Design and optimization of variable thrust hybrid rocket motors for sounding rockets
Science China Technological Sciences, 2011Besides safety and low-cost, the start/shutdown/restarting and throttling ability are the other two significant advantages of hybrid rocket motors (HRMs) compared with liquid and solid ones. In this study, a two-stage variable thrust and non-toxic 98%HP/HTPB hybrid rocket motor (VTHRM) is designed and applied in a sounding rocket, and the design ...

Vortex combustion in a hybrid rocket motor
, 2016 The work is focused on a vortex flow pancake hybrid rocket motor (VFP). This hybrid rocket configuration is characterized by two flat solid fuel disks and a tangential injection between them. The gap between the two flat disks serves as combustion chamber.

Hybrid rocket motor fuel studies
33rd Joint Propulsion Conference and Exhibit, 1997Results from four fuel characterization studies are reported. The first study was a premix (complete fuel except for curative) hold time determination which concluded that a full-scale 600-gal premix could be held for at least 3 weeks without any harmful degradation of the cured final fuel.

Optimal Design of Hybrid Rocket Motors for Microgravity Platform
Journal of Propulsion and Power, 2008A nested direct/indirect method is used to find the optimal design for a microgravity platform which is based on a hybrid sounding rocket. The direct optimization of the parameters that affect the motor design is coupled with the indirect trajectory optimization to maximize a given mission performance index.
