Build Your Own Flying Lawn Mower

Posted by ryuzaki0 on from the lawn-ranger dept.

Ant writes "Ever seen a flying lawn mower (streaming; download 5.1 MB WMV file) before? I haven't. The WMV video file description says: 'FlyingThingZ Sky Cutter .40 V2 flying at Moon Lake's Annual Make a Wish Foundation Airshow for 2004'. More information can be found on the official Web site. Seen on Blue's News. My good friend, KaT, brought up a good question: 'Since lawns (also known as grass) live usually less than 6" from the ground, how would flying help them do their job better?'"

      This may be a way to speed up recruits to Iraq. Line them all up outside, and have the thing fly in low: Bzzzzzzzzzzzt, and everybody is nice and trim with a smooth flattop. It can also be used to weed out the squeamish, who duck and run when they see it coming.

    It's just a model airplane, not a real lawnmower.

    My niece was killed by a flying lawnmower when she was 4. The thing leapt off the ground after hitting a stump and the rotation of the blades created enough lift to set it into flight. You'd have expected the automatic cutoff to kill the motor, but my brother in law held on to the thing and it just took off. She was playing on the second floor balcony when my BIL and the mower caught her upside the temple. Took her scalp clean off.

    She's better now, but those first few hours were pretty harrowing.

      A guy at my local flying club where I used to live had built a flying mower, although it was red, not green. Really, the thing is just very lightweight and the thrust from the prop-engine is capable of supporting the weight of the craft (ie, it could fly in a vertical position like a helicopter just fine). You'll notice that during most of the flight, the thing has a fairly high angle of attack in order to provide the lift necessary.

      Actually, there was another guy (not sure if this was at the same flying club or some other place) that built a plane that looked exactly like Snoopy sitting on the top of his dog house like the Red Baron. Except, you could not tell what the lifting surface was (except for the bottom of the dog house). There were no wings sticking out or anything. It just looked like Snoopy sitting on his dog house. Pretty cool stuff.

      Pound for pound, model airplane engines have the highest horsepower of any internal combustion engine. Realize they are basic in design, with high-quality tolerances, and the bare minimum of metal to contain and cool. All unnecessary weight is dropped: there is no battery, no starter. The throttle works directly on the airfeed, which pulls the fuel by suction. (Occasionally helped by pressurized tanks.)

      They are simple. But they only have to do a simple job, and they do it well.

      If you look carefully, you'll notice that the body itself is an airfoil, with two horizontal control surfaces out of the back.

      I'm guessing the handle plus the square dome on top (which if you notice is completely hollow) function as vertical stabilizers.

      But yeah if you look at his flight, his stall angle is very close to vertical. I'd say about a 80 degree angle of attack... indicating that the engine is in fact providing most of the lift throughout flight... he's definitely doing some fancy tricks with those stabilizers to keep the lift up. When he goes into level flight is in the middle of the video when he bounces off the ground hahaha

  10. This is NOT what I expected by HawkinsD · · Score: 4, Interesting

    I assumed that "flying lawnmower" meant somethinglike the ill-fated HoverMow device: a British invention, I think, that eliminated the wheels on the lawnmower by making the blades create a strong downdraft. A flexible rubber skirt retrained the air cushion, and voila! a lawnmower that moved effortlessly, even over moderately uneven terrain.

    It did NOT, however, cut grass effectively, since the fan-effect tended to smush the grass down out of the way of the blades.

    So I was already writing the standard Slashdot "This is old news! I know all about this already" sneer in my head when I clicked on the FA.

    But then I saw this startling thing of... yes, of beauty. Fastinating. Even a lawnmower can be graceful.

    I am humbled.

    This thing (or a variant) has been around at LEAST 6 years (probably a lot longer, but that long at least I remember seeing a picture of it).

    The way it works is that the "deck" of the lawnmower itself is the wing. It is essentially a strange-shaped flying wing. The "bars" to the handle are the rudders, and there's elevons (combination aileron/elevator) behind the deck/wing. You can easily see the engine and propellor on the front as-is.

    Neat to see more pictures of it though, even if variants of it have been around for a while.
