The invention relates to the field of unmanned aerial vehicle control application, in particular to an unmanned aerial vehicle flight system capable of hovering through a foreign object and a long-endurance unmanned aerial vehicle. The flight system comprises a PCB object carrying platform, a helium balloon, a propeller, a brushless motor, a sensor group, a remote control module, a flight control module and a power battery; the flight control module receives motion attitude and displacement information from the sensor group and expected displacement information from the remote control module, then calculates voltages which should be distributed by brushless motors of the four propellers, and transmits signals to the corresponding brushless motors respectively, so that air pressure differences are formed by controlling the respective rotating speeds of the four propellers, and the flight control module controls the four propellers to rotate. Lifting and horizontal and circumferential flight of the unmanned aerial vehicle are realized by using the air pressure difference; the flight system is applied to the long-endurance unmanned aerial vehicle. By arranging the helium balloon, the power output of the motor of the unmanned aerial vehicle is remarkably reduced, energy is hardly consumed during hovering, the electric energy consumption of flight of the unmanned aerial vehicle is reduced, and meanwhile, the endurance time is multiplied.
