Hybrid Rockets with Axial Injector: Port Diameter Effect on Fuel Regression Rate
TL;DR: In this article, a numerical reconstruction of a series of test data obtained with static firings of a lab-scale hybrid rocket is carried out with a Reynolds-averaged Navier-Stokes solver including detailed gas-surface interaction modeling based on surface mass and energy balances.
Journal ArticleDOI
Numerical investigation on the regression rate of hybrid rocket motor with star swirl fuel grain
Shuai Zhang,Fan Hu,Weihua Zhang +2 more
TL;DR: In this article, an attempt has been made to numerically investigate the flow field characteristics and local regression rate distribution inside the hybrid rocket motor with complex star swirl grain, where a propellant combination with GOX and HTPB has been chosen.

Francesco Battista,Daniele Cardillo,Manrico Fragiacomo,Giuseppe D. Di Martino,Stefano Mungiguerra,Raffaele Savino +5 more
TL;DR: In this article, a 1000 N class breadboard, fed with gaseous oxygen coupled with a paraffin-based fuel grain, was designed and experimentally tested in different conditions.
Journal ArticleDOI
Effect of Varying Design Options on the Transient Behavior of a Hybrid Rocket Motor
TL;DR: In this article, a set of design options of a hybrid rocket motor is evaluated for propulsion of micro air launch vehicles, and a simulation code is based on a legacy interior ballistic model.
Proceedings ArticleDOI
Interaction of vortices due to diaphragm on the wall blowing surface
TL;DR: In this article, the role of diaphragm on the downstream flow dynamics was investigated, and it was shown that the installation of a diaphram can introduce the decreasing or increasing trend of fluctuating motion on downstream flow field depending on the axial location.

Turbulent boundary layer combustion in the hybrid rocket
G. Marxman,M. Gilbert +1 more
TL;DR: In this article, it has been shown that the flame height above the surface should be in the range of 10% to 20% of the boundary layer thickness, depending on operating conditions.
Book ChapterDOI
Fundamentals of Hybrid Boundary-Layer Combustion
TL;DR: In this article, a regression rate equation for hybrid motors in which convective heat transfer to the grain is the rate-limiting mechanism is developed for the flat-plate flow and the theoretically predicted flame position and regression rate for a flatplate flow are compared with measurements from a Plexiglas-oxygen slab burner.
Journal ArticleDOI
Solid-Fuel Regression Rate Behavior of Vortex Hybrid Rocket Engines
TL;DR: In this paper, the authors investigate the behavior and properties of a vortex hybrid engine with a cylindrical fuel port, where the oxidizer is injected through a swirl injector located between the aft end of the fuel grain and the inlet to the converging portion of the exit nozzle.
