Hybrid rocket fuel research being done by a University of Alabama in Huntsville (UAH) mechanical engineering doctoral student could hasten the day when a simpler, safer, more economical rocket engine propels space missions.
At UAH’s Johnson Propulsion Center, Matthew Hitt has experimented with varying solid fuel grain sizes to see how they burn at different combustion chamber pressures and oxidizer flow rates in an effort to improve the performance of hybrid engines.
“This is another step in making hybrids – which are a safer alternative to either solid or liquid engines – more practical for actual application,” he says.

The luxury vehicles assembled by workers at the Mercedes-Benz plant in Tuscaloosa County helped the German automaker set sales records in June.
On a global scale, Mercedes sold more than 898,000 vehicles from January to June, an all-time high and up 15 percent from the previous year’s first half, the company reported. That total includes a 25 percent improvement in sales of SUVs, including products from the Alabama plant. Local workers built the M-Class and GL-Class SUVs, which are shipped around the globe.

Anecdotal evidence of the nation’s reshoring trend can be found from coast to coast.
Data from the Reshoring Initiative, however, shows it’s primarily southern states that are seeing the benefits of manufacturing companies returning production from overseas.
The group’s numbers show that the south easily accounted for more jobs reshored to the U.S. than the rest of the country combined.
