Glenn High School Capstones
Acoustic Damping

NASA Glenn Research Center is always looking for dynamic new ways to connect students with the mission content of the Agency. The Office of STEM Engagement (OSTEM) has an interest in providing high school students with opportunities which they can pursue research in support of capstone projects based upon real NASA science and engineering mission content.

Acoustic Damping

Engineers in the Acoustics Branch at NASA Glenn know that noise is not just a nuisance. Cities need vibrant airports to enable local businesses to thrive, to join the global marketplace, and to draw the world to their doorstep. But as airport traffic increases, cities are faced with tough choices pitting the health and quality of life of thousands of residents living near airports against the greater good of their region’s economy.

Imagine what it would be like if we could keep aircraft noise down at the airport. That’s exactly what we have in mind at NASA Glenn. Rather than finding ways to live with noise, we’re conducting the research needed to understand the underlying physics that enables engineers to develop quieter airplanes. Innovators at NASA’s Glenn and Langley Research Centers are teaming to develop a compact, lightweight acoustic liner based on oxide/oxide ceramic matrix composite (CMC) materials.

Capstone Summary

For this capstone, students will develop acoustic liners with various shapes and patterns to test which design is the most effective at absorbing sound. Acoustic liners are typically placed in front of the turbo blades of a jet engine to absorb the noise generated by the engine.  Students will use an additive manufacturing process to replicate their designs and student designs will be tested in a student built acoustic impedance tube that will serve as the test rig for this capstone. Acoustic materials must be designed so that air can pass through the material.

Test Rig Components and Specifications

The impedance tube test rig will require a PVC Impedance Tube (Minimum 2-inch diameter with brass termination end), audio speaker, audio Amplifier, Function Wave Generator, High Precision Microphone, Oscilloscope, Data Acquisition Capabilities
