rocket enginesAn axisymmetric nonisobaric supersonic jet mixing with the atmosphere or expanding into a vacuum is considered as a model of a rocket engine plume. The expanding caused by the nonisobarity, turbulent mixing and afterburning are main processes forming a plume structure at different ...
The moment where F total becomes zero, the rocket’s acceleration becomes zero, too (a = F/m). After that, negative accelerating forces will decrease the rocket’s velocity, until v=0. That’s the point of equilibrium, the millisecond the rocket stands still in the air. After that it ...
