About Me

I am an Aerospace Engineer with specialties in flutter, fluid structure interactions, and the use of CFD in a production environment. My dissertation shows how to improve the state-of-the-art unsteady CFD performance by 2 orders of magnitude. I am an engineer, a pilot, a marksman, a husband, and a dad.

Cold Gas Thruster Lab Experiment

Aerospace Engineering Laboratory:
Cold Gas Thruster:

Charles O'Neill
1st March 2001


A compressible flow supersonic nozzle using Nitrogen is experimentally tested. A
shadowgraph visualization system is setup. Specific impulse calculations are performed
from theoretical and experimental data. Compressible flow equations are reviewed.

Includes shadowgraph photos of Prandtl-Meyer fans aft of a nozzle.

Supersonic Nozzle Operating Above Design Pressure (250psi) with P-M waves 


The document is available here. This was an undergraduate laboratory experiment.
