Description

【発明の詳細な説明】 ロータ 本発明は、流れている流体からエネルギを吸収するため及び/又は流れている流 体にエネルギを放出するためのロータに関し、このロータは、ハブと少なくとも 一つのロータブレードから成る。[Detailed description of the invention] rotor The present invention provides a method for absorbing energy from a flowing fluid and/or for absorbing energy from a flowing fluid. Regarding the rotor for discharging energy to the body, this rotor has a hub and at least Consists of one rotor blade.

このようなロータは技術において広範に使用されている。例えば、流れている流 体からエネルギが風車で吸収され、近づいてくる風のエネルギはこの風車によっ て回転エネルギに変換され、これは発電機で電力に変換される。流れている流体 のエネルギは、例えばカブランタービンで回転エネルギに変換される。最後に、 ガスタービンが知られている。このガスタービンは多数のブレードを有し、これ らのブレードによって、膨張するガス流のエネルギが回転エネルギに変換される 。Such rotors are widely used in technology. For example, a flowing stream Energy from the body is absorbed by the windmill, and the energy of the approaching wind is absorbed by the windmill. is converted into rotational energy, which is converted into electric power by a generator. flowing fluid The energy is converted into rotational energy by, for example, a Kablan turbine. lastly, Gas turbines are known. This gas turbine has a large number of blades, which These blades convert the energy of the expanding gas stream into rotational energy. .

他方、ロータはエネルギを流れている流体に放出するのにも使用される。これは 、例えば、乗り物を駆動するために行われる。例としては船舶用スクリュープロ ペラ及び航空機のプロペラが挙げられる。エネルギを流れている流体に放出する ためのロータの他の機能は、流体を混合することである。このような場合、ロー タはいわゆる撹拌部材を構成する。On the other hand, rotors are also used to release energy into the flowing fluid. this is , for example, to drive a vehicle. For example, marine screw pro Examples include propellers and aircraft propellers. release energy into a flowing fluid Another function of the rotor for is to mix fluids. In such cases, the low The stirrer constitutes a so-called stirring member.

上述の全ての分野において、ロータの形状を適正にすることによってロータの有 効性を改善するための努力が長い間材われてきた。In all of the above-mentioned fields, the effectiveness of the rotor can be improved by optimizing the shape of the rotor. Efforts have long been made to improve efficacy.

本発明の目的は、冒頭に記載した種類のロータを、ロータが流れている流体から エネルギを吸収するために使用されるものであるか或いは流れている流体にエネ ルギを放出するために使用されるものであるかに関わらず、ロータの効率が更に 改善されるように改良することである。The object of the invention is to provide a rotor of the type mentioned at the outset from the fluid through which it is flowing. used to absorb energy or add energy to a flowing fluid The efficiency of the rotor is further increased regardless of whether it is used to emit It is to improve so that it can be improved.

本発明によれば、この目的は請求項1の特徴部分によって達成される。請求項I の特徴部分によれば、少なくとも一つのロータブレードは少なくとも一つの空気 力学的及び/又は流体動力学的波形を有し、この波形はロータブレードの平らな 部分とともに二つの縁部を構成し、半径方向流が近づく縁部はロータブレードの 縁部の垂線から角度αだけ傾斜しており、そのため、前記縁部は回転方向にある ロータブレードの縁部から外方に延び、他方の縁部はロータブレードの縁部に直 角である。According to the invention, this object is achieved by the characterizing parts of claim 1. Claim I According to the characteristic part of the at least one rotor blade, the at least one air having a mechanical and/or hydrodynamic waveform, which The edge along with the radial flow approaches the rotor blade. is inclined by an angle α from the edge perpendicular, so that said edge is in the direction of rotation extending outwardly from the edge of the rotor blade, with the other edge directly at the edge of the rotor blade. It is a corner.

