That said, we’d love a chance to ride the Flyboard Air – after a few hours of training on the original Flyboard of course.Ĭontinue reading “Hoverboards Are Here – If You’re Crazy Enough To Try” → Posted in Slider, Transportation Hacks Tagged Flyboard Air, Green Goblin Glider, hoverboard Is it practical or safe? Heck no! Nor is it cheap – those engines cost €8,845.00 each. The metal doesn’t reflect enough thrust to cause the Flyboard to become unstable or stall. If you watch closely, he takes off and lands from a perforated metal platform mounted off the back of a van. solution is not never get too close to the ground. These are problems faced by the harrier jump jet and the joint strike fighter. Engines can suck in their own exhaust, stalling them. One final thought – taking off and landing a jet vertically is difficult. The two electric ducted fans on the sides of the Flyboard Air appear to be running all the time, only shutting down when lands the board. We’re betting that the only electronics are the remote throttle control and the Engine Control Computers (ECU) needed to keep the jets running and synchronized. Such a skilled rider means that control wouldn’t really be needed on the board. With that much skill under his belt, would have no problem keeping balanced on four jet engines. Loops, spins, and other aerobatics look easy. There are plenty of videos on YouTube channel showing the amount of control a skilled ride has over the board. These boards have become tremendously popular at vacation spots in the last few years. His previous invention, the Flyboard uses a personal watercraft to create a column of thrust which the rider stands on. As it turns out, is one of the world’s most experienced thrust riders. Standing on a column of uncontrolled thrust would take quite a bit of skill on the part of the pilot. Accelerating 3 or 4 pounds metal from 78,000 RPM (~70% throttle) to 98,000 RPM (~100 % throttle) takes time. Turbines however, have throttle lag on the order of seconds. Quadcopters have this with their brushless motors. Active stability in a fixed pitch rotary blade system requires very fast throttle response. The problem boils down to the physics of jet engines. Why no built-in intelligence? Even the smallest quadcopters have gyros, accellerometers, and PID loops keeping them upright. ![]() That’s plenty to lift, the board, and a few gallons of Jet-A strapped to his back. Four of those engines would provide 352 lbs of thrust. We don’t know exactly which engines is using, but as an example, the Jet-Cat P 400 RX-G packs 88 lbs of thrust into a shell less than 6 inches in diameter, weighing less than 8 lbs. These jets look quite a bit like model aircraft jet engines. stopping the action shows a split second where four exhaust holes are visible on the bottom of the board. At the end of the video, flies over the camera. Between his sneakers we can see two round openings – which look a lot like jet intakes. During the video, looks down at his board and the water below. A hand controller simply provides throttle to adjust altitude, take off, and land. ![]() ![]() Balance, stability and control are all handled by the pilot. Here’s our hypothesis: Flyboard Air is a jet powered platform with little or no built-in intelligence. Details are few and far between, so much of the information in this article is educated guessing based upon the video. After a few back of the napkin calculations though, we’re coming out to say we think it’s real. Plenty of folks are calling the video a fake. The video depicts pilot taking off, flying around, and landing an a platform not much larger than a milk crate. It shows a test of the Flyboard Air, a device that is somewhere between a Back to the Future Hoverboard and Green Goblin’s glider. A new video has been stirring questions on the internet this week.
