The invention relates to the technical field of aero-engine nozzles and air exhausting, and particularly provides a binary vector nozzle capable of achieving pressure self balance of an expansion section and an aero-engine with the same. According to the binary vector nozzle, a pressure adjusting sheet for pressure controlling is installed at the expansion section, and the purposes of antivibration and vibration reduction on a nozzle component are achieved by balancing the internal and external pressure difference of the wall surface of the nozzle through the pressure adjusting sheet; meanwhile, external airflow flowing through the pressure adjusting sheet further has the effect of reducing the nozzle wall temperature; and compared with a traditional vector nozzle, the binary vector nozzlecan realize self balance of the internal and external pressure of the wall surface of the nozzle without an additional driving mechanism, and the safety and reliability of the binary vector nozzle are remarkably improved.
