In Indiana, a group of high school students is playing a pivotal role in NASA’s efforts to create quieter and more fuel-efficient aircraft engines. This initiative is part of a transformative educational collaboration that brings together NASA’s Glenn Research Center, located in Cleveland, Ohio, and the University of Notre Dame’s Turbomachinery Laboratory. The primary aim of this collaboration is to ignite and sustain interest in careers related to science, technology, engineering, and mathematics (STEM) among young learners.
Recently, the University of Notre Dame became a hub of excitement and innovation as it hosted students from The Portage School of Leaders High School, alongside a team from NASA Glenn. The highlight of the visit was the demonstration of the Advanced Noise Control Fan, an advanced piece of technology that operates in an outdoor environment. This fan is part of a test rig owned by NASA, specifically designed to explore quieter aircraft engine technology. The open rotor fan concept, which was the focus of the demonstration, is distinct because the engine fan operates without the typical protective cover. During the test, ground-based microphones were strategically positioned to assess the sound emissions produced by the fan as it operated at different speeds.
The involvement of the high school students, who are part of the Career Academy Network of Public Schools, extended beyond mere observation. Utilizing 3D printers available at their school, the students manufactured components for the open rotor test fan. These components, known as stator blades, are crucial as they guide and manage the airflow, ensuring that the large, exposed fan blades, characteristic of an open fan engine design, function smoothly and efficiently.
Rebecca Anderson, a junior at the high school, expressed her awe and excitement about the project. “It was beyond words,” she shared, reflecting on her experience. “The part I enjoyed most was when they got the fan running. It was really impressive to see how quiet it was. I feel like everyone involved in STEM would love to work for NASA, including me.”
Dr. Daniel Sutliff, a researcher from NASA Glenn, was an integral part of the mentoring team that guided the students. He emphasized the importance of such hands-on experiences in real-world research. “This is real-world, hands-on research for them,” Sutliff remarked. “If airlines are able to use technologies to make flight quieter and cleaner, passengers will have more enjoyable flights.”
The Advanced Noise Control Fan, which played a central role in this research, is temporarily housed at Notre Dame through a Space Act Agreement with NASA. The research and testing conducted with this fan are supported by NASA’s Advanced Air Transport Technology project, specifically under its Efficient Quiet Integrated Propulsors technical challenge.
### Understanding the Open Rotor Fan Concept
The open rotor fan concept is a significant departure from traditional aircraft engine designs. In standard engines, the fan blades are enclosed within a casing, which helps manage noise and improves aerodynamic efficiency. However, this enclosure also adds weight and complexity to the engine. The open rotor design eliminates this casing, allowing for a simpler and potentially more efficient engine. By removing the casing, engineers can focus on optimizing the fan blades and stator blades for better performance and reduced noise.
This concept is part of a broader effort by NASA and its partners to develop new technologies that will make air travel more sustainable. By reducing the noise and improving fuel efficiency, the aviation industry can minimize its environmental impact while providing a more pleasant experience for passengers.
### The Role of 3D Printing in Modern Aviation
The students’ use of 3D printing technology to create stator blades is a testament to how modern manufacturing techniques are revolutionizing the aviation industry. 3D printing, also known as additive manufacturing, allows for the creation of complex parts with precise specifications. This technology is particularly beneficial in aerospace applications, where lightweight and durable components are essential.
By engaging in this project, students are not only learning about cutting-edge aviation technology but also acquiring valuable skills in 3D printing and engineering design. These skills are critical for the next generation of engineers and scientists who will continue to push the boundaries of what is possible in aerospace technology.
### The Impact of STEM Education Collaborations
The collaboration between NASA, the University of Notre Dame, and Indiana high school students highlights the importance of STEM education partnerships. These collaborations provide students with unique opportunities to engage with real-world challenges and work alongside industry experts. By participating in such projects, students gain a deeper understanding of scientific principles and how they are applied in real-world scenarios.
Moreover, these experiences can inspire students to pursue careers in STEM fields, which are crucial for driving innovation and economic growth. As the demand for skilled professionals in these areas continues to rise, initiatives like this one play a vital role in preparing the workforce of the future.
### Future Prospects
As research into quieter and more efficient aircraft engines continues, the involvement of educational institutions and students will remain a crucial component. These collaborations not only advance scientific knowledge but also ensure that upcoming generations are equipped and inspired to tackle the challenges of tomorrow.
