Meshchersky equation
Webcompliant with a local solution of the known Meshchersky equation according to which for a variable-mass body the expelled mass is equal to the added mass. In a pulsating gas jet, the outside force in relation to the engine will be the force of the gas cyclic mass elastic interaction (Fig. 3) that arises at a definite combination of The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity can thereby move due to the conservation of … Meer weergeven The equation is named after Russian scientist Konstantin Tsiolkovsky who independently derived it and published it in his 1903 work. The equation had been derived earlier by the Meer weergeven Most popular derivation Consider the following system: In the following derivation, "the rocket" is taken to mean "the rocket and all of its unexpended propellant". Newton's second law of motion relates external … Meer weergeven The rocket equation captures the essentials of rocket flight physics in a single short equation. It also holds true for rocket-like … Meer weergeven When viewed as a variable-mass system, a rocket cannot be directly analyzed with Newton's second law of motion because the law is valid for constant-mass systems only. It can … Meer weergeven In order to understand the principle of rocket propulsion, Konstantin Tsiolkovsky proposed the famous experiment "of the boat".

We assume that the velocity of the evaporated atoms v is nearly constant in time and depends only on the surface temperature, so the Meshchersky equation can be used for the recoil force: (2) F = v m ˙ = v ℓ Λ 2 J.
Webequation (1) shows that the increase in the speed of the rocket is possible only by accelerating the jet (for which there are many methods), while not increasing the mass of its propellant.
