Beeswax–EVA/Activated-Charcoal-Based Fuels for Hybrid Rockets: Thermal and Ballistic Evaluation
نویسندگان
چکیده
Beeswax (C46H92O) is a naturally derived substance that has the potential to be used as solid fuel for hybrid rocket applications and substitute paraffin wax in rockets. BW burns more efficiently than because of oxygen molecule it contains. The low thermal stability poor mechanical properties limit its practical use upper-stage propulsion applications, these issues are rarely addressed literature on This study investigates ballistic using ethylene-vinyl acetate (EVA) activated charcoal (AC) an additive. BW–EVA/AC compositions was analyzed thermogravimetric analyzer (TGA). blended improved significantly. A laboratory-scale motor evaluate such aspects performance regression rate, characteristic velocity, combustion efficiency. results revealed pure exhibited higher rate 26.5% at oxidizer mass flux 96.4 kg/m2-s compared blends. addition EVA AC found increase experimental velocity efficiency BW-based from 62% 94% when 20 wt.% 2 were added into matrix.

Ballistic Deployment of WSN Nodes using Model Rockets
Wireless sensor networks consisting of a large number of relatively inexpensive nodes are used in a variety of tasks. When being used in difficult to access terrain, or dangerous surroundings, such as often encountered in disaster scenarios, the deployment of a WSN becomes a challenge. In this paper we introduce a novel approach for deploying a WSN: We propose using small-scale model rockets as...
متن کاملMaximizing phonon thermal conductance for ballistic membranes
At low temperatures, phonon scattering can become so weak that phonon transport becomes ballistic. We calculate the ballistic phonon conductance G for membranes using elasticity theory, considering the transition from three to two dimensions. We discuss the temperature and thickness dependence and especially concentrate on the issue of material parameters. For all membrane thicknesses, the best...
