    9:45 Fun fact: The Wright Flier, the worlds very first airplane was designed to be unstable. Both the wing and the canard provided lift, meaning if the plane left level flight it would be pushed father out of level flight by the passive forces. This was a deliberate design choice by the Wright Brothers, but subsequent airplane designers disagreed with this design philosophy and future aircraft designs were made to be stable, as you described. For the Centennial celibration of the Wright Brothers first flight a replica Wright Flier was built. Several highly trained and experienced test pilots tried to fly it, landed and refused to try again because the plane was so difficult to control. I'm not sure if the first flight was actually reenacted, but it makes that first flight even more impressive when you think about the fact that test pilots with thousands of hours of flight time were afraid to fly this plane, and the Wright Brothers did it with no flight experience at all. Can you imagine walking out to an airport, renting a Cessna 172 (one of the easiest planes in the world to fly) and teaching yourself to fly it by climbing in and taking off? You could, in theory do this. Flying an airplane isn't much harder than driving a car. But it would be highly illegal. But this was how the first generation of pilots learned to fly. Except they were not renting airplanes carefully designed by aeronautical engineers to be easy to fly. They were flying planes they built themselves with no understanding of aeronautical engineering whatsoever. Or at best very little knowledge. Early aviation is a wild and crazy story with plenty of death.

    The very first airplane are you sure? Ader's Eole wasn't a plane because it only flew 50m in 1890 but the Wright's flyer was because it flew 255m after having been catapulted? In the end of the day, Santos Dumont's 14bis remained the first to take off by itself (which is what self-propelled means) and Blériot XI crossing the English Channel was the really first truely operational airplane.

    Having a canard does not necessarily make the craft not stabile in pitch. if the Lift curve of the stabilizer is less steep than the wing, a pitch up will self-correct. By the same token, you can have a stabile design with a lifting tail. To be stabile, the combined Aerodynamic Center needs to be behind the CG.

The entire flying wing would have been the passenger compartment and it promissed business class style seats for coach prices. It seems like 25 years would have been long enough to get at least a prototype off the ground (pardon the pun). Yet air travel remains stubornly miserable.

    This was a very well-researched piece, because you caught a lot of the "why we haven't done this yet" problems, which I suspect was your goal. If I may offer a few criticisms... --"Tube and Wing" was in play from the late 1910's or earlier, and the fact you were specifically talking about jets isn't really relevant for the class of plane being discussed? The reference to fixed diameter tubes later helped specify what you were referring to, but it's still going to be confusing. --You've conflated 'horizontal stabilizer', 'tail', and 'vertical stabilizer' a lot here. The reason the flying wing design without a vertical stabilizer (and instead relying on fly-by-wire) was chosen for the B-2 was always because RCS (Radar Cross Section) was the selected trait to minimize by engineering. You can have vertical stabilization _and_ be a flying wing. Even the original Horton prototypes and some later intermediate prototypes still had passive vertical stabilization, as did the more recent civilian prototypes you've discussed. --The chart with "fuel consumption per passenger over time" I think is labelled as "per decade" when you meant "per year", given that it went from 100 to 50, in 50 years, and the numbers cited were between 1-5%. --Flying wings are weird, but you made no mention of the stability gained by allowing for dihedral wings (as observed in literally every civilian and non-military or fly-by-wire prototype shown), as opposed to the semi-anhedral (because the B-2 is both weird and classified) of the B-2 (which, as it's the only full-scale production flying wing is really the only production reference). No mention either while talking drag of the unusual trans-sonic effects in addition to lifting stress of tube and wing designs fighting the Sears-Haack or Whitcomb-area. Of especial note is how the flying wing/lifting wing must not have a tail to follow these, but can still have vertical stabilizers. --I'm not sure how much research has gone into this(cargo), but a lot of the 'pressure hull' problems actually disappear for cargo applications as they don't require life support, and given the lifting body characteristics I think it would be worth mentioning that designing a flying wing that could contain 2-3 shipping containers that, while remaining sealed or venting the container without surface breach could carry those containers (potentially full of vaccine or medical supplies) halfway around the world, given the known characteristics of the B-2 alone? --Mention the engine mounting problems of a flying wing vs. the weight distribution? Thrust alignment on these things is hard (Read: takeoff vs. cruise problem), and needs to be strongly considered as the 3rd element to center of mass/center of lift, but you only passingly touched on it in wing+tube alone? Just some thoughts based on aviation engineering subtleties I've run into, trying to align this more with some of your previous videos (since I know you've discussed anhedral/dihedral before), and reference for some deeper insights for others to discover. I love that you're taking a serious look at the topic, and bringing what was once a fringe aviation thing out into the limelight for other engineering enthusiasts to feast on!

    yeah, can't flying wings simply be passively stabilized by having the center of gravity in front of the center of lift? that doesn't actually require a separate tail, does it? maybe a design could be made that shifts either the center of gravity forward or the center of lift backward in low level flight to increase stability close to the ground, and shifts them closer together for cruising to save fuel, when there is less risk associated with a stall because the plane could easily regain control before hitting the ground?

    @@Ass_of_Amalek Sadly, not really. CoG (which is also the Center of Mass) in front of the CoL means that the pull of gravity will create torque against the push up from the center of lift, making the entire thing want to take a nose dive _right_ into the ground without a lot of fighting control surfaces counteracting this. Regarding moving CoM/CoG, that means that you have to move mass which costs fuel to do the moving, and requires adding mass (which is the thing you want less of to be able fly in the first place) that you aren't using for anything else. And also keep in mind that when you exert 'control' of any kind on anything, you're requiring energy expenditure of some kind (fuel, momentum, altitude, and the like if you're talking aviation or rocketry), so that's also something you want less of.

