The invention provides an aircraft fuel tank explosion-proof system and an aircraft, in the system, a gas release lock mechanism is installed at a bottle opening of an inerting gas bottle, the gas release lock mechanism is provided with three outlets which are respectively connected with a filter, a gas outlet and a three-way one-way valve, and a pipeline warmer is arranged on a pipeline between the gas release lock mechanism and the filter; the filter is connected to an inlet of the pressure reducer, and the pressure reducer is mounted in the pressure reducer heating box; the pressure reducer is provided with two outlets, one outlet is connected with an inlet of the small-flow electromagnetic valve through a guide pipe via the flow-limiting warmer, and the other outlet is connected with an inlet of the large-flow electromagnetic valve through a guide pipe. An outlet of the small-flow electromagnetic valve is connected with one sedimentation tank, the one-way valve and the nozzle through pipelines; and an outlet of the large-flow electromagnetic valve is connected with the other sedimentation tank, the one-way valve and the floater valve through pipelines. High-pressure air does not need to be introduced from the engine and the outside, so that the engine power and the use of an environment control system are not influenced; the system is simple in structure, light in weight and low in use cost.
