Competition heated up this week as the annual Mechanical Engineering Technology (MET) Stirling Engine Competition returned once again at RRC Polytech’s Notre Dame Campus.

The competition is the culmination of first-year MET students’ hard work as they built their own Stirling engines from scratch during their Basics of Manufacturing course.

During the noon hour, the halls of the Skilled Trades and Technology Centre (STTC) were lined with the student-built engines, running on nothing but the ambient temperature and ice.

A Stirling engine works by converting heat energy into mechanical energy. The engine uses a temperature differential between two surfaces — in this case, one surface is much colder than the other because of the ice — to take advantage of the expansion and contraction of air, which helps move a piston. The engine was named after its inventor, Robert Stirling.

After being treated to a pizza lunch, students placed the base of their engines atop of ice water and left to stabilize before judging occurred. The engines were judged on categories such as Truest Flywheel, or Fastest Engine.

Guests were also invited to participate in the fun during the competition by voting for Best Colour Scheme, and Best Flywheel Design categories.

“For a lot of people, this is really their first time getting their feet wet in this kind of an environment,” Nik Graham, the winner of the Truest Flywheel distinction, said. “So this is more like a celebration, like, ‘you did this, this is a machine that did not exist before you joined this class.’”

The competition is a fun celebration for the MET students and their hard work and dedication to complete their first year and provides them with the emotional boost to get through the exam period, according to their instructor, Serge Broeska, when he gave a speech to start the event.

This was the first Stirling Engine competition to return to RRC Polytech since 2019, after COVID-19 restrictions forced the College to pause the popular event. Leon Fainstein, Serge’s predecessor, started the annual event about two decades ago, and has been a MET tradition ever since.
