    • PROBLEM TO BE SOLVED: To provide a propeller capable of achieving a high lift coefficient.
      SOLUTION: This propeller including one or multiple blades fitted to a shaft to be different in center generates free vortex in a fluid by dynamically changing a blade pitch. In the case of fetching energy of a moving fluid, while a fluid flow working on the blade rotates the propeller, a pitch change produces a fluid flow pattern known as Karman vortex street. The time average flow field resulting away from the propeller is a trailing field, and the energy of a fluid flow can be efficiently converted to the rotation of a shaft driving device. In the case of propulsion, the given shaft rotation and the dynamic pitch change in the fluid are joined to produce a flow pattern reverse to Karman vortex street. The propeller is suitable especially for a low flow velocity in terms of utilization of energy or propulsion. In the low flow velocity, owing to an effect of separation of flow caused by a low Reynolds number on the blade, it is inefficient in the other propeller.

    • 要解决的问题:提供能够实现高升力系数的螺旋桨。 解决方案:该螺旋桨包括一个或多个安装在轴上的叶片以不同于中心的螺旋桨,通过动态地改变叶片间距而在流体中产生自由涡流。 在获取移动流体的能量的情况下,当在叶片上工作的流体流动旋转螺旋桨时,沥青变化产生称为卡曼涡街的流体流动模式。 从螺旋桨产生的时间平均流场是拖尾场,流体流的能量可以有效地转换为轴驱动装置的旋转。 在推进的情况下,给定的轴旋转和流体中的动态俯仰变化被连接以产生与卡曼涡街相反的流动模式。 螺旋桨特别适用于能量或推进力的低流速。 在低流速下,由于叶片上的雷诺数较低引起的流动分离的影响,在其他螺旋桨中效率低下。 版权所有(C)2007,JPO&INPIT

    • Aeromobil is a dynamic flying machine heavier than air which produces necessary aerodynamic force for lift, thrust and control moments in aerodynamic generators. Flying characteristics of Aeromobil are those which make it possible for it to lift and land vertically in its own characteristic way, to soar in big altitude range, to take any direction in space by its vertical axle while soaring, to get to translational motion in any direction from every soaring position, to get into soaring position from every direction of translational motion, to turn around all three space axles simultaneously while soaring (it can be turned around side axle x for 360 degree, around vertical axle z for 360 degrees), and the aircraft can be turned around vertical axle y for 360 degrees in order of horizontal progressive motion whether in motion ahead or back. All flying characteristics are controlled by hydraulic system over Distributor of group change of angle of attack, Distributor of control by direction, altitude and laterally, Distributor of thrust vector, and Distributor of brake vector.

    • In some embodiments, a rotorcraft includes a fuselage (10), a tailboom (24), a drive system (38) and a variable thrust cross-flow fan system (32; 100). The cross-flow fan system (32; 100) includes a cross-flow fan assembly (102) that is mechanically coupled to a drive shaft (108) and operable to rotate with the drive shaft about a longitudinal axis. The cross-flow fan assembly (102) includes first and second driver plates (104, 106) having a plurality of blades (110a-110g) rotatably mounted therebetween. The blades are disposed radially outwardly from the longitudinal axis and have a generally circular path of travel when the cross-flow fan assembly (102) rotates about the longitudinal axis. The blades (110a-110g) are moveable between a plurality of pitch angle configurations. A control assembly (130, 134a-134g, 142a-142g) is coupled to the blades. The control assembly (130, 134a-134g, 142a-142g) is operable to change the pitch angle configuration of the blades (110a-110g) to generate variable thrust at a substantially constant rotational speed of the cross-flow fan assembly (102).
