Background

With the change of modern war forms, a single land battle mode is difficult to meet the military battle requirements of China, land military battle vehicles cannot cross obstacles in time within a limited time to transport fighters, and the maneuverability is poor in the current three-dimensional battle, while the continuous fighting capability of air combat equipment is weak. Therefore, it is necessary to provide a land-air flying vehicle capable of taking off and landing vertically, which not only has lasting land battle capacity, but also can realize rapid switching between different land and air forms, and can take off and land vertically in a narrow space, thereby greatly improving the battle strength of our army.

Chinese invention patents CN113370730A and CN113427954A both disclose flying cars capable of taking off and landing vertically and flying horizontally, the former has folding wings and two rotors on the wings, the latter has folding wings and two turbofan engines on the wings, but in the invention, because the wings are unfolded during taking off and landing vertically, the space required by taking off and landing vertically is greatly limited, and the wings are unfolded to have larger resistance during rising, thereby reducing the function of the rotors. The former uses a power battery to supply power, so the former does not have long-term working capacity, and the latter uses fossil energy to supply energy for the aerocar, so the reaction time in the flight process is short when abnormal conditions such as oil leakage occur, and although the thin film solar cell is equipped, the thin film solar cell is greatly influenced by weather and does not have long-term and stable working capacity.

The invention patent CN109878282A discloses a four-duct control vertical take-off and landing variant flying automobile, which is small and compact in structure, but is not suitable for bearing multiple persons because a riding space is hardly reserved in the design scheme, and meanwhile, the four-duct working mode designed by the scheme cannot meet the requirements of air cruising and accelerating rapid driving at the same time.

In addition, the prior art cannot meet the requirement of providing high-power-density power energy, and has the smooth operation capability of three action states of land driving, vertical take-off and landing and air flight.
