For more than three decades, Hill Air Force Base in Utah has stripped paint off fighter aircraft with abrasive-blasting equipment from Clemco Industries (Washington, Missouri, USA).
Last year, the base’s 576th Aircraft Maintenance Squadron modified an existing Clemco blasting facility with new-generation robotic technology. The facility now strips paint off the A-10 Thunderbolt II, nicknamed the “Warthog.”
The new paint-removal process is accomplished by two robots, each with four hose attachments that move independently along both sides of the aircraft. With the change, the time to strip an A-10 has decreased from three days to 12 hours or less.
The A-10s require regular exterior maintenance to protect their metal surfaces from corrosion due to moisture and the harsh environments in which they continually operate.
“There are going to be across-the-board improvements, including a dramatic reduction in exposure to a hexavalent-chromium dust environment. This is perhaps the greatest benefit to the robotic system,” says Tim Randolph, director for the 576th Aircraft Maintenance Squadron. “Savings will also be seen with reduced operating time and less power consumption, as well as reduced costs in material. We really haven’t found a downside to this system.”
Clemco describes itself as the world’s largest manufacturer of air-powered abrasive blast equipment used to clean, deburr, shot peen, remove coatings, finish, or otherwise improve surfaces being blasted. Since the mid-1940s, Clemco has built industrial-grade blast equipment for contractors, facility owners, metal fabricators, and manufacturers, along with offering safety and protection accessories.
