AbstractThis article evaluates the wave velocity of a leptadenia pyrotechnica rheological elastomer (LPRE) microbeam surrounded by micro piezoelectric and porosity of functionally graded materials' (FGMs) layers. Different models of graphene nano plates (GPLs) for reinforcing the face sheet are assumed by adopting Halpin–Tsai modified micromechanics ...

Near-field Film Thickness Measurements of an LPRE Swirl Injector Spray
47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011A novel approach to the measure of liquid film thickness in the near-field of a liquid rocket swirl injector spray was developed. Archived data were analyzed, wherein liquid mass flow was throttled over a range of 0.064 to 0.082 kg/s—corresponding to injection pressure drops of 0.80 to 1.26 MPa.

Thrust and propellant mixture ratio control of open type LPRE using Q-ILC
2007 International Conference on Control, Automation and Systems, 2007LPRE(Liquid Propellant Rocket Engine) is one of the important parts to control the motion of rocket. For operation of rocket in error boundary of the set-up trajectory, it is necessary to control the thrust of LPRE according to the required thrust profile and control the mixture ratio of propellants fed into combustor for the constant mixture ratio. It

New Concepts in Structural Analysis and Design of Double Walled LPRE Thrust Chambers
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006thermal ratchetting. Details of exhaustive material characterization done for the thrust chamber materials are highlighted. Cyclic life prediction of the inner wall is done using the cumulative damage accumulation technique. Allowable number of hot runs for the chamber is arrived at after employing suitable factor of safety for these individual damage ...

DEVELOPMENT OF A DIFFERENTIAL MODEL FOR COOLING AN LPRE CHAMBER BY AN INCOMPRESSIBLE FLUID
Vìsnik Dnìpropetrovsʹkogo Unìversitetu Serìâ: Raketno-kosmìčna TehnìkaAbstract. The combustion chamber constitutes a crucial component of a liquid rocket engine (LPRE), and approximately 30% of serial engine failures are attributed to issues within it. Primarily, challenges encountered during engine chamber operation stem from the inadequacy of the current cooling systems to manage thermal loads effectively. These loads,
