At least we can tell it's from an English-speaking country.

Yes it does, but I am not telling which, a clue however, note what appears to be a cyclic control??

Hmmmm, is it the Lockheed XV-4B?

On the right track Harry, but this aircraft had only five engines??

Yes, I noticed the cyclic. Also the label "Lift Engine" on the cyclic housing. (And "Lift Prop" on the left.)

I'm going to go with the Ryan XV-5.

As I said above this aircraft has FIVE engines ??

"Flew for over ten years, providing a great deal of data that influenced later design concepts such as the "puffer jet" controls on the ?????"

"was the first #&*%#@$% fixed-wing vertical take-off and landing aeroplane."

Short SC.1 ?
I thought it might be the Avrocar, but that didn't add up so I cheated with google, so I am not claiming a win.
