AFRL is laying the groundwork to develop a next-generation tactical tanker concept. This tanker will retain its high-lift characteristics to enable forward basing while producing a very stable wake, which will create an acceptable flow field to refuel a wide variety of air vehicles.
AFRL and Lockheed Martin partnered to complete approximately 200 hours of wind tunnel tests on a next-generation tanker concept model. During 2 weeks of testing at Lockheed Martin's Marietta (Georgia) facilities, engineers collected aerodynamic data to show the effects of placing tanker equipment in various positions on the model. The team analyzed this data to better understand how changing the equipment's position between locations (e.g., on the model's centerline or in a pod on the wingtip) might affect a future tanker's lift and drag, as well as its compatibility with advanced platforms.
In addition, the engineers conducted several tests in which they placed a receiver model in refueling positions behind the tanker. Their test data showed how the tanker-generated aerodynamic flow affected the receiver. Engineers will use this information to evaluate design options for the future tanker concept.
These tests were part of a continuing effort to develop options for the Air Force's next-generation tanker. To develop this highly versatile tanker of the future, AFRL is conducting in-house work in conjunction with Lockheed Martin and Boeing. The team is exploring the combined use of existing technology and unconventional thinking to create a tanker that can refuel a range of aircraft, including fighter aircraft, unmanned air vehicles, and helicopters.
