Gas emittance... the internal seat probably rotates for directional aiming of the gas source and this augmentation is safely and effectively achieved. I am assuming the Scandinavian version will be released first due to pre existing language alignment - in this scenario all that the unit requires is a red occupant activated button that says "FART" or "FARTING"... The OH needs only to confer this... One would need to be prepared to learn at the minimum a couple of words in Dansk or Svensk, or even Nordsk to become a capable and intensive user... There should be a practice exam section in the rear of the OH with useful pre-exam revision "you say the word" questions such as; "I am ....ing my way around to you now" or "I will .... to work this morning".... but these questions may be in a scandinavian language as opposed to english presented here.

I think the cooling fan is bigger than you need.. Shy Cancel will never approve that. THEY are the only ones allowed to take people for a ride and they do it in SLOW motions.. Nev2 points

Actually nev they do, in the same way a helicopter's rotor does (A helicopter in forward flight uses less power to maintain height than it needs to do the same in the hover)2 points

I bet that was some ride, before all the banging and jerking and bouncing stopped!! It says a lot for modern aircraft design that all got out virtually unscathed, and there was no fire. It also speaks volumes for airport design to have a relatively unobstructed overrun area, so that airframes can survive overruns relatively intact - unlike many airports where huge ditches, a vast amount of urban infrastructure - and even ravines - are where aircraft end up, after overruns.2 points

I do not care if the fuel burn is down to piston engines ... the AU$114,000 purchase price means this is NOT an engine for an ultralight ... in fact its nearly twice the cost of the jet on the Sonex. And the difference is $$ between that and a Rotax 912 or a Jabiru pays for a lot of petrol and maitnenance. This engine due to price tag is targeting military drone customers and high end experimental where the owner is unconcerned with $$ and just want the kudos of a tubine up front.2 points

Interesting how they see this thing being used. I like how the ambulance one drops off two paramedics who work on the injured person for a bit then slide her into the craft and send it off with only her on board. Who maintains her vitals on the way??1 point

I'll believe it when I see one operating in gusty conditions, The only way to get extra lift is to increase rotor speed. Too much lag in that to give precise control.1 point

Marty, it looks like they use a sort of "wobble drive" universal-joint setup in the driveshaft. This system simply tilts the rotors. They claim they're aiming for maximum simplicity and the minimum number of parts/components to stay aloft safely. Their cruise speed is a reputed 130kmh, and probably the interesting part is they are claiming "automatic flight", rather than "autonomous flight". They say that it will be many years before totally autonomous flight is possible and achievable, thus they're concentrating on automatic flight, using fixed flight paths, and pre-designated take-off and landing areas. This seems to indicate remote control of these e-copters. It looks like they're aiming at inner-city air-taxi type operations and cargo deliveries. https://www.flynow-aviation.com/1 point

I read somewhere on the white paper that it really is equipped with FLIES (Flys Like It Embodies Shit) anti collision safety features... can anybody confirm this? Have any further defications been provided yet? ๐ค1 point

I was giving you a simple example so it's easy to visualise. The one at the show I mentioned was trying to climb from memory a grade around 5%. If you don't need to follow ground contours, no problem, just climb vertically then go over the top of the hill.1 point

That's not hard to work out, but the fans don't get aerodynamic advantage going sideways. Nev1 point

No horizontal thrust. Nothing wrong with that design in still air but if a wind comes up it will go with the wind like all the others. A drone climbs by increasing speed of motors; let's say you want to fly up a long slope in the mountains, say a 45 degree slope; if you tilt the nose up like you do with an aircraft, your directional thrust moves you backwards out into space; if you tilt the nose down the optimum climb is at 45 degrees with your nose pointing to the ground. There's a video on this site of a pilot at a show not prepared to do that and even at full throttle was sliding backwards.1 point

I'd suggest it would likely break your neck. Who's going to accept the restrains necessary? The more you look at this stuff, the more problems you'll find. Nev1 point

In fact it still might be a problem when they slow the flip enough for the g forces to suit humans, but the programming is already there if it' knocked upside down to flip it and lower the drone to earth.1 point

That would give the Passengers a thrill. 120 RPM? It won't rotate about it's own centre of gravity either. They are a contraption using non tilting thrust fans. Nev1 point

They have the programming to do a 360 degree flip in about half a second, thatโs not a problem, they just donโt have 100% forward thrust.1 point

Regarding craft stability in winds and gusts, the level of stability sensors and software on even the most basic drone is far ahead of anything in the GA world and control response times and correction inputs are far ahead of most human ability. It depends upon type of flight controller and array of sensors that are employed; without them the craft is uncontrollable and unstable. To put things in perspective, an industrial level drone will have triple layer isolated redundancy for its main frame and generally minimum dual redundancy on GNSS, Lidar, Infrared, Ultrasonic Sensors, Baro, Airspeed, Gyro, Magnometer, 5G Video Broadcast to name a few Add ADSB in/out or FLARM to that platform and throw a big lump of live meat into the scene there is little for the human to actually do other than push a button for "Destination" and enjoy the view, or freak out at which point they can press "Panic" and the craft will land and the live meat sack can spew their guts out on the ground. I am doubtful we will see these craft buzzing around. They will be fairly limited in range until micro nuclear batteries are made available, outlandishly loud and intrusive; more so than a jetski; and the risk assessment attached will just not be acceptable to insurance companies without super high premium costs. And to be really honest there is just no use case for them when it comes to human centric transport. Finally how will the aviation bureaucrat deal with "big drones" being used by terrorists to carry out fresh forays into activities aimed at bolstering their social media channels and staunchly defended acceptance on university campuses? Sorry gone off topic again... let's refocus and wind things up with a conclusion.... "It will be fun" "Human Factor" push one of two buttons; that will be where the administration, insurance companies, and lawyers will have to arrive.1 point

The ones I've seen have stalled at the findamentals; a little like the disappearance of the hovercraft we used to see travelling around on trailers and the drying up of dialogue about drones. They can get off the ground and some even have motor redundancy to retain balance if one or two motors fail, but they can't handle winds.1 point

Most pilot's find a simulator harder to fly than the real thing. People who fly simulators a lot know how to trick the thing and "Play the GAME" as it's called. Nev1 point

Reverse thrust is most effective at high speed. If the spoilers didn't deploy and the runway was wet, that would explain the lack of retardation, With a heavy landing the springboard effect on a long fuselage could have injured the Pilots .I had my back injured when in the Jumpseat of an A-300 600 R.

The fuselage is intact although well damaged. The "other Brand " usually breaks up into 3 sections.. Some weather conditions are beyond safe. Planes are expected tp fly 24/7 We take many things for granted. Nev1 point

There's a good story on the ABC where QANTAS have only recently discovered a can containing a short 9 minute film from 1939, about the QANTAS Empire Flying Boat service from Australia to Singapore. https://www.abc.net.au/news/2020-11-15/qantas-celebrates-centenary-with-bygone-era-flying-boat-film/12881604 What is unusual about the film is, it's in colour, but it's silent. Colour film was very rare and expensive in the period before WW2 - it was WW2 that finally made colour film less expensive - but even then, it's only in the last couple of years of WW2 that colour film (of the War) started to appear. Here's another good site with a comprehensive story about the Qantas Empire Flying Boats. You'd have had to be wealthy to afford a seat on one of these luxurious aircraft. The detailed ad showing the fine points of the Empire Flying Boat is fascinating. They even had a separate smoking room! https://www.executivetraveller.com/the-way-it-was-sydney-to-singapore-in-4-days-by-qantas-flying-boat1 point
