting the United Way is encouraged.
United Way officials stressed the importance of funding generated by the airshow and how it helps support their work within the community.
President Tom Jones said the partnerships that made it possible were “over the top” last year. It was a cooperative effort that included 24 volunteer vendors at the show – most of them United Way agencies, he added.
“It’s a community effort and we’re happy to be part of it,” Jones said.
Wing Commander Col. Roger Nye said the community is a driving force behind this show.
“It is a great opportunity for the families to come out here. We’re talking about community. We don’t do this because we are trying to show off anything about ourselves. It’s about giving the community an opportunity to come and see what the men and women in uniform, who live and work right here, do for this nation and give them a chance to enjoy it,” Nye said. “We’re also very proud of how much money was raised last year and being able to give back to the United Way.”
United Way Executive Director Jan Callen said the $100,000 was distributed in a number of ways, including helping fund The Journal’s Warm the Children program, which offers clothing to area children; and the Warming Hands and Hearts program, which offers heating assistance to those in need.
Callen said the $100,000 generated by last year’s airshow was an important part of the approximately $300,000 allocated to about 30 agencies this week.
“The money from the airshow is almost one-third of what the board had the discretion to give out, and that’s a big deal to us,” Callen said.

The US Air Force (USAF) and Lockheed Martin are looking again at the possibility of upgrading older C-5As due to the great demands of the meeting cost and performance targets of the C-5B airlifter’s re-engine program.
Lt. Gen. Tom Owen, commander of Aerospace Systems Command and program executive officer for aircraft procurement and modernization said that “It’s a good idea, but we are in a very fiscally constrained environment.”
“The Defense Department will evaluate the option in future years, if the dollars are available,” said Owen, speaking at the Sept. 30 handover in Marietta, Georgia, of the first production C-5M upgraded under the Reliability Enhancement and Re-engining Program (RERP).
Lockheed Martin says it needs long-lead funding in Fiscal 2014 to avoid a gap in the modification line after the last C-5B is upgraded, and to keep prices agreed upon with major suppliers locked in. These include General Electric for the new CF6-80C engines.
Lorraine Martin, Lockheed Martin vice president for C-5 programs said “As the aircraft proves itself, we are talking to the Air Force about the benefits of a single fleet.” The upgrade extends service life to at least 2040.
The three C-5Ms already in USAF service, the former RERP development aircraft, include a single upgraded C-5A. This is achieving the same performance and reliability as the two modified C-5Bs, according to Lockheed Martin.
Jeffrey Armentrout, business development manager for strategic airlift programs, says that re-engining the C-5 increases thrust by 22%, payload by 27% and range by 20%. Armentrout adds that the mission-capable rate is exceeding the 75% target.
The company has a $6-billion fixed-price production contract to upgrade 49 aircraft, including two C-5Cs, for a total of 52 C-5Ms. The Air Force also operates 59 C-5As, but plans to retire 22 in 2011-12 because of excess strategic airlift capacity.
Congress directed the USAF to study the potential for placing the retired aircraft with the Civil Reserve Air Fleet (CRAF) or international coalition partners. A report will be submitted soon.
USAF C-5 aircraft
Mark Johnston, director of U.S. government air mobility programs, says that Lockheed has approached CRAF carriers, international air forces and foreign airlines informally and believes there is some interest in the excess C-5As. “We will know more in the next 6-12 months,” said Johnston.
Johnston also said that any CRAF airline that took C-5As “would be the first U.S.-flagged outsize-cargo carrier. That’s a unique capability.”
If operators can be found, Lockheed’s interest is in upgrading the retired aircraft with the $4.5 million Avionics Modernization Program (AMP) glass cockpit or $82 million RERP kit, for which AMP is a prerequisite.
Armentrout stated that modernization of the C-5Bs is planned to ramp up to 11 per year at Marietta, but there is excess capacity to upgrade another two aircraft each year for other potential operators.
A Defense Acquisition Board decision on full-rate production is set for Oct. 7. Martin says the program is meeting the “challenging” cost and schedule targets in the contract, with Lockheed seeing “significant” improvements in labor hours on the second and third production C-5Ms.
Upgrading the C-5B/Cs was justified on estimated net cost savings of $9 billion over the life of the program. Owen said, “We have confidence in the numbers used to show the aircraft’s increased capability and enhanced reliability provide a sound fiscal basis for the program,” adding that when it comes to the C-5As, “we will apply a similar method to see if investing more dollars in modernization is the right thing.”

The military already has enough large transport planes and the appropriation of any more in the next budget year will force some into premature retirement, Defense Department officials told a congressional panel last Wednesday.
“We have enough C-17s,” Mike McCord, principal deputy undersecretary of defense (comptroller), said.
Senators Thomas Carper and John McCain said that the C-17, in addition to the C-5, has been critical to airlift in and out of Iraq and Afghanistan.
However, they said, the military’s current fleet of 223 C-17s and 111 C-5s is more than enough airlift capability for years to come. Air Force Maj. Gen. Susan Y. Desjardins, director of strategic plans for Air Mobility Command, and Alan Estevez, principal deputy assistant secretary of defense for logistical and materiel readiness agreed with the leaders’ view.
A department study that concluded in February was consistent with two other studies that found that the current fleet is sufficient “even in the most demanding environments” to take the military through 2016, McCord said. The oldest plane in the transport fleet, Lockheed’s C-5A Galaxy, will be viable until 2025, and the fleet as a whole should last until 2040, he said.
The department has not requested C-17s since the fiscal 2007 budget, yet Congress has added them every year since, spending about $1.25 billion on C-17s that they don’t really need, according to McCord.
The defense secretary has made that case to Congress, and President Barack Obama has promised to veto any legislation that provides for more C-17s.
