Clemson researchers redesigned and modified a mobile drill press to retrofit a section of a runway that halts overrun aircraft, ultimately minimizing aircraft damage and passenger injury. The process of retrofitting the end of a runway at Greenville Downtown Airport required more than 80,000 holes to be drilled in the concrete. Pace Pavement Technologies recognized that manually drilling the holes was not an option and there needed to be a more efficient and accurate way to drill.
"We visited several machine shops and pneumatic suppliers and received minimal assistance in the design and build of a mobile drill press," said Carl Pace, president of Pace Pavement Technologies Inc. "Clemson University stepped up to the challenge and enjoyed taking on this project."
Seven Clemson University student researchers and their faculty adviser met with representatives from Pace Pavement Technologies Inc. to discuss the design problems and challenges related to their mobile drill press.
"We needed to reduce the weight of the machine by half so as to not cause any damage to the pavement underneath," Pace said.
The students began by redesigning the undercarriage and modifying the wheels to evenly spread the weight of the machine and reduce ground pressure.
"Clemson University student researchers truly went above and beyond their call of duty by not only reducing the ground pressure of the mobile drill press, but also improving the machine's overall performance and maneuverability," said Gregory Mocko, an assistant professor in Clemson's mechanical engineering department.
The students improved the overall performance of the machine by altering the plumbing, developing a gauge to adjust each drill simultaneously and adding a device that allows the operator to better control drill depth. They also published an operations and parts manual.
"I was overjoyed to have young minds really focused on this project," said Pace. "They gave this project the attention that it deserved and I truly hope we have the opportunity to work with Clemson again."
Mechanical engineering researchers Gregory Mocko, Mark Connelly, Curtis Duckett, Brock Fitschen, Shane Reid, Samuel Smith III, Chris West and Austin Wise completed the mobile drill press project.

EU should scrap airline emissions tax: IATA
New Delhi (AFP) July 25, 2012
The European Union should scrap a controversial carbon tax on air travel and seek a global solution to the emissions problem, the global aviation industry's chief said on Wednesday. The EU imposed the Emissions Trading Scheme (ETS) on January 1, but over two dozen countries, including India, Russia, China and the United States, have opposed the move, saying it violates international law. ... read more
