MODES FOR CARRYING OUT THE INVENTION

[0044] The present aerodynamic apparatus operates as follows (FIGS. 1-30).

[0045] The main structural components of the apparatus consist of three spherical bodies (17, 19, 20) (FIG. 1, 2, 17, 21, 22). The spherical structures are essentially rigid lifting bodies (17, 19, 20) connected to each other by means of fastening means (18, 21) (FIG. 17, 21, 22) which locks the position of the spheres relative to each other and capable of exchanging the dynamic loads of various elements located within the apparatus as well as of receiving the dynamic loads from the external environment around the apparatus.

[0046] The internal body (20) is a rigid lifting structure containing the following units (FIG. 1, 2).

[0047] The main fan with the drive motor (1) and supporting means of the main fan (2) having aerodynamic blades capable of blowing air in the required direction (FIG. 1, 2).

[0048] The primary rotary wing (3) made in a petal-like shape with the annular rotary means of the primary rotary wing (4) provided with the motor (with drive assemblies) of the annular rotary means of the primary wing (5) and supporting members of the primary rotary wing (6) (FIG. 1, 18, 19), transfers the force interaction of the airflow and the primary rotary wing (3) to the rigidly connected bodies (17, 19, 20). The primary wing (3) takes the airflow from the main fan (1) and generates lifting force by virtue of such air properties as continuity, compressibility and viscosity. The process of air flowing around the primary rotary wing (3) creates a low-pressure area on the upper surface of the wing (3) and a high-pressure area on the lower surface which generates on the wing (3) a resultant transverse force directed to the axial axis O-O. The supporting means (6) transfer the force interaction of the airflow and the wing (3) to the internal body (20) and then, through the powered fastening means (18, 21), they transfer the force to the middle body (19) and the external body (17) of the apparatus.

[0049] From the side of the trailing edge of the primary rotary wing (3) on the surface of the internal body (20) there is an opening (FIG. 1, 2) connecting spaces and for the operating medium and regulated by the middle body rear bypass valve (15) controlled by the motor (with drive assemblies) of the rear bypass valve of the middle body (16) (FIG. 9, 10). When the rear bypass valve of the middle body (15) is open (FIG. 10, view V, b) some amount of the air heated in space goes to the surface of the evaporator with the throttle valve of the cooling facility (29) rigidly mounted in space (FIG. 2, 17). The evaporator with the throttle valve of the cooling facility (29) are two (the first and the second) of the four main units of the cooling facility and make part of the system controlling the operating medium temperature. The cooling facility also has the third and the fourth main units, such as the compressor of the cooling facility (28) rigidly mounted in space a (FIG. 1, 17) and the condenser-radiator of the cooling facility (30) rigidly mounted on the rear outer hemisphere of the external body (17) whose pipelines are blown over with the free air (FIG. 2). The locations of the other inessential auxiliary standard members of the cooling facility are of no crucial significance and, therefore, are not shown in figures. (It is commonly known (Chumak, I. G., Chepurnenko, V. P. Cooling facilities.Moscow: Agropromizdat, 1991, P. 12, P. 495) that a refrigerating unit consists of four main parts: an evaporator, a throttle valve, a compressor and a condensate). As a result, the heat-generating operating parts of the apparatus are cooled by the atmospheric air moving inside the apparatus with the assistance of the cooling facility.

[0050] Along the axial axis of the main fan with the drive motor (1) there is a peripheral fan (with the drive motor) (22) rigidly mounted in coaxial alignment (FIG. 1, 2, 12, 17).

[0051] Air heating in the internal space also results from the action of friction forces between air layers and mechanical parts touching the high-energy air which continuously receives energy from the blades of the fans with drive motors (1) and (22). The greatest heating of the air in the internal space occurs when the opening, which is shut by the controlled rear bypass valve of the middle body (15), is closed (FIG. 9, 10). In so doing, due to simultaneous operation of the drive motors of the fans (1) and (22), the air from the main fan (1) goes towards the primary rotary wing (3) and, after passing it, comes to the blades of the periphery fan (22) that directs the airflow towards the main fan (1) along the internal surface of the internal body (20) retaining the direction of the airflow rotation that was prior imposed on it by the main fan (1). The air attracted by the centrifugal forces and the viscosity forces to the inner surface of the inner body (20) travels to the area hereinafter referred to as the main fan entrance area located between the front bypass valve of the middle body (26) and the rotation plane of the main fan (1) blades. After that, the airflow turns back, passes the main fan entrance area and gets into the operating area of the main fan rotating blades (1). Then the airflow gets another force impulse from the operating fan (1) and comes to the primary wing (3). Thus, within the inner space , due to continuously repeating cycles, it is possible to accelerate the air to high speeds and, by doing so, to generate a great lifting force on the primary wing (3), nevertheless, the air involved in the process is heated.

