However, any single inventive feature may not address any of the problems discussed above or only address one of the problems discussed above. Further, one or more of the problems discussed above may not be fully addressed by any of the features described below. Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings. While particular embodiments have been described, it will be understood that various modifications may be made without departing from the scope of the invention.

[0037] The Flying Machine with Disc Shape Structure (Flying SaucerCoincidental Resemblance);

[0038] The patent idea and principal is based on the use of all the airfoil wing principals of aerodynamics on normal segment with wider rear edge than the front edge of Delta airplane wing foil with long root chord and finite short span with wider rear edge of the delta wing foil, with good lift NACA characteristics by Adding (integrating) the equal surfaces together to form complete circular disc (flying Saucer) and make it structurally stronger built, stiffer and at the same time lighter, its long root chord also allows a deeper structure for a given delta aerofoil section, providing more internal volume for fuel and other storage and Because of its light, robust structure with miniature span at an elevated angle from the ground level at the leading edge and on the ground level at the trailing edge end at an angle range between (0-45) degree and then join these equal segments next to each other to form complete disc FIG. 2, FIG. 3 but with hole in the middle where the cockpit, (the pilot cockpit can be placed at the top or at the lower part or the bottom of the flying disc to have better view on landing with the fuel tanks, luggage, equipment, and all heavy equipments, to lower the center of gravity of the flying disc for better flying disc stability in flight) and where the start of airflow entrance into the airfoil leading edge and at the tail of this disc where the airflow will exit the circular disc airfoil (Flying Saucercoincidental resemblance) FIG. 3, and using the fact that airflow tends to stick to gently curved surfaces, a phenomenon called the Coand effect and it is totally symmetrical, so in theory it should be unidirectional as directed by the thrust direction, (or duct fans with swivel gears) specially if several vectoring thrust engine are used in sufficient numbers (minimum of 3-4) engine fitted on the disc perimeters to be able to direct the disc360 degree in any direction, and Vector up and down and these vectoring engine can be directed to lift and fly the disc and using all ring thrust to push the disc in any direction or in one direction

[0039] It should be noted that the overall flying disc shape saucer will have the shape of thick or thin aerodynamic foil depending on the use of the disc mission (subsonic or supersonic) and in all cases the disc will have lifting aerodynamic foil similar to NACA thick or thin foil characteristics and the transmission, of mechanical forces between a solid body and a fluid occurs at every point on the surface of the body

[0040] The wing surface of the disc shape will have thick airfoil wing like NACA 4412 (as an example) with good properties Or any good airfoil wings lifting abilities to give maximum lift, It is well known that the more curvature of the foil the more lift the wing will carry, also the greater the wing area the more the wing will lift and if the area of the wing is doubled the lift will also double, Which make the flying disc have an advantage over the usual airplanes All the outside surfaces can be covered with solar panels to help in supplying the Electricity and power needed to the flying Machine

[0041] All flying airplanes and helicopters depend on one theory (aerodynamic forces) which explain how wings airfoil use the incoming air to produce lift and drag on the body of flying object FIG. 10

[0042] The theory use Bernoulli principle FIG. 7 which use the fact that when air passes awing (curved shape at the top surface upwardthe more the better lift) the faster the air on say the upper part of the wing the less the pressure on the upper part of the wing which means an up lift produced on the wing, on the other hand if the lower part of this wing has curved also upward or straight with no curve then the air speed on the lower part of the wing will be slower than the upper part of the wing this can be explained with the logic that at the edge start of the wing air passing the start of the wing edge will split in two directions upper part and lower part the upper will have to travel longer distant than the lower part of the wing which can only happens if the air at the upper part of the wing will travel at much faster speed than the lower part of the wing to meet together at the same time at the end of the wing which what must happen in real wing air connection and this apply to the patent principals with the disc shape flying machine with middle central air inlet hole FIG. 3 where the cockpit also is placed and the curved upward disc delta shaped equal segments joint together and if these segments are finite then near smooth surfaces can be obtained on both upper and lower surfaces of the discs with all the aerodynamic forces apply in flying the disc shape flying machine, which can be confirmed by using Bernoulli formulas. All heavier than air flying machines must use the above theory to fly or use direct jet propulsions to push rockets against gravity or helicopter using rotating wings (propellers)

[0043] All flying machines use wings which can have thick shape curvature for slower heavy loads carrying flying machines (transport aircraft) but has high drag on the body of the flying machines, on the other side fast flying machines (fighter aircraft) use thin slender wings with much faster speed and less drag but carry less weight

