The present invention discloses a flexible exhaust passage with a dynamic balance system, and belongs to the technical field of unmanned aerial vehicles. The flexible exhaust passage with the dynamic balance system comprises: an exhaust pipe, wherein the exhaust pipe is installed on a vehicle body and flexibly connected with an engine in the vehicle body; an exhaust end, wherein the exhaust end is disposed at an end portion of the exhaust pipe and comprises a tapered cylinder and an anechoic chamber, the tapered cylinder comprises a tapered wide opening and a tapered narrow opening, a side wall of the tapered cylinder is provided with a plurality of circulation ports, the anechoic chamber sleeves the periphery portion of the tapered cylinder, and an exhaust port is disposed in the anechoic chamber; thermal shields, wherein the thermal shields are respectively disposed at periphery portions of the engine and the exhaust pipe; a cooling system, wherein the cooling system is fixed on the vehicle body; and the dynamic balance system, wherein the dynamic balance system is rotatably fixed at the tail portion. According to the flexible exhaust passage, the technical defect that in the prior art, noise pollution caused by large noises when the exhaust pipe exhausts tail gas without an independent noise-abatement device or noise-abatement structure is solved.
