- the aero-space used by (MTA) 20 and UAVs is to be called aero-traffic lower space, its height is to be nearly 3,000 meters, this space is to be divided into two: top part for big (MTAs) (Multiple task Aerocarriers) 20, and lower part: for UAVs/drones (unmanned aerial vehicles).
- FIG. 1- A Illustrates a 3-D general view for the (MTA) 20 as unmanned aerial vehicle, wherein the shape of the (MTA) 20 is specifically but not limitedly semi- cuboid with curved sides, chamfered edges and fillet corners, from the front right and left sides, it is supporting two front ducted propellers 21 with their swinging mechanism 22 and their duct exits 23 which are extending toward the rear side, the two front swingable ducted propellers 21 are installed near the front left and right corners of the (MTA) 20 while the rear ducted propellers 24 are installed inside the ducts 25 which are extending from their open inlets at the front to their exit swivel nozzles 26.
- Inflatable wings 27 are shown deployed and the landing wheels 28 are on landing configuration.
- FIG. 1- B Illustrates another embodiment with 3-D view for the (MTA) 20 general view as Unmanned aerial vehicle, wherein instead of using two rear ducted propellers 24 with two swivel nozzles 26, only one is used after converging and uniting the two inlet ducts 25 into one from their other rear half, while their front inlet shape stays the same as in FIG. 1 - A.
- the (MTA) 20 body 32 from all sides consists of aluminum or fiberglass plates fixed on metallic chassis 33 of bars and beams which are extending along the edges of the (MTA) 20 body 32, while the ducted propellers 21, 24 are in-housed by metallic ring carriers 34, while the inflatable wings 27 housing is supported with a 2D wing-shaped metallic frame 35.
- Fig. 2 illustrates the chassis 33 with some major parts.
- FIG. 3 illustrates a 3-D view for the (MTA) 20 on land, wherein the wings 27 are stowed, the wheels 28 are supporting the (MTA) 20 body 32, the swivel nozzles 26 are not shown here as they are regarded to be on vertical configuration on land, while taking-off and while landing.
- FIG. 4 (C - E) illustrates schematic views for the air directions at cruise mode, then switching from cruise mode to landing and finally at either landing or vertical take-off configurations, wherein during cruising the front ducted propellers 21 are on at horizontal configuration, the rear ducted propellers 24 are on too, with the air exiting them kept toward a horizontal direction via the nozzles 26, in total the thrust is in the horizontal cruising direction the same like in FIG. 5.

- Landing of the (MTA) is nearly 20 similar to the (MTA) take-off but here the wings should be stowed, the (MTA) 20 body 32 should fit to a road vehicle parking size, so the landing starts with wings 27 retarded or stowed and front ducted propellers 21 disengaged from their ducts 36 and rotated from horizontal to vertical position, to share with the rear nozzles 26 in supporting the landing of the (MTA) 20 via the vertical thrust, camera 37 (not shown) spanning the car parking location and the nearby moving vehicles should be installed, wherein here it is recommended to indicate on the parking itself that this is specified for (MTA) 20, so that no car park inside it, a placard 36 hung down may be used to warn other vehicles from getting under the landing (MTA) 20.
- FIG. 6 Illustrates another embodiment with a schematic view for the (MTA) 20, wherein instead of using two rear ducted propellers 24, only the front two ducted propellers 21 are used, while each of their ducts is divided into two, so a total of four sub-ducts 29 is created, such that the high speed air from each sub-duct 29 will exit either normally from opened nozzles (no swivel nozzles 26 are provided).
- a flat spring loaded outlets (SLO) 30 are provided and located horizontally from downside after one side of each sub-duct 29 and from the rear side before the exit of the remaining two other sub-duct 29 divisions, each SLO 30 will open like a gate downward by swinging 90° from horizontal into vertical.
- a rotatable circular plate 31 is installed horizontally to be in parallel with the air flow, while when it is rotated upward and become vertical, it will block the high speed air from exiting horizontally backwards, in such a case, the high speed air will press down on each SLO 30 which will open and direct the high speed air downward creating a thrust from four points to initiate the MTA 20 take off, once the MTA 20 reaches an enough height for cruising, it will rotate the rotatable circular plate 31 into a horizontal position, the air will flow in its normal direction horizontally backwards, while the SLOs 30 will close under the high retard tension of the springs.
