Multidimensional Unstructured-Grid Liquid Rocket Engine Nozzle Performance and Heat Transfer Analysis [PDF]

40th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2004
The objectives of this study are to conduct a unified computational analysis for computing the design parameters such as axial thrust, convective and radiative wall heat fluxes for liquid rocket engine nozzles, so as to develop a computational strategy for computing those design parameters through parametric investigations.

Factors Influencing Step Ablation in the Expansion Section of a Composite Nozzle in a Solid Rocket Motor

Aerospace
During the operation of a solid rocket motor, the nozzle, which is a key component, is subjected to extreme conditions, including high temperatures, high-speed gas flow, and discrete-phase particles. For composite nozzles incorporating a carbon/carbon (C/

Improved stability analysis of rocket engine nozzles

, 2007
This master’s thesis was conducted at Volvo Aero Corporation (VAC) in Trollhättan at the department of combustion chambers and nozzles. This department is responsible for the development of the main engine nozzle extension to the European Ariane 5 rocket. During space flight there are a variety of loads which may cause structural instability

Design of Rocket Engine Nozzle Using Method of Characteristics

International Journal for Research in Applied Science and Engineering Technology
Abstract: This report focuses on the design of a 2D theoretical layout of a rocket engine nozzle. Convergent and divergent are to be designed separately with the focus on divergent part for a minimum length nozzle. The divergent part is to be designed using method of characteristics with left and right running characteristics using the known (sonic ...
