New Avialicopter thingamabob...

[Coligny]

Collision between an helo and a plane, as seen in the AH56A Cheyenne from sykorsky in the 60'

This thing could have been designed by Badi Dea Corp (transportation beyond imagination).

The propellers just beside the access doors take the cake as far as really bad ideas goes.

Also chexk the vibration on the right pod, something seems to have been hammered a little too approximatively for a high speed rotating assembly... (nothing that a littul duck tape would fix...).

Unlike the V22 and all it's prototype since... well... the dinosaurs... It's fly doesn't end up most of the time in a fiery fireball, making it re-usable, quite a new concept it seems...


(V22 sort of kinda like planes started being tested before I wuz born in the 70', I forgot aboot them in the 80' and wondered if they will be reliable enough to enter service in my lifetime since the 90'... ok, they entered active service... but I'm not quite sure aboot the reliability part...).

As a pototype, it'll have a few kinks to work out... it's the purpose of a prototype.

From my understanding he refers to the place this aircraft would sit is in search and rescue opperations, where speed is vital, with a VTOL setup... While current helicopters are sufficient for close range rescues, long range it falls severely short of capability.

The props near the doors are a non issue. There's no less clearence there then what is seen in a normal multi prop aircraft.

In addition, so long as one engine is shut down, the other can still provide anti-torquing ability to the airframe.
(edit: We'll wait and see how stable it is when it comes up to the tests for single engine shutdown use).

I think it's a good design, significantly more stable then most of what's been tested in recent years.

useless comparison... you don't try to lower a diver and lift up distressed people while stationnary in mid air during a rainstorm with prop plane...

As for the torque control... Kamov got a better solution that would fit perfectly at high speed, with coaxial you just discount the retreating blade lift since you got one going the right way on the other rotor...

Duct or Duck tape, it works both ways.

I am quite sure that most people think it is "duck" tape and not "duct" tape as many people dont use "duct" tape for it's named purpose...

It is ok coligny... you helped edumacate many people with this... many people.

The Brits already tried that more than 50 years ago, it didn't work out....

But perhaps with modern fly-by-wire controls it will be a bit easier and safer to fly a thingamabob like this, who knows. I like the idea of a high-speed helicopter, but I think the Americans have the right idea:

I just wish all things not "working out" would be like the Fairey Rotodyne.

Meanwhile for others, "not working out" look more like this:

The V22 is possibly the biggest boondoggle ever to get airborne. It's ineffective for what it was designed to do, and too expensive, impractical and unsafe for what it can do compared for example to a C-27 Spartan. And it's only taken like what... 20-odd years to get from prototype to deployment?

Worse than the Pogo? That is hard to believe.

It took them only 5 years to figure out the Pogo was a failure, they still haven't done so for the V-22, even though the program has been running for almost 30 years. The only reason I can see why anyone would keep pouring money into this bottomless pit is to use it as a stepping stone for larger and heavier tilt-rotor aircraft that might be more effective. Luckily, they are doing just that.

Based on V-22 technology, it should have the same payload capacity as a C-130 Hercules, but VTOL capability. Now we're talking.

oh dear... take a bad idea, double it and pray it works... i hope they stocked on spare parts for those CH53, cause they might not have the luxury of being retired anytime soon...

What makes a truly 'successful' boondoggle is that it show just enough promise of success to encourage people that it is still worth throwing time and money at it.

You know what 2 pogo and a bodyshell in between are called ?

a V22...