[0052] In space , along the axial axis of the main fan with the drive motor (1), there is a front bypass valve of the internal body (23) (FIG. 1), driven by the motor (with drive assemblies) of the front valve of the internal body (24) (FIG. 1, 6) that allows for controlling the air travel from space to space (when the rear bypass valve is open (15) (FIG. 10, view V, b), it is used for taking the air cooled in space by means of the evaporator with the throttle valve (29)), such being the case, on the surface of the internal body (20) there is a seal of the internal body front bypass valve (25) (FIG. 1, 7, 8) which, when for the closed position of the internal body front bypass valve (23), allows for proper pressurization which prevents the air travel from space to space .

[0053] In the direction of the flow of the operating media, coming off the primary rotary wing (3), along the fans axial axis (1, 22) on the middle body (19), there is a rear shutter valve (13) (FIG. 2, 13, 14) driven by the motor (with drive assemblies) of the rear shutter valve (14) (FIG. 16) and used to control the air travel from space to the atmosphere. The closed position of the rear shutter valve (13) is shown in FIG. 13, view D, a; the open position is shown in FIG. 14, view D, b.

[0054] The outgoing air comes to the petal-like steering rotary wing (7) (FIG. 1, 2) located along the axial axis of the fans (1, 22) behind the rear shutter valve (13), having an annular rotary means of the steering rotary wing (8) (FIG. 1, 15) and provided with the motor (with drive assemblies) of the annular rotary means of the steering rotary wing (9) (FIG. 2, 15) and the steering rotary wing supporting means (10) transferring the force interaction between the airflow and the steering rotary wing (7) to the external body (17). The steering wing (7) is mechanically connected with the bearing structural components of the apparatus andtogether with the primary wing (3)is used to create force control moments for the aircraft controlled and stabilized flight in the air space. Moreover, the air going to the atmosphere, generates reactive that contributes to the apparatus translational motion.

[0055] Along the fans axial axis (1, 22) in space a there is a front bypass valve of the middle body (26) (FIG. 1, 3, 4, 5) driven by the motor (with drive assemblies) of the front bypass valve of the middle body (27) (FIG. 1, 3, 4, 5) and used to control the air travel from the atmosphere to spaces and , consecutively. The closed position of the front bypass valve of the middle body (26) is shown in FIG. 4, section F-F, a; the open position is shown in FIG. 5, section F-F, b.

[0056] The free air coming into the apparatus, due to the process of suction, compression and thickening, normally results in condensate formation, therefore the apparatus is provided with a condensate collecting and draining system (11) (FIG. 1, 2, 20) located in the inter-body spaces of the apparatus. By means of a drain pump with a discharge tube (12) of the condensate collecting and draining system (FIG. 12, 20), the condensate is discharged into the atmosphere.

[0057] The middle body (19) contains the attitude orientation system (33) (FIG. 11) and the automated control system (34) (FIG. 11).

[0058] The lower part of the external body (17) of the apparatus contains a steerable landing gear (31) (FIG. 1, 17, 23, 24) provided with landing gear motors with drive assemblies (32) (FIG. 1, 17, 23, 24). In such a case, for the landing gear retracted position, the lower part of the external body has an indention (FIG. 1, 23, 24), in such a manner that with the help of the indention, the retracted landing gear (31) fits the external body structure minimizing the external body (17) friction drag while moving in the atmosphere. The landing gear (31) receives the control commands from the attitude orientations system (33) and from the automated control system (34) and changes the opening angle of its units, which secures the apparatus assigned position on the support surface (such as ground), depending on the slope or the density of the support surface.

