A cold gas thruster (or a cold gas propulsion system) is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust.As opposed to traditional rocket engines, a cold gas thruster does not house any combustion and therefore has lower thrust and efficiency compared to conventional monopropellant and bipropellant rocket engines.
Some devices that are used or proposed for use as thrusters are: Cold gas thruster; Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere) Electrodeless plasma thruster, electric propulsion using ponderomotive force; Electrostatic ion thruster, using high-voltage electrodes; Hall effect thruster, a type of ion thruster
Nitrous oxide fuel blend propellants are a class of liquid rocket propellants that were intended in the early 2010s to be able to replace hydrazine as the standard storable rocket propellent in some applications.
It carries ThrustMe's I2T5 non-pressurized cold gas thruster, the first in existence. [16] BeiHangKongshi-1 is a 12-unit cubesat developed by Spacety. The satellite carries ThrustMe's NPT30-I2-1U, the first iodine electric propulsion system sent into space. [3] The cubesat was launched on board the Long March 6 on 6 November 2020. [17]

The simplest case of a thermal rocket is the case in which a compressed gas is held in a tank, and is released through a nozzle. This is known as a cold gas thruster.The thermal source, in this case, is simply the energy contained in the heat capacity of the gas.
RL-10 is an early example of cryogenic rocket engine.. Rocket engines need high mass flow rates of both oxidizer and fuel to generate useful thrust. Oxygen, the simplest and most common oxidizer, is in the gas phase at standard temperature and pressure, as is hydrogen, the simplest fuel.
The Rochester Institute of Technology was building an HTPB hybrid rocket to launch small payloads into space and to several near-Earth objects. Its first launch was in the Summer of 2007. Scaled Composites SpaceShipOne , the first private crewed spacecraft, was powered by a hybrid rocket burning HTPB with nitrous oxide: RocketMotorOne .
