The present invention takes advantage of winding fiber yarn outer layer to keep the radius of the throat of the 3D braided inner layer to meet design requirement. Additionally, the hoop strength of the throat section is increased so that the metal shell can be made thinner to reduce the weight of the rocket nozzle. | | 聯絡人姓名 | 黃茂益 |
