摘　　要：为了了解塞式喷管性能 ,采用固体推进剂对塞式喷管单元发动机进行了模拟实验。重点介绍了塞式喷管单元发动机模拟实验的实验系统和高精度测量系统以及数据采集软件。同时 ,简单说明了数据处理的方法。最后给出了典型的实验结果 ,该结果对塞式喷管的设计。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.