- Note- 1 the rotatable circular plate 31 which is installed inside ducts and pipes to act like a valve is well-known as a conventional valves in the art, but it should be strongly supported by e.g a hydraulic mechanism to withstand the high speed air when it is blocking its exit.
- FIG. 7 illustrates a schematic view for the (MTA) 20 wings 27 stowing and retarded.
- FIG. 7- A- C illustrates a 3-D view for the (MTA) 20 wings 27 stowing embodiment in steps: two motors 39 are fixed in opposite sides of the (MTA) 20 top side edges, each motor 39 is connected to an opposite wing 27 via a string 40, when evacuating the wings 27 is started, instead of being hung down, the motors 39 will be initiated to pull the wings 27 from their far edges toward the motors 39 where the strings 40 are rolled, pulling the wings 27 in such a manner will stow them in a compact and neat manner onboard, where the width of the (MTA) 20 which was spanned via the wings 27 demolish to zero. It needs to be noted here, that wings 27 can be stowed too over any full-time cabin which is permanently installed onboard in some embodiments like in Fig.8.

As example in FIG. 1, the parts' features are arranged sequentially from number 20, 21, 22...
The aero-space used by (MTA) 20 and UAVs is to be called aero-traffic lower space, its height is to be nearly 3,000 meters, this space is to be divided into two: top part for big (MTAs) (Multiple task Aerocarriers) 20, and lower part: for UAVs/drones (unmanned aerial vehicles).
FIG. 1- A Illustrates a 3-D general view for the (MTA) 20 as unmanned aerial vehicle, wherein the shape of the (MTA) 20 is specifically but not limitedly semi- cuboid with curved sides, chamfered edges and fillet corners, from the front right and left sides, it is supporting two front ducted propellers 21 with their swinging mechanism 22 and their duct exits 23 which are extending toward the rear side, the two front swingable ducted propellers 21 are installed near the front left and right corners of the (MTA) 20 while the rear ducted propellers 24 are installed inside the ducts 25 which are extending from their open inlets at the front to their exit swivel nozzles 26. In addition, Inflatable wings 27 are shown deployed and the landing wheels 28 are on landing configuration.
FIG. 1- B Illustrates another embodiment with 3-D view for the (MTA) 20 general view as Unmanned aerial vehicle, wherein instead of using two rear ducted propellers 24 with two swivel nozzles 26, only one is used after converging and uniting the two inlet ducts 25 into one from their other rear half, while their front inlet shape stays the same as in FIG. 1 - A.
The (MTA) 20 body 32 from all sides consists of aluminum or fiberglass plates fixed on metallic chassis 33 of bars and beams which are extending along the edges of the (MTA) 20 body 32, while the ducted propellers 21, 24 are in-housed by metallic ring carriers 34, while the inflatable wings 27 housing is supported with a 2D wing-shaped metallic frame 35. Fig. 2 illustrates the chassis 33 with some major parts.
FIG. 3: illustrates a 3-D view for the (MTA) 20 on land, wherein the wings 27 are stowed, the wheels 28 are supporting the (MTA) 20 body 32, the swivel nozzles 26 are not shown here as they are regarded to be on vertical configuration on land, while taking-off and while landing.
FIG. 4 (A- B): illustrates a schematic view for the (MTA) 20 vertical take-off, wherein in Fig. 4-A the front ducted propellers 21 and the swivel nozzles 26 are on horizontal mode, when switching on both front ducted propellers 21 and the swivel nozzles 26 into vertical mode, the ducted propellers are pushed forward to disengage the ducts and swung up 90° so is direction is changed from horizontal to vertically upwards via two conventionally motorized swinging arms 23 located on both front right and left sides of the (MTA) body, the swinging arms are pushed forward hydraulically and rotated 90° (many available mechanisms in the art can be adopted to achieve this 90° movement) while the swivel nozzles 26 are rotated vertically downward in the same method mentioned in the prior arts. Switching on the front 21 and rear 24 ducted propellers allows the front propellers 21 to push the air in a higher speed downward creating a vertical thrust, while the nozzles 26 will guide the high speed air which is exiting the rear propeller duct 25, creating a rear vertical thrust, in total, both front and rear vertical thrust will initiate a four balanced air columns supporting the take-off of the (MTA) 20. It is clear in Fig. 4- B that there is no air passing the ducts of the front ducted propellers 21 during this stage.
