INVESTIGATION OF THE VARIOUS TAPER ANGLE OF THE TIP AND ANGLE OF THE CONICAL SHAPE OF AN AEROSPIKE NOZZLE

This study considers the design of aerospike nozzles and the thrust measurement experiments conducted with various designs, taking into account existing research in the literature. Unlike other studies, this experimental study examines the effects of the angle of the conical shape and the taper angle at the tip of the aerospike nozzle on thrust. Thrust measurement experiments were conducted using a cold gas system. All measurement results were compared, revealing that the design parameters for aerospike nozzle efficiency in this study were a conical shape angle of 45° following the main flow passage and a tapering angle of 30° at the tip of the aerospike nozzle. Additionally, it appears that the taper angle and conical angle of the aerospike nozzle are interrelated in thrust production.
