The current project aims at the understanding of the propulsive parameters of hybrid rocket motors. Computational simulations using the software CEA-NASA were carried out. The fuels paraffin wax, hydroxyl-terminated polybutadiene (HTPB) and polymethyl methacrylate (PMMA) were combined with three oxidizers: liquid oxygen (LOX), nitrous oxide (N2O) and ...

Propellants based on HTPB/AP (hydroxyl-terminated polybutadiene/ammonium perchlorate) are the most commonly used in most of the rocket engines used by the Brazilian Armed Forces. This work aimed at the possibility of extending its useful life (currently in 10 years) by performing chemical kinetic analysis of the energetic material via differential ...

THE USEGE OF GAS-DYNAMIC PIPES IN FIRE TEST BENCHES OF LOW-THRUST LIQUID ROCKET ENGINES
System design and analysis of aerospace technique characteristicsThis scientific article examines the process of designing a gas dynamic tube used for testing liquid rocket engines on firing stands with simulated vacuum conditions. The gas dynamic tube is an integral component of the extensive testing stand system as it facilitates the creation of a rarefied environment during the operation of the rocket engine ...

Strength bench testing of models and structural elements of rocket and space equipment
2019The paper considers the methodological support and evaluation of operation reliability of rocket and space equipment using the inlet lips of ramjet engine (RJE) as an example. The successful solution to these issues is largely defined by the optimal selection of materials - special high-temperature alloys and structural ceramics.The methods for ...
