That sort of dogs' tooth notch is quite common on swept wings because it reduces spanwise airflow along the leading edge. It reduces the risk of a wing root stall continuing all the way out to wing tips. Because wing tips are behind the centre of gravity, they produce a positive pitching moment (nose down) that helps with stall recovery.Wow, look at that step/droop in the leading edge just outboard of the main gear!
No way, this is a unique, stand alone aircraft. It shares very little in common with those others, other than being a delta planform.Dear moderators,
Please merge this thread with the other thread about small deltas: Dyke Delta, Delta Kitten, Facetmobile, Hustler, Verhees Delta, etc.
This would be an absolute winner as a kit
It's one of my favorite aircraft. It looks modern. The tandem would be awesome as long as you kick up the rear seat a smidge for visibility.One very unique feature, is that the fan was designed to use engines spinning at 4000 rpm. That opens the door for a large range of today's automotive engines direct drive (read cheap) that weren't available in the early 1970s.
I have a simple 3D of the Rohr, and a few of my own 'easy to construct' iterations...

I have also found Don Westergren, part designer and test pilot of it, hoping to ask him some questions.
There were models tested with skis in floatplane style. No joke.? Don't understand.
Early in the program somebody realized that the plane was capable of floating on its sealed, foam-filled wing. Tests with scale models showed that the airplane could take-off and land on water with the help of hydro-skis. This opened up the possibility of snow landings as well. With retractable skis, the Two-l75 would certainly have had the cleanest seaplane configuration ever seen.
To me aluminum just makes the parts count and build time soar...Only aluminium for me.
Got to figure this one out, worth doing as it solves the engine issue, and that's half the plane.
Well I am proving at the moment that's no where near as bad as some imagine, and I can't change that I am comfortable with metals, and that everything for metal working is within a stone's throw from me.To me aluminum just makes the parts count and build time soar...
