The invention discloses a new method for controlling lifting force of an aerovane fan and a helicar utilizing this method. The method directly controls airflow rate of a turbofan using an airflow valve that can be opening or closed by a rotating operation thereof so as to control lifting force. The airflow valve has double layers, is perforated and shaped as a hemisphere or hemiellipsoid. A simple and practical helicar is designed on the basis of this method. In the helicar, a turbofan with double wings rotating in opposite directions with each other is disposed uprightly at the center part of the helicar; an array of spouts and an array of barrier sheets for adjusting airflow are arranged on a bottom plate; auxiliary wings that can be foldable and retractable are disposed on two sides; double vertical wings (and a rudder), a horizontal wing (and a lifting rubber) and a tailing spout are provided at the tail part of the helicar; an engine is placed at the rear part of the helicar; a driver chamber and a passenger chamber are placed at the front part of the helicar; and furthermore, a series of operation mechanism is included. The blades of the aerovane are fixed at an angle of attack, fixedly connected with a hub, strong as a whole, rotating at a high speed and have a small diameter. Therefore, the structure of the helicar is simple and compact. After the winds are retracted and folded, the width of the helicar may be about 2 meters, which is suitable for a drive on the road and a fly in the air (when an inflatable rubber bulb is attached to the bottom plate, the helicar also may land on the surface of water and drive on it. |
