This invention proposes a hydrogen fuel turbine engine, including an air intake, a compressor, a hydrogen combustion chamber, a turbine, an exhaust nozzle, and a hydrogen storage device. The hydrogen combustion chamber is supplied with hydrogen via a hydrogen supply pipe, which is installed in an air supply pipe to form an air supply unit. The hydrogen storage device is connected to the hydrogen supply pipe. The air compressed by the compressor enters the hydrogen combustion chamber and is split into two paths. One path directly enters the interior of the flame tube through air holes on the flame tube wall, while the other path is split into multiple paths and connected to the air pipe. The air supply unit enters from the rear end of the flame tube and extends to the front of the flame tube. The hydrogen supply pipe and the air pipe respectively spray hydrogen and air towards the head of the flame tube, where air and hydrogen are mixed and combusted at constant pressure in the flame tube. This invention incorporates an air pipe outside the hydrogen supply pipe. On one hand, this introduces more gas, which lowers the temperature of the main combustion zone in the combustion chamber and reduces the generation of nitrogen oxides. On the other hand, the air pipe can also serve as a heat insulation pipe, effectively reducing the surface temperature of the hydrogen supply pipe. Simultaneously, the air inside the pipe impacts the flame tube head, which not only lowers the temperature of the head panel but also generates a complex vortex structure at the flame tube head, further enhancing the mixing of hydrogen and air. The inconsistent natural frequencies of the vortices prevent thermal oscillation problems.
