Way back in 1979 a UK company designed and built a similar aircraft. The Edgley Optica was aimed at becoming an airborne observation platform, primarily for UK police forces. Having a longer endurance in the air, and greatly reduced operating costs than a helicopter, the concept appeared viable. Unfortunately the acceptance of the aircraft was far less enthusiastic, and the company folded.
@MattH-wg7ou In a typical piston engined aircraft the rotating propeller produces a yaw effect, especially at full power. This requires more rudder input at take off. Jets track straight. Originally this aircraft was to have a piston engine. They are cheaper to buy and operate than a turbine engine.
Ducted fan. The British developed an aircraft of this type back in the 80's, but sadly there were a couple of crashes, which if I recall correctly were not down to the aircraft design, and the aircraft ceased production. They had the benefit of being low cost, cheap to operate and a low flying speed (low stall) so they could be used by the Police for management of vehicle traffic on roads.
There mite be other practical reasons why they didn't do that. Such as the complexity of the additional piping. Weight. Cost. Extra piping and bending of the pipe also reduces efficiency due to friction and changing direction of the exhaust gasses. If they could do that it would be quieter instead of having the exhaust going into the fan. But one benifit of having the exhaust going into the fan is u get free deicing without having to have additional systems which add weight and use power. Like on the Avanti.

The myth that surrounding a propeller with a duct somehow improves efficiency, is just that. A myth. Propellers is cruise have very small advance ratios, and the lift coefficient approaching the blade-tips is practically zero. So there is little tip losses. Most fixed pitch propellers made of metal or composites reach 85% efficiency at their design velocity, torque and rpm. The best propellers are around 90%. There are no ducted fans that can do much better than 80% that I am aware of. Even R/C ducted dans are notoriously sluggish and power hungry for their thrust output.

Flew it in TRier (check the acft reg.), Germany, some 30 years ago and its more powerful two sister aircraft. A real pleasure to fly but sadly not being bought by the Luftwaffe. Have fun
A wonderful concept that deserved better success. RFB had been perfecting the idea of the fuselage mounted ducted fan for many years starting with powered sailplanes.
This but with blades in the wings to aid in shorter/more verticals take off and landing, and also can go at slower speeds. Add a few safety features like a soft air padded emergency landing, and you got a personal flying car for everyday average people.
Build in the 80’s by the German company Rhein Flugzeug Bau in Monchengladbach. The Fantrainer, as it was called, was to be a cheaper, jet like, basic trainer for military use. They did a lot of test flights over my home town. Made a horrible whining noise. One aircraft blew up its engine and made an emergency landing at our gliding field. It never was successful.
The speed comes from the extremely high RPM of that cut down fan diameter. Because the blade helix angle times rpm is airflow velocity. They require a lot of power to work. And are sluggish at low speeds compared to props.
Very cool aircraft and concept, shame it didn't the future it deserved. I've heard a new startup company is trying to bring that design back but again trying for military contracts. I think it would make a great G.A. or experimental aircraft if it could be produced affordably.
I think the turbulent air from the forward fuselage and wing roots going into the fan reduces the efficiency a bit. Good visibility up front though. Plus the fan discharge going over the rear fuselage kinda reduces efficiency too I think. Better to stick 2 of them on the wings I think. But smaller turboprop don't do so good in fuel efficiency. So 2 smaller ones not so good either.
The lack of turbulence across the wing surfaces improves control stability and precision like a jet, and I imagine that if the fan and turboprop counterrotate they could torque balance each other. Turbulence could improve rear aleron control response but that would have to be determined by simulator or wind tunnel tests. But I think it's a good trade-off for the simplicity and efficiency of the engine, a fan and a turboprop, no multi-stage compression.
Congratulations 🎉 also congratulations on the 100k subs - well deserved everyone. And right now as I’m finishing this video you’ve added another 63k subs 👏👏👏
Curious to know this propeller efficiency data? What are the advantages over conventional propellers? I know that a good design must exceed the conventional propeller by more than 30%. So why does such a small aircraft need such a large engine power? .
You can get a kit that is fairly close in principal design to this. It looks like an F-22 and is powered by a piston engine. It's actually an excellent layout and makes it perform more jet-like even when very low power is used. COG thing.
Got some stick time on the Opitca Scout (piston though) back in the 80's and it was different and surprised it took so long for someone to do an encore...

Bottom line, the 80s, early 90s was a crazy time as both makers and consumers figured out what they wanted from a computer, with all these weird experiments.
These variations mentioned in the comments are fascinating. Not a variation on the Pusher designs but a novel idea. How could it be made safe and commercially viable?
That’s incredibly cool however it does need a grill in front of that fan because someday it’s gonna suck something right in and that planes going down. It should also have an emergency parachute on the top of it as a secondary line of safety just pointing out something obvious folks.❤DALE.
I alway wondered why I never saw them in production. Turns out it was built to be a military trainer and lost the competition and the company finally failed. There is a video on RUclips someone did about it. It did provide true centerline thrust like a jet, shortening training cycles. I would think a model with a 200hp engine, built with today’s composites and not to military specifications, which would cut a ton of weight and complexity from the design would do well in the experimental space. Especially if 4 seat (2x2) seating was used.
Very good design though. Since the turboprop fans is behind the cockpit, maybe they can improve the plane which can detach the cockpit from the engine parts should there be major malfunction which the cockpit can launch a parachute for both pilot and passenger for safety.
It's design like a fighter so it has a unstable design but no weight is almost in the middle why do you think the wings are there it's best for lift to be by center of mass
So, if I follow correctly, the propeller fan is in front of the turbine, directing air towards it as it spins just as a compressor/fan would in a normal jet... So the ducted propeller reduces turbulent air flow and makes it more directed at the turbo by sitting right in front of the turbine. I wonder how different the mechanism really is for a normal jet engines fan/compressor vs this propeller.
I just checked and it looks a lot like Rick Hunter’s stunt plane from the first episode of Macross. When he first show up at the island. It looked like it had solid rocket assist motors around the edge of the duct.
It predates Macross by 7 or so years. The designers at Studio Nue were very in tune with aviation designs and likely would have known about this plane. On a slightly related note, the VF-1 Valkyrie engine sound is from a J-79 engine, recorded from an F-104 or F-4.

They should exhaust the turbine behind the duct as the expanding hot air would reduce drag. (Meredith effect).
There mite be other practical reasons why they didn't do that. Such as the complexity of the additional piping. Weight. Cost. Extra piping and bending of the pipe also reduces efficiency due to friction and changing direction of the exhaust gasses. If they could do that it would be quieter instead of having the exhaust going into the fan. But one benifit of having the exhaust going into the fan is u get free deicing without having to have additional systems which add weight and use power. Like on the Avanti.
If its a classic turboprop engine, then the exhaust exits up front
Turn prop tips 45 degrees , problem solved ,😊
It's not a turbo prop... it's a piston engine turning a ducted fan

It increases the efficiency of the propeller/fan as there are less losses at the blade tips.
And it dumps all the weight behind the center of it's length! It's niche and unused for good reason

Truly beautifull

So, if I follow correctly, the propeller fan is in front of the turbine, directing air towards it as it spins just as a compressor/fan would in a normal jet... So the ducted propeller reduces turbulent air flow and makes it more directed at the turbo by sitting right in front of the turbine.
I wonder how different the mechanism really is for a normal jet engines fan/compressor vs this propeller.
That's basically the same as a high bypass turbofan, only slightly lower thrust (and a bit quieter)
