I'm impressed he got the thing to fly far enough to land in a corn field.

He was a software developer, I assume he's back to doing that.

Jim Bede was at least using known physics, whereas the Raptor appears to have been designed in dreamland.

Peter had modelled the Raptor in the CFD module of Solidworks, but running a few basic calcs indicated it was well disconnected from reality.

I suspect he had a poor grasp of the need for accuracy of the input parameters, such as fluid properties, across the entire operating range. The lift/drag polar of the airfoil section in CFD was likely based on the flow being laminar for a long way from the leading edge. The actual transition to turbulent would have been further forward.

I often run into that issue my young engineers who blindly use engineering software. They usually fail to understand that the softare defaults need to be understood, rather than ignoring and hoping for the best.

I hope Phil C. has some views he could share on this.


Simon, are you back down under? But yes....I am working with a bit of this now in a RV10 upgrade world. Even old heads get sucked in by the "this is CFD, it should be right...... :eek: :rofl:

We should catch up for beers some day :cheers:

Not yet. We are currently packing, and will be flying home starting on December 17.
The last 10 years has gone so quickly. The young kids I brought over are going back as young men. The youngest has spent most of his life here, and has a full Canadian accent.
Great idea :cheers:
