From requirement analysis to risk assessment to addressing engineering challenges, it is during this research phase where much of the real learning occurs. Here in Part 3 of a five-part series, Dr. John Granier, chief engineer of munitions and energetics at Element, and Dr. Michelle Pantoya, J.W. Wright Regents Chair in mechanical engineering and professor at Texas Tech, talk about these issues as well as about prototyping solutions for the defense industry, highlighting for Machine Design the critical phases that define successful project outcomes.
Granier explains that the process of analyzing requirements typically begins with a thorough examination of what problems need solving. He says that iterative feedback is a vital step. Pantoya points out that one of the challenges in this process is refining and improving the design process before reaching the prototype stage. Time constraints often affect project timelines as well.
Pantoya says there is an increasing reliance on additive manufacturing within academic laboratories, noting its role in developing customized components that may not be available off-the-shelf. AM accelerates the iterative process, enabling rapid prototyping and modifications. She says that mechanical engineers are now better equipped to design and fabricate solutions quickly, offering speed and flexibility to experimental designs.
