2 Claims. (Cl. 170135) The present invention is directed to a lifting apparatus more eflicient and practical than the elevator used in helicopters at th'e'present time. 7
An object of the invention is to provide a horizontal side is presented in front and that of the left side is seen from the back.
FIGURE 2 is a view in elevation of a sustainer on the side toward the inside part of the fiy-wheel.
FIGURE 3 is a view of the hub of the fly-wheel in vertical section and showing the transmission system of the rotary impulse of the driving shaft to the shafts of the rotors.
FIGURE 4 is a view in elevation and in front of an isolated rotor.
FIGURE 5 is a section view of the rotor of FIG. 4 on section line 55.
The fly-wheel of this invention is constituted by a central hub from which an irradiating frame 11 forms a structure on which are attached the sustainer devices 12. The fly-wheel operates in a horizontal plane around an axial pivot 13 fixed in the upper part of an aerial vehicle. The hub of the fly-wheel seats on a platform 14 which is a part of the vehicle, and contacts at the upper part against the plate of a cap 15 crowning the axial pivot.
The sustainer devices mounted on the fly-wheel are placed symmetrically and equidistant on the peripheral line of its structure. In FIGURE 1, a fly-wheel is shown with only two sustainers but it should be understood that the fly-wheel may carry a larger number if it is conveniently required.
Each sustainer device is composed of a housing 16 and a rotor 17. The housing is cylindrically shaped with parallel base walls concavo-convex in shape. The housing is fixed to the structure of the fly-wheel on its concave base wall with the face towards the center of same.
The rotor has a central hub 18 which is of a truncated cone shape and is placed with the large base upon the inner side. On this hub three funnels 19 in a reclined position rest with their collecting months 20 opening forwardly facing the direction of the rotating movement. The rotation of the rotor is forwardly to the direction of the revolving motion of the sustainer device. The funnels are situated on the periphery of the hub in a symmetrical way and equidistant to each other and with the collecting mouths comprising the whole width of the hub. Each funnel extends from its collecting mouth towards the back, gradually curving and narrowing until it totally penetrates into the hub. The funnel has its narrow end 21 located on the inner side of the hub, immediately before the following funnel comes.
The narrow end 21 of the funnel is connected to a conduit 22 transferring the outlet mouth of the funnel to a point situated on the periphery of the rotor. At the point of connection to the funnel, the conduit has a bend which goes up the opposite side, bending again and going in a radial direction to the periphery, describing 1 Patented Aug. 4, 1964 ice a backward sagging curve, crosses the funnel which is above and its outlet goes to the upper part of the latter. 7 To avoid the conduit interfering with the operative action of the funnel which it crosses, the conduit is placed embedded into the external wall 24 of the funnel which at this point has a thickness equal to the width of the conduit. Due to the larger thickness of the external wall the funnel deviates internally at this point on the opposite side and for this reason the side walls 24 and 25 continue externally parallel from the collecting mouth up to the height where the crossing is produced.
The housing facing the direction of the revolving movement leaves the rotor uncovered with a large opening 26 comprising the whole peripheral ring in approximately three fourths of its height from top to bottom and extends itself on the side walls up to the height of the rotor hub. The housing has another opening 27 at the back which is smaller and is situated on the lower and external side, just corresponding to the place of passage of the outlets 23 of the rotor. This opening is projected towards the back by means of a conduit which follows the curvature of the base walls of the housing.
The rotor of each sustainer device is mounted on a shaft 28 the extension of which, on both sides, goes through the center of the housing, thus giving to it a free support. The main portion of this shaft extends towards the center of the fly-wheel, crossing its frame within the cavity of one of its arms 29, arriving at the hub 10 of the fiy-wheel which gives it free admission until it reaches an inner chamber 30. The rotor shaft 28 is connected within this chamber by means of a pinion 31, which meshes with a gear 32 on the upper end of a vertical tubular shaft 33. This tubular shaft is mounted on the fixed axial pivot of the fiy-wheel which extends downwardly until it penetrates the aerial vehicle. This tubular shaft has mounted thereon a gear 34 meshing with another gear 35 mounted on a driving shaft 36.
By means of these connections the rotative movement of the driving shaft 36 is transmitted to the rotors 17, of the sustainers 12. The rotors execute their rotative movement forwardly in the direction of their revolving movement imparted by the rotation of the fly-wheel. The action of the rotors is regulated by the housings which allow an admission of atmospheric air in the most appropriate way. The action developed by the rotors will create a combined force of impulsion forwardly and upwardly. The forward impulsion will make the fly-wheel move in rotative movement carrying with it the sustainers attached to its periphery giving to them a revolving movement. The upward impulsion will make the fly-wheel move upwardly too, carrying with it the aerial vehicle attached to it.
The above mentioned operation takes place as follows: The operative elements are the funnels of the rotors. Each funnel when moving from top to bottom at the frontal opening 26 of the housing catches the air found in its way. The air when penetrating in the funnel suffers a compression due to the gradual narrowing of the funnel, passing then to the conduit where momentarily it is slowed due to the curves and inclination of same. This slowing allows the air to accumulate in the inner part and when it increases takes a fresh impulse for passing the second elbow and passes to the next section of the conduit. In this section the air under the pressure of centrifugal force advances and is ejected out just when the outlet 23 of the conduit passes in front of the sector where the backward opening 27 of the housing is situated. Due to its impusion the air goes out through this opening. The resistance that the air will oppose due to its inertia property when it is compressed and transferred downwardly will produce the raising force and the resistence that will oppose when it is transferred backwardly will create the advance force.
