2、 Tile-shaped aerospike nozzle and bell nozzle were studied by experiments and numerical simulation.

4、By employing the gaseous oxygen as oxidizer and gaseous hydrogen as fuel, hot-firing tests were performed for aerospike nozzle and dual-bell nozzle test engines with altitude compensating features.

3、When numbers of the inner nozzle are enough, plug nozzle has less size, less weight and higher thrust efficiency than the bell nozzle under same area ratio.

1、The dual-bell nozzle has an inflection point (12) between the first stage nozzle and the second stage nozzle.
