Towerman April 27, 2020 06:02 AM Interesting, something different but not in an over the top way, this could fill a potential niche in the general multicopter field. (a quick get away from the concrete city life) out to the open outskirts for a weekend camp. And then back in a whizz when the weekend expires. I love the idea of a gimbaled Cabin as Loz pointed out (so would be great if this come to fruition), but first let us see some trial flights, and i like the shape and looks of the Cabin on this Atlas. Keep it up i expect to see good progress !BTW Loz, could you try to perhaps contact the guys at Skai for a follow up review, i would really like to get some fresh updates on that machine also. It's been a very long time. guzmanchinky April 27, 2020 09:33 AM Cool new design, I like how it easily transitions to winged flight, unlike a quadcopter. paul314 April 27, 2020 10:24 AM So if there's recharging at the other end, that's 200km of range. Of course with one person plus minimal luggage the applications are restricted somewhat. Thud April 27, 2020 05:43 PM Something doesn't add up. How does it weigh 285lbs and carry a battery 1/4 the size of a Tesla battery? Model S batteries weigh almost a ton. Thud April 27, 2020 05:44 PM Sorry they weigh about 1,000lbs. Still doesn't add up. Howie April 27, 2020 11:26 PM One way to make ballistic parachutes safe is for the FAA to mandate that landings and take offs must have an attendant 300 foot precipitous drop. This means only tall building roof tops or a cliff edge landing zone. An approach would then transition from a safe 300 feet to an immediate survivable 10 feet or so, if the craft lost control or power either on approach or right at the pad. This limitation for landing pads would then mean there is no death zone. Towerman April 28, 2020 04:23 AM @ HowieIndeed, Indeed. In addition to your suggestion, there are more options ! If certifying is the only thing holding it back, make take off's over water and approaches to landing over water mandatory. Both your option and this one would be enough for the regulations to approve of these machines, i really really cannot see why not ???!Now that there's no more excuses, let's get them up in the air already ! Tris April 28, 2020 09:22 AM @Howie, With a dead engine the need to keep wings lifting with minimum lift speed into a horizontal landing is far better without all the drag from stalled fan props that steepen a decent angle or increase impact speed. Ballistics are a bad option as inefficient weight carried with no value at the dominant sort altitudes. You’ll see in the SkyDrive eVTOL thread what is far better using Electric Propulsion without dangerous parts.@Thud, You are so right that things don't add up. They specify a 2 hour recharge. At 220 volts and 50 amps, a typical stove outlet, it could supply 22kWh of energy in two hours. Tesla batteries store about 250 Wh/kg so the battery would weigh 88 kg or 196 pounds. Obviously battery weight is not included in the figures given.@Towerman, The Watfly is an interesting design but as we discussed earlier in the comments on the SkyDrive from the pictures it looks like it is an efficient body part eliminator in that judging from the height of the man in the pod it looks like he is taller than the top of the engines on the ground. Also, who has $150,000 for this toy for the rich? Tris April 28, 2020 09:22 AM @guzmanchinky, Looks can be deceiving. A major problem with tail-sitters is controllability at zero airspeed and it looks like the Atlas may suffer the same problem due to the lack of four corner vertical thrusters. In analyzing the forces on the vehicle imagine the vehicle pitched slightly from vertical. The thrust vector of the engines will be through the center of gravity thus the engines produce no torque on the aircraft and can't right the vehicle. From the pictures, is pitch controlled by moving the entire wing or are there control surfaces at the trailing edge of the wing that will have the ability to rotate the vehicle. Maximum force will be when the controls are at 45 degrees and it is unlikely that you can move the control surfaces to 45 degrees in under a second. This time delay is what limits the range over which the vehicle can right itself. Stabilizing in a micro second vs a fraction will remove the Atlas eVTOL advantage of a smooth flight as AIP would be by far much better. Towerman April 29, 2020 11:59 PM I take into account what you say Tris, it's a good analysis. However i say the concept looks good as a starting point.Let them build a prototype, test, update and tweak it from there, it's not to say the end product will look exactly like the starting product.They simply need to take the limitations seriously, (which i believe they will, either via testing a prototype) Or brainstorming the attributes that would make it not work. Looking at data or past experiences of others etc...Once they figured it out, changed variables, gone through a few prototypes, tested it extensively, the product can be tweaked to perfection.
