The microwave discharged ion engine, developed for Hayabusa and upgraded for Hayabusa2, worked perfectly, and low- and continuous-thrust trajectory control combined with an Earth gravity assist was successfully applied to the mission. The optical guidance and navigation for approaching, descending, and...
A spacecraft and its launch vehicle are projected upward by the unbalanced pressure inside the rocket engine. There is high pressure on the closed front end of the rocket’s thrust chamber but much lower pressure on the open back end, where the exhaust gases flow out the chamber’s nozzle....
Upgrades derived from the flight test will debut on the next Starship and Super Heavy vehicles to launch from Starbase on Flight 3. SpaceX is also implementing planned performance upgrades, including the debut of a new electronic Thrust Vector Control system for Starship’s upper stage Raptor engi...
thrust vector controllocal controlglobal controlThis paper presents control strategies and simulations of a two-DOF precision platform as an adaptive thruster mount structure with precision positioning and active vibration suppression capabilities for thrust vector control of space satellites. First, the ...

Space storable, thrust-vectorable rocket motor nozzle and related methodsA thrust-vectoring rocket motor nozzle includes a forward assembly having a forward shell with a flange configured for connection to a motor and a throat portion opposite the flange. A ball joint sleeve may be disposed ...
So if you want to beam a message to a precise point in space, rather than merely in a specified direction, each antenna would be aimed along a slightly different vector. In other words, the computer pointing must allow for parallax of the target. So I took the next step. I asked if ...
that produce their revenue stream. A spacecraft docking with the International Space Station needs to keep its docking port aligned with the counterpart on the station. A lunar lander must align its thruster with the desired thrust vector while making sure that its sensors are oriented to receive...
Modeling a Thrust Vector Controlled Rocket in Simulink Thrust Vectoring or Thrust Vector control is the ability of an aircraft or a rocket's propulsion system to manipulate the direction of its thrust to control the rocket or aircrafts attitude or angular velocity. Adjusting the gimbal angle, contr...
A kind of robust control of electromechanical actuator (EMA) system for thrust vector control in a spacecraft was investigated. In the flight of a spacecraft, the EMA system must overcome the influence of load disturbance and working point alteration to improve the robust control performances. Add...
