Six Degrees of Freedom Rocket Engine Duct Test
Many of today’s cutting-edge rocket engines use liquid natural gas (fuel) and liquid oxygen (oxidizer) to create thrust, which pushes the rocket forward and steers it when the angle of the engine is changed by gimballing. Transporting fuel and oxidizer into a gimballing engine... read More....

Using Digital Image Correlation to Measure Large Areas of Strain and Displacement
During component testing, strain and displacement data are often critical for fully documenting the behavior of the component. Strain is typically measured using bonded strain gages while displacement is measured with a string potentiometer or a linear variable differential... read More....

An Overview on Acoustic Emission Testing
When materials are cracking, deforming or otherwise becoming damaged, they produce a kind of sound. Sometimes, these sounds are loud and obvious. Other times, they are much more subtle, and to detect them, you need to use specialized equipment. Detecting these subtler sounds... read More....

Fluidized Catalytic Cracker Hot Spots
A far-too-frequent phenomenon seen in the refining world is the development of “hot spots” in the fluidized catalytic cracker (FCC). The damage can occur in the catalyst dump line or regenerator. These refractory lined vessels run very hot with regenerator internal... read More....
