	Flying Wing
		The shape of the Flying Wing is adapted from the zanonia seed which is found in southeast Asia.
		The dime is taped to the underside of the leading edge of the Flying Wing to increase its weight there and balance the pitching tendency during gentle, gliding flight.
		The Flying Wing begins looping maneuvers and continues until drag slows it and the Flying Wing gently glides to the ground.

	Flying wing - The Black Vault Encyclopedia Project (Site not responding. Last check: )
		Flying wing is the generic designation given for a fixed-wing aircraft configuration which is capable of stable, controllable flight without the aid of lifting surfaces other than the main wing itself, that is, without auxiliary surfaces such as "tails" and "canards".
		The flying wing's potentially large internal volume and low drag made it "a natural" for this role, and was studied in depth by Jack Northrop in the United States, and Alexander Lippisch and the Horten brothers in Germany, where Hugo Junkers had in 1910 patented a wing-only glider concept.
		Junkers conceived futuristic flying wings for up to 1,000 passengers; the nearest this came to realisation was in the 1931 Junkers G-38 34-seater Grossflugzeug airliner, which seated passengers in cabins inside the leading edge of the inboard wing panels.

	The Oblique Flying Wing Page
		An OFW is an aircraft without a fuselage that can vary the angle of its wing with speed: as the aircraft accelerates to supersonic, one side of the wing sweeps forward and the other side sweeps back.
		Maneuvers were performed at wing angles of 0 to 45 degrees.
		In addition, supersonic wind tunnel tests were conducted at NASA Ames of an oblique flying wing.

	Crash of the YB-49 - Flying Wing
		What caused the crash is not known, but it was suspected that the flight crew managed to surpass the "red line" speed of the aircraft while descending from 40,000 feet, causing the outer wing panels to be shed and the aircraft to disintegrate in midair.
		Various pieces of the aircraft including both wing tips were scattered from the main wreckage on a heading of 50 degrees.
		A wing tip came down a few miles from the main crash site and led to the belief that the crash was cause by a structural failure.

	Dictionary : Wing_types
		A small wing called a canard is often attached to the fuselage near the front on this type of aircraft.
		The flying wing is an aircraft design where the wing forms virtually the entire airplane and it sweeps back from the center of the aircraft.
		Dihedral is the angle at which the wings are slanted upward from the root of the wing (where it is attached to the fuselage) to the wing tip.

	The Wing Suit (Site not responding. Last check: )
		Patrick brought the wing suit to where it is today - an efficient flying wing with an airfoil that can be customized in flight by the human body.
		Two of these wings stretch from the wrists to the hips to the armpits on each side of the body, while the third wing is stretched between the legs from the knees up.
		The awesome thing about the wing suit that is different from any other flying wing in the world is the ability to change its shape while flying it.

	Basic Design of Flying Wing Models
		A survey of the available literature on the topic of flying wing and tailless model airplanes shows, that in most cases, the airfoil selection is mentioned, but no reliable data for the selection are available.
		In the case of an unswept wing ("plank"), even an airfoil with a positive moment coefficient is necessary, to avoid upward deflected flaps under trimmed flight conditions.
		Typical values for this number for a flying wing are between 0.02 and 0.05, which means a stability coefficient sigma of 2 to 5 percent.

	Tweety Bird - Flying Wing (Site not responding. Last check: )
		He lowered the elevon on the inside panel of the outside wing a bit, suddenly the plane was actually flying.
		Flying wings are more of a challenge to trim, CG placement appears very critical.
		The elevons are attached to the rear of the wing with copper wire and adjusted with from 3/32" to 1/8" up at the trailing edge of the elevon.

	NASA - Wing Design Would Be More Fuel Efficient and Environmentally Friendly
		The blended wing body model has a whole series of control surfaces along the trailing edges of the wing, 18 in all.
		One of the challenges to controlling a flying wing, according to engineers, is determining how to blend the control surfaces to make the vehicle turn correctly or to pitch up and climb.
		Researchers say a blended wing body could be useful as a multi-role aircraft for the military, including functioning as a tanker, cargo or transport plane.

	Flying wings
		The twist-angle is the angle between the airfoil at the root of the wing (nearest to the fuselage) and the airfoil at the tip of the wing.
		This way you have the necessary down force to compensate the turning moment of the wing (the force-arm (distance between center of gravity and elevators) is long enough) and you don't need to have a long fuselage to hold the tail.
		"Mitchell used this technique for his B-10 flying wing ultra light." This quote from an Air Enthusiast edition probably mentioned that if the cockpit would be higher placed, that the control surfaces needed to be larger to control the airplane.

	Howstuffworks "How Flying Wings Will Work"
		More people are flying than ever before, and the increase in air traffic has created a bottleneck at airports around the world.
		Responding to the sharp increase in travellers, Boeing and NASA are developing a new kind of passenger airplane that will be able to carry 800 passengers per flight, which is about 160 more than a 747.
		The new blended-wing body, or "flying wing," design does away with the cigar-shaped fuselage and tail section that have been mainstays of modern passenger planes since they took off in the 1930s.

	Flying Wing construction (Site not responding. Last check: )
		Even though you throw an induced drag burden on this type of flying wing you gain benefits by losing the Fuselage and all the tail assemblies.
		First reinforcement tape is used on the trailing edge of the wing on both the top and bottom surfaces these are run as half panels from the center with a little extra so it overlaps at the wing tips and helps tie in the structure.
		The rudders are placed ~1” in parallel to the tip of each wing (draw a line with a ruler), cut a vertical slot starting just behind the spar the length of the base of the rudder and widen it to snugly hold the rudder.

