The application discloses an electromagnetic force direct driving type dragonfly imitating flapping wing aircraft platform and a flight control method thereof, and relates to the technical fields of bionic aircraft and electromagnetic driving control. The aircraft platform comprises a body, front and rear flapping wing groups, a wing-body connecting rod, an electromagnetic driving device and a main controller. The electromagnetic driving device is composed of a driving shell, a permanent magnet and a transmission connecting rod. The main controller adjusts the amplitude, direction and frequency of the driving current of the conductive coil, generates electromagnetic force to drive the flapping wing to reciprocally flap, and realizes the controllability of the amplitude, direction and frequency. The method establishes a target speed and equivalent frequency mapping in a manual mode, calculates a frequency error based on the feedback of an inductive device, and adjusts the driving current parameters through a PID closed loop. In a target navigation task, path planning, image acquisition, obstacle detection, straight flight or obstacle avoidance branches and heading correction cycles are executed. The scheme has fast response and compact structure, and can realize stable hovering, sensitive steering and autonomous navigation.

This invention discloses a dragonfly pineapple AfATL6 This research, encompassing gene cloning methods, expression vectors, and their applications, falls under the field of biotechnology. Specifically, it involves extracting total RNA from dragonfly pineapple, reverse transcribing it to synthesize cDNA, using this as a template to design specific primers, and then employing PCR to obtain... AfATL6 The CDS of the gene was ligated into the pEASY-blunt vector, transformed into E. coli Trans-T1 competent cells, and positive clones were selected to obtain the Dragonfly Pineapple. AfATL6 The gene, whose full-length CDS is 1242 bp, encodes a protein containing 414 amino acid residues. This invention utilizes transient expression and fluorescence microscopy to detect... AfATL6 The subcellular location of the gene-encoded protein is the cell membrane. Through transgenic technology, it was discovered... AfATL6 Gene overexpression delayed flowering in Arabidopsis thaliana and provided a yeast two-hybrid assay to verify the interaction between the AfATL6 protein and AfGF14i, a key component of the florigen-activating complex. AfATL6 Obtaining the gene laid the foundation for studying the flowering mechanism of dragonfly bromeliads and has important theoretical and practical significance.

This invention relates to the field of biomimetic flapping-wing aircraft technology, and discloses a multi-degree-of-freedom biomimetic dragonfly flapping-wing aircraft, including a fuselage and transmission device, a left flapping wing and a right flapping wing, a flight control and communication module, and a tail wing steering mechanism. The fuselage and transmission device include a drive gear, an intermediate transmission gear, a driven gear, a first rotating shaft, a left flapping wing rocker arm, a right flapping wing rocker arm, a second rotating shaft, a retaining ring, a transmission link, a gearbox frame, a fuselage main beam, a drive motor, and a high-definition camera. The flight control and communication module includes a flight control system housing, a battery, a receiver, a brushed ESC, and a flight control board. The tail wing steering mechanism includes a servo mount, a servo servo, a servo output rocker arm, a steering lever, a limit seat, a tail wing, and a tail wing drive link. This multi-degree-of-freedom biomimetic dragonfly flapping-wing aircraft can reduce the overall size and weight of the aircraft, while providing more convenient tail wing steering, thereby achieving flexible control of various flight attitudes and improving the usability of the aircraft.

This invention discloses a biomimetic dragonfly flapping-wing aircraft with adjustable sweep amplitude driven by an air source, belonging to the field of aircraft technology. It includes: a base plate support, a transmission mechanism, a sweeping flapping mechanism, a pair of front flapping wings, and a pair of rear flapping wings. The transmission mechanism includes a front air source driven transmission mechanism and a rear air source driven transmission mechanism with identical structures located on the front and rear sides of the base plate support, enabling differential sweeping movements of the two pairs of flapping wings. Each flapping wing root is equipped with an adjustable sweeping flapping mechanism and a micro-gear. The front air source driven transmission mechanism drives the sweeping support to rotate circumferentially via an air source rotating blade engine, which in turn drives the flapping wings to sweep through a sweeping swing frame. The amplitude and speed of each flapping wing's sweeping movement can be controlled independently. During flight, the sweep amplitude or speed of the front and rear flapping wings on the same side can be controlled to be greater than that of the front and rear flapping wings on the other side to achieve turning movements and tailless flight control.
