Deja Vu All Over Again!


With apologies to the great Yogi (Berra, not Bear), Sunday's go-for-broke flight did exactly that under pretty blustery conditions. Our Miners spent a late night repairing the plane and did the job so well that you'd never know the wing was something of a pretzel after Saturday's wreck. They reattached and reinforced the rear bulkhead previously ripped from the fuselage, loaded nearly all of the craft's design payload, double-checked the engines and planned strategy with pilot Kelly O'Connor.

The payload adjustments seemed to have done the trick because the craft built much-needed speed and Kelly began to lift Whalicus skyward (a big improvement over Saturday's flight), but just as a flight official raised his green flag to signal a legal lift-off, things went wrong; REALLY wrong. In just a blink of an eye the impact-weakened tail boom began to separate from the fuselage with the obvious loss of control, and it was all over.

The craft plowed sideways into the ground, throwing grass and (yes!) divots of turf across the runway before skidding to a halt.

We'll just let you suffer through the sequence..........

You'd never know it took about half a second to do all this......

And this..........

And finally, aside from the groans rising from the crowd, all was quiet.

Oft times when disaster strikes, there is something to be learned, a silver lining, as they say.
One thing that the students could brag about was the overall robustness of their design and construction. Much of the plane remained intact, as it simply broke into two pieces making recovery a relatively simple process. If you want to see what it COULD have looked like, read on..............

Ladies and Gentlemen, Please Replace Your Divots......


The admonition you see as you enter a golf course was oddly appropriate this morning as "Whalicus" plowed a furrow into the grass runway upon takeoff. The Miners may have taken their mining heritage a little too seriously today and burrowed through the turf when a rough spot caught a wing tip just as the craft was lifting off.

A rough way to go after coming into the Open Class flying events in first place. The team's second-place awards in both engineering and oral reports gave them the highest overall placement, but all is not lost.

After a long, painful walk back to the pit area the group had repaired much of damage by mid-afternoon, and all that remained was to carefully (?) haul the 11-ft aircraft to the 3rd floor hangar at Motel 6 and replace the wing's surface material.

They figure many of the other aircraft have pretty much maxed out their lifting capacity at levels well below what S&T's bird can handle, so the open class championship is still within their grasp. All they have to do is get airborne with the day's heaviest payload
Oh, yeah, one of the event officials did help the Miners replace the divots.....

Don't feel bad for the Miners. If you want to see what a few other teams have experienced, just continue below.

Let 'em Fly! S&T's Advanced Aero Vehicle Group Kicks Off 2008 Design Team Season!

Now that St. Pat's and Spring Break are over, the first major '08 design team has emerged from S&T's own somewhat smaller-scale 'skunkworks'. AAVG's new flyer was christened "Whalicus" just two days ago, and lifted off just great on its first flight at the Cuba, Missouri airport. Good thing they built a complete extra wing because the landing was a little, uh, rough.

Fast forward to the Lockeed/Martin-hosted SAE Aero competition in Ft Worth. The new S&T-labeled bird sailed through tech inspection with but two minor, and easily corrected, glitches.

Now it is down to an early-morning trek to nearby Thunderbird Flying Field and the two-day flyoffs with ever and ever increasing payloads. While the weather looks perfect for flying, the 2008 event throws a new challenge at the team. They'll eschew the paved runway for a grass landing strip (and have designed the landing gear accordingly), so flying should be uneventful, but landing and take-offs should have a bit more drama.

Hang on to your seats, Miners,and stay tuned; it is going to be an interesting ride!

Free falling

Despite the following sequence of events, UMR's AAVG team did very well in the Aero Design East competition last weekend in Fort Worth, Texas. The official results should eventually be posted by SAE.

UMR's advanced areo vehicle on the runway, preparing for takeoff...

It takes a lot of guts to name your expensive remote-controlled airplane after a dude who got his liver picked apart by a bird every day. But that's exactly what the UMR AAVG team did. UMR team members entered their aircraft, Prometheus, in a competition that drew about 50 design teams from North and South America to Texas this past weekend. (We would have gone with Icarus for the name of the plane; that would have been really bold and daring.)

The UMR team excelled during design reports to a panel of judges. And, Prometheus was soaring high once the actual flying part of the competition started too. It looked like UMR might even be one of the very top teams. But, alas, Prometheus had one hard landing followed by an ill-fated flight involving the loss of its tail. The wind gods were angry in Texas and lots of the planes were falling from the sky -- one of them hit a car in the parking lot of the airfield. More photos, including shots of Prometheus' doomed flight, to follow....

Update: We just heard back from the team and the crash apparently didn't hurt them much. They finished fourth overall (unofficially) in the open class part of the competition. Not too shabby. Not too shabby at all.

P.S. We've been thinking about this Prometheus thing and, on second thought, the UMR team might have been thinking about the time Prometheus stole fire from Zeus and gave it to mortals. Also, Prometheus's liver had the ability to regenerate itself kinda like the UMR team members have the ability to fix their plane after crashes. Or something.

Aerospace engineering students like to make things fly

Wouldn't it be fun to put this baby into a dive, fly it right into your neighbor's back yard while he's out there grilling hamburgers, buzz his head...and stuff? Yeah, that would be so cool. Anyway, the AAVG team is on its way to Texas to participate in an annual aero design competition. We'll have photos of UMR's bird in flight by Monday.

P.S. UMR students are also pretty good at designing remote-control helicopters.
