Definitions
- the invention relates to the principle and the realization of a motorized flying machine, used as toy or drone at very low cost, the flight of which is made autonomous by means of an onboard automatism, and possibly associated with a remote control device.
- the state of the art does not present remote-controlled flying toy whose flight is autonomous.
- the dexterity required for piloting, for example, a remotely controlled miniature helicopter precludes its use by children, especially in fenced areas.
- the object of the invention consists in producing a flying toy or a military observation drone in an urban environment, the flight of which is made static and stationary at a fixed altitude in the absence of instructions from the optional remote control.
- remote controls for motorized flying vehicle either by radio or by infrared. They emit in direction of the motorized toy in particular instructions of acceleration or direction.
- Remote controls lack responsiveness, they do not take into account the inertia of the flying machine nor the effect of the wind.
- the state of the art comprises the document WO2006 / 076743A which describes a rotating contract double-helix flying toy which maintains its constant altitude by means of a ground distance detection system comprising a coaxial optical transmitter and receiver.
- WO2004 / 027434 discloses a helicopter provided with optical image sensors which control the position of the center of gravity in order to drive it automatically. This document comes out of claim 1.
- the invention aims to solve these constraints, and realizes a flying machine whose flight is autonomous.
- the machine a helicopter, is stable at fixed altitude in the absence of command.
- the helicopter is provided with a residual permanent rotation compensation system.
- the altitude of the helicopter is stable, by means of a servo which regulates its distance to the ground.
- the helicopter avoids the obstacles by means of a servo which directs it in a direction free of obstacles.
- the helicopter does not rotate permanently, by means of a servo which acts on its orientation.
- the helicopter advances in a regular manner in its axis, by means of a balance which generates a horizontal forward component of the lift of the propeller (s).
- FIG. 1 represents a front view of the helicopter with two independent counter-rotating propellers.
- FIG. 2 represents a side view of the helicopter with two independent counter-rotating propellers.
- Figure 3 shows a principle view of the side of the helicopter with two contra-rotating propellers engrainées in reverse.
- Figure 4 shows the side view and top of the principle of processing sensor signals for controlling the motors.
- FIG. 5 shows the electronic block diagram of this treatment.
- FIG. 1 represents a front view of the helicopter with two counter-rotating propellers 11 and 12, respectively motorized and symmetrically controlled by each of a motor 16, and an amplifier device 15, which processes a signal emitted by an optical receiver 14, which signal is proportional to the retro-scattering of the light emitted towards the ground by the transmitter 13.
- FIG. 2 shows likewise and on the side said propellers 11 and 22, one of the motors 16 controlled by an amplifier device 55 and a sensor 14, and a transmitter 13, but also a battery 28, which provides the autonomous power supply, a tail 29 which stabilizes the flight.
- the center of gravity G is located in the vertical plane of symmetry of the helicopter and slightly shifted forward, so that the lift has a horizontal component forward.
- the helicopter comprises for each helix 11, 12, a transmitter of lunrvière 13 for example non-limiting infrared, a light receiver 14 for example non-limiting infrared, one and the other oriented towards the ground at 45 ° forward and 45 ° towards the ground.
- the receiver 14 is associated with a filtering system and discriminates the retro light diffused by the ground.
- This discriminator is for example a filter of an otic nature favoring the optical wavelength of the transmitter and filtering the others, or of an electronic nature, a modulation filter associated with a privileged frequency.
- the signal proportional to the back-scattered light is processed and amplified by an amplifier 15 and then converted into proportional control of the motor 16, which engages on a toothed wheel 17.
- the speed of the motor is proportional to the sum of the retro-scattered amplitude and its derivative, so it is maintained at a constant altitude, and damped the altitude oscillations.
- the motor 16 associated with 13, 14 and 15 located at the front right of the helicopter control the propeller 11 in rotation in the clockwise direction.
- the sensors and motors on the front left side controls the rotation of the propeller 12 in the counter-clockwise direction.
- an obstacle detected on the front right side results in an increase in signal reception, and an acceleration of the helix 11 which rotates clockwise.
- reaction the helicopter rotates counter-clockwise and changes its trajectory accordingly to avoid the said obstacle.
- the toy application of the helicopter is an original means of ensuring the safety of fragile household objects, and also an original mode of remote control in which the child interposes on the trajectory to modify it, and follows the helicopter when this trajectory is suitable.
- the heat detection will be done by sensors according to the state of the art, and the transmission of detection by a radio transmitter, the detector helicopter will then be signaled by the emission of powerful optical flashes embedded in the 'helicopter. The detector helicopter will then become the marker of a suspicious heat source, such as a flashing beacon.
- the helicopter has only one engine at the front 16 for the lift, but also a steering motor 32 and also a gearing 31 which reverses the speeds of the two propellers, whose rotations are connected.
- the progression of the helicopter is always associated with the center of gravity offset in front of the axis of the two propellers.
- the direction of propagation is modified and controlled by the motorized propeller 32.
- FIG. 4 represents the helicopter in plan view and side view
- the obstacle and altitude detection signals are always delivered by a transmitter associated with a receiver located at the right front 44 and at the front. left 45 respectively, emitting and receiving in the right front and left front respectively, 45 ° laterally and 45 ° to the ground.
- control of the lift motor 46 is processed by a summing device 41, and the control of the orientation motor 42 is processed by differentiator 43.
- the motor 42 turns the helicopter clockwise as soon as the signal 44 is greater than the signal 45.
- FIG. 4 gives an overview of the treatment of the signals 44 and 45, with the summator 41 realized by an operational amplifier 516, two summing resistors 511 and 512, a differentiating filter 513 and 514 for the damping of the altitude oscillation and a resistance to the gain 515, all supplied to the engine 46. the differentiator 43 to the motor 42, with two filters di f férentiados 524, 523, and two gain control resistors 525 and 526.
- the circuit may also include a device for canceling the authorization of the helicopter 530, which acts as an integrator. The rotation of the helicopter is detected by the closure of a 3-state switch 531, controlled by the helicopter tail drift, mounted on two pivots 534.
- the closed switch will change the voltage at the terminal of the capacitor 532, which will shift a slowly varying voltage source 530, which delivers an offset voltage to the device 525.
- This offset voltage has the effect of controlling the motor 42 to cancel any residual permanent rotation of the helicopter, and thus compensate for any balance faults in the right and left processing lines.
- the helicopter is of conventional structure, comprising a single horizontal helical propeller, and a single vertical tail propeller, opposing the autorotation, the speed of the one and the other being linked by a proportional function.
- the speed of the carrier helix is a function of the sum of the amplitudes of the retro signals diffused by the ground, and the speed of the tail propeller is modified, as a function of the difference between the amplitudes of the backscattered signals. by the ground
