New Meeting Schedule

SAAA monthly meetings now occur at 7pm on the second Thursday of the month. Meetings are held at Macatawa Bay School in the planetarium. Our meetings are open to the public. See event calendar for details.

Looking for New Members

Wanted – astronomy enthusiasts. The SAAA wants to grow the astronomy community in West Michigan. If you have an interest in astronomy, telescopes or just curious about the cosmos, we’d like to hear from you.

What’s Up in the Sky

What’s Up in the Sky – May, 2013 Looking for something really cool to observe, something you’ve never seen before that you can now show the kids? This could be your month. And I am not talking about the rings of Saturn or craters on the Moon, both of which can be easily observed these …

What’s Up in the Sky

What’s Up in the Sky – April, 2013 This Month, Things You Can Actually See Twice. That’s how many times I was able to spot the topic of last month’s column, Comet PANSTARRS. Even knowing just where and when to look and having the help of binoculars, I was barely able to pick it out …

The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA's Glenn Research Center being tested.

The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA's Glenn Research Center, is being tested to determine the acoustic impact of engine configurations on low sonic boom aircraft for the High Speed Project of the Fundamental Aeronautics Program. The High Speed Project is a multi-center effort to develop and test the technologies of a new generation of aircraft that can fly at supersonic speeds. Glenn's research involves predicting the airport noise of these novel aircraft by examining innovative airframes and propulsion integration that are different from the conventional tube-and-wing aircraft observed at commercial airports. Inside the aeroacoustic dome, this generic, low-fidelity aircraft engine exhaust model features twin rectangular nozzles. Researchers are investigating the impact of having the propulsive exhaust come from the slot nozzles atop the aircraft. Testing the proposed components of these high- speed aircraft will help manufacturers meet the noise standards required around the nation's airports. Image Credit: NASA/Bridget R. Caswell
