Abstract

In a diffrent way from systems used presently for transports and search for energy, the devices of the present invention set in revolution $g(V) elements (r) which, when rotating $g(v) at a characteristical angular speed and due to the phase difference of the law of action of masses along the flexible blades which compose them, generate a propulsion force (F) perpendicular to the centrifugal revolution force and with a linear intensity higher, after a certain lapse of time, than the alternating power consumed by the elements in the direction perpendicular to their translation. Both in this version and in the version using the induction of the gravity effects, these crafts make thus possible the propulsion of vehicles as well as the production of energy, cost free.

Description

a) - Method and propulsion assemblies using the oscillation of flexible blades driven in rotation in a force field. b) -The present invention relates to the propulsion of all mobile land, sea and space vehicles, as well as the production of new energy, both at fixed station, and to provide the energy necessary for the propulsion of the preceding mobiles, while One of the parts of this invention serves as a propellant. c) Up to now, the only mechanical means of moving is the wheel system, propellers which, constrained to rotate, by a motor system, use a reaction, with respect to the ground or with respect to a fluid. There is also the rocket propulsion system, which consists in expelling a gas mass, in order to benefit from the opposite reaction. In the latter case, and more particularly for the propulsion of spacecraft, beyond the Earth's atmosphere, we arrive at an upper speed limit, since, for long journeys, we must first take a mass of gas from more and more important, as one wants to arrive at an increasingly greater speed. It is therefore very interesting to be able to obtain an acceleration economically from an engine internal to the machine that we want to move. As for the problem of energy supply, it is obviously linked to the problem of the risk of an oil shortage. d) The device (I) has an external acceleration, coming from the arrangement of internal forces, which allows it to move outside a fluid, and without using the rocket propulsion system. In addition, under air vacuum, from v = o, at speed v, it has expended an energy kMv, and has an energy that is a

say greater than the energy consumed, from a certain speed in the direction of its propulsion. It therefore gives rise directly to the device (2), capable of recovering excess energy, that is to say of providing free energy, the advantage of which does not require argument. The devices (3) and (4) are modifications of the device (I), which, under the action of gravity, can respectively provide the same advantages as (r) and (2).

1 - According to Figs: (5, 6 and 7), a device (r), forming a rotor, is composed of flat spring blades (Lr), fixed rigidly at their end (C), to an axis (X), rotated, the end (U) of the blades (Lr) being able to vibrate without constraints. The flat spring leaves (Lr) have, according to Fig: (l), a length (L), a width (l), a thickness (e), and elastic properties, such as, rigidly fixed and immobile , by their end (C), and subjected to the force (B) in their free end (U), they return when the force ceases, at their starting point, and enter into oscillation, according to AB, at a frequency (f ), equal to the inverse of the travel time AB, BA; they have these properties in a movement perpendicular to (l), but are not flexible in a movement perpendicular to (e). If (e) is small compared to (l), this last characteristic is realized. Preferably, hardened steel blades are used.

Fig: 2, a rotor (r), set in rotation at the characteristic speed ω _1, ω ₃ , and subjected to the force ^F i, due to zero gravity, or to a centrifugal effect, its axis of rotation (x), being subtracted from ^F i, by the resistance of its support ^R i = - ^F i, is subjected to the force ^F x. nerυendi¬

The blades (Lr), according to a certain embodiment, are provided / at their end (u), with a ballast (m) formed by a metal counterweight. Calculation of the forces at play, according to Fig: 2. Let us consider the vector

The vibrations are transmitted perpendicular to

F m is the component of ^F i, according to

The impulse arrives at X, with a delay of _

In a rotor with 4 symmetrical blades, forming a 90 ° angle between them, for the second set of blades

In X ', F arrives with phase shift of

(m) being the mass of each blade, ^F i is the force applied to 4 m

One calculates, just as, with the forces of friction near, the average value of ^F r is:

The same effect is obtained with blades (Lr) not fitted with ballast (m); for the calculation of the effect ^F r obtained, we then consider the action of the forces ^F i on each of the parts d (m _j ), such that d (m _j ) = m _r , mass of the leaf spring.

The experiment is easy to carry out, by carrying out the assembly of Fig: 3. Two rotors (r) are rotated at the desired speed, using synchronous electric motors (31), connected to an alternating current generator . The motors are fixed on a rotor (R), using flanges (33); the rotor (R) turns relative to a chassis

(34), using bearings (35). The power supply is réa¬lized by ground and a carbon collector.

We observe the existence of the forces ^F r ₁ to ω ₁ and ^F r ₃ to ω ₃ , by the rotation of the support (R), the force ^F r, being quickly balanced by the friction due to the air.