	Horten: two brothers, one wing.
		The benefits of a flying wing become easy to understand when we consider that the fuselage and the tail section produce 30% to 50% of an airplane's drag, thus the reason that purists such as Lippisch or Northrop pursued this concept.
		The idea of a flying wing is far from being a novelty; it made its appearance at the birth of aviation, and it was a concept adopted by many precursors.
		Their stubbornness in their researches resulted in the production of a flying wing possessing great flying qualities, beginning with the first one produced to the last one, even introducing the piloting of the machine in a laying down position to reduce the extra drag produced with a normal canopy configuration.

	Northrop N-1
		Although the 1929 flying wing was not a true all-wing design because it made use of external control surfaces and outrigger tail booms, it paved the way for the later N-1 M, which proved the basic soundness of Northrop’s idea for an all-wing aircraft.
		The center of gravity, wing sweep, arrangement of control surfaces, and dihedral were adjustable on the ground.
		That is, the aircraft’s wings alternately rose and fell tracing a circular path in a plane that lies between the horizontal and the vertical.

	Your Zagi Flying Wing History
		Even though flying wings do not have a long history, quite a bit has been developed to get us where we are today with our tiny foam copies of the N-1M.
		They added vertical winglets and wing fences to help stability problems and two of the bomb bays were turned into fuel tanks for the engines.
		Subsequent tests to document the radar profile were completed to demonstrate the radar deflecting shape of the flying wings, then promptly filed away and perhaps forgotten.

	SPACE.com -- On Bended Wing: Flexible Flying Machines
		Since the active aeroelastic wings in the Dryden project are lighter than non-modified versions, they could boost the range or payload capacities of future aircraft, Myers said, adding that a second phase of test flights should begin in August.
		To fly fast, the truss could fold into a small wing shape, then expand both wing cross-section and area to accommodate slower flight.
		Lesieutre's truss system is still in the modeling stage, and he envisions it could be placed inside a wing with a segmented, overlapping skin akin to a fish, and push and pull on the surface as needed.

	Oblique Flying Wing
		An Oblique Flying Wing (OFW) aircraft is an asymmetric flying wing that varies sweep in flight to improve high speed performance.
		The variable sweep is achieved asymmetrically on the oblique wing, with one wing swept forward and the other swept aft.
		The OFW program will integrate technologies such as advanced controls to develop and fly a supersonic X-Plane to demonstrate the feasibility of the concept.

	Oblique Flying Wing, Supersonic Aerodynamics
		The oblique flying wing (OFW) is a wing of elliptic planform having mininum wave drag at transonic and supersonic speeds up to M=1.4.
		For minimum wave drag due to lift the equivalent body of revolution must be a Karman Ogive; whereas for minimum wave drag due to volume of the equivalent body of revolution must be a Sears-Haack body.
		The use of the OFW would be limited to transonic and low supersonic speeds, since the increasing sweep reduces the effective wing span, which on turns increases the induced drag.

	Gryphon Single-Man Flying Wing - Gizmodo
		But no, this Gryphon Single-Man Flying Wing is a parachute system whose 4.9-foot Delta wing has two jet engines on board that can carry a paratrooper 110 miles on a half gallon of jet fuel.
		The mission starts when the brave soul wearing this birdman outfit takes a flying leap out of an airplane at 33,000 feet—hopefully equipped with warm clothes and oxygen—and flies the jet wing wherever he's going until he gets to an altitude of about a mile.
		It would be cooler to fly from the ground to 10k feet on a rocket then parachute down.

	Blended Wing Body - New Concept in Passenger Aircraft
		The low effective wing loading of the BWB and its beneficial trim effect means that no exotic high lift system is necessary; only leading edge slats are necessary on the outboard wing, with all trailing edge devices made up of simple hinged flaps which double as elevons.
		The ideal cruising aircraft is a simple, elegant flying wing, and everything that does not contribute directly to generating lift should be integrated in or on that wing, if it is to retain an aerodynamic purity.
		A more promising alternative would be to take the basic wing structure, as described, graft a central tubular fuselage extending ahead and behind its center section on it, remove the hybrid laminar flow control outer wing panels and replace them with inward and rear-facing smaller horizontal winglets located at the tips of standard vertical winglets.

	Muche's Warbirds: N9MB Restoration
		The N9MB, and all of the Northrop flying wing designs, came about because Jack Northrop became convinced as early as 1923 that the limit had been reached in conventional airplane design development.
		This aircraft, a true flying wing design, was to have a wingspan of 172 ft and be capable of carrying a bomb-load of over 52,000 lbs with a range of 7500 miles.
		Lack of documentation complicated the project (Northrop had been approached early on but had declined to assist because of the liability involved in a flying restoration) and each part or section had to be disassembled, identified as to construction, material and function, and then either refurbished or remanufactured.

	DavisWing
		The Davis Wing uses the combined effects of wing sweepback, small vertical fins and flow fences, cowling side loads to produce the needed yaw stability.
		The Davis Wing had enough internal volume to allow for the Cold Jets and all of the necessary systems, with room to spare.

	The German Flying Wing
		He is the one who developed the theory of the flying wing and subsequently of all the models and aircrafts built by the brothers.
		As far as the "flying saucer" is concerned, a number of people were contacted in order to verify whether or not any such design at any time was contemplated or existed in the files of any German air research institute.
		Twining's Letter, Lt Col Walker, at the Air Material Command, asked his operatives in the field to discretely track down the Horton brothers and ascertain whether their radical "Flying Wing" designs- developed during WWII- might be responsible for the rash of Flying Saucer sightings in 1947.
