| description | The invention discloses a similarly axisymmetric inclined outlet convergent-divergent spray pipe and a design method thereof, belongs to the field of aircrafts, and aims to provide the similarly axisymmetric inclined outlet convergent-divergent spray pipe and the design method thereof. According to the technical scheme, the spray pipe through which airflow passes with the flow characteristic of the axisymmetric spray pipe is included, and an air outlet of the spray pipe is obliquely arranged; and the design method comprises the following steps: calculating to obtain an initial flow field basedon a characteristic line method, and obtaining an original axisymmetric spray pipe profile; making a throat section circle (simply referred to as a target circle) of a target spray pipe tangent to the inside in a plane where the throat section of the original spray pipe is located, and establishing a corresponding relationship between the target circle and the throat section of the original spraypipe; and carrying out st |
