GROWING GREATNESS


Brian Cook was majoring in mechanical engineering at Tennessee Technological University. He met his future func- tion chief, Mike Morrison, during a career fair.


“I went up there with Gene Henderson, another Tennessee Tech graduate, and we had a booth. Brian came over to talk with us and then he came back to talk. Tat was impressive,” said Morrison, chief of the Energetic Materials Function.


AMRDEC hired Cook as a co-op stu- dent in 2010. For his senior design project at Tennessee Tech, Cook led a group of


six people whom AMRDEC


asked to develop a method for applying liners to rocket motor cases and improve operations in the lab. Te result of their effort was a machine that has made work more efficient and more effective,


mechanizing a process that previously had been done by hand.


Supporting Cook’s senior design project was Darrell Simonds, a WDI technician who has been working with large and small rocket motors on Redstone Arsenal since 1978.


Simonds’ experience with similar lining systems was instrumental in the team’s success, said Cook.


Cook’s machine gives his WDI team reproducibility for rocket motor demon- strations. Hand-painting the lining into rocket motor cases can result in inconsis- tencies in liner thickness, thus changing the amount of propellant that is loaded into the rocket motor casings and adversely affecting tests, said Morrison.


Simonds added that the new capabil- ity helps tremendously in terms of time saved. “Cook is up to speed now and learning more every day. Tey teach him something and off he goes. He is an asset to the team,” said Simonds.


Cook is now an intern in the Path- ways Program and is working on his master’s degree.


ROCKET WARS Each year, WDI runs a contest called Rocket Wars. Student hires design and build a


boost-sustained rocket motor


within certain parameters for thrust and pressures. Ten they compete against each other as teams. While working, they have fun, but more importantly they get valuable hands-on experience.


Justice Manson, a third-year summer hire majoring in mechanical engineering at the University of Alabama, served as a team leader during the 2010 Rocket Wars com- petition. His teammates included Corey Davis, majoring in aerospace engineer- ing at Purdue University; Drew Johnson, majoring in mechanical engineering at UAH; Jerald Fayorsey, majoring in aero- space engineering at Tuskegee University; and Faith Ryder, majoring in electrical engineering at UAH.


After a briefing from Lilley, the propul- sion technology chief, during which they received guidance and numerics on what to build, Manson and his team got to work.


BRIEFING THE BRASS


One of the first projects that Kristin Spencer, right, undertook after earning her bachelor’s degree in mechanical engineering and going to work in the WDI’s Composite Structures Laboratory was to explore ways of reducing the weight of Army aviation platforms. Here, she briefs her project to reduce the weight of the OH-58 Kiowa Warrior’s M279 Hellfire Missile Launcher to MG James R. Myles, then- commanding general, U.S. Army Aviation and Missile Command (AMCOM); Eric Edwards, AMRDEC director; and CW5 Keith Langewisch, AMCOM Aviation Branch maintenance officer.

“At Propulsion, you see things happen. You do the numbers, you do the drawings and the designs, you do the builds, then you see the results,” said Ryder.


In all of WDI’s mission areas, the goal is to do real, hands-on engineering and science in-house. With the tools,