[0044] The design of wings (airfoil) starts with the required characteristics for the lift coefficients, Reynolds or Mach numbers, stall characteristics, moments, thickness, drag, lift etc. The design can be done using numerical methods (using computers) or using design codes and improve on the design using wind tunnel in trial and error to fund best airfoil shape and all of the above designs points will apply and used in designing the new patent flying discs once the parameters are known to the designers with loads and speeds and takeoff distances and all other parameters and all the geometry and the shape of the body can be made using the patent geometry parameters from any suitable materials like fiberglass, polystyrene covered with aluminum foils or aluminum or very thin titanium or carbon fiber or any other suitable materials, using molds and jigs for the molds manufacture and jigs for assembly of the body of the flying discs using the above methods and apparatuses and in the designs will have several designs aids to increase lift

[0045] Engines and Thrust:

[0046] When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system. The force applied on a surface in a direction perpendicular or normal to the surface is called thrust FIG. 12, a fixed-wing aircraft generates forward thrust when air is pushed in the direction opposite to flight. Propeller, or a rotating fan pushing air out from the back of a jet engine, or by ejecting hot gases from a rocket engine The forward thrust is proportional to the mass of the airstream multiplied by the difference in velocity of the airstream

[0047] Reverse thrust can be generated to aid braking after landing by reversing the pitch of variable-pitch propeller blades, or using a thrust reverser on a jet engine. Rotary wing aircraft and thrust vectoring aircraft use engine thrust to support the weight of the aircraft, and vector sum of this thrust fore and aft to control forward speed

[0048] Rotating Duct Fans which can be fixed to the flying disc rear edges at the perimeter similar to jet engines and can be directed downward to the ground (minimum of 3 or 4 engines) at equal distance at the flying disc perimeter to give equal thrust for balance at takeoff and can be rotated to give horizontal thrust forward or up and down or any direction using computer instruments

[0049] The Flying Disc Thrust Vectoring;

[0050] propeller or jet propulsion (with thrust vectoring) put on the airfoil pushing air in any direction using thrust vectoring vanes apparatuses at the circular wing perimeter using thrust vectoring which curve the air at required direction so the airflow will hit the start front edge and flow over the wing curvatures of the circular wing the Coand effect and hitting the trailer edge with its vanes flaps giving lift upward or any direction wanted using the thrust vectoring apparatuses due to the air being pushed on the circular wing and this can be done either using jet thrust vectoring or the propulsion or propellers with vanes flaps apparatuses.

[0051] At the perimeter of the circular disc on the rear edge of the circular wing, at least three or four or more fitted on the top or lower wing surfaces depending on its final use, equally spaced at the perimeter, thrust vectoring engines will be fitted all around the circular disc

[0052] In the present invention, the aircraft includes an inner upward fuselage structure to hold the surface wing with the inner cockpit body wing surface with an airfoil designed winglet to hold both inner and outer wing surface together in flight FIG. 7 & FIG. 8

[0053] Diverges with flexible elbow {(0-90) degree, straight or down} are used to divert the air pushing on the circular wing surrounding the propeller or the jet propulsion at suitable angle of attack on the circular wing or pushing the airflow away from the tail edge of the wing flaps straight or done hitting the ground if fitted on the rear tail edge to give maximum lift

[0054] Alternatively propellers or thrust vectoring or circular air duct fan can be used to push airflow directly on the circular wing leading edge

[0055] All types of flying discs, mentioned in this patent, civilian or military large or small bi-flying disc or mono flying discs can have any type of flaps or slats that will help the designer of the flying discs;

[0056] Flaps and Other High Lift Devices which can be Fitted to the Flying Machine Above as Follows FIG. 15;

[0057] 1) Blown flaps, or jet flaps, the flying disc can use these flaps all around the upper surface of the flying discs beneficially these blown flaps to power aerodynamic high-lift devices used on the wings of to improve their low-speed flight characteristics. They use air blown through nozzles to shape the airflow over the rear edge of the wing, directing the flow downward to increase the lift coefficient, Using jet exhaust or high-pressure air bled off of a jet engine's compressor and then redirected to follow the line of trailing-edge flaps

[0058] 2) The Junkers design is a slotted plain flap, where the flap is fixed below the trailing edge of the wing the flying disc can use these flaps all around the upper surface of the flying discs beneficially. This design allows airflow to pass between the wing and flap, even when the flap is retracted. Because of the increase in airflow, a significant increase in lift is added to the wings, even at slow speeds