[0059] To secure a stable and safe flight in the air, provision is made for a certain sequence in the operation of the apparatus units at each stage of take-off, evolution (various manoeuvres) in air and landing on the rigid supporting area. In so doing, from the moment of take-off to the moment of reaching a safe altitude, it is necessary to ensure that the design allows for complying the requirementswith respect to the centre of mass of the apparatus, the sum of all the moments of the aerodynamic forces generated by the airflow inside the apparatus, secures the position of the axial axis (O-O) parallel to the horizon of the take-off site taking into account the operation of the automated control system (34) and the attitude orientation system (33).

[0060] At the stage of take-off, the landing gear (31) should ensure that the position of the apparatus vertical symmetry plane should be square to the horizon of the take-off site, while the horizontal cross plane, including the axial axis O-O, should be parallel to the take-off site horizon. At the starting moment, the plane of symmetry of the primary wing (3) and the steering wing (7) should agree with the apparatus vertical symmetry plane, while the bypass valves (15, 23, 26) and the rear shutter valve (13) should be closed. The air in the internal space is circulated by the simultaneous starting of the main fan with the drive motor (1) and the peripheral fan with the drive motor (2). The air, first under the action of the rotating blades, travels from the main fan (1) in the internal space interacting with the primary wing (3), and then comes to the rotating airfoil blades of the periphery fan (22) that direct the air along the inner surface of the internal body (20). When this takes place, the air is retained in this part of the internal body (20) by the centrifugal forces and the viscosity forces of the air washing the inner surface of the internal body (20). In so doing, the peripheral fan (22) keeps the rotation direction of the airflow imposed by the main fan (1). From there, the air goes to the main fan entrance area, interacts with the specially designed airfoil blades of the main fan (1), gets another force impulse, and, at a high speed, directs to the surface of the primary wing (3), after which the cycle begins to repeat. After that, the motor (27) opens the front bypass valve of the middle body (26) and the free air, though the annular opening in the rear hemisphere of the external body (17), passing in the space through the openings in the front bypass valves of the middle body (26), goes to the main fan entrance area, gets into the operating area of the rotating blades of the main fan (1) and joins the dynamic process of the air motion in the internal space . Here, due to increased air density, the air mass is growing and the energy potential of the process is rising, which is very important at take-off, for example, in high mountains. As the air temperature is growing, the cooling facility starts to operate, and, at the same time, motor (24) opens the front bypass valve of the internal body (23) and motor (16) opens the rear bypass valve of the middle body (15). In so doing, the air heated in the cyclic process, is moving from the internal body (20) to the inter-body space and, blowing around the evaporator with the throttle valve of the cooling facility (29), begins to cool off. After that, the cooled air, through the annular opening formed by displacement of the front bypass valve of the internal body (23), enters the main fan entrance area, mixes with the air in the internal body and the free air coming from through the front bypass valve of the middle body (26), and from there the mixed air continues to participate in the cyclic process in the internal body . The cooled air that that comes in the manner described above, reduces the overall temperature of the air participating in the cyclic process in the internal space .

[0061] As the speed of the airflow above the upper surface of the primary wing (3) grows, the pressure difference on the upper and the lower wing surfaces (3) grows too, which generates on the wing surface area (3) a lifting force, that is transverse to the flow. For certain speed values of the airflow interacting with the primary wing (3), the lifting force is greater than or equal to the weight of the apparatus.

[0062] At the moment when the lifting force counterbalances the weight of the apparatus, the motor (14) begins to open the rear shutter valve (13) and the high-energy air from the internal space begins to flow out into the atmosphere interacting with the underlying surface of the steering rotary wing (7). The automated control system (34), taking into account the intensity and direction of the crosswind acting on the external body (17), issues a control command to the motor of the annular rotary means of the rotary wing (9) to change the position of the steering rotary wing (7) so that to generate a transverse force on the rotary wing (7) that would turn the apparatus around the vertical axis, which is passing through the centre of mass of the apparatus against the horizontal component of the crosswind, while the reaction force generated by the airflow going from the apparatus, should fully compensate the force of the crosswind horizontal component acting on the external body (17). Having generated a lifting force equal to its own weight and having compensated the crosswind action in terms of direction and force, the apparatus is ready take off. Speeding up the motors of the main fan (1) and the peripheral fan (22) generates a lifting force exceeding the weight of the apparatus and switches it to the take-off mode. Taking into account the environmental conditions, take-off site and wind direction, the automated control system (34) of the apparatus brings the target take-off trajectory to the required altitude and controls the speed of fan motors (1, 22), the position of the primary (3) and the steering (7) rotary wings and the other units of the apparatus. Having reached the safe altitude, the position of the apparatus axial axis (O-O) can be arbitrary and should correspond to the control program. Since both the primary (3) and the steering (7) wings built into the annular rotary means (4) and (8), respectively, are able of 360 degree rotation around the axial axis O-O, these wings (3, 7), by interacting with the rate-controlled windstream, are able to produce the required composition of control force moments with respect to the centre of mass of the apparatus in such a way that the apparatus is capable of intended evolutions (various manoeuvres) in air using the controlled reaction force of outgoing the high-energy air.

