An aerospace fuel spray device

Abstract

This utility model relates to the technical field of fuel spray devices, and discloses an aerospace fuel spray device, including a fuel spray head, which has an inner cavity, a spray chamber, a diffusion groove, and a fuel delivery hole. Fuel is delivered to the inner cavity through the fuel delivery hole, and then delivered to the spray chamber by air jet within the inner cavity, where it is diffused by fuel spray at the diffusion groove. The sidewall of the diffusion groove has multiple mounting grooves. In this utility model, when fuel is sprayed outward in the spray chamber with high-speed airflow, several fan plates on several mounting rings can be blown and rotated around the mounting shaft. When the fuel spray is blown onto the fan plates with high-speed airflow, the fuel spray can further pass through multiple plate holes on the fan plates by the rotation and beating of the fan plates on the mounting rings, thereby achieving further atomization of the fuel spray. The further refined fuel spray has a large contact area with the air, which can quickly and completely burn.
