Utah students aim to tow planes to the gate with a battery-powered, fuel-saving vehicle


UVU seniors unveiled a ‘tug’ that could help planes get to the gate without burning precious fuel.

(Francisco Kjolseth | The Salt Lake Tribune) Utah Valley University students test a new prototype electric-powered, autonomous aircraft tug, during a demo at Provo Airport on Friday, April 12, 2024. The tug would cut down on airplanes needing to start their engines early by moving them around at busy airports and reducing emissions and jet fuel costs.

Provo • Their four-wheeled contraption had worked perfectly before reporters showed up, Utah Valley University students promised, as they tinkered with it at the Provo Airport.

The creation, a welded frame encased in two wooden compartments roughly the size of coffee tables and powered by two electric engines, was supposed to tow the Diamond DA40 XLT — a single-engine prop plane weighing around 2,500 pounds — hitched to it.

It worked for a minute during its public debut Friday, before a broken sprocket — the metal wheel over which engine chains run — immobilized the machine for the rest of the day. But it would likely be an easy fix, UVU professor and project mentor Brett Stone said, and what is engineering if not a series of problems to solve?

Someone else’s problem, the students chimed in — this is likely as far as they’ll take this project before handing it off to the next capstone class — but a solvable one. And if it works, this student-led invention could revolutionize the airport taxiing process.

This model was just the prototype, a culmination of a school year’s worth of work from UVU engineering and computer science seniors. When it works — which it had just this morning, students repeated — it will be able to tow airplanes to and from their gates, controlled remotely by airport ground crews, pilots and its own autonomous driving abilities.

The traditional taxiing process, Stone said, is noisy, dangerous and wasteful. It requires planes to burn precious fuel and asks tarmac employees to come dangerously close to the spinning blades of aircraft engines.

“Jet engines are meant to be at 30,000 feet,” Stone said. “They’re not meant to push things around on the ground. And so, the way engineers think, I guess, I was like, ‘There’s got to be a better way.’”

The goal is to build a “tug,” as the contraption is called, robust enough to taxi commercial jets — and bring it to market.

Aircraft tugs aren’t new — but fully electric, remote-controlled ones with the capacity to tow a commercial jet could be the industry’s next frontier. There’s a patent application pending for this specific model, Stone said, and future senior capstone classes will help scale it for commercial use. A commercial product could be ready in the next two years, Stone said.

The tug would cut down on airplanes needing to start their engines early by moving them around at busy airports and reducing emissions and jet fuel costs.

“It’d be really cool to see it progress, to see it reach the full-size Boeing airline capacity,” said UVU graduating senior Kolby Hargett. “I think another year from now, [future students] can get started scaling it into something larger, now that the idea’s here and a lot of the ground work’s done.”

This was a first-of-its-kind collaboration between graduating seniors in UVU’s engineering and computer science departments. Engineers, like Ammon Traden, worked on the design and the mechanics. Computer scientists, like Cache Fulton and Riley Pinkham, figured out the software. Their combined skillset was what it took to turn Stone’s vision into a real, operable product.

“We were blessed that Kolby knows so much about electricity,” Traden said. “He helped us so much with this.”

It’s also the most ambitious capstone project UVU engineering students have undertaken, said professor and mentor Matt Jensen — and the most practical. Students will enter the job market with real-world experience and a demonstrable, physical product they can say they built from the ground up.

“While it’s not perfect, and obviously it did have its challenges today, I think just recognizing … that they’re about to graduate and go into the industry, I feel very confident that they’ll be good engineers.”

And one day in the near future, the students imagine, they might get to sit on a plane being towed by something they helped create.

“Next, we’re going to come for the plane,” Fulton said.

Final Prediction

This projection could be way off because this draft has a lot of parity and the Jazz could very well trade some of their picks. With that said, I predict that the Jazz select Nikola Topic with the 10th pick. For the 29th pick, The Jazz go for Ryan Dunn. For the 32nd pick, I predict that the Jazz select Jaylon Tyson. I think the Jazz will almost make a trade or two tomorrow but don’t quite pull the trigger.

4 Utah Jazz rumors to watch before the NBA Draft

4 Utah Jazz rumors to watch before the NBA Draft


The Tribune’s Andy Larsen breaks down the latest reports.

(Francisco Kjolseth | The Salt Lake Tribune) Brooklyn Nets forward Mikal Bridges (1) tries to evade the block attempt by Utah Jazz center Walker Kessler (24) during NBA basketball in Salt Lake City Monday, Dec. 18, 2023.