FIG. 4 (C - E) illustrates schematic views for the air directions at cruise mode, then switching from cruise mode to landing and finally at either landing or vertical take-off configurations, wherein during cruising the front ducted propellers 21 are on at horizontal configuration, the rear ducted propellers 24
are on too, with the air exiting them kept toward a horizontal direction via the nozzles 26, in total the thrust is in the horizontal cruising direction the same like in FIG. 5. It needs to be noticed here that the thickness of the arrows indicates a high speed air exiting a ducted propeller. In the same Fig. 4- F illustrates arrows representation for the air flow direction and its speed change after exiting the ducted propellers 21, 24 on cruising configuration. Fig. 4- G illustrates arrows representation for the air flow direction and its speed change on either vertical take-off or landing configuration.
FIG. 5: illustrates a schematic view demonstrating the (MTA) 20 cruising mechanism, wherein after completing take-off to a suitable cruising height, the front tubular propellers 21 are swung by the side arms 23 to their horizontal position depending on either hydraulic or motorized conventional mechanism, where they will be pulled back to engage with the horizontal side ducts 36 as male to female, then a high speed air will be pushed outward from their rear side via these two ducts 36 exits 22, a vertical thrust will be created to push the (MTA) forward in addition to the low air pressure zones which are created front of the propellers 21, meanwhile the swivel nozzles 26 are turned to horizontal direction to provide an extra cruising thrust, where the (MTA) 20 will be on full flight mode. Landing of the (MTA) is nearly 20 similar to the (MTA) take-off but here the wings should be stowed, the (MTA) 20 body 32 should fit to a road vehicle parking size, so the landing starts with wings 27 retarded or stowed and front ducted propellers 21 disengaged from their ducts 36 and rotated from horizontal to vertical position, to share with the rear nozzles 26 in supporting the landing of the (MTA) 20 via the vertical thrust, camera 37 (not shown) spanning the car parking location and the nearby moving vehicles should be installed, wherein here it is recommended to indicate on the parking itself that this is specified for (MTA) 20, so that no car park inside it, a placard 36 hung down may be used to warn other vehicles from getting under the landing (MTA) 20. FIG. 6 Illustrates another embodiment with a schematic view for the (MTA) 20, wherein instead of using two rear ducted propellers 24, only the front two
ducted propellers 21 are used, while each of their ducts is divided into two, so a total of four sub-ducts 29 is created, such that the high speed air from each sub-duct 29 will exit either normally from opened nozzles (no swivel nozzles 26 are provided). To change the high speed air direction from horizontal into vertical, a flat spring loaded outlets (SLO) 30 are provided and located horizontally from downside after one side of each sub-duct 29 and from the rear side before the exit of the remaining two other sub-duct 29 divisions, each SLO 30 will open like a gate downward by swinging 90° from horizontal into vertical. After each of these SLOs 30 from their rear side, and from inside each sub-duct 29 a rotatable circular plate 31 is installed horizontally to be in parallel with the air flow, while when it is rotated upward and become vertical, it will block the high speed air from exiting horizontally backwards, in such a case, the high speed air will press down on each SLO 30 which will open and direct the high speed air downward creating a thrust from four points to initiate the MTA 20 take off, once the MTA 20 reaches an enough height for cruising, it will rotate the rotatable circular plate 31 into a horizontal position, the air will flow in its normal direction horizontally backwards, while the SLOs 30 will close under the high retard tension of the springs.
Note- 1 : the rotatable circular plate 31 which is installed inside ducts and pipes to act like a valve is well-known as a conventional valves in the art, but it should be strongly supported by e.g a hydraulic mechanism to withstand the high speed air when it is blocking its exit.
Note- 2: the SLO 30 can be actuated via many other conventional mechanisms.
