NAE™ Project: Shockwave Mitigation Research

Ladies & Gentlemen:

One of the biggest challenges to this project has been the mitigation of supersonic shock waves that will develop when the North American Eagle transitions from subsonic to transonic. This point of transition is called the sound barrier, or Mach 1. When the vehicle enters this region, shock waves are dispersed 360 degrees around the entire fuselage. The waves that propagate vertically between 90 and 270 degrees, and to the sides, do not interfere with our goal. The ones, however, that extend from 91 to 269 degrees could be detrimental to the attitude of the vehicle.

Airplane manufacturers, universities, and private laboratories around the world have been working on this problem since 2000. This project is called the Quiet Supersonic Platform (QSP). The goal of this Defense Advance Research Projects Agency (DARPA) originated project is to reduce the sound levels of supersonic aircraft so that future aircraft traveling above Mach 1 can do so without breaking the windows of your house and causing migratory challenges to the wildlife. Companies like Northrop-Grumman and agencies like NASA have built an aircraft called the Shaped Sonic Boom Demonstration (SSBD) project.

Next Steps

Our next step is to digitize the vehicle's exterior surface so we can analyze the structure using Computational Fluid Dynamics (CFD).

Very little information is known about shock waves generated from structures 4 inches off the ground. Our needs will be met when we can design a system to mitigate those shock waves and break the world land speed record in a relatively safe and controlled mode. The world will benefit when real time research might some day allow supersonic air travel over land. This research may lead to rockets that can be launched from airports.

facebook

We know a lot of our fans are on facebook.  Now the North American Eagle™ is on facebook as well! In fact many of our team members are also!  Tell your friends! It's fun!
