The invention discloses a trailing edge blowing type stabilizer structure suitable for incoming flow distortion. The trailing edge blowing type stabilizer structure is mainly composed of an annular stabilizer and a radial V-shaped groove standby stabilizer. During operation, head-on incoming flow is sucked into a mixing chamber through a stabilizer suction slit, spray atomized fuel oil is furthersheared and atomized at the edge of a baffle, the fuel oil evaporates in the mixing chamber and is blended with gas stream, most oil and gas mixture is further atomized and blown out with the trailingedge to be mixed with the incoming flow for combustion and to be rolled into a recirculation zone, a small amount of oil and gas mixture blown out from the suction slit of the baffle enhances combustion in the recirculation zone, flame stability under the incoming flow distortion condition can be achieved, the length of a mixing zone before the combustion chamber is effectively shortened, the difficulty of the high combus
