Abstract

A kind of stretchable and retractable aircraft wing driven by screw rod. It is composed of motor, screw rod, light pole, driving buckle, driven buckle, front support rod, outer support rod, tail support rod and wing skin. The motor drives the driving buckle, driven buckle and tail support rod through the screw rod. The tail support rod drives the outer support rod to drive the folding and unfolding movement of the single side wing of the aircraft. The single side wing of the aircraft has flexible folding and unfolding function, so that the aircraft is suitable for more flight attitudes and motion in small space. The invention with opposite symmetrical structure is installed on the same aircraft. The light pole provided in the invention has the function of balancing the torsion of the driving buckle and the driven buckle ring screw rod. The invention is an improvement on the wing of the inventor's previous invention "a helicopter with a rotating chair", which makes the invention more superior in energy saving and flight and motion ability.

Description

Technical Field

[0001] This invention relates to aircraft, and more particularly to the design of wings for small manned aircraft. Background Technology

[0002] Existing aircraft all have fixed wings. Currently, only toy aircraft have movable wings. However, those are only "flapping" type movable wings, meaning they are movable wings that propel the aircraft forward by flapping their wings. Summary of the Invention

[0003] This invention provides "a screw-driven, extendable and retractable aircraft wing": It comprises a screw, a guide rod, an active latch, a driven latch, a front strut, an outer strut, a tail strut, aircraft wing skin, and a motor. The motor is mounted on the front base plate of the wing. The screw is formed by the motor shaft. The other end of the motor shaft is loosely connected to the tail base plate of the wing. Both ends of the guide rod are fixed to the front and tail base plates of the wing, respectively. One active latch and two or more driven latches are connected in series on the screw and guide rod. The active latches are arranged facing upwards at the tail of the wing. The two or more driven latches are arranged sequentially towards the nose of the aircraft, with the active latch as the base point. The active latch is equipped with a hook-and-chain mechanism to hook the active latch to the tail strut. The driven latches are equipped with skin edge latches that fasten to the edge of the wing skin.

[0004] The motor, screw, guide rod, drive buckle, driven buckle, front strut, outer strut, tail strut, and wing skin are generally on the same plane.

[0005] On the same aircraft, there is a pair of symmetrical left and right wings with opposite structures. The screws and guide rods symmetrically arranged on the left and right wings are based on the center line of symmetry of the entire aircraft. On the symmetrical left and right wings with opposite structures, the guide rods are located on the inside and the screws are located on the outside.

[0006] The driving fastener has one threaded hole and one through hole. The threaded hole engages with the threads on the screw. The through hole loosely fits the outer diameter of the guide rod. The driven fastener also has two through holes with approximately the same spacing as the threaded hole and through hole on the driving fastener. The through holes on the driven fastener loosely fit the outer diameters of both the screw and the guide rod.

[0007] The joint between the front strut and the outer strut is connected by a front joint shaft with a slip-fit ​​connection, and the joint between the outer strut and the tail strut is connected by a tail joint shaft with a slip-fit ​​connection.

[0008] After one active buckle and one or more passive buckles are installed on the screw and the guide rod, the active buckle and one or more passive buckles can form a pair or more opposing surfaces. A fixed buckle is provided at the center of each opposing surface, and the fixed buckles are connected by one of the following components: a soft rope and a chain of not less than one centimeter in length, so that the active buckle and passive buckle strung on the screw and the guide rod form a whole.

[0009] The wing skin also contains one or more wing ribs. These ribs are long, rod-shaped structures with different sized ends. The multiple ribs are installed side-by-side. After installation, the larger end of the wing rib faces forward and upward.

[0010] The design of the wings of the manned aircraft as retractable movable wings is a major breakthrough in aircraft wing design.

[0011] Designing the wings as movable wings can greatly reduce the overall size of the aircraft, thus enabling the aircraft to move in extremely small spaces. During flight, the wings can be extended and retracted in real time according to the actual needs of the airflow, which is conducive to gliding, hovering and high-speed maneuvers, thereby achieving the goal of high energy efficiency and high flexibility.