本発明によるロータの効率の増大は、以下の通りに物理的に説明することができ る。この目的について、一方ではエネルギ製造システムを、他方ではエネルギ放 出システムを考えなければならない。エネルギ製造システムには、例えば風ター ビンが含まれる。エネルギ放出システムは、例えば船舶用スクリュープロペラ及 び空気推進プロペラを含む。エネルギ吸収システムでは、a−タブレード上を通 って外方に流れ去る空気又は流体要素に加わる遠心力により外方に流れ去る水が 波形により形成された障害物に衝突する。波形の前縁が適切に傾斜させであるた め、流体の半径方向流の一部がこの縫に沿って流れ去り、かくして追加の駆動成 分をつくりだす。本発明に従って設計したロータは、このましい圧力状態、即ち 過圧及び減圧、を生じ、これらもまた好ましい方法で駆動運動に変換される。The increase in rotor efficiency according to the present invention can be physically explained as follows. Ru. For this purpose, energy production systems on the one hand and energy release systems on the other hand. We have to think about the exit system. Energy production systems include wind turbines, e.g. Contains bottles. Energy release systems can be used, for example, in marine screw propellers and and air-propelled propellers. In the energy absorption system, the The air flowing outward due to the centrifugal force applied to the fluid element or the water flowing outward due to the centrifugal force exerted on the fluid element. Collision with obstacles formed by waveforms. The leading edge of the corrugation should be properly sloped. Therefore, a portion of the radial flow of fluid flows away along this stitch, thus creating an additional drive. create a portion. A rotor designed in accordance with the present invention has the desired pressure conditions, i.e. Overpressure and underpressure are generated, which are also converted into drive movements in a favorable manner.

エネルギ放出システムでは、波形が構成する障害物は、これらが実際に流れを集 中させる点で有効である。これは、流れの半径方向外方に差し向けられた成分が 単に流れ去ることのないようにし、この成分を連続性により軸線方向及び接線方 向に差し向けられると理解することができる。その結果、本発明の存在を確認し 、かくして効率もまた改善されるような方法で軸線方向成分が強化される。近づ いて(る流体が接触する面積及び周囲流体と接触した面積は約10%増大するが 、これに対し、流れ面積はこれと同時に増大されない。In an energy emitting system, the obstacles that the waveforms make up are the ones that actually collect the flow. It is effective in neutralizing the situation. This means that the radially outwardly directed components of the flow This component should be kept axially and tangentially by continuity so that it does not simply flow away. It can be understood that it is directed towards the person. As a result, the existence of the present invention was confirmed. , thus the axial component is strengthened in such a way that efficiency is also improved. approach (The area in contact with the surrounding fluid and the area in contact with the surrounding fluid increase by about 10%. , whereas the flow area is not simultaneously increased.

本発明によりつくりだされる特に望ましい結果は、ロータが液体流体中で回転す ることにより生じるキャビテーションが太き(減じられ、はぼ完全になくされる ということである。気体流体中で回転するロータでは、邪魔な騒音の発生もまた 実質的に減じられる。このような場合、流れがブレードの縁部で砕けることは本 発明が提供する空気力学的及び/又は流体動力学的波形を持たないロータよりも 遥かに高速で起こる。A particularly desirable result produced by the present invention is that the rotor rotates in a liquid fluid. The cavitation caused by That's what it means. Rotors spinning in gaseous fluids also produce disturbing noise. substantially reduced. In such cases, it is normal for the flow to break at the edges of the blades. than a rotor without the aerodynamic and/or hydrodynamic corrugations provided by the invention. It happens much faster.

本発明の所望の特徴によれば、空気力学的及び/又は流体動力学的波形及び残り のロータブレードには段が付加的に設けられている。こうした段は、適切には、 ロータの目的に応じて形成されている。例えば、ガス流の場合、これらの段は比 較的細かいのがよいが、水流の場合、これに相応して粗くなっている。ガス流の 場合でも、流速に応じて更に粗い段を備えるのが望ましい。According to a desired feature of the invention, aerodynamic and/or hydrodynamic waveforms and residual The rotor blades of are additionally provided with stages. These stages are suitably The rotor is formed according to its purpose. For example, in the case of gas flow, these stages are It is better to be relatively fine, but in the case of water flow, it should be correspondingly coarse. gas flow Even in this case, it is desirable to provide coarser stages depending on the flow rate.

本発明の更に他の所望の特徴は、ロータブレードの半径方向内方に配置された部 分が平らなままであるのに対し、ロータブレードの外側部分に本発明に従って形 成された空気力学的及び/又は流体動力学的シャフトが設けられているというこ とである。このような場合、半径が増大する場合にのみ強い遠心力が作用し、ロ ータブレードの半径方向内側領域には遠心力が生じないという事実が1酌されて いる。Still other desirable features of the invention include a radially inwardly disposed portion of the rotor blade. The outer part of the rotor blade is shaped according to the invention, whereas the outer part of the rotor blade remains flat. This means that an aerodynamic and/or hydrodynamic shaft is provided. That is. In such cases, a strong centrifugal force acts only when the radius increases, and the rotor Taking into account the fact that no centrifugal force occurs in the radially inner region of the motor blade. There is.

本発明によるロータの好ましい使用は実施態様項から明らかになるであろう。Preferred uses of the rotor according to the invention will become clear from the embodiment section.
