Thermal–Mechanical FEM Analyses of a Liquid Rocket Engines Thrust Chamber

A Magnetic Thrust Chamber Design For A Laser Fusion Rocket Based on Impact Fast Ignition Scheme

The laser fusion rocket, which is expected as a rocket that it replaces one of the chemical propulsions, can be efficiently operated by using a shaped target. The shaped target is made of fusion pellet and the pellet is surrounded by a moderator (propellant). We here examine the applicability of the impact fast ignition scheme to the shaped target. It was found that it is difficult to increase ...

Modeling of Heat Losses Within Combustion Chamber of Diesel Engines

The cylinder working fluid mean temperature, rate of heat fluxes to combustion chamber and temperature distribution on combustion chamber surface will be calculated in this research. By simulating thermodynamic cycle of engine, temperature distribution of combustion chamber will be calculated by the Crank-Nicolson method. An implicit finite difference method was used in this code. Special treat...

Substructure Method for Thermal-Stress Analysis of Liquid-Propellant Rocket Engine Combustion Chamber

This article is devoted to an important problem of calculation of deflected mode of the combustion chamber and the nozzle end of a new liquid-propellant rocket cruise engine. A special attention is given to the methodology of calculation. Three operating modes are considered. The analysis has been conducted in ANSYS software. The methods of conducted research are mathematical modeling, substruc...

Hybrid-Knowledge-Models-Based Intelligent Fault Diagnosis Strategies for Liquid-propellant Rocket Engines

This paper focuses on a qualitative fault diagnosis method based on the integration and fusion of shallow and deep knowledge for liquid-propellant rocket engines (LRE). The paper firstly clarifies the concept and the types of LRE diagnosis knowledge. Later, from the isomorphic transform point of view, the paper analyses the correlation of different knowledge and knowledge representation, and fo...
