The Last Empty Sky — the development of the rocket: 1920 to 1957. The episode mentions Konstantin Tsiolkovsky, Hermann Oberth, Robert Goddard, Wernher von Braun, and Sergey Korolyov as the key figures in development of multistage liquid-fueled rockets. The High Ground — the first artificial satellite and the first humans in space.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. 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 and can thereby move due to the ...
In November 2023, the six-episode series Connections with James Burke, premièred on Curiosity Stream, again with Burke as the on-screen presenter. [1] In 2004, KCSM-TV produced a program called Re-Connections, consisting of an interview of Burke and highlights of the original series, for the 25th anniversary of the first broadcast in the US on ...
The Tsiolkovsky rocket equation, or ideal rocket equation, can be useful for analysis of maneuvers by vehicles using rocket propulsion. [2] A rocket applies acceleration to itself (a thrust) by expelling part of its mass at high speed. The rocket itself moves due to the conservation of momentum.
The definition arises naturally from Tsiolkovsky's rocket equation: = where Δv is the desired change in the rocket's velocity; v e is the effective exhaust velocity (see specific impulse) m 0 is the initial mass (rocket plus contents plus propellant)
Tsiolkovsky was born in Izhevskoye [] (now in Spassky District, Ryazan Oblast), in the Russian Empire, to a middle-class family.His father, Makary Edward Erazm Ciołkowski, was a Polish forester of Roman Catholic faith who relocated to Russia; [6] his Russian Orthodox mother Maria Ivanovna Yumasheva was of mixed Volga Tatar and Russian origin.
The Tsiolkovsky rocket equation—the principle that governs rocket propulsion—is named in his honor (although it had been discovered previously, Tsiolkovsky is honored as being the first to apply it to the question of whether rockets could achieve speeds necessary for space travel). [70]
The specific impulse of a rocket can be defined in terms of thrust per unit mass flow of propellant. This is an equally valid (and in some ways somewhat simpler) way of defining the effectiveness of a rocket propellant. For a rocket, the specific impulse defined in this way is simply the effective exhaust velocity relative to the rocket, v e ...
