Acoustic Casing Treatment Testing Completed in the W-8 Single Stage Axial Compressor Facility at NASA Glenn. Four different over-the-rotor acoustic casing treatment concepts were tested along with two baseline configurations. Testing included steady-aerodynamic measurements of fan performance, hotfilm turbulence measurements, and inlet acoustic measurements with an in-duct array.

Operators at the E-3 Test Stand at NASA's John C. Stennis Space Center completed 32 acoustics tests April 16-28, designed to gather critical information for future space launches. Stennis operators investigated lift-off acoustics that can damage space vehicle components by testing the benefits of injecting water onto the upper surface of the launch pad to suppress sound. The Stennis tests provided critical data to determine what can be gained from this approach.

At Goddard, the engineers use the Acoustic Test Chamber, a 42-foot-tall chamber, with 6-foot-diameter speaker horns to replicate the launch environment. The horns use an altering flow of gaseous nitrogen to produce a sound level as high as 150 decibels for two-minute tests. That’s about the level of sound heard standing next to a jet engine during takeoff. The 6-foot-wide horns in this 42-foot-tall chamber can produce noise at levels as high as 150 dB. During the acoustics test, the speakers can still be heard outside of its insulated massive metal doors.

NASA's SPHEREx observatory is installed in the Fiesta Area at BAE Systems in Boulder, Colorado, in July 2024. The observatory is surrounded by speaker stacks used to perform acoustics testing, which subjects the spacecraft to the acoustics loads that it will experience during launch. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will create a map of the cosmos like no other. Using a technique called spectroscopy to image the entire sky in 102 wavelengths of infrared light, SPHEREx will gather information about the composition of and distance to millions of galaxies and stars. With this map, scientists will study what happened in the first fraction of a second after the big bang, how galaxies formed and evolved, and the origins of water in planetary systems in our galaxy. https://photojournal.jpl.nasa.gov/catalog/PIA26540

The SpaceX Crew Dragon spacecraft for its first crew launch from American soil arrived at the launch site on Feb. 13, 2020. NASA and SpaceX are preparing for the company’s first flight test with astronauts to the International Space Station as part of the agency’s Commercial Crew Program. The SpaceX Crew Dragon will launch atop a Falcon 9 rocket with NASA astronauts Bob Behnken and Doug Hurley from historic Launch Complex 39A from NASA’s Kennedy Space Center in Florida. The team completed acoustic testing of the spacecraft as part of its final testing and prelaunch processing in a SpaceX facility on nearby Cape Canaveral Air Force Station. Photo credit: SpaceX

Direct Field Acoustic (DFA) Testing was successfully completed on the Exploration Flight Test-1 (EFT-1) crew module at the Lockheed Martin Waterton Reverberant Acoustic Lab (RAL) on March 1, 2016. DFA Testing is an alternative method for spacecraft module acoustic qualification and acceptance verification that is being investigated for use in the Orion program. Its portability would allow testing at KSC and eliminate the transportation risks and associated cost and schedule of performing this verification activity off-site. Two configurations were tested; one representing the future reverberant acoustic comparison test and one representing the future configuration for the Artemis I crew module. A mock-up of the service module without the fairings will also be tested to gather volumetric data to decide viability of performing DFA Testing on the Static Test Article (STA) SM in the 2016 Fall. Data will be used to develop predictive algorithms for future tests.

Title: W-8 Fan Acoustic Casing Treatment Test on the Source Diagnostic Test Rotor Alone Hardware Program: Advanced Air Vehicles Program (AAVP) Project: Advanced Air Transport Technology (AATT) Sub-project: Aircraft Noise Reduction (ANR)   Weekly Highlight: ·         Acoustic Casing Treatment Testing Completed in the W-8 Single Stage Axial Compressor Facility: Testing of Acoustic Casing Treatments on the Source Diagnostic Test (SDT) rotor alone hardware which had begun in early January was completed on Thursday, February 16th. Four different over-the-rotor acoustic casing treatment concepts were tested along with two baseline configurations. Testing included steady-aerodynamic measurements of fan performance, hotfilm turbulence measurements, and inlet acoustic measurements with an in-duct array. These measurements will be used to assess the aerodynamic and acoustic impact of fan acoustic casing treatments on a high bypass ratio fan at TRL 3. This test was the last of 3 planned tests of potential over-the-rotor acoustic casing treatments. The first treatment test was completed in the Normal Incidence Tube (NIT) at Langley Research Center (LaRC) in Fall 2015 and the second was completed on the Advanced Noise Control Fan (ANCF) in the Aero-Acoustic Propulsion Laboratory (AAPL) in Winter 2016. This work is supported by the Aircraft Noise Reduction (ANR) subproject of the Advanced Air Transport Technology (AATT) Project. (POC: LTV/ Rick Bozak 3-5160)

Orion’s service module for NASA’s Artemis 1 mission was moved from a test stand to a test cell inside the Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on May 22, 2019. With microphones, strain gauges and accelerometers attached, the service module will undergo acoustic testing to check for flaws, the latest step in preparing for the agency’s first uncrewed flight test of Orion on the Space Launch System (SLS) rocket. Artemis 1 will be the first mission launching Orion on the SLS rocket from Kennedy’s Launch Pad 39B. The mission will take Orion thousands of miles past the Moon on an approximately three-week test flight. Orion will return to Earth and splashdown in the Pacific Ocean off the coast of California, where it will be retrieved and returned to Kennedy.

A NASA intern sets up ground recording system (GRS) units in California’s Mojave Desert during a Phase 2 rehearsal of the agency’s Quesst mission. The GRS units were placed across miles of desert terrain to capture the acoustic signature of supersonic aircraft during rehearsal flights and in preparation for the start of the actual tests.

The SpaceX Crew Dragon spacecraft is in the anechoic chamber for electromagnetic interference testing on May 20, 2018, at NASA's Kennedy Space Center in Florida. The Crew Dragon will be shipped to the agency's Plum Brook Station test facility at Glenn Research City in Cleveland, Ohio, for testing in the Reverberant Acoustic Test Facility, the world's most powerful acoustic test chamber. Crew Dragon is being prepared for its first uncrewed test flight, targeted for August 2018.

The Orion crew module for Artemis I, shown here on May 2, 2019, recently underwent Direct Field Acoustics Test (DFAT) where it was exposed to maximum acoustics levels that the vehicle will experience in space. Spacecraft response and sound pressure data were collected with microphones, strain gauges and accelerometers. The max decibel level was -12dB.
