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
