LUCY THM: The Fine Line Between Genius And Insanity

From designer Pietro Terzi, the LUCY THM
Umm, the LUCY THM is, kinda unusual(!)

I’m guessing most of you would be quick to push this unusual bizarre looking aircraft well over on the ‘insanity’ side of the table, but I’m not so quick to do so. I love outside-the-box thinking, tho I will admit that this seems to be a little more like inside-the-padded-room thinking. However, I’ve learned that it’s far more wise to wait and see if someone is on to something good before I declare that it won’t work.
The machine is called the LUCY THM (I don’t know why) and it comes from Italy and designer Pietro Terzi. And while it appears that it hasn’t flown, you should take note that Terzi has designed other aircraft as can be seen in the last image (after the jump). It’s also important to note that the workmanship on this carbon fiber airframe appears to be very excellent, which again should add some credibility to the concept. Construction on the project began in 2007.
The LUCY THM was conceived to be a ’Personal Air Vehicle’ or PAV. That’s one of the reasons that it has those odd looking pods hanging below the cockpit… you sit in it more like a motorcycle, with your legs down in the pods. It seems this arrangement is meant to make you feel more like the airplane is part of you, or as the LUCY website says: “a ‘technological suite’ worn to get yourself about in the air”.
If I read the specs right, it has a max takeoff weight of about 880 pounds, so part of the idea here is to have a lightweight airframe coupled with lots of thrust to make it have great STOL performance. And this is where I see something that I think makes a lot of sense in the design. You can see from the images that the prop has a huge diameter, over 10 feet, and it's driven by an 84hp Hirth 2-stroke engine. With the constant speed prop geared way down, this little machine should have some serious thrust! And one thing I think we overlook in aircraft design is the ‘thrust’ we get out of our engine/prop combinations. Horsepower doesn’t really mean much if a lot of it is lost at the prop. Large slow turning props can move huge amounts of air, so I’m prepared to give the designer a lot of credit for working to make an aircraft with more thrust than its weight (which is their claim). This is the reason they actually call it ESTOL (Extremely Short Takeoff and Landing), and why they also claim it would climb at 3,000+ feet per minute. Max cruise is claimed at 130 mph.
