The Orion launch abort system and crew module test articles undergo stacking at Lockheed Martin’s facilities near Denver in preparation for acoustic testing on Aug. 15, 2011. To emulate the sound pressure levels experienced at launch, the tests exposed Orion and its launch abort system to acoustic levels exceeding 150 decibels, while hundreds of instruments record the vehicle’s response.

Technicians position microphones around the Orion launch abort system and crew module test articles in preparation for the second round of testing in the acoustic chamber at Lockheed Martin’s facilities near Denver on Aug. 16, 2011. The vehicle was bombarded by acoustic levels of 150 decibels to simulate conditions during launch and abort if necessary. Part of Batch image transfer from Flickr.

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

Modern jet engines are loud, but they used to be much louder. NASA’s Glenn Research Center has been at the forefront of the nation’s efforts to reduce aircraft engine noise for over 70 years. During this time, the center has built an array of test facilities to carry out this work, culminating in the Aero-Acoustic Propulsion Laboratory (AAPL), a world-class noise-reduction research facility. The AAPL, referred to as “the dome,” contains multiple test rigs enclosed in a large, echo-free chamber. The unique 130-foot diameter and 65-foot-high hemispherical structure stands out on Glenn’s campus. Its triangular sections make it appear like a golf ball rising from the ground. The interior is covered in spiky, fiberglass sound-dampening wedges and an overhead array of microphones that capture engine noise data.

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.

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)
