| Abstract: |
| To find out the performance characteristic of aerospike nozzle, the simulated tests were a aerospike engine unit using solid propellant. The experimental system and data acquisition system for simulated tests of an aerospike nozzle unit including the software of the data acquisition were presented in detail. The method of data handling was also showed summarized.Typical experimental results, which can be used as a reliable basis for the design and development of advanced aerospike engines and also can be used to validate the theoretical and numerical computation, are also showed. |
