Abstract
The present invention relates to a scheme for improving efficiency of a flapping-wing aircraft, which acquires progressing force through swing in a fluid medium (air or water). In the field, bionic flapping wing aircraft is provided, but fails to catch the essence of energy efficiency of swing flying of insects, fish and birds. Therefore, the energy utilization efficiency of the flapping-wing aircraft in the prior art is not higher than that of fixed wing airplane. In order to greatly improve the energy efficiency of high flapping-wing aircrafts, the invention provides a scheme for high efficiency wing-flapping aircraft. The flapping-wing aircraft provided by the invention is characterized in that wing roots are connected to other parts of the aircraft by springs, so that the flapping wings have an intrinsic flutter frequency, and the system only needs to supplement energy dissipated by the flapping wings for power consumption in each flutter cycle to maintain flutter of wings. Thus, the scheme greatly reduces energy consumption and improves the energy efficiency of flapping-wing navigation. According to the invention, by means of flapping-wing aircraft, human being can realize high efficiency navigation like insects and birds.

The present invention is that a kind of raising is fluttered its wings up and down the scheme of aircraft usefulness, comprise fuselage, flutter its wings up and down, pressure sensor or acceleration pick-up, driver train of fluttering its wings up and down, rigidity of fluttering its wings up and down and quality adjustment mechanism, electronic-controlled System's composition, wherein, flutter its wings up and down and to be made up of wing bar, parachute, parachute is attached on wing bar, and Chi Gankeyou branch wing bar is connected with it, can be hollow tubular, it is characterized in that: fuselage is connected with fluttering its wings up and down, and the wing root of fluttering its wings up and down is connected with fuselage by spring; Or wing bar, parachute itself adopts elastomeric material manufacture; Or, bionical tadpole is fluttered its wings up and down machine of fluttering its wings up and down with fuselage pattern of fusion like that, the covering (parachute) of bionical tadpole adopts elastomeric material manufacture: fluttering its wings up and down or fuselage is being equipped with pressure sensor or acceleration pick-up, pressure sensor or acceleration pick-up are connected with electronic-controlled system, and electronic-controlled system is connected with quality adjustment mechanism with flutter its wings up and down driver train and rigidity of fluttering its wings up and down.
Flutter its wings up and down driver train in the past many by mechanisms such as double leval jib from wing root makeup energy, the strength problem due to material makes frequency be difficult to improve.
Driver train of fluttering its wings up and down of the present invention is formed by towards the hydraulic tubing of fluttering its wings up and down (the vein pipeline of bionical dragonfly) and pump, borrows " topping up---imbibition " circulation, to feeding of fluttering its wings up and down, supplements energy of vibration; Or driver train of fluttering its wings up and down is made up of the motor be arranged on wing bar and the oscillator that is connected with motor, and wherein, motor can be arranged on wing root position, oscillator can be arranged on wing wing bar slightly, to feeding of fluttering its wings up and down, supplementary vibrational energy; Or driver train of fluttering its wings up and down is made up of voice coil motor and oscillator, to feeding of fluttering its wings up and down, supplement vibrational energy; Or the oscillator that driver train of fluttering its wings up and down is driven by fluid line, pump and fluid motor is formed, to feeding of fluttering its wings up and down, supplement vibrational energy.
Oscillator can be eccentric wheel, mass; Oscillator also can be made into hollow body and recharges fluid, is connected with pressure cylinder by pipeline; Or oscillator also can be made up of the relatively-movable part of two or more.
Rigidity of fluttering its wings up and down and quality adjustment mechanism by pressure cylinder and coupled flutter its wings up and down on pipeline form, pipeline wherein can be wing bar: or, by linear electric motors, the position of oscillator moved, make the relatively-movable part of oscillator change position; Or, connected the Fluid Volume changing and fill in oscillator hollow body by pipeline by pressure cylinder.
The present invention is by rigidity and the quality adjustment mechanism of fluttering its wings up and down, and changes the rigidity or quality of fluttering its wings up and down, thus changes the natural frequency of vibration of fluttering its wings up and down.
The invention has the beneficial effects as follows, utilize and flutter its wings up and down and the natural frequency of fluid, system only needs at each period of vibration, supplements the energy that externally acting dissipates can maintain vibration of fluttering its wings up and down for fluttering its wings up and down, thus, significantly reduce system energy consumption, improve the efficiency of fluttering its wings up and down and flying.

Detailed description of the invention
As shown in Figure 1, oscillator (3) vibration driving eccentric wheel to form by motor (A), can be fed to wing bar (1), then drive parachute (2), make whole swing of fluttering its wings up and down by energy of vibration;
As shown in Figure 2, when after pump (5) circulation " suction---extruding " work, working fluid by according to some cycles to the bionical vein pipeline (4) " topping up---imbibition " on fluttering its wings up and down, quality of fluttering its wings up and down and rigidity produce cyclical variation, be subject to the combined action of gravity and fluid simultaneously, make whole swing of fluttering its wings up and down;
The signal that electronic-controlled system gathers according to pressure sensor or acceleration pick-up, regulate and control to flutter its wings up and down driver train and flutter its wings up and down rigidity and quality adjustment mechanism, makes the rigidity of fluttering its wings up and down or quality and oscillation frequency and amplitude reach optimum regime; The signal that analogy biological brain (electronic-controlled system) gathers according to nerve endings (pressure sensor or acceleration pick-up), commander's limbs (flutter its wings up and down driver train and flutter its wings up and down rigidity and quality adjustment mechanism) carries out action; Utilize and flutter its wings up and down and the natural frequency of fluid, system only needs at each period of vibration, supplements the energy that externally acting dissipates can maintain vibration of fluttering its wings up and down for fluttering its wings up and down, thus significantly reduce system energy consumption, raising is fluttered its wings up and down navigation efficiency.
Because the large span is fluttered its wings up and down the restriction of machine material ability to bear, the technical scheme that we can also adopt " breaking the whole up into parts; collection zero is whole ", fuselage is allowed to connect roof beam structure, roof beam structure is laid many fluttering its wings up and down, form the array of fluttering its wings up and down that the similar flying formation of geese is collaborative like that each other, the flutter its wings up and down practicality of aircraft of the large scale of construction is enhanced.
