| Abstract: |
| Objective To fulfill the thermal protection requirements on high trajectory flight of long range rocket projectile without coating and propose a design thought on increasing the shell thickness. Methods A trajectory coupled aerodynamic heating compute was adopted to analyze temperature changes of bullet wall surface of various materials and different thickness. Results When the shell thickness was above 20mm, temperature on external surfaces of shell made of aluminum, steel and copper was below 150 ℃. In shells of the same thickness, steel shell has the best cooling capability. Conclusion Increasing the shell thickness can reduce the wall temperature effectively. |