I've been intrigued by blended wing body aircraft ever since reading in the 1970's about the Horton brother's design work of the 1930's, but had never been able to fully understand the complexities of controlling this type of aircraft compared to the tube and wing design. Your programme illustrated this very well. Thanks. I am disappointed that you didn't give at least a 'heads+up' to the Horton's work in this field. They were the forefathers of everything that you discussed re the B2 and, I suspect, the McDonell design too. I understand that Boeing engineers visited the Smithsonian to inspect the Ho229 prototype as a result of their studies into BWB designs. I could get worked up and rant about the shameful neglect of the Ho229 by the Smithsonian, but I'll control my emotions! Thanks once again for a really enjoyable programme. Have subscribed following this discovery.

    And BS at the same time as the entire reason flying wings are not used in commercial airlines has nothing to do with the design for normal operation. It has everything to do with failure modes and the exiting of passengers from the aircraft during said failure modes. It is a logistics problem, not a technical problem. Solve the Logistics problem, get it passed by the FAA/EASA and then every single commercial aircraft will switch to flying wings overnight. Until then... this is baloney.

He talked about the tubular design is great for pressure vessels, and the flying wing not so. I fail to see the weight reduction in a non tubular design of a pressure vessel over the current designs. If carbon fiber is already implemented in tubular aircraft making great weight savings, the race is lost as it will take substantially more composites to pressurize a non tubular flying wing. I have misgivings about doors in the leading edge of a wing, whether for deplaning, or emergency exits. The leading edge is one of the most critical for airflow and to make it all bumpy by adding doors seems to be a bit sketchy. The inefficiency of the horizontal tail downward force can easily be changed by going to a canard style aircraft which removes this issue and adds the safety of a stall resistant aircraft.

Problem was that the elevators were under so much stress that the jack screw was essentially jammed and human power could not be used to trim into reasonable position using the trim wheels. They flipped STAB TRIM CUTOUT back on to use electic trim, which helped at first but later MCAS made the pitch down correction several times in short period, leading to fatal nose dive

    A lot of my old designs for aircraft in KSP had no angle of attack on the wings or tail, with the center of lift placed in the exact spot of the center of mass. It’s not exactly a bad design, it’s basically what they did with the F-16 IRL. It’s just not amazingly stable. But putting the center of lift further back causes the nose to have a pitch down tendency, which is not convenient if you want to cruise, and it also makes it hard to pitch up effectively. So nowadays I put the center of lift of the wings alone at or just behind the center of mass with a positive AoA tilt, _then_ put the tail on with a negative AoA to avoid the pitch down tendency. It often takes a lot of tweaking to achieve a stable level flight at the preferred cruise speed and to have the fuselage to simultaneously be traveling straight forwards (setting the wing/tail angle wrong can put the fuselage at an angle of attack in level flight, increasing drag and reducing fuel efficiency). Angling lift surfaces in the editor can confuse the position of the center of lift. That’s because for achieving level flight at a certain speed and AoA requires information that the editor doesn’t give you. To get level flight at a target speed with an angle of attack of 0 degrees, you need to know that, at the target speed, the design will generate exactly 1 g of lift, and zero torque. But the editor doesn’t tell you the amount of lift or torque at different speeds, just the average lift vector. Also, lift is supposed to be a vector perpendicular to direction of travel, as any aerodynamic force in the backwards direction is really drag, not lift. And yet the dumb editor in KSP will often show you a lift vector pointing backwards to some degree. Completely not useful.

It will probably be a final issue that will need to be addressed before there is wide scale customer acceptance of the new airplane design. I think a lot more people than they think are concerned about having windows. More people want to look out of an airplane window than don't. I'm amazed at how few comments there are about this facet of the design. That's a problem with engineering, engineers frequently forget the human aspect and just go by the numbers. These are not "people movers", they are vehicles that transport human beings, human beings who will not ride in something that they are uncomfortable riding in. A major failure of the airline industry is the "cattleing" of their customers. This needs to STOP!

    I'm glad you covered the cabin pressure factor. This was a concern of mine when we were working on our supersonic commercial flight capstone project as we started deviating from the cylindrical fuselage configuration. One important limitation not covered here is the height vs width of the airframe. If the internal cabin is to be high enough for passengers to walk around, the wingspan must be much larger than that of conventional regional airliners that carry 100 or so passengers. At that point, you might as well add more rows of seats. Its likely we will never see a regional airliner or charter plane of this design for this reason, mainly just international flights where you can sell the extra several hundred seats. If the industry is forced in that direction, they will have to compensate by scheduling less frequent flights to fill the seats.

    The flying wing design has a problem with YAW. This originally caused the Northrop XB-49 to crash, reaction time is S-L-O-W. The B2 Spirit gets around this by fly by wire design by not getting itself into an uncontrolled yaw condition. Also the control surfaces are quite different notably the split flaps. These problems will be rectified because a flying wing and lifting body is a heck of alot more efficient in fuel and in passenger space too! I see the clean airliner running on hydrogen which has the highest specific impulse, not battery electric, it's just to damn heavy! So the lifting body design has a lot of advantages in this area with the only design problem be in controlling the aircraft. I know they will solve this however.

    I am retired mechanical engineer and I just wanted to say I loved your description of how you study at the end of the video. Some how I picked this up at university when some courses allowed us to bring one or two pages of notes into an exam. I soon realized that the act of generating the condensed notes meant that during the exam I had such grasp that I did not really need the notes anymore. I started to create these "cheat" notes for every course and whether or not they were allowed into the exams became irrelevant. Eventually I had a binder of these notes that I still have to this day. I could have used your notebook then!!
