Description

本発明は、並進翼に関するものである。 The present invention relates to a translational wing.

従来一般に知られている流体流動制御装置としてプロペラまたはスクリューと呼ばれる回転翼がある。回転翼はブレードとブレードを回転軸に連結するハブとから構成され、ハブを回転中心としてブレードを回転させることによってブレードの運動エネルギーと流体の運動エネルギーとを相互変換する。回転翼の用途は広く、航空機・船舶などの推進装置、または送風機・ポンプなどの造流装置のように、ブレードの運動エネルギーを流体の運動エネルギーに変換する能動的な用途と、風車・水車などの発電装置のように、流体の運動エネルギーをブレードの運動エネルギーに変換する受動的な用途がある。 A conventionally known fluid flow control device is a rotor blade called a propeller or a screw. The rotor blade is composed of a blade and a hub connecting the blade to a rotation shaft, and the blade kinetic energy and fluid kinetic energy are mutually converted by rotating the blade around the hub. Applications of rotor blades are wide. Active applications that convert blade kinetic energy into fluid kinetic energy, such as aircraft and ship propulsion devices, or air flow generators such as blowers and pumps, and windmills and water turbines There are passive applications for converting fluid kinetic energy into blade kinetic energy.

回転翼の性能は、ブレードの形状、枚数、回転速度などによって決定される。これらの性能決定要因はブレードと流体とが効率よく運動エネルギーを相互変換するように最適化される。しかし、回転翼に求められる、軽量、小径、高強度などの設計要求はすべて運動エネルギーの変換効率を低下させる制約条件となる。回転翼はブレードの片翼端をハブに連結して回転するためブレードの翼端と翼根とでは回転速度が大きく異なる。また、回転翼のブレードには回転速度の二乗に比例する大きな遠心力が発生する。この回転翼の運動的特徴はブレードやハブの形状を複雑にさせ、運動エネルギーの変換効率を低下させる主な原因である。 The performance of the rotor blade is determined by the shape, number of blades, rotational speed, and the like. These performance determinants are optimized so that the blade and the fluid efficiently interconvert kinetic energy. However, design requirements such as light weight, small diameter, and high strength required for the rotor blades all become constraints that reduce the conversion efficiency of kinetic energy. Since the rotating blade rotates by connecting one blade tip of the blade to the hub, the rotational speed of the blade tip and the blade root are greatly different. Further, a large centrifugal force proportional to the square of the rotational speed is generated on the blade of the rotor blade. This kinematic characteristic of the rotor blade is the main cause of complicating the shape of the blade and the hub and reducing the conversion efficiency of kinetic energy.

本発明による流体流動制御装置はブレードの両翼端にローラーチェーン等の動力伝動輪を連結して長円軌道とし、ブレードの迎角を周期的に制御しながらこれらの動力伝動輪を連動して輪転させることによって流体の流動を制御する。 The fluid flow control device according to the present invention connects a power transmission wheel such as a roller chain to both blade ends of the blade to form an elliptical track, and these power transmission wheels are rotated in conjunction with each other while periodically controlling the angle of attack of the blade. To control the flow of fluid.

ブレードが長円軌道を並行して周回する流体流動制御装置を並進翼と呼ぶ。 A fluid flow control device in which a blade orbits an ellipse in parallel is called a translation blade.

並進翼はブレードが長円軌道を並行して周回するためブレードの周回速度は翼幅方向に一定である。したがって並進翼はブレードの翼型を翼幅方向に一定にすることができ、ブレードの全翼面で効率よく運動エネルギーの相互変換をすることができる。さらに並進翼はブレードを長尺にする、またはブレード数を増やして長円軌道を長くすることによってソリディティを最適な状態に保持したままで大型化することができる。 In the translation wing, since the blade orbits the ellipse in parallel, the rotation speed of the blade is constant in the blade width direction. Therefore, the translation blade can make the blade airfoil constant in the blade width direction, and can efficiently convert the kinetic energy between all blade surfaces of the blade. Furthermore, the translation blade can be enlarged while maintaining the solidity in an optimal state by making the blades longer or increasing the number of blades to make the elliptical orbit longer.

本発明による並進翼はブレードの迎角を安定して制御できることを特長とする。ブレードの迎角を安定して制御することによってブレードと流体の運動エネルギーを効率的に相互変換することができる。 The translation blade according to the present invention is characterized in that the angle of attack of the blade can be stably controlled. By stably controlling the angle of attack of the blade, the kinetic energy of the blade and the fluid can be efficiently interconverted.
