The main objective is to analyze a rocket engine nozzle to understand the phenomena of various design conditions under different convergent angle, divergent angle and throat radius by Computational Fluid Dynamic (CFD). There have also mentioned about inlet boundary conditions with specification according...
Hybrid Rocket EngineDe Laval NozzlePropellantPropulsionModellingSimulationThe study gives a general overview of the CFD-simulated gas flow via the nozzle of a De Laval rocket engine. In CFD software, the mesh is generated using the nozzle's geometry. In this work, CFD methods are used to ...
Performance Analysis Model of Rocket Ejector Mode was established,based on quasi-1D transient flow equations.Factors such as skin friction,finite rate chemical reaction and mass injection were taken into account.A MacCormack scheme was adopted for solving the equations,which obtains by-pass ratio corr...
A Coupled Field Fluid Flow And Structural Analysis Of A Nozzle Used In A Supersonic Artillery Rocket 来自 ResearchGate 喜欢 0 阅读量: 14 作者: M Nandgaonkar 摘要: Thermal Power Stations all over the world are facing the problem of boiler tube leakage frequently. The consequences of which ...
The launcher is comprised of two concentric cylinders joined at the aft end with a hemisphere (Fig. 1). The missile is launched and initially guided from the inner cylinder. After ejection from the motor nozzle, rocket gases (arrows in Fig. 1) strike the hemisphere and are turned 180°. ...
The extending displacement,velocity and acceleration and internal pressure of the actuator of a solid rocket motor(SRM) extendible exit cone(EEC) nozzle were calculated.Firstly,the nozzle was reduced to a one degree-of-freedom dynamic system,and then the dynamic equations describing the extending pro...
Performance of Solid Propellant Rocket Motors with Variation in Nozzle Geometry The nozzle geometry affects the performance achieved by a solid propellant rocket motor to a great extent. In order to improve the development of a small home made solid propellant rocket motor these effects on performance...
52 The cracks in hydraulic pipeline system was located at the root of flat nozzle, and it was the 12 mm away from the pipe fitting, as shown in Fig. 11.52 The causes of the faults were found by the vibration simulation analysis of hydraulic pipeline system, and the preventive and ...
To provide a reference for the design of reusable thrust chambers, and further promote the practical use of LOX/Methane engines, the thermal and structural responses of the regeneratively-cooled thrust chamber wall of LOX/Methane rocket engine under cyclic work are obtained by a numerical methodolog...
In the 1960s, the concept of the orbital refilling depot was proposed, and the refueling of spacecraft in-orbit has been regarded as a fundamental solution to break through the limitations of carrying capacity and exploration scope [1]. The use of orbital refueling technology could also make ...
