75 tons—plus gravity!

UDRI working to keep landing gear strong on the job

By Pamela Gregg, Communication Administrator, UDRI

The University of Dayton Research Institute has been awarded a $96 million indefinite-delivery, indefinite-quantity Air Force contract to perform engineering services for landing gear systems. Work performed under the 11-year contract will support the Air Force Materiel Command at Hill Air Force Base in Utah. Engineering services will be designed to ensure mission safety; improve system life cycle cost; improve operational capability and performance; improve sustainment, including maintainability and support; and improve environmental safety and friendliness.

UDRI researchers have performed a variety of engineering services, including design, analysis, testing, modeling, prototyping, reverse engineering and failure analysis, for landing gear across multiple Air Force aircraft. In a recent program, researchers built a two-story steel frame equipped with hydraulic actuators to test the nose and main landing gear of a C-130 cargo plane, which has a max take-off weight of 75 tons. The frame had to be large enough to facilitate enough hydraulic force on the landing gear to simulate the gravity forces on a fully loaded C-130 as it hits the runway.

“The landing gear of a cargo aircraft, which frequently cycles through take-offs, landings and taxiing, endure a great deal of stress,” said Mike Bouchard division head for applied mechanics at the Research Institute. “Work we perform provides valuable information that helps our customers better address their needs.”
