    A Pulsed Plasma Thruster (PPT) is the simplest form of electric propulsion that uses the natural properties of plasma to produce thrust and high velocities with low fuel consumption. Compared to other forms of electric propulsion a PPT usually operates by creating a pulsed, high current discharge across the exposed surface of a solid insulator…

    A monopropellant thruster is a thruster that uses a single chemical as its propellant. Monopropellants are propellants that consist of chemicals that release energy through exothermic chemical decomposition. This release of energy is usually accomplished with the help of a catalyst. A monopropellant does not require a separate oxidizer. Also Read: What is a Bipropellant…

    Electrothermal thrusters uses electric energy to heat the propellants either into a plasma or hot gas which is then expanded through a nozzle to produce thrust. Compared to both electromagnetic and electrostatic propulsion systems that propel charged ions through the use of electric and magnetic fields, electrothermal thruster relies upon thermal dynamics to propel the…

    A bipropellant thruster is a thruster that uses two propellants (very often liquid propellants) which are kept separately before reacting to form a hot gas to be used for propulsion. Also Read: What is a Power Processing Unit (PPU) for Thrusters? Bipropellant systems require the combustion of two (Bi) propellants. First one is a fuel and the…

    A cold gas thruster is a type of propulsion system which uses the expansion of pressurized gas to generate thrust. It consist of a fuel tank, a regulating valve, and a propelling nozzle. The nozzle of a cold gas thruster is generally made of a convergent-divergent shape so that it provides a required thrust in…

    An Ion Thruster is a form of electric propulsion that works on the concept of ionization. This process involves the extraction of ions from the plasma to produce thrust. The ions extracted are accelerated by using electric fields that generate many ion jets together called the ion beam that produces the required thrust for the…
