Andrew Marion, a junior at Kennesaw State University’s Southern Polytechnic College of Engineering and Engineering Technology, is using computer simulations to study how air moves around high-speed aircraft wings. His research focuses on the aerodynamic behavior of specialized wing shapes at speeds ranging from 250 to 760 miles per hour.
Marion’s work centers on delta wings, which are triangular and commonly found on fighter jets. He specifically examines compound delta wings, a design that combines multiple triangular sections to improve efficiency at both low and high speeds. These designs generate swirling airflow patterns that are complex to analyze but can enhance performance.
By using computational fluid dynamics (CFD), Marion is able to simulate airflow over various wing configurations without needing to build physical models for each test. This method allows for rapid testing of different designs, adjustment of variables, and identification of promising options before moving on to more costly prototypes or experiments.
“Simulations let us test a lot of configurations rapidly and see information that’s hard to find in experiments,” Marion said.
His research aims to address safety and efficiency challenges as planes approach transonic and supersonic speeds. At these velocities, shock waves form along the wings, increasing air resistance and making aircraft harder to control. The data produced by Marion’s simulations can help engineers anticipate where problems may arise during flight.
“Andrew exemplifies how undergraduate research enhances the learning experience,” said SPCEET Dean Lawrence Whitman. “He is tackling complex aerospace challenges with creativity and discipline. His work demonstrates how Kennesaw State students can contribute meaningful solutions to real-world engineering problems.”
Marion sees his approach as supporting renewed interest in supersonic passenger travel by potentially reducing fuel consumption and lowering costs associated with development. He also believes it gives engineers more freedom early in the design process because unconventional concepts can be tested without significant financial risk.
Looking forward, Marion plans to attend graduate school and pursue a career in either the aerospace industry or government research labs. For his next project, he will investigate how features inspired by owl feathers could be used on aircraft wings to reduce drag, delay stall, and improve maneuverability during steep climbs.
For students considering similar research paths, Marion advises early involvement in projects that spark genuine interest and encourages taking advantage of mentorship opportunities available at Kennesaw State University.
“I would say just be persistent and pick a project you’re interested in,” he said. “If you’re going to spend time working on it, you want to be invested in it.”
