This invention relates to the field of aero-engine technology, disclosing a combustion assembly and an aero-engine. The invention includes: a flame tube; an evaporator tube comprising a main pipe and several branch pipes, one end of the main pipe forming an evaporator tube inlet, the branch pipes corresponding to the other end of the main pipe, and the ends of the branch pipes away from the main pipe forming several evaporator tube outlets, which are located within the flame tube; and a fuel supply structure connected to the evaporator tube inlet. This invention, by arranging the branched evaporator tubes in a blood vessel-like pattern on the flame tube, increases the probability of fuel breaking up upon impact with the wall under the action of the branched structure, resulting in better fuel atomization. Simultaneously, because the branched evaporator tubes have a larger contact area with the hot wall surface, they absorb more heat, thus allowing the fuel to be heated more fully, thereby evaporating more fuel and ultimately improving combustion efficiency.
