On August 23, 2023, the Pettinger Engine Collection opened in its permanent home at the UNT College of Engineering at Discovery Park. Donated by alumna Hedwig Pettinger and her husband, Wes, it includes hobby engines for aircraft, boats, and cars, and many other special items. The collection showcases Wes Pettinger’s lifelong passion for the combustion engine, which he has chosen to share with our current and future students. A portion of the collection is utilized in the education of our engineers and K-12 students.

Demonstration and Travel Engines

A selection of running engines has been set aside from the permanent collection to travel around the DFW area and aid in the education of K-12 students. These engines are also available to UNT students and faculty for educational purposes. The traveling collection engines are duplicates to those in the permanent collection.

Over the years, Wes and Hedwig collected a selection of items that they hold a bit closer to their heart. These include a model rocket that won Hedwig a competition, a model of Jules Verne’s Albatross, a Honda SuperCub, and many more intriguing pieces.
