The most disruptive moment ever for rotor craft industry?
 
Could this be the press statement with news of the begining of the most disruptive period in the history of rotary?
Brazilian airline "orders" 220 liliums and talks of a potential requirement for 1000...

In a video interview, interesting and pertinent comments by Azul Airlines CEO, noting how Lilium will integrate into Brazil's helicopter market.

Short video on lilium Facebook page of approach and landing of their latest test platform. Not much new to see, the craft does not feature the landing gear on the full scale mockup nor the straight edged engine nacelles. Engines still have trendy serrated outflow.

There's a sucker born every minute! Better cash out early before that stock tanks!

According to Engle, USD 4.5m per aircraft (if you buy over 200)

30 minute, 100% fast charge turnaround
 
Charging spec is shuttle friendly. Marketing funding in place, they just need to build and fly a full scale aircraft. :)
"We’re excited to announce plans for ABB to provide fast-charging infrastructure for our high-speed regional air network — helping us deliver the quick turnaround times needed for electric aviation. The charging points are designed to fully charge batteries in approximately 30 minutes and up to 80% in 15 minutes."

21 September Bristow announced it would be buying up to 50 Vertical Aerospace VA-X4 e VTOLs.

I'm still curious how they intend to meet certain FAA rules......

§ 91.151 Fuel requirements for flight in VFR conditions.(a) No person may begin a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed -

(1) During the day, to fly after that for at least 30 minutes; or

(2) At night, to fly after that for at least 45 minutes.

(b) No person may begin a flight in a rotorcraft under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed, to fly after that for at least 20 minutes.

Powered Lift category is not mentioned in that FAR

What is going to be the target passenger? People going to the airport? Coming from the airport? Let's look at these 2 first.

Travellers will have baggage. Doesn't look like much room for bags on Lili. "Oh, we are aiming at business travellers, just taking a briefcase for a meeting." Straight away the potential list of passengers is slashed, particularly in Oz, where the customer Lilies into Sydney, gets a taxi to the Quaintas terminal, but then waits for 2 hours, flies to Melbourne for 1.5 hrs, taxi into town, wait, go to the meeting, wait, taxi back to airport, wait 2 hours, fly for 1.5 hrs, go back to Lily Pad - long day.

And then, where does Lili take you (within 30 mins)? It won't be to the street outside your house. It won't be to the sports field 1km from home, the council won't allow that, and then you need another taxi to get home. It won't be to the rooftop terminal for your suburb, it doesn't (and won't) exist.

Dreamers. Take your money, spend some of it on great CGI, pocket the rest.

Fair enough, but where is it mentioned? I've looked for FAA fuel requirements for powered lift and failed to find any. Do you have a link?

Powered Lift was added as an aircraft Category in 1997. Maybe they just forgot to update the fuel requirements, as there were no non-military types at that time. Shhhh....

They won’t have to. A brand new set of bespoke requirements is being written specifically for EVTOL devices.

Yep… not a big “believer” yet either, in any of the eVTOL other than being “toys for the rich” maybe… But even then: The building of a craft really is the “easy” part…. But then what do you really do with it? How? Under what rules? Etc etc…

Maybe councils in the UK won't allow that. I once landed an R-22 in my backyard during training, so I think a Lilli would fit.

Times change, I have landed LongRangers and Squirrels in (big) backyards to pick up rich dudes, but that was in the 90s in Sydney. Don't think we would get away with it these days. And when operating police choppers in the 80s we could plop onto any sports field if the requirement was there, with an agreement from all the local councils.

Statements that CA$A is onside and "working" on a solution for Lili Pads across Melbourne make me laugh, CA$A is hard pressed enough to cope with the normal regulatory processes without spending time on the CGI daydreams.

Bwahahhahahahhahaah CA$A couldn't arrange a bunk-up in a brothel with $100 hanging out of each ear. They still haven't fixed the fur lined ocean going balls up that was the part 61 implementation from Sept 2014!

Oct 2021 test flight of the gen 5 vehicle.
Looks like a calm day.
Still no transition from high speed flight to a hover. The transition in this flight, from 40kph to hover is smooth.

There seems to be a new boy on the block:

nceptivemind.com/cityhawk-worlds-first-wingless-compact-evtol-aircraft-moves-step-closer-reality/21212/?fbclid=IwAR3RLz4TKohuIfLPxyMsBPsRVUWEDIBvJ-cRRX_J9SQr2lr8L95qkFAd694"Urban Aeronautics, the Israel-based aerospace company behind the world’s first compact, wingless electric vertical takeoff, and landing (eVTOL) vehicle, is getting closer to turning its groundbreaking concept into reality. The company said it has raised the first $10 million of a $100 million funding round this week towards CityHawk from private investors in the US, Brazil, and Israel.

According to the company, the car-sized, six-seater CityHawk has more in common with birds than with nearly every other eVTOL prototype in existence. With a distinct, wingless exterior and patented fully-enclosed Fancraft rotor system, the CityHawk is mainly designed for commercial air charters and emergency medical services (EMS). It will be fueled by hydrogen, the most sustainable technology in development today. This means it must be able to conduct multiple trips within a city per day with zero emissions and minimal noise.

An innovative Fancraft technology is based on dual enclosed, ducted rotors with a variable pitch for thrust control, which enable uncompromised stability even in strong winds and turbulence during takeoff, hovering, and landing. The enclosed structure also results in minimal noise, both inside the cabin and outside.


The compact eVTOL also incorporates autonomous systems able to detect and avoid oncoming traffic, power lines, and other structures along the route. Besides, the multi-spectral see-through weather detection and anti-icing capabilities enable the VTOL to fly safely at night, in inclement weather, and in degraded visibility conditions.

In addition, the compact design makes it possible to land CityHawk at your block’s rooftop vertiport to save an hour by flying over traffic, especially in case of emergencies. Inside, the CityHawk has all the perks of a luxury car with comfortable seats, Wi-Fi, and touchscreens, plus a view of your city from above.

The company recently announced the partnership with California-based Hypoint to adapt hydrogen-fuel-cell technology for aviation. The redesigned hydrogen-powered version of its CityHawk eVTOL aircraft replaces its current Safran Arriel turboshaft engine with a propulsion system based on HyPoint’s cutting-edge hydrogen fuel cells."

Geez, on a 30-minute flight with amazing views, the milennials still want wifi. And of course, your block has a roof-top heliport, doesn't everybody's?

Less Hair 29th Nov 2021 03:06

Will the noise and the blast when hovering make it acceptable for inner city and metro area flight operations?