[0063] Depending on the current information coming from the attitude orientations system (33) (in the general case, these are: space coordinate values, linear and angular speeds accelerations of the aerodynamic apparatus), the information on the environment conditions (in the general case, these are: air density and temperature, wind direction and strength), and on the application tasks, by controlling the rotation of the main fan motor (1), the peripheral fan motor (22), the motor of the annular rotating means of the primary wing (5), the motor of the annular rotating means of the steering wing (9) as well as the motors (14, 16, 24, 27) controlling the operation of the rear (13) and the bypass (15, 23, 26) valvesthe automated control system (34) moves the apparatus along its path in the three-dimensional space, as well as accelerates or decelerates its motion along this path, including full stop (hovering).

[0064] An important feature of the apparatus is its ability, while controlling the operation of the bypass valves (15, 23, 26) and the cooling facility, to control the air density and temperature and, in so doing so, to optimise the process of generating lifting force, reactive thrust and motion control. This ability makes it independent of the altitude of the take-off or the flight. Take-off and flight are possible in the conditions very tenuous air of high mountains or very hot air of deserts. Due to the units that control the air density in the internal space and participate in the process of generating lifting force and control moments, it is possible to obviate the need for high-aspect wings when flying at high altitudes where the air is exceedingly tenuous. Owing to the latest systems of flight data acquisition and processing, the present system of the apparatus motion control reduces the speed of closing on the landing point to reasonably small values and ensures landing on any relatively even surface as well as on the water. In so doing, the aforesaid systems will be similar for both heavy and light apparatuses.

[0065] Moreover, building a complex apparatus consisting of two, three or more units of the present invention, makes it possible to build load-lifting vehicles, both automatically controlled and man-controlled, with common system of life support and control. Such load-lifting vehicles can be provided with transporting pallets combined into a single load-carrying structure as shown in FIG. 30.

[0066] Unlike common rotary-wing vertical take-off and landing aircraft, the present invention has considerably extended and simplified capabilities to build various means of rescue and emergency landing.

[0067] To optimise some design characteristics of the apparatus with the aim of eliminating the disadvantages of the conventional analogs, the standard design-theoretical methods and model tests established in fluid mechanics (Encyclopedic Dictionary of Physics/ed. by A. M. Prokhorov.Moscow: Sovetskaya Entsiklopedia, 1983.928 p.; Krasnov, N. F., Aerodynamics. Part I. Theoretical Framework. Airfoil and Wing Aerodynamics. Technical college textbook.Moscow, Vysshaya Shkola, 1976.384 p.; Krasnov, N. F., Aerodynamics. Part II. Aerodynamics Technology. Textbook for technical college students.3rd edition, revised and enlarged.Moscow, Vysshaya Shkola, 1980.416 p.) have revealed the following.

[0068] Other things being equal, the ratio of the internal surface radius of the external body to the internal surface radius of the middle body R.sub.1/R.sub.2 is ranging from 1.06 to 1.65; while the ratio of the internal surface radius of the middle body to the internal surface radius of the internal body R.sub.2/R.sub.3 is ranging from 1.03 to 1.55; see FIG. 2.

[0069] Other things being equal, for the chords , lying on the corresponding planes of symmetry of the wings (3, 7) and having the maximum dimensions, the ratio between maximum dimension of the primary rotary wing chord and the maximum dimension of the steering rotary wing chord B.sub.1/B.sub.2 is ranging from 0.59 to 18.5; see FIG. 2.

[0070] Hence, it was found that the proposed ranges are optimal. In other cases, beyond these optimal ranges, the efficiency of utilizing the air flow power used for generating the wing resultant lifting force, declines by at least 15%.
