Any landing you walk away from is a good one...

Unfortunately, you left out the most important factor along with its laminar flow fuselage: It has a high-aspect ratio wing. This means it has a long wingspan with a short chord line (it’s long and skinny). This type of wing provides maximum lift and minimum drag, which is why you see it on gliders. Except, the trick here is making it strong enough for what appears to be a >10,000lb, 400kt aircraft. That’s where the use of advanced composites that were not formerly available comes in. Cheers!

thanks for this video! this plane recently came across my radar and to see someone put so much effort into a video showing it off has been great.

Well done again, SE!! Excellent narration delivery and copy - with lots of info and insight on an aircraft I didn't know about! Thank you.

This is really cool, a few challenges I see are: 1. Pressurization - Piston aircraft often have issues with pressurization. A good comparison is the Cessna P210 where the weight of the pressure hull and low engine air output limits maximum flight altitude. I wonder how much the figures they give assume high altitude operations. While the wing design is good, the engine can only put out so much power to get it to the needed altitude while maintaining pressurization, anti-icing (in poor weather), electrical, hydraulic, and air conditioning systems. 2. Single engine - This will find a market but for commercial service the aircraft will not be permitted over water and will have a limited scope of operation due to that one engine. A number of executive jet customers are not permitted to even fly on single engine aircraft due to their life insurance policies. Additionally overwater and remote operations will be heavily restricted due to regulatory requirements of a single engine aircraft. 3. Payload - Again, with one engine the aircraft will be limited on its payload with one piston engine, no matter how good that engine is. The An-2 is the largest single engine piston in the world, it needs a 1010 HP engine to move a 3000 lb payload at sluggish speeds and low altitudes. Will the 500 HP engine be enough for this aircraft to be able to move a payload of 2000 lbs with the 200+ gallons of Jet-A weighing about 1350 lbs while cruising in the flight levels? There is more to flying than cruise performance, the aircraft will need to meet minimum climb gradients for various IFR approaches and departure procedures in order to be considered practical for commercial use. 4. Known icing - Again we look at anti-icing and de-icing solutions, both of which will take air from the engine and hinder power output. The main issue is how the wings, control surfaces, and engine inlets will be protected from ice accumulation in flight. The propeller is in an advantageous position for this, as pusher engines are their own prop anti-ice. However for the aircraft to be commercially viable it will need all weather capabilities. Super-critical wings such as the one this aircraft sports are extremely susceptible to negative effects of airframe ice accumulation. There are a lot of regulatory hurdles a new concept aircraft has to overcome, I wish Otto the best in navigating that bureaucratic nightmare and I hope to see their plane in production in the future. The items I listed here are the first thoughts that came to mind as hurdles an aircraft design such as theirs will have to address during its development phase. While many people say "develop and improve" in aviation this is not an option, the aircraft must meet their commercial quotas in order for further development and each of the items listed here will be things serious aviation businesses (anything beyond personal transportation aircraft for a wealthy individual) will be looking at. Cost of acquisition and maintenance will also be a factor, of course - but that number will generate itself as development comes to an end. I would like ideas like this to flourish and seeing another revolutionary concept flounder into obscurity only hampers future innovation. That said, it's awesome they've already got a prototype and pulls them firmly out of the realm of "investment scam" or "pipe dream" that so many concept aircraft die in.

Although technically a piston single, this is an animal entirely different from a Malibu, more comparable to a TBM750. I don't see it going toe to toe with twin jets. Otto's Celera is poised to take the turboprops' lunch. Also not an easy task, as the challenges you mentioned equally apply to that segment. The diesel is turbocharged and the fuselage designed for pressurisation from the start, the P210 thus not a good comparison. Although it has its following. Speaking of which, I'd like to see a smaller sibling with 4 to 6 seats in total.

Crosswind landings will be a nightmare due to the awkward and relatively large cross section of the fuselage. Also, high density altitude performance will be pretty terrible with that tiny propeller and small wing.

aviation has a large carbon footprint, so we'll tax it (hopefully) to force change.. Smaller planes (propeller) can be made electric, so yes jet fuel will get much more expensive.

Putting the prop at the back of the plane is a big part of why they are able to achieve such smooth laminar flow. The wake, or prop wash, from having it up front completely screws up the airflow over the body of the plane, but it's the way we've done it for so long that's the standard. The center of gravity moves to the rear of the plane when you put the engine in that back, hence the unusual wing placement.

Assuming those capabilities are real (which I read is a big assumption), it could be used to take families on holidays over medium distances pretty cheaply, and in comfort. Replacing the "air bus" with the "air taxi"!

This feels like a more radical version of the Piaggio Avanti, which also put focus on maximizing laminar flow over fuselage and wing, and was designed to have performance comparable to jets. But I gotta say the Avanti seems like a better compromise (better field performance, better cockpit visibility, uses a widely available engine, etc) and it looks much better (important).

To quote a Smithsonian webpage: at extremely high altitudes, the difference between stall speed and never-exceed speed narrows into what pilots call the “coffin corner.” Perlan 2’s wing design allows a luxurious 17-knot (20-mph) difference (The U-2, routinely flying over 70,000 feet, has only a five-knot difference). And though computer simulations show a tendency to enter a tail-wagging oscillation known as Dutch Roll, a yaw damper on the tail should counteract the phenomenon. There are always compromises. The important ones are to ensure control is as easy as possible. I remember watching a video here on KZread where some off schedule pilots decided to try to see how high and fast they could get their aircraft to go, and ultimately damaged the aircraft. I can't remember if it was total engine failure with an emergency landing or they actually crashed... I vaugely think I've seen one of each.

