It'll be interesting to see how it develops...

Looks looks like a prop with a big heavy skirt. The prop would probably lift more without the skirt. I don't see how the coanda effect provides an usefull purpose as the downwash is already straight down from the start. The skirt just adds skin friction.

Good enough for grant money though!:=

well again the same thing
british invention with little or no backing from the goverment , what will happen next i . lets think , a clever man from the usa will say i will give you big cash to develop it and after that when a new use is developed the uk will buy it back and have to pay over the odds for the rights to do so ,
rember the jet engine ????????

Well, this explain why the development of the R88 has gone slow; Capt. Hollywood has been developing this in his spare time.

There's me with a full order book and some already dissatisfied customers wanting to take delivery of their R88 - but at least I know where to find him now and I'm sure the R88 will be back on track.

and a lot of Hydro Electric plants, that is!
Looks just like the toy my MiL gave my son for Christmas and like the 'vehicles' in the vid, can only be flown inside without disastrous flight patterns!

"If it hits a wall, it wouldn't crash".......OK!!!
In the 'toy', torque kicks in, inverts it and it then powers itself into the ground!

By the way, by following the link on vid page you can get the companies list of 34 applications for the vehicles, ranging from Mountain Rescue to Laser Target Designation.
Realistically , IMHO, the only one of the 34 that is going to come to fruition will be that application 2nd to last in the list....."Toy"!

What's it like in autorotation?

"There is nothing like it in the world." It really pisses me off when people go on about how great their invention is without really saying why. Why is a single fan using the coanda effect and mechanical flaps so much better than say, 3 small, ducted, fixed pitched fans? At that size, the latter seems like a better solution as the mechanics are incredibly simple and won't get blowing about by the wind so much.

SilsoeSid: I'm sure they will find plenty of uses for it if it ends up being as cost effective and practical as an RC heli -- some people are making a living off RC aerial photography alone.

rember the jet engine ????????
bauldrik,
I was thinking this was exactly the same thing as the jet engine thing. Same technology class and everything! Jet engines will probably be obsolete once P&W gets the rights to it!:)

Hmmm. Look familiar?:confused:
