In this episode of Actually It IS Rocket Science we delve into the fascinating world of rocket cooling and the challenges engineers face in preventing these powerful machines from melting. Our experts, Sean Bowman and Daniel Garcia, shed light on the innovative methods employed to maintain structural integrity and ensure successful space missions.

Rocket engines generate temperatures equivalent to the surface of the sun, presenting a daunting task: how to keep everything from melting? One approach, known as blade cooling, involves designing components to melt in a controlled manner. Another method, film cooling, utilizes liquid fuel to create a protective layer between the exhaust gases and the nozzle walls. In fact, the iconic black streak observed during the launch of the Saturn 5 was a result of film cooling.

However, at Vaya, the team has developed a groundbreaking solution called the regeneratively cooled nozzle. This design involves circulating a coolant fluid through the walls of the nozzle, not only keeping it cool but also harnessing the resulting energy to power other rocket systems. This nozzle operates in an environment of extreme temperature gradients, with cryogenic fluid on one side and scorching hot exhaust gases on the other.

The analysis and simulation conducted by experts like Daniel allow for iterative design improvements, reducing the need for costly physical testing. By carefully studying the behavior of cooling channels, they ensure efficient heat extraction while minimizing pressure drop. This balance is crucial to maintain optimal energy levels and facilitate the injection of the remaining fluid into the combustion chamber.

Interestingly, the high friction and intense heating experienced during reentry into the atmosphere are mitigated during ascent. Launch vehicles gain significant velocity, surpassing the speed of sound and entering supersonic regimes. As they ascend, the lower density of particles in the upper atmosphere reduces the impact of frictional heating. On the other hand, reentry subjects rockets to extreme friction and intense heating due to the dense atmosphere encountered at lower altitudes.

Understanding the complex physics of shocks and supersonic regimes is paramount in designing rockets that can withstand the challenging ascent and reentry phases. By integrating appropriate materials and accounting for the heating effects, engineers ensure the success of space missions.

Rocket science continues to push the boundaries of human knowledge and engineering prowess. The ability to cool rocket components under such extreme conditions is a testament to the remarkable advancements in technology and the ingenuity of the experts at Vaya Space. As we explore the mysteries of the universe, we can rest assured that their innovative solutions will keep us soaring to new heights.

Space is more than just a billionaire’s race: it’s a domain of exploration fostering technological innovation in the commercial space industry. Today, there are over 10,000 space-focused start-ups in the world all striving to break through with different technologies, visions, and goals. What sets some apart from others, however, are the unique partnerships and innovative technological designs aimed at taking space propulsion to the next level - literally.

In this episode of The Vaya Space Podcast, host Michelle Dawn Mooney, speaks with guests Rob Fabian, Chief Operations Officer (COO) of Vaya Space, and Valentine Moroz, COO of SoftinWay Inc. about the challenges facing New Space Propulsion, as well as viewpoints, and strategies on the future of the technology.

The three discuss:

1) How leasing software from SoftinWay has grown into a new, innovative partnership within the field

2) Everything you should know about propulsion in today’s landscape

3) Exciting new technologies were created during the development of the project

Fabian explained, “I think a lot of what we’re seeing in the industry today, certainly what we’re seeing at Vaya Space, is an outgrowth in new technologies that have come out to support the underlying process…we’re doing additive manufacture of turbo pumps, of injectors, of our fuel grains themselves, it’s an integral part to how our vortex hybrid engine works but that speed of design…I think it’s a game changer for the entire industry not just for Vaya Space.”

On the challenges facing the industry, Moroz remarked, “I see other challenges, the challenges, in my opinion, are two, maybe three types of challenges, two technological and the third one is not. First of all, you know, seeing [the] success of companies like Blue Origin and SpaceX, feels like a lot of young engineers just assume that it’s really easy and you can just reprint everything and it will work, but that’s not the reality.”

Fabian has been in the air and space industry for over thirty years, first starting his career in the United States Air Force before retiring at the Colonel level in 2013. He worked for BAE Systems as a program manager, then held several senior leadership positions at Rocket Crafters, Inc. In addition to his role as COO at Vaya, Fabian serves as an Executive Board Member for the Space Coast Consortium Apprenticeship Program. He’s a proud graduate of the U.S. Air Force Academy, with a Bachelor’s in Space Operations, and holds his MPA from the University of Oklahoma, as well as a Master of Arts in National Security and Strategic Studies from the U.S. Naval War College.

Moroz earned his B.S. in Business Management with a focus on entrepreneurship, computational finance, and quantitative analysis from Babson College. Moroz has over eighteen years of experience in engineering and risk management. He began his career in analytics and macro research with notable work as a risk Analyst for K2 Advisors. Afterward, Moroz founded Bluefront Capital, LLC. Today, Moroz is currently the COO of SoftinWay and a specialist in Turbomachinery Technologies.
