Abstract
The patent describes the construction of a flying platform in the shape of a square, diamond or another geometry figure. It has a constant cross-section profile providing aerodynamic lift. This structural solution offers the possibility of flight in any of four directions; each corner could be the front corner of the flying platform. The aerodynamic lift is generated by air turbulences formed on the leading edges and resulting from the air flow disturbances. The design combines two features: the wing/fuselage profile and the shapes of square or diamond. It is characterized by longitudinal and transverse flight stability.
Description
FLYING PLATFORM WITH CONSTANT CROSS - SECTION PROFILE FOR EXPLOITING AIR TURBULENCES PHENOMENON
The subject of the invention is a portable video telecommunication device, data tra nsmission method, in particular audio/video data, and their application . People always wanted to rise into the air like birds that accompanied humankind since the dawn of time. One of the first litera ry descriptions is the story of Deadalus and Icarus. Many daredevils tried to repeat the feat unsuccessfu lly. In today's world Wright Brothers are deemed to be the aviation pioneers who in 1903 constructed the first successful powered airplane (based on the experience of Otto Lilienthal's gliders) that flew 36m . Aviation technology has been developed since then . In the following decades the development of aviation led to flights at high altitudes reaching the tropopause. The development of aircraft structures and their constituent parts such as wings (the shape of their wings), wing flaps having a strong impact on their performance have already been carefully developed 2, 3, 4
Presented in the patent US4, 015.787 technical solution shows the possibility of increasing wing aerodynamic lift at subsonic and supersonic speed by the movable auxiliary a irfoil insertion . Its use increases the wing lifting para meters and provides use of a simple control . The sa me way of increasing wing lift is described in the patent US6, 923.403 Bl .
The U .S. Patent 3,785,595 describes DELTA -shaped wing structures designed for use in aircraft flying at high speeds. An aircraft equipped with this kind of wings requires long takeoff and landing runways.
Described solution includes a pair of auxiliary controlled surfaces or wings pinned on the front surface of delta wings. This solution increases the aerodynamic lift at low speeds, and acts as a horizontal flight stabilizer.
The phenomenon that allows the air to keep flying objects such as airplanes or gliders is the use of the aerodynamic lift (underpressure) created by variable wing profile.
Since planes started to fly faster and higher they have been experiencing an adverse phenomenon called turbulence. For last 50 years of the twentieth century there was a variety of researches and studies on explaining and/or reducing the phenomenon . In order to avoid problems arising from the airflow around the wing - turbulence, wings are made of materials with spotlessly smooth surface. Works to increase the mechanical strength of wings in addition to design solutions were also focused on the use of new materials. Patent 5,735,486 shows the use of fiber- re info reed plastic composites. Bringing the wing to perfection leads to minimizing the phenomenon of turbulence on the roughness. The minimization of aerodynamic drag leads to the reduction of parasitic turbulence which reduces the aerodynamic lift and speed . Another method to get rid of turbulence is to minimize the cross-section of the aircraft, reducing to a minimum the amount of all aircraft components 3. A sample use of this phenomenon is presented in the patent PL3404697. It presents a device to increase the aerodynamic lift, which is provided with adjustable position flaps and nozzles. This solution offers an increased aerodynamic lift of a wing profile by installing additional equipment. It is merely an attempt to improve the design aimed at increasing turbulence, which according to the authors causes vortices responsible for increasing wing aerodynamic lift.
All of the above described solutions concern the improvement of aircraft design solutions, which aerodynamic lift is created by variable
cross-sections (profile) wing / wings.
The flying platform design consists of a single part, the "wing" . The shape of the wing as a whole has an external contour form of a square, rhombus (Figure 1 ) or other geometric figures. The vertical drop shows that it has a unique profile with a constant cross-section (Figure 2), giving it the lift and, most importantly, the ability to fly (creating aerodynamic lift) in two opposite directions. This is a feature that allows the model to fly in four directions : each corner could be the front corner of the flying platform . The aerodynamic lift is generated by air turbulence resulting from the bearing surface, caused by the air flow disturbance at the leading edges. Changes of flight direction are preceded by moving the drive and balancing the platform . At present, it is done manually before the flight, but the tries to change the center of gravity implemented automatically during flight have already been started. The control system operates with four faces on each edge, and (optionally) center of gravity controller.
The platform model is characterized by a very large bearing plane on which i.e. photovoltaic cells, providing power to the electric engine, can be mounted . During the tests the model (platform) has excellent stability (both longitudinal and transverse), a very large capacity, a very short takeoff and landing distances (STOL) and (due to the aerodynamic lift) very high speed range from Vmin to Vmax. An additional important feature is the simple production technology of the platform . The controls are located at the contours of the plates or will not be used at all in this form in case of the center of gravity steering applied . Traditional materials such as composites, laminates, etc are used to construct the platform . Existing technologies such as bonding, and, if necessary, screwing, riveting, etc. can be used to install/mount the components and pa rts. The model stands out a
completely new plane profile (constant cross section), and- a mpljetely■■'new, shape; The design combines these . two features i.e.5 - the airfoil profile and the shape of a square or diamond stands out excellent flight characteristics compared to the currently used solutions. '
