Windrunner: Why there won’t be a scale prototype for the world’s biggest aircraft​

The company developing what is set to be by far the biggest aircraft the world has ever seen - the Windrunner - will not fly a scale prototype. Radia CEO, Mark Lundstrom, explains why in a wide-ranging interview with AGN on the sidelines of the Paris Air Show.

If they're still talking about unimproved runways near the wind turbine areas, the design would be much better served with turboprops than fans. So that wing with 4x A400 engines per side, maybe even 6x per side.

Might go against the ethos of using only 'off the shelf' proven components.
 
Might be the right approach for the prototype, Stratolaunch did that too, at least to a certain degree...
 
A400 engines are proven. You just need more of them.

Or are you/they meaning "parts we pulled out of the Boneyard"?
Even though the engines are all proven and certified, using more than 4 will mean changes to the cockpit controls etc that call for more risk assessment and certifion. Then the fuel system with more permutations of 'tank to engine' feeds.

So talk to whoever is doing the B-52 8-engine FADEC cockpit interface design and "acquire" a set, then install the prop controls.

Turbofans are distinctly suboptimal for dirt runway operations.
 
I'm not disagreeing with your logic, just suggesting Radia will go with a sub-optimal solution as being easier to get flying. I've worked on enough projects where obviously good proposals were squashed by the cost of getting approval.
It's just that the turbofans are so bad for dirt strips and anything approximating STOL performance...

And refitting the wing for props-at-wing-level versus podded-jets is a major redesign, so if you don't do it at Prototype it'll never happen at all.
