Great summary and thank you for putting it together. Plenty of starting points for further research. My hope is that SS batteries will one day break out, meeting some of their earlier promises of capacity/weight, time to charge, safety improvements etc. Interesting too that H2 is progressing as well as it is - will be looking closer at it for energy storage in our house in the next few years. Big thank you once again from Sydney - David
@@ElectricAviation have you seen the new MIT invention the Toroidal propeller it is supposed to be quieter and more efficient so the question is can it be used in VTOL aircraft the article is in MIT Lincoln lab
Excellent summary, thank you very much. Can I ask to include hybrid type vehicles like Jetoptera which uses a gas turbine to generate electricity and a very interesting propulsion system. I know you've covered them in the past but I think it's still a decent bet compared to the consensus lift drive systems of Joby, Lillium ,Archer etc. Personally I don't think 5 seaters cut the mustard for most commercial applications.
Piasecki is pronounced pie uh SECK ee. Piasecki Helicopter was building dual-rotor helicopters back during the Korean War era. When the founder, Frank Piasecki, was pushed out in 1956, the company became Vertol, which was acquired by Boeing and their main product, today, is the Boeing-Vertol CH-47 Chinook. He focused on dual-rotor choppers because tail rotors add drag and eat power, whereas eliminating the need for one provides greater lift : power and higher speeds. The Chinook is one of the faster, heavy-lift choppers out there so ... he's right on that count. Frank Piasecki went on to found Piasecki Aircraft, which is making one of the the slow-rotor compound helicopters. He designed a variety of concept aircraft, back in the day; he has a long history of making interesting, and somewhat unconventional, rotorcraft.
Sorry I try my best and always get it wrong. Believe it or not I had the google pronunciation tool read me out Piasecki when I was doing the voice over. Anyway thanks for your informative comment
Good comparising, I would like to know what is the most silent V-tol? Because I think when it,s operating in a urban inviroment it could be a game breaker.
hey what do you guys think about using ion propulsion on the main rotor of a gyrocopter to increase the efficiency and low speed performance? the better boundary layer retention would do a lot for their rotors efficiency, by powering the main rotor you could get some seriously STOL, and without all the weight overhead from needing all that VTOL thrust
If only they can make the Ion propulsion more efficient. I do think it has a lot of potential if coupled with other technologies. Your idea needs to be explored. Its food for thought
No mention of EHANG out of China. EHANG is less sophisticated than others but is further along the certification process and has sales already. ENANG has infrastructure and operational control already in a working state. It has agreements in South Korea and Japan and is widely known in Europe. Not a single mention?

could you make more Green H2/ Fuel Cell videos please?
Sure. I work for a company that is making fuel cell for one aircraft
@@ElectricAviation Thank you.

@@ilyakosarev thx. i am looking for tech. details of FC/H2 combinations.

How much % of increase in H2 fuel cells conversion efficiency can we expect in the next few years ? And what about metal - air batteries ?
Great video... very informative, for those of us closely following this industry.... Keep up the great work!
👍👍
I think batteries are the biggest hurtle at the moment.
Cheers

Seems like one of Joby’s selling points is its low noise level
As always,
Thank you so much for a great video
Thanks again!
The Piasecki compound chopper is the only one you'd feel good about dropping you into a hot LZ. All the rest are so fragile looking.
I suppose Electric Aviation needs to do half yearly updates since they are developing rapidly, i presume!

What are your thoughts on toroidial propellers?
No mention of EHANG out of China. EHANG is less sophisticated than others but is further along the certification process and has sales already. ENANG has infrastructure and operational control already in a working state. It has agreements in South Korea and Japan and is widely known in Europe. Not a single mention?
I have covered EHang in several other videos
Very good documentation.
Archer is going to lead this market.
It seems so. I am still baffled by the resources they have
What is happening with Jetoptera ?
Last I heard they won a contract from US Airforce.
thanks