Fig: 5 shows a rotor (r) with two blades (Lr), the length (L) of which is perpendicular to the axis (x), intended for slow rotational speeds (ω). Preferably the plane of the blades (Lr) formed from the flat of the blade (L × 1) is located in the same plane as the length of the axis of the rotor. When blades of smaller frequency (f) are used, that is to say if rotors (r) rotating at a slow speed ω are used, the elongation AB of the end (U) of the springs becomes significant. It is therefore interesting to use shorter or thicker blades, and rotors (r) rotating faster. In the case of high speeds ω, the centrifugal effect, due to the rotation of the rotor (r), creates harmful tensions on the springs. In order to subtract the flexion AB of the spring blades for this centrifugal effect, the blades (Lr) are preferably arranged, according to Figs: 6 and 7, so that their thickness (e) looks towards the axis of rotation ( X), and that their length (L), forms with the axis (X), an angle (α), such that, during their vibration AB, their distance UO, to the axis (X) is as constant as possible; the angle (α) is determined by the following calculation, according to FIG. 8.

The blade oscillates around the center 0. The position of the center O is determined experimentally by farting the maximum angle of inflection of the blade, UL, the radius of circle described by the blade during its bending, d the mean diameter of the pulley ( p), we set Y = U Sin δ L ^, experience shows that U is close to 0.87, (1-Cos δ)

The angles are such that

According to Fig: 6, representing a rofor (r) with two leaf springs (Lr), and Fig: 1, which represents a rotor (r) with four blades, the pulley (p), is produced in a cylinder, of diameter d ₂ , chamfered (6I), so that the chamfer line (62), forms with the axis (X), an angle the pulley is hollowed out at (63), so that

the face (64) is parallel to the diameter of the pulley, at the distance of this diameter, the number of recesses corresponds to the number

blades (Lr), which is provided with the pulley, which is pierced in its center, so as to receive the key (66) and the axis (X) threaded, provided with the nut (67); the plywoods (68) have a notch (9), of width (1) and depth (e), allowing the blades to be locked (Lr) they are pierced with holes (72), opposite the orifices made in the blades ( Lr) and threaded holes, made in the body of the pulley, intended to receive the screws (70); flat spring leaves (Lr) in hardened steel; are fixed on the faces (64) of the pulley, using the counterplates (68), and screws (70). The blades (Lr) may or may not be provided with a ballast (m) at their end, in order to increase the effect of the induction forces (F _i ).

For reasons of interference, between the different blades (Lr), the rotors (r), having two symmetrical blades, operate at two speeds, ω ₁ , and ω ₃ , while the rotors with more than two blades, are predestined at speed ω ₃ The device (3) ₅ according to Fig: 2, is thus produced; rotors (r) according to Figs: 5, 6 or 7, are arranged on a frame; their axes (X) of rotation are arranged horizontally and perpendicular to the desired direction of propagation; they are coupled to a system motor which drives them at a speed ω ₁ (mod .2π) or ω ₃ depending on the direction of the desired propulsion, under the action of the forces of gravity; the assembly is placed in an enclosure under vacuum. The chassis is fixed to the mobile to be driven horizontally. Calculation of the energies used.

The work provided, E _r , since the elongation a = 0 has power, P _r .

The triavail consumed consists of raising the mass (m), its elongation a ', maximum, against F _i , at each half turn.

l

a power, P _i ,

We see that from a certain time, the propulsion power is greater than the power consumed.

The device (4), according to 1a Fig: 3, makes it possible to recover the excess energy and therefore serves as an energy generator. The rotors (r) are coupled to a motor system which sets them in rotation as shown in Fig: 3, the rotors (r) are located at the ends of the main rotor (R), which can rotate around its vertical axis (Y); the axis of the rotors (r) is horizontal, and directed along a radius of the plane of rotation, perpendicular to the axis (Y), which can rotate relative to the enclosure, under vacuum, forming a frame (34 ), using plate bearings (35); the axis (Y) is coupled to an energy receiver, an alternator, allowing energy to be recovered in electrical form.

The device (I), according to FIGS: I0, II, I2, I3, makes it possible to obtain a propulsion, in the absence of the effect of gravity, it is preferred to the device (3), because it makes it possible to modulate the resulting thrust, by modifying the speed of rotation Ω of the main rotor (R), to obtain values of F _i clearly greater than mg, hence a power gain, and a better function of the rotors; the tendency to phase shift decreasing when F _i increases with respect to m. Rotors (r) of axes of rotation (X) are arranged on a main rotor (R) set in rotation, along its axis (Y) in an enclosure under air vacuum forming a chassis, the axes (X) are orthogonal to the axis (Y) and to a distance (D) from the axis (Y). The rotors (r), coupled to a motor system, rotate at the characteristic speeds, ω ₁ ω ₃ (mod 2π), capable of ensuring propulsion, the rotor (R), rotates at the speed Ω ensuring the production of forces

F _i , by the centrifugal effect. In one embodiment, the rotation of the rotors (r) and (R) is ensured by a single motor (I22) Fig: I2 the connection of the two systems being ensured by a system of axes and gears

) varies, the motors driving the rotors (r), are then fixed on the rotor (R).

The calculations are identical to systems 3 and 4, the propulsion power can exceed the power consumed, so we have to make an energy generator, device (2), which can operate in the absence of gravity, of higher power 'and modular, relative to the device (4).
