Human spaceflight, space tourism, and the launch of microsatellites are all expected to grow in future. In fact, with recent increase satellite market, almost 1000 smallsats per year foreseen be launched over next decade. Hybrid rocket propulsion has received significant attention for military commercial applications due its potential safety, throttleable, restart ability when compared solid ro...

RAM- and SCRAM-Jet engines can not generate static thrust only work at high speeds. This starting velocity of the motor v0 is usually generated by carrier rockets or boosters, which mostly use solid propellants based on ammonium perchlorate (AP) hydroxyl-terminated polybutadiene (HTPB). Modern dinitramide (ADN) Glycidyl Azide Polymer (GAP) have significant advantages in terms environmental comp...

As the research on hybrid rocket motors advances, more accurate tools are needed to estimate performance of system by determining its fundamental parameters. One them is certainly regression rate solid fuel. Unfortunately, it depends many complex physical phenomena and interactions which vary with time, space scale, making task predicting evolution very difficult. To address this issue, Computa...

This study investigated reconstruction techniques for building the instantaneous fuel regression rate of hybrid rocket motor (HRM). Specifically, an experiment in a laboratory 500 N-class with single-port wagon wheel grain, operated hydrogen peroxide (HP) and hydroxyl-terminated polybutadiene (HTPB) based (including Al), was carried out. A piece post-processing software developed to reconstruct...

In order to improve nano-aluminized solid propellant properties and performance, different materials are being investigated for coating nano-aluminum particles. Two of the powders which considered V-ALEX, a fluoropolymer (Viton) coated nano-aluminum, L-ALEX, stearic acid nano-aluminum. It is believed that thin layer should protect aluminum core from premature oxidation, as well provide an exoth...