Something that I thought: it can travel thousands of miles on a single trip, but it doesn't have to. What benefits are there to being able to make 10x 400mi trips off of one tank? 20x 200mi? Decreased times due to fueling. Or, reduced fuel load per trip (assuming you're gassed up to the minimum needed to get to the next destination). Fascinating machine.

Sky! Glad to be back! Playing catch-up!!

this new aircraft fits into a unique place, as explained by the narrator, and the selling points and benefits are very attractive. Flying from a smaller regional airport is way more convenient, and it will put the "fun" back into flying instead of a dreadful experience as it is now.

current pandemic + low operating costs = more incentive for people to trade air carriers for charters

But my own R/C rear-mounted props are always louder than my front-mounted prop R/C models. Here's an example: kzread.info/dash/bejne/aKOitLpwpMu0YLg.html

This plane has me very excited.

What a f*** fabulous idea. Laminar flow with an internal combustion engine . This is a winner . The narrator is great as he to is so amazed at the metrics he wonders if its true . Great video. Australia should order dozens of these things to service our remote towns.

I have had the Celera 500L on my "'sites" (misspelled "sights") for about 3 years now. Thanks for the excellent video.

@@christophertstone Wow! Thanks for the correction. I misspeled like a 7-year old.

Looks like it would be wonderfully efficient at lower speeds, like 400 km/h cruise. The design also looks promising for large volume/weight freight.

Your narrative writing is better than the video! This is one of the best video sites on KZread for both content and video style values. Totally surprised, we find even your delivery is much clearer and easily understood You appear to come from a professional writing background related to aviation. Where can we learn more about your amazing achievement with Skyships Eng?

Perfection in practice. Go get them!

It would be interesting to see what that amazing airframe efficiency combined with an electric powertrain could do. Even if it only had 1/10 the range, the economics of electrics and the need for short range air travel is compelling.

I was just about to comment the same thing. With a pure ev power train the engine cooling ducts could be removed and the thing could fly at a much higher altitude. Stronger landing gear and longer wings should give it very usable range.

No such thing as a viable electric airplane. First, weight is important. Unlike a car. A plane becomes more efficient, the longer it travels. A battery weighs a lb at the start and at the end of its journey. The only way an electric plane will ever happen, is a completely revolutionary development in battery power. A development in planes, is maybe a 10% increase in the viability of electric, while the equivalent in battery development, would double or triple the viability in electric. You’re looking at the wrong end of this horse.

@@kentonian and it would still here heads and tails less viable than liquid fuel power trains. You people really don’t get how far away we are from such things do you? Some improvements in airplanes aren’t going to make electric planes magically viable. A battery still weights a shit ton, and that is the MAIN problem with airplanes. Weight. There is a reason you pay extra for luggage, and we’d pay extra for the tire around your gut, if we weren’t so scared. A plane gets lighter as it travels. It’s literally cheaper to fly a plane, the longer the plane is in the air. You can NEVER say such a thing for electric, which is why it’s only viable on the ground, where distance isn’t a concern, and you can have smaller batteries and dumping 50-100lbs of weight will not effect things much. And even then, it pales in comparison to the bang for your buck from liquid fuels.

I’d be interested in a hybrid power plant not quite Formula one but capable of lifting the Aircraft with the Fuel engine then cruise on the electric drive when needed or glide to save both forms of energy. I think that the aircraft could also charge in flight and and if the upper surfaces used solar technologies now in development to top up and extend the possible range of electric driven flight.

@@jamesbizs solar panelled aircraft could have extended flight especially since they could fly above the clouds . We are currently developing many flexible and more efficient cells to fit to odd surfaces like cars and houses and lightweight cells on an electric or hybrid Aircraft makes a lot of sense to me … daytime flights would be Most advantaged of course …

Until you pointed it out, I didn’t appreciate how really thin and minimal those wings are

Because they aren’t used as tanks. High aspect ratio wings have other beneficial aspects. Apparently they aid in the laminar flow.

Brings the P-51 Mustang of yore to mind. I think it had the original laminar flow wings.

Sounds great and it will be successful!!!

Humpty Dumpty in trhe air! Fascinating!

If they can scale this up to 12 to 18 passengers, then it gets interesting. I have flown on a 25 passenger turboprop from Pittsburg, PA to St. Louis, MO. There were only about 18 passengers on board. It flew low and fairly slow. Engine noise and turbulence made the flight less than enjoyable. A plane like this could fly higher, faster and make the flight more enjoyable.

Piaggio Aviation had a great quote about their Avanti plane, which has a pusher propellor design: "When was the last time you saw a ship with its propellors at the front?"

This is essentially a disruptor product, and I'm excited about the prospect!

This will work. Incredible engineering behind this aircraft

Immediately put me in mind of the lifting-body experimental craft that NASA used to mess about with - like the HL-10. Either way, does look like a definite advance in aero design. Really hope they get it certified and into production.

What a great egg!

Very good presentation; amazing posibilities;

Fantastic video!
