A Brief History of Terre Haute

Terre Haute is a city of about 60,000 people located in west-central Indiana. The name comes from French for "High ground" and was assigned by early French explorers. William Henry Harrison established Fort Harrison in the area during Tecumseh's war in 1811, and Terre Haute was platted in 1816. In the early 1800s steamboat traffic on the Wabash brought goods to and from the city. The Wabash & Erie Canal connected Terre Haute to cities like Lafayette & Fort Wayne on the upper Wabash River when it came to town in 1849. The canal did not last long after railroads came to town. Chauncey Rose founded the Terre Haute and Richmond Railroad, which provided service to Indianapolis in 1852. Terre Haute became an industrial hub after the Civil War, and its population peaked at around 70,000 in 1960. By 1980, when the Midwest had become the Rust Belt, the population had dropped to about 60,000 and it has remained relatively level since then. Since then industry in Terre Haute has recovered somewhat, and there are now several aerospace related companies in town.

VEXTEC Laboratory Group

VEXTEC Laboratory Group specializes in testing components under conditions similar to those experienced in gas turbine engines. They utilize small gas turbine engines normally used by serious radio control hobbyists to create a hot stream of gas. A powerful electric motor rotates the test articles at high speed in this gas stream. By doing this they can simulate the high temperature and high rotational speed at a much lower cost than running a full size gas turbine engine.

The facility was constructed in 2008 and is located just west of the airport and north of Tri Aerospace. The Terre Haute Economic Development Corporation was instrumental in bringing the company to Terre Haute. VEXTEC's headquarters is located in Nashville, Tennessee. VEXTEC Laboratory Group has performed testing for the U.S. Air Force and commercial customers.
