On the first test he used a two-bladed propeller, with a small pitch angle which required full throttle to keep flying. It is powered by a single large brushless electric motor borrowed from the OpenPPG project. Interestingly he kept the rudder controls on pedals instead of moving it to the stick, so the stick only controls the elevator. This gives the aircraft passive stability, because as it rolls to a side, the upper wing’s lift decreases and the lower wing’s lift increases, forcing the plane to correct itself. For roll stabilization he angled up the wings noticeably, adding dihedral. To keep the plane simple, he got rid of ailerons entirely. For a taste of what’s going on here, the wings have aluminum tube spars and are made of hot-wire-cut styrofoam sections. He recently flew the fourth ultralight, which he designed and built himself. Peter Sripol really likes building gravity defying death traps. Looking for some more don’t-try-this-at-home projects to gawk at? Look no further than who like, has managed to gain his own Hackaday tag.Ĭontinue reading “Fifty Motored Paraglider Partly Flies, Partly Glides” → Posted in Transportation Hacks Tagged aviation, electric flight, peter sripol, ultralight Does every experiment need to end in absolute success in order to have fun and learn lessons that can be applied to the next iteration? Definitely not! We applaud for being willing to fail- although, we have to admit, failing is a lot easier when you’ve already got a parachute of sorts deployed! While the experiment was essentially a success, it was also a failure due to not having enough power, too little battery life, and overall just not being that great. Two motors each are mounted in a push/pull configuration inside a 5×5 array of 3d printed ducts. has taken a paraglider, which is essentially a non-rigid fabric wing that to the untrained eye resembles a parachute, and powered it with fifty drone motors taken from other projects. Was it a success? Eh… mostly.Īs even says in the video: Don’t try this at home. If there’s one thing you can count on for, it’s for defining the the aviation category of “Don’t Try This At Home.” In the video below the break, displays his latest terror of the skies: A powered paraglider backpack that has fifty electric motors. This time he started from scratch and ran into even more problems!Ĭontinue reading “Autogyro Models Are Hard - Even For ” → Posted in hardware, Transportation Hacks Tagged autogyro, Gyrocopter, gyroplane, peter sripol, R/C, radio control, rc He’s built a few in the past, with limited success. This isn’t first attempt with autogyro models. So it made sense to build a model to help learn to fly. recently got his hands on a full-scale autogyro. The blades freewheel, spun by the air as the craft moves forward. Autogyro rotors aren’t powered during flight. Lift for autogyros comes in the form of a rotating set of blades, much like a helicopter. That’s where the similarities end though. They also have a tail section that works similar to a fixed-wing aircraft. Aviation master has dipped his toes into the autogyro world, but not without some trouble.Īutogyros are propelled by a propeller, like a plane. People who like vehicles that blend the best (or worst) of both airplanes and helicopters. The two groups rarely get along, each extolling the virtues of their chosen craft. Airplane enthusiasts, and helicopter enthusiasts.
