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...
متن کاملDispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion 25 Dispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion
Environmental impact assessment of liquid rocket motor exhaust obtained due to mainly liquid propellant combustion have been highlighted. Exhaust product analysis has been carried out theoretically by computer software NASA CEC -71 to identify toxic emissions of rocket combustion. In the present study a high volume Air Samplers (APM-430) was deployed at predetermined locations near launch pad f...

متن کاملUnsteady Ballistic Code for Performance Prediction of Solid Propellant Rocket Engines
Solid Propellant Rockets (SPRs) by their very nature embody in their chemical properties and geometry the whole history of grain combustion from ignition to burnout. Thus, the development of robust and reliable ballistic codes for accurate prediction of SPR performance is critical for their cost-effective utilization in space propulsion applications, especially in the case of launch vehicle boo...
متن کاملOn the hydrodynamics of rocket propellant engine inducers and turbopumps
The lecture presents an overview of some recent results of the work carried out at Alta on the hydrodynamic design and rotordynamic fluid forces of cavitating turbopumps for liquid propellant feed systems of modern rocket engines. The reduced order models recently developed for preliminary geometric definition and noncavitating performance prediction of tapered-hub axial inducers and centrifuga...
