A Miniaturized Green End-Burning Hybrid Propulsion System for CubeSats
Conventional hybrid rocket motors with thrust levels greater than 5 N rely on forced convection within the boundary layer as the primary heat-transfer mechanism for fuel vaporization. For hybrid
Fuel regression behavior of swirling-injection end-burning hybrid rocket engine
Typical hybrid rockets, using solid plastic fuel and liquid oxidizer, have the potential to become non-explosive propulsion systems based on boundary layer combustion (Takahashi and Shimada, 2018).
Experimental Study and a Short Kinetic Model for High-Temperature Oxidation of Methyl Methacrylate
ABSTRACT Synthetic and natural polymeric esters find applications in transport and construction sectors, where fire safety is an important concern. One polymer that is widely used is poly (methyl
Investigation of Dual-Vortical-Flow Hybrid Rocket Engine without Flame Holding Mechanism
A 250 kgf thrust hybrid rocket engine was designed, tested, and verified in this work. Due to the injection and flow pattern of this engine, this engine was named dual-vortical-flow engine. This
Hybrid propulsion system for CubeSat applications
The CubeSats platform has become a common basis for the development and flight of very small, low cost spacecraft-particularly amongst University groups. The smallest CubeSats are just 1 litre in
Development and Three-dimensional Numerical Simulation of a Double-tube Hybrid Rocket Motor
This paper presents a new concept of Hybrid Rocket Motor (HRM) called Double-tube. In this configuration, the gaseous oxidizer is injected using a head end injector and an inner tube with injector
Characterisation of multiple concentric vortices in hybrid rocket combustion chambers