The NBA Draft starts Wednesday, and the rumor mill is heating up around the Utah Jazz. Here’s the latest news, along with my reaction to the possibilities.

Trading for Mikal Bridges?

Rumor: Yahoo’s Jake Fischer reported that the Jazz are one of the teams interested in trading for Brooklyn wing Mikal Bridges, along with Houston and New York. Bridges is one of “Utah’s most aggressive aspirations,” Fischer wrote.

Reaction: The Nets have repeatedly declined to trade Bridges despite it probably making sense for the franchise to do so. Instead, they’ve been asking for more than three first-round picks in return for the 27-year-old.

Bridges would make the Jazz significantly better; he’s developed himself into a 20-point-per-game scorer while also being a solid defender. He’s the two-way player with size that these most recent playoffs have shown are extremely valuable. (Though we should note here that he was a far better player before the All-Star break than after it last year.)

The problem is that it’s not immediately clear that the Jazz would be a playoff team even with Bridges — he was an eight-win player last season, and the Jazz finished 15 wins short of the No. 10 seed. For an acquisition of Bridges to make sense, Utah would probably need to acquire other good players around him and Lauri Markkanen to get up in that 45-win range required to make the playoffs in the West. Still, it could be an exciting first step.

Trading for Zach LaVine?

Rumor: The Bulls “remain active” on trade negotiations sending out Zach LaVine involving the Jazz and the Philadelphia 76ers, according to NBC Sports Chicago’s K.C. Johnson. However, reporter Marc Stein disagreed with the report, saying he had been “advised to dismiss Utah’s interest.”

Reaction: Johnson’s a quality veteran reporter, but I agree with Stein. While I haven’t heard recent updates, Jazz personnel earlier this year indicated that LaVine wasn’t a logical option in the pre-trade deadline market given the Jazz’s place in the standings, LaVine’s poor record of availability, and especially his high contract that pays him a combined $138 million over the next three years.

I don’t suspect circumstances have changed enough since to make a LaVine trade make sense now, at least not a trade in which the Jazz are giving up assets. If anything, it might require Chicago to send out assets to push the Jazz to take on LaVine’s deal.

Signing Tobias Harris?

Rumor: The Athletic’s Shams Charania reported that the Jazz and the Detroit Pistons “are expected to be the strongest suitors for Tobias Harris,” who is a free agent this summer after his 5-year, $180 million albatross of a deal ended with the 76ers.

Reaction: The Jazz will likely have about $40 million in cap space this summer. Some of that room the franchise anticipates using on Markkanen’s renegotiation and extension as the Finnish star enters the final year of his current contract.

Harris is theoretically someone who could help the Jazz. At this point in his career, he’s statistically pretty average across the board — his shooting, rebounding, passing, steals, and block rates are just around the 50th percentile, maybe a bit higher. Even average, though, would make Harris the Jazz’s best wing by a lot.

He turns 32 this summer, so Harris doesn’t make sense for the Jazz’s long-term future, and signing him would also mean fewer minutes for last year’s No. 9 pick, Taylor Hendricks. But if they could get him on a short-term deal for a discount, he could also be a tradable piece in a move later while helping the Jazz improve now.

Looking to move up?

Rumor: Multiple reporters indicated that the Jazz are looking to move up in the draft using the No. 29 pick and the No. 32 pick. First, ESPN’s Jonathan Givony reported Monday morning that the Jazz are looking to trade the two picks for a “pick in the late teens.” Arizona sports radio host John Gambadoro reported that he believed that the Suns had had discussions with the Jazz, sending the No. 22 pick to Utah for No. 29 and No. 32. Fischer, meanwhile, floated the idea of the Jazz acquiring No. 17 from the Lakers in exchange for the two picks.

Reaction: Jazz general manager Justin Zanik acknowledged that the club has reservations about having six first- or second-year players on the roster next season, the logical outcome if the team makes all three selections on Wednesday. So the Jazz consolidating these picks in this fashion follows that line of thinking, especially if they are targeting a player they believe is significantly better than what’s available around the turn of the draft.

My only concern is that, in general, teams trading up in drafts get a little less value than those trading down when you study the issue analytically. The NBA Draft Pick Trade Simulator at nbasense.com is a good tool for looking at this — trading No. 29 and No. 32 for No. 17 is a pretty fair deal, but trading those picks for No. 22 would be analytically a bad idea. That’s especially true in a “flat” draft, where players’ values are considered pretty close throughout the first round.

If the Jazz are going to defy the analytics, they should be really sure that the player they’re acquiring with the higher pick is worth giving up two chances to place bets further down in the draft.