[0028] Reference Figure 1 The motor 8 is fixedly mounted on the front base plate 7. The tail end of the screw 11, which is composed of the motor shaft, is loosely connected to the tail base plate 14. The two ends of the optical rod 9 are fixedly mounted to the front base plate 7 and the tail base plate 14 respectively. The optical rod 9 and the screw 11 are installed side by side in the longitudinal direction of the aircraft.

[0029] Reference Figure 2 , Figure 3 and Figure 4 and refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 12 , Figure 13 , Figure 14Active buckles 13 are fitted at the tail ends of screw 11 and guide rod 9. Two or more driven buckles 10 are sequentially mounted forward and upward from the active buckle 13.

[0030] The active buckle 13 has two holes: a screw hole and a smooth hole (see...) Figure 7 , Figure 8 , Figure 9 and Figure 10 The screw hole engages with the screw rod 11, while the smooth hole loosely matches the outer diameter of the smooth rod 9.

[0031] Each driven buckle 10 has two holes with a spacing matching that of the screw holes and the optical holes on the driven buckle 13. The two optical holes are loosely fitted to the outer diameters of the screw rod 11 and the optical rod 9, respectively.

[0032] One end of the active buckle 13 is provided with a hook chain mechanism 15 that is connected to the tail support rod 16. One end of the driven buckle 10 is provided with a skin edge buckle 18 that hooks onto the skin edge 12 of the wing skin 3.

[0033] The wing front strut 6 is fixedly mounted on the front base plate 7. The wing front strut 6 is connected to the wing outer strut 2 via a front joint shaft 5. The wing outer strut 2 and the wing tail strut 16 are connected via a tail joint shaft 1.

[0034] The motor shaft (screw 11) is driven by a motor, which in turn drives the active buckle 13. The active buckle 13 pulls (when the wing is deployed) or pushes (when the wing is retracted) the driven buckle 10 via a soft rope or chain fixed to the fixed buckle, causing the buckle group formed by the active buckle 13 and the driven buckle 10 to move together with the active buckle 13, thereby realizing the action of retracting or deploying the wing.

[0035] The wing skin 3, including the wing ribs 4, is fitted onto the front strut 6, outer strut 2, and tail strut 16, and secured by the driven buckle 10. The tail strut 16 and the driving buckle 13 are loosely connected by a hook-and-chain mechanism 15. The back panel is bolted to the fuselage back panel through the back panel mounting holes 21. The back panel is the outermost panel on the fuselage back, serving to cover, protect, and decorate the components below it. The size of the back panel is approximately equal to that of the fuselage back.

[0036] exist Figure 12 , Figure 13 and Figure 14 As can be seen above, the cabin 24, the front base plate 7, and the tail base plate 14 are all mounted on the aircraft back panel.

[0037] pass Figure 11 You can see the nose 20, the rotor 19, and the wing skirt 22. Figure 11 The number 23 in the original design refers to the location of the fan hole 23 in this invention.

[0038] When the wings are folded, the overall shape of the aircraft is triangular, making the whole aircraft look like a realistic big bird.

[0039] The sequence of actions when the wings are deployed is the reverse of when they are retracted. When the aircraft wings are deployed, they resemble a large bird in flight.

[0040] Figure 11 This is a rear view of the entire aircraft when the wing is modified to "a screw-driven extendable and retractable aircraft wing" as described in this invention. The tail section 28 is directly fixed to the back panel.

[0041] Figure 13 26 indicates the fastening direction, and 27 indicates the skin tensioning direction. Figure 2 , Figure 3 , Figure 4 17 in the diagram represents the trajectory line of the tail joint axis. Figure 2 , Figure 3 , Figure 4 It can also be seen that the position of the active buckle 13 changes synchronously with the tail joint axis 1.

[0042] This invention comprehensively improves the aircraft's maneuverability in space, especially in confined spaces. It enhances the need for multi-attitude and energy-saving maneuvers during flight, and also improves flight flexibility.
