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)

A case of suspended animation?

At first glance this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known as Leo A. Its few million stars are so sparsely distributed that some distant background galaxies are visible through it. Leo A itself is at a distance of about 2.5 million light-years from Earth and a member of the Local Group of galaxies; a group that includes the Milky Way and the well-known Andromeda galaxy. Astronomers study dwarf galaxies because they are very numerous and are simpler in structure than their giant cousins. However, their small size makes them difficult to study at great distances. As a result, the dwarf galaxies of the Local Group are of particular interest, as they are close enough to study in detail. As it turns out, Leo A is a rather unusual galaxy. It is one of the most isolated galaxies in the Local Group, has no obvious structural features beyond being a roughly spherical mass of stars, and shows no evidence for recent interactions with any of its few neighbours. However, the galaxy’s contents are overwhelmingly dominated by relatively young stars, something that would normally be the result of a recent interaction with another galaxy. Around 90% of the stars in Leo A are less than eight billion years old — young in cosmic terms! This raises a number of intriguing questions about why star formation in Leo A did not take place on the “usual” timescale, but instead waited until it was good and ready.

Raditladi basin, imaged during MESSENGER first Mercury flyby and named in April 2008, is intriguing for several reasons.

The Curious Case of Raditladi Basin

When astronomers first looked at images of a supernova remnant called Cassiopeia A, captured by NASA NuSTAR. The mystery of Cassiopeia A Cas A, a massive star that exploded in a supernova more than 11,000 years ago continues to confound scientists.

The Case of Missing Iron in Cassiopeia A

This infrared image from NASA Spitzer Space Telescope shows a swirling landscape of stars known as the North America nebula. Clusters of young stars about one million years old can be found throughout the image.

The Case of the Martian Boulder Piles

This image from NASA's Mars Reconnaissance Orbiter (MRO) was originally meant to track the movement of sand dunes near the North Pole of Mars, but what's on the ground in between the dunes is just as interesting! The ground has parallel dark and light stripes from upper left to lower right in this area. In the dark stripes, we see piles of boulders at regular intervals. What organized these boulders into neatly-spaced piles? In the Arctic back on Earth, rocks can be organized by a process called "frost heave." With frost heave, repeatedly freezing and thawing of the ground can bring rocks to the surface and organize them into piles, stripes, or even circles. On Earth, one of these temperature cycles takes a year, but on Mars it might be connected to changes in the planet's orbit around the Sun that take much longer. https://photojournal.jpl.nasa.gov/catalog/PIA22334

This image from ESA Herschel Space Observatory reveals a suspected ring at the center of our galaxy is warped for reasons scientists cannot explain. The ring is twisted so that part of it rises above and below the plane of our Milky Way galaxy.

The Case of the Warped Galactic Ring

The Case of the Missing Crater Rim

In this observation from NASA's Mars Reconnaissance Orbiter, these two craters perched at the edge of an outflow channel, appear to have lost a portion of their crater rims during a flood event. Alternatively, it is also possible that the craters impacted the edge of the outflow channel after the flood occurred and we are seeing the difference in the strength of the material impacted. https://photojournal.jpl.nasa.gov/catalog/PIA21881

This image from NASA Cassini spacecraft shows the location of an area known as Sotra Facula on Saturn moon Titan. Scientists believe the Sotra Facula region makes the best case for a cryovolcanic, or ice volcano, region on Titan.

This MOC image shows a suite of rings on the martian northern plains. Each ring marks the location of a filled and buried or, in some cases, mostly-filled and nearly-buried impact crater

Ring Things

This frame from a movie is based on data from NASA Cassini spacecraft and shows a flyover of an area of Saturn moon Titan known as Sotra Facula. Scientists believe Sotra is the best case for an ice volcano, or cryovolcano, region on Titan.

MSFC_2020_XP_SLS_P_ 005_PD002-Test-Case-TTF-4697 LOX Tank Test to Failure06242020 post test_168

Photo shows how the Space Launch Sysetm (SLS) rocket liquid oxygen tank failed during a structural qualification test at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The photos show both the water flowing from the tank as it ruptured and the resultant tear left in the tank when it buckled during the test. Engineers pushed the liquid oxygen structural test article to the limits on purpose. The tank is a test article that is identical to tanks that are part of the SLS core stage that will produce 2 million pounds of thrust to help launch the rocket on the Artemis missions to the Moon. During the test, hydraulic cylinders were then calibrated and positioned along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. For the test, water used to simulate the liquid oxygen flows out of the tank after it ruptures. The structural test campaign was conducted on the rocket to ensure the SLS rocket’s structure can endure the rigors of launch and safely send astronauts to the Moon on the Artemis missions.

Gullies in a Central Pit Crater

Sometimes a central pit forms inside some Martian craters, especially when there substantial ground ice. Such is the case in this observation from NASA Mars Reconnaissance Orbiter spacecraft. Sometimes what we call "mass wasting" processes (think small avalanches or landslides) occur on the slopes of the central pit. We took this image to search for any recent activity that would add to or modify previously identified gullies. http://photojournal.jpl.nasa.gov/catalog/PIA20005

Olympia Undae

This VIS image shows part of Olympia Undae, a vast sand sea near the north pole. In regions with limited sand abundance, individual dunes form and the surface below the dunes are visible. This is the case at the top of the image. When sand abundances grow, the individual dunes coalesce into a sheet of sand hiding the underlaying surface. This is the case at the bottom of the image.

Eye of Supertyphoon Yuri

This detailed view of the eye of Supertyphoon Yuri (19.0N, 140.0E) shows the bowl shaped structure of the eye wall. The eye cylinder descends almost to the ocean surface, some 45,000 to 50,000 ft. In this case, the eye is filled with clouds but in most cases, the cylinder is at least partially clear so that the sea surface is visible. The storm at this time was at it's most intense with maximum sustained winds of 165 mph and gusting to 200 mph.