The inflatable wings 27 deployment to a horizontal position is easily carried out; either from their on-board stowed position or their storable retarded position, it is no more than blowing air or gas inside them, while the motors 39 which pull them to a storing mode, will be releasing them here slowly until they take the shape like in Fig. 1. The most important part is illustrated in FIG. 7 (A, B) which illustrates a schematic view for the (MTA) 20 wings 27 stowing and retarded. FIG. 7- A- C: illustrates a 3-D view for the (MTA) 20 wings 27 stowing embodiment in steps: two motors 39 are fixed in opposite sides of the (MTA) 20
top side edges, each motor 39 is connected to an opposite wing 27 via a string 40, when evacuating the wings 27 is started, instead of being hung down, the motors 39 will be initiated to pull the wings 27 from their far edges toward the motors 39 where the strings 40 are rolled, pulling the wings 27 in such a manner will stow them in a compact and neat manner onboard, where the width of the (MTA) 20 which was spanned via the wings 27 demolish to zero. It needs to be noted here, that wings 27 can be stowed too over any full-time cabin which is permanently installed onboard in some embodiments like in Fig.8.
FIG. 7- D: illustrates general schematic views for the (MTA) 20 wings 27 retarding into accordion configuration, here the wings 27 are divided into equal areas along their lengths, each area is separated from its neighbor one via a normal strength wing inflatable material, while each area 41 itself is reinforced more than the separation zones 42 which run like belts in-between the reinforced areas 41. This design is made to make it easy to fold the wing into standing (rigid) pleats 43, such that when two parallel strings 40 are run via tubular sealed holes 44 running through each area, then pulling back these strings 40 via a conventional driving mechanism, will pull each reinforced area 41 rigidly as a pleat, while the flexible separation zone 42 in-between these areas 41 which is flexible will tilt the reinforced areas 41 either upwards or downwards to be arranged in accordion pleats 43, with more pulling, the pleats 43 are more pressed toward each other releasing their air, and retarded toward the (MTA) 20 side body 32 into their housings 45, where they are stored in a small space.
FIG. 8: illustrates a 3-D view for the (MTA) 20 with onboard cabin 46 body installed (Manned aerial vehicle), the onboard cabin can be taking a shape of a mini-bus, but to be called mini-airbus (MAB), the body here can be made of Aluminum and can be divided from inside into front cockpit, while the remaining room space can be used for the configurations which are illustrated in Figs (8- 12) as two option for the passenger seats positioning (Fig. 8), or carrying pacrcels which is to be received by local drones, or once the MTA approaches a destination its roof opens for inner drones provided with the MTA to unload it and deliver the parcels (Fig. 9) or to be used as an ambulance (Fig. 10) or to be
used for broadcasting for coverage from a height with a better view (Fig. 11) or to be used for vehicle / motor bike recovery service ( Fig. 12).
FIG. 13: illustrates a 3-D view for the (MTA) provided with onboard cage 50 for multiple technical services and uses such as: facade cleaning, fire fighting, painting, repair, maintenance of high rise buildings or structures and also MTA to drone parcel delivery. The cage 50 is installed for staff and their equipment safety and security, meanwhile providing easy access for carrying technical jobs from onboard of the MTA.
FIG. 14: illustrates a 3-D view for recovery service. FIG. 15: illustrates a 3-D view for carrying big shipments.
Finally: a city theoretical areal-tracks 48 (airways) divided in-between (MTAs) and UAVs: as the (MTA) and UAVs will create crowded air traffics without any solution provided in any invention, here the (MTAs) and UAVs are suggested to have identification numbers + registration plate numbers, each type of (MTA) or UAVs should have a flight level of height which it should not pass it up or down randomly, but should have inlet column 49 tracks for vertical take-offs towards their track levels, in the same they should have exit column 49 tracks 48 for landing, they will not stop suddenly inside their tracks 48 then to move vertically downward directly, but there should be sideway tracks 48 were they leave their original highway tracks 48 to lower down their speeds, then to move down through the recognized and organized theoretical track 48, until it is completely engaging to its track column 49 where it moves vertically down.
The same should be applied for the taking-off, U- turns, and turning right or left, theoretical track bridges should be introduced too to prevent crowded drones at the cross-sections.
So, for UAVs, police drones should have their own track heights, the same applies for parcel delivery drones, firefighting drones...etc, and in the same multiple height level tracks should be divided in-between the multiple types of (MTAs).
