[Student Highlights] Meet Riley Cox-Gross, Part 2

Coming to the EFRC

Before joining the Eagle Flight Research Center (EFRC), Riley resided near the final approach end of Daytona Beach International Airport (KDAB), where he always found himself intrigued by the aircraft flying overhead.

One day, Riley spotted an unusual aircraft, distinct from the typical Cessna 172s frequenting KDAB. This experimental-looking aircraft featured large side force generators positioned midway along the wings and emitted a powerful roar from its engine. Curious, Riley ventured to the airport to get a closer look. Recognizing the experimental nature of the aircraft, he surmised that it must be associated with EFRC – a deduction that proved correct. Through his exploration of the venerable Ryan Navion, utilized as a research platform for various flight control experiments, Riley left a lasting impression on the EFRC's newest project manager, Patric Hruswicki, who promptly extended an offer for Riley to join the team.

Upon starting at EFRC, Riley engaged in diverse projects, eventually assuming significant roles in endeavors such as the FAA-sponsored UAM control research (PAVER project) and the electrification of the HK-36 Super Dimona Motor Glider, named the e-Spirit of St. Louis.

One of Riley's recent undertakings involved an analysis and optimization project for coaxial rotors. Serving as the project lead, he conducted over 126 tests on a large scale eVTOL coaxial rotor test stand, successfully validating empirical results against theoretical models. While the bulk of the project's work has been completed in recent months, Riley envisions further potential for system enhancement, intending to integrate the project's insights into aspects of his master's thesis.

Though testing has concluded, Riley remains enthusiastic about the project's possibilities and is eager to expand its scope. His energy and dedication have proven instrumental in advancing many of EFRC's initiatives.

Internship Hattrick

If you're a college student, you'll likely agree that snagging just one internship can be quite the challenge. Yet, here's Riley, managing to secure three internships during his undergraduate years, delving deep into the realms of aviation and aerospace engineering.

His internship journey began at Scaled Composites, where Riley stood out as the sole intern among over 400 applicants for the Summer of 2021. This opportunity thrust upon him a remarkable level of responsibility, with the task of constructing a sizable composite UAV from scratch. This experience solidified his passion for engineering. Reflecting on his time at Scaled Composites, Riley reminisces, "The responsibility Scaled placed on me helped to build my confidence in my own abilities and has provided a strong foundation for my aerospace and test pilot career aspirations."

Next was NASA, a dream destination for every aspiring aerospace engineer in the US. Assigned to the PAVER project at the EFRC, Riley joined the rotorcraft aeromechanics branch, a field akin to his previous endeavors. Unlike his previous internship, this one boasted a sizable pool of interns, providing a different yet equally enjoyable experience. He had the chance to contribute to various projects, including the Mars science helicopter and the vertical motion flight simulator.

The adventure ascended to new heights with an internship at Hermeus Corporation, a private entity testing hypersonic aircraft for the Air Force and the Department of Defense. Riley delved into the world of high-speed flight and propulsion, working on engine components and gaining invaluable insights into fast jets. "I was drawn to the realm of fast jets," he explains. "I have a fondness for propulsion and power."

The lessons learned and experiences gained from these adventures have left an indelible mark on Riley, shaping his career aspirations and fueling his passion for aviation and aerospace.

Tips from Riley!

1. Understanding the job you're applying for is crucial, but equally important is knowing the person you'll be working under, as they typically make the final hiring decisions. If they have a passion for airplanes, it's wise to showcase your own enthusiasm for aviation as well.
2. Your project experience is invaluable, and your ability to turn ideas into reality is even more crucial. This could range from group class assignments to personal projects, however active involvement in extracurricular activities will set you apart from others. For instance, Riley's participation in Embry-Riddle's Design Build Fly (DBF) club and NASA Micro-g NExT program equipped him with the skills and expertise to secure multiple internships.
