Title: True door to door transport Post by: BerkshireBugsy on August 01, 2015, 11:36:25 I didn't know if I should post this here or in "the lighter side" :)
I found this on the Top Gear web site .... https://youtu.be/wHJTZ7k0BXU (https://youtu.be/wHJTZ7k0BXU) To quote one of my fave films "Roads? Where we're going we don't need roads!"

That will do wonders for the energy usage of transport!

That will do wonders for the energy usage of transport! As I read it that's only needed for take-off - and landing. And that sounds scary, as I doubt that those little propellers would provide much lift force in auto-rotation. So if the batteries run out when you are in the air, a VTOL landing is going to be distinctly brick-like. I guess there is a possibility of landing as a gliding aeroplane, if you (or the control software) has the training and if there is a suitable runway.

Title: Re: True door to door transport Post by: JayMac on August 01, 2015, 15:01:05 Auto-rotation ability was my concern as well. The propellers look insufficient to achieve that.
Production tilt rotor aircraft, such as the Augusta Westland AW609 (currently still at prototype testing stage) must have auto-rotation capability before they will be certified for civil aviation. The AW609 successfully completed FAA monitored auto-rotation tests in late 2014.

I like the phrase distributed electrical system ....................... mmmmmmmm there are not too many electrical systems I've come across that aren't distributed in some form or another Title: Re: True door to door transport Post by: Chris from Nailsea on August 01, 2015, 22:22:40 So if the batteries run out when you are in the air, a VTOL landing is going to be distinctly brick-like.

I'm not convinced: there seems to be very little wing surface to allow for such unpowered gliding to a suitable landing place ... :-\ Title: Re: True door to door transport Post by: BerkshireBugsy on August 02, 2015, 07:44:39 Some interesting observations guys but crazy ideas have to start somewhere.
Imagine trying to convince George Stephenson (sp?) that one day trains would be developed which could float above tracks and travel at speeds in excess of 200 mph Title: Re: True door to door transport Post by: Red Squirrel on August 03, 2015, 23:54:20 Imagine trying to convince George Stephenson (sp?) that one day trains would be developed which could float above tracks and travel at speeds in excess of 200 mph Imagine trying to convince someone waiting at West Drayton in the morning that one day trains would be developed which could float above tracks and travel at speeds in excess of 200 mph...
