The running, taking-off and landing aerocar can take off only by running on a road with a certain length, the cruising and flying energy consumption is low, but the occupied space is large after the wing is folded. In addition, the conventional flying automobiles are basically medium-high flying automobiles, flying at a height of hundreds of meters or kilometers can cause catastrophic consequences once a fault occurs, so that the requirements on the driving skills and psychological qualities of users are high, and people generally have worry about high-altitude flying, so that the popularization and application of the flying automobiles are difficult. Further, the higher the flying height of the hovercar is, the more the fuel consumption or the power consumption is, and the worse the economy is.
The ground effect is a wonderful aerodynamic phenomenon, namely when a moving object is very close to the ground (or the water surface), the pressure difference between the upper surface and the lower surface of the object is increased, the lifting force of the object is increased suddenly, and therefore the object can fly close to the ground or close to the sea. The electric ground effect flying automobile can run on a ground road and can realize ultra-low altitude flying of less than ten meters, and has the advantages of high safety, good economy, flexible and convenient use and very wide application prospect.
