[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings:
[0031] The method of the present invention includes the following steps:
[0032] Step one, use laser selective melting and additive manufacturing to form an aviation fuel nozzle housing 2 with a closed cavity structure, such as Figure 1-2 As shown, the forming direction of the nozzle housing 2 parts is placed vertically.
[0033] The nozzle housing 2 includes a nozzle head, a rod, and a mounting plate that are connected in sequence. The bottom of the mounting plate is provided with a main oil passage oil inlet interface and a secondary oil passage oil inlet interface, a main oil passage oil inlet interface and a secondary oil passage oil inlet interface. They are perpendicular to each other and are connected to two independent oil passages respectively. The two independent oil passages are arranged inside the rod, the nozzle head is provided with a nozzle opening...
