The Juno spacecraft includes 12 Aerojet Rocketdyne MR-111C 1.0 lbf
monopropellant hydrazine Rocket Engine Assemblies that have provided attitude control for the spacecraft throughout its journey, as well as during insertion into Jupiter's orbit, which occurred on July 4, 2016.
Zhang, "A model for the operation of nitrous oxide
monopropellant," Aerospace Science and Technology, vol.
This recent technological achievement involved running the patented Cyclone Engine by the combustion of an environmentally friendly
monopropellant called Moden Fuel.
The major objective of the contract is to design a
monopropellant propulsion system, which is a mission critical subsystem of the satellite Guidance and Navigation Control System.
up to 1 to 2 tons depending on the payload) are generally based on
monopropellant systems in a blow down configuration given the low Delta-V needed.
"A year ago it was a hybrid rocket, but now for the first record attempt we will use only the
monopropellant part of the rocket.
Once separated from the launch vehicle, the GPM satellite uses 12 Aerojet Rocketdyne MR-106L 5.0 lbf
monopropellant thrusters for attitude control.
Early in 2009 the project decided that the early runs of the car would be conducted with a
monopropellant chamber.
Twelve Aerojet Rocketdyne
monopropellant (hydrazine) thrusters in four modules on the Delta IV upper stage provided roll, pitch and yaw control as well as settling burns for the upper stage main engine.
Running excess HTP through the system has been successfully used to extinguish the flame in earlier tests of the
monopropellant rocket, too, and was the plan for the Newquay firing.
Aerojet Rocketdyne's role in the launch primarily began with the second stage, when a single RL10A-4-2 engine ignited to place the TDRS-L into orbit, helped by the 12 Aerojet Rocketdyne
monopropellant (hydrazine) thrusters in four modules on the Atlas V Centaur upper stage providing roll, pitch and yaw control as well as propellant settling burns during ascent.
H2o2 can be used as
monopropellant or as oxidizer with green fuel (like ethanol or bio diesel) in bipropellant thrusters.
