| Abstract: |
| In order to study fluctuating pressure characteristics and laws on the re-entry warhead’s surface, a flight test rocket was designed to obtain fluctuating pressure, average pressure, temperature outside and structural vibration and impact inside of the test section through a free flight, which could help understand and predict the correlation between fluctuating pressure and structural response and provide data to simulate the response of the structure. Under the purpose and requirement of the flight test, the overall parameters and compositions of the rocket were designed and calculated. Several key technologies, such as overall design, test system design, heat shielding, aerodynamic and trajectory design were developed. The re-entry environment flight test rocket was finished, which obtained aerodynamic data, trajectory data and structural response data through flight test successfully. The correction and effectiveness of the flight test rocket’s overall design and key technologies were verification through ground tests. |