[0059] 3) Leading edge slats and slots are mounted on the top of the wings' leading edge and while they may be either fixed or retractable, the flying disc can use these flaps at the leading edge all around the upper surface of the flying discs beneficially when deployed they provide a slot or gap under the slat to force air against the top of the wing, they offer excellent lift and enhance controllability at low speeds, flaps may be equipped with one or more slots to increase their effectiveness

[0060] 5) Spoilers are intended to create drag and reduce lift by spoiling the airflow over the wing. A spoiler can be retracted. Spoilers are usually installed mid chord on the upper surface of the Wing, but may also be installed on the lower surface of the wing as well

[0061] 6) Ailerons several may be fitted to flying disc equally spaced and are similar to flaps (and work the same way), but are intended to provide lateral controlwhen an aileron on one wing increases the lift, the opposite aileron does not, and will often work to decrease lift FIG.

[0062] 7) Plain flap at full deflection the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0063] 8) Double slotted Fowler flaps extended for landing the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0064] 9) Krueger flaps and triple-slotted trailing-edge flaps extended for landing the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0065] 10) Winglets, an upturned extension of airplane wings that reduces drag and improves fuel efficiency, the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0066] 11) Split flap, The rear portion of the lower surface of the airfoil hinges downwards from the leading edge of the flap, while the upper surface stays immobile, the flying disc can use these flaps all around the upper surface of the flying discs beneficially This can cause large changes in longitudinal trim, pitching the nose either down or up. At full deflection, a split flaps acts much like a spoiler, adding significantly to drag coefficient. It also adds a little to lift coefficient.

[0067] 12) Slotted flap, A gap between the flap and the wing forces high pressure air from below the wing over the flap helping the airflow remain attached to the flap, increasing lift compared to a split flap, the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0068] 13) Fowler flap A split flap that slides backwards, before hinging downward, thereby increasing first chord, then camber, the flap may form part of the upper surface of the wing, like a plain flap, or it may not, like a split flap, but it must slide rearward before lowering the flying disc can use these flaps all around the upper surface of the flying discs beneficially

[0069] Tests Carried Out by the Inventor on the Patent Principal;

[0070] Several successful flying Disc Tests on the flying patent principal were tested

[0071] Using several wing shapes using codes were tried to get best lift at best angle of air attack just before stall occurs

[0072] To get best lift characteristics balance were designed where the model where placed with small driving engine placed underneath the model and counterbalance was placed on the other arm at same distance from the center

[0073] When the engine starts weights is placed underneath the engine to keep the model at the same height level by putting weights to balance the lift after which the coefficient of lift is calculated using Bernoulli's formula assuming air has fixed density W=(LC)*(AIRd)*A*(v*2)

[0074] Good results were obtained using delta triangular segments to form circular wing FIG. 2 as described above but have sharp thick upper part of the wing copied from the wing code to gave maximum lift at wind angle of attack (12 deg) but the lower wing surface had straight surface at wind angle of attack approximately (12-45 deg) which gave good uplift results.

[0075] Confirmation tests were done to see if Airflow tends to stick to gently curved surfaces, a phenomenon called the Coand effect,

[0076] At the leading edge of the circular wing and at the trailing edge flat or curved pieces are attached to these edges with full control on them by the autopilot for stability and the pilot which will help to control the aircraft in any direction needed to go.

[0077] To give the aircraft much faster movement horizontally in 360 deg one or more propeller or jet can be fitted underneath the pilot cockpit or attached to the circular wing which will give the aircraft several degree of movement (360 deg and vertical movement).

[0078] Several possibilities can be added to the circular wings like slots curved starter edges and this circular wing will take all the fittings and the winglets that straight normal wings uses and will apply to this circular new wing

[0079] To stop gyro inertia rotation in the tests when using propeller two propellers turning in opposite direction (like some helicopters use) or several rotating gyroscopes were attached to the circular wing lower rim calculated to stop the inertia rotation

[0080] This aircraft can take off at any place and no need for airport at takeoff or landing and will take the roll of helicopter in vertical takeoff and fly horizontally like any other civilian aircraft and will have minimum drag due to its slender and rugged shape (dome shell) even when flying at high speed with fast movement in all direction

[0081] These prototypes aircrafts had 2-6 meter diameter and can be very large and carry several thousand passengers with very rigid shape and structure (shell shaped dome one of the strongest shapes in nature)

[0082] Landing on sea water is possible with necessary design adjustments, the Flying Machine can be designed to have all parts waterleaf proof with all adjustment to be a submarine with all hydrodynamic parts fitted and designed to submerge in water with the same shape of the flying disc
