This component set enables you to equip the spacecraft with one or more thrusters, each with its own orientation, engine model and other characteristics.

The Thruster Sets components are:
The attributes for each Thruster Set component are the same. To set the direction definition, use the "Direction Definition" syntax given in the Syntax section of this help page. There is one attribute for direction definition, defined in the following table.
| Attribute | Values |
|---|---|
| DirectionDefinition | "Acceleration", "Exhaust" |
To define attributes of individual thrusters, use the "Thruster Attributes" syntax given in the Syntax section of this help page. The thruster attributes are defined in the following table.
| Attribute | Values/Description |
|---|---|
| Cartesian.X | <Numerical> |
| Cartesian.Y | <Numerical> |
| Cartesian.Z | <Numerical> |
| Spherical.Azimuth | <Numerical> |
| Spherical.Elevation | <Numerical> |
| EngineModel | <Engine Model compnent> |
| ThrustEfficiency | <Numerical> |
| EquivOnTime | <Numerical> Enter a percentage figure. The equivalent on-time percentage is a factor multiplied by the thrust. The thrust is applied continuously throughout the maneuver and is reduced by the percentage. The mass flow rate is likewise reduced. For example, for an on-time percentage of 75%, the acceleration on the spacecraft will be reduced by 25%, and only 75% of the fuel will be used. |
