The component of an Engine or RCS part that generates thrust. Can obtained by calling Engine.getThrusters() or RCS.getThrusters().

Note

Engines can consist of multiple thrusters. For example, the S3 KS-25x4 “Mammoth” has four rocket nozzels, and so consists of four thrusters.

Part getPart()¶: The Part that contains this thruster.

org.javatuples.Triplet<Double, Double, Double> thrustPosition(ReferenceFrame referenceFrame)¶

The position at which the thruster generates thrust, in the given reference frame. For gimballed engines, this takes into account the current rotation of the gimbal.

Parameters:

referenceFrame (ReferenceFrame) – The reference frame that the returned position vector is in.

Returns:

The position as a vector.

org.javatuples.Triplet<Double, Double, Double> thrustDirection(ReferenceFrame referenceFrame)¶

The direction of the force generated by the thruster, in the given reference frame. This is opposite to the direction in which the thruster expels propellant. For gimballed engines, this takes into account the current rotation of the gimbal.

Parameters:

referenceFrame (ReferenceFrame) – The reference frame that the returned direction is in.

Returns:

The direction as a unit vector.

ReferenceFrame getThrustReferenceFrame()¶

A reference frame that is fixed relative to the thruster and orientated with its thrust direction (Thruster.thrustDirection(ReferenceFrame)). For gimballed engines, this takes into account the current rotation of the gimbal.

The origin is at the position of thrust for this thruster (Thruster.thrustPosition(ReferenceFrame)).
The axes rotate with the thrust direction. This is the direction in which the thruster expels propellant, including any gimballing.
The y-axis points along the thrust direction.
The x-axis and z-axis are perpendicular to the thrust direction.

boolean getGimballed()¶: Whether the thruster is gimballed.

org.javatuples.Triplet<Double, Double, Double> gimbalPosition(ReferenceFrame referenceFrame)¶

Position around which the gimbal pivots.

Parameters:

referenceFrame (ReferenceFrame) – The reference frame that the returned position vector is in.

Returns:

The position as a vector.

org.javatuples.Triplet<Double, Double, Double> getGimbalAngle()¶: The current gimbal angle in the pitch, roll and yaw axes, in degrees.

org.javatuples.Triplet<Double, Double, Double> initialThrustPosition(ReferenceFrame referenceFrame)¶

The position at which the thruster generates thrust, when the engine is in its initial position (no gimballing), in the given reference frame.

Parameters:

referenceFrame (ReferenceFrame) – The reference frame that the returned position vector is in.

Returns:

The position as a vector.

Note

This position can move when the gimbal rotates. This is because the thrust position and gimbal position are not necessarily the same.

org.javatuples.Triplet<Double, Double, Double> initialThrustDirection(ReferenceFrame referenceFrame)¶

The direction of the force generated by the thruster, when the engine is in its initial position (no gimballing), in the given reference frame. This is opposite to the direction in which the thruster expels propellant.

Parameters:

referenceFrame (ReferenceFrame) – The reference frame that the returned direction is in.

Returns:

The direction as a unit vector.

Trees of Parts ¶

Vessels in KSP are comprised of a number of parts, connected to one another in a tree structure. An example vessel is shown in Figure 1, and the corresponding tree of parts in Figure 2. The craft file for this example can also be downloaded here.

../../../_images/parts.png — **Figure 1** – Example parts making up a vessel.¶

../../../_images/parts-tree.png — **Figure 2** – Tree of parts for the vessel in Figure 1. Arrows point from the parent part to the child part.¶

Traversing the Tree ¶

The tree of parts can be traversed using the attributes Parts.getRoot(), Part.getParent() and Part.getChildren().

The root of the tree is the same as the vessels root part (part number 1 in the example above) and can be obtained by calling Parts.getRoot(). A parts children can be obtained by calling Part.getChildren(). If the part does not have any children, Part.getChildren() returns an empty list. A parts parent can be obtained by calling Part.getParent(). If the part does not have a parent (as is the case for the root part), Part.getParent() returns null.

The following Java example uses these attributes to perform a depth-first traversal over all of the parts in a vessel:

import krpc.client.Connection;
import krpc.client.RPCException;
import krpc.client.services.SpaceCenter;
import krpc.client.services.SpaceCenter.Part;
import krpc.client.services.SpaceCenter.Vessel;

import org.javatuples.Pair;

import java.io.IOException;
import java.util.ArrayDeque;
import java.util.Deque;

public class TreeTraversal {
    public static void main(String[] args) throws IOException, RPCException {
        Connection connection = Connection.newInstance();
        Vessel vessel = SpaceCenter.newInstance(connection).getActiveVessel();
        Part root = vessel.getParts().getRoot();
        Deque<Pair<Part, Integer>> stack = new ArrayDeque<Pair<Part, Integer>>();
        stack.push(new Pair<Part, Integer>(root, 0));
        while (stack.size() > 0) {
            Pair<Part, Integer> item = stack.pop();
            Part part = item.getValue0();
            int depth = item.getValue1();
            String prefix = "";
            for (int i = 0; i < depth; i++) {
                prefix += " ";
            }
            System.out.println(prefix + part.getTitle());
            for (Part child : part.getChildren()) {
                stack.push(new Pair<Part, Integer>(child, depth + 1));
            }
        }
        connection.close();
    }
}

When this code is execute using the craft file for the example vessel pictured above, the following is printed out:

Command Pod Mk1
 TR-18A Stack Decoupler
  FL-T400 Fuel Tank
   LV-909 Liquid Fuel Engine
    TR-18A Stack Decoupler
     FL-T800 Fuel Tank
      LV-909 Liquid Fuel Engine
      TT-70 Radial Decoupler
       FL-T400 Fuel Tank
        TT18-A Launch Stability Enhancer
        FTX-2 External Fuel Duct
        LV-909 Liquid Fuel Engine
        Aerodynamic Nose Cone

        LV-909 Liquid Fuel Engine
        Aerodynamic Nose Cone
   LT-1 Landing Struts
   LT-1 Landing Struts
 Mk16 Parachute

Attachment Modes ¶

Parts can be attached to other parts either radially (on the side of the parent part) or axially (on the end of the parent part, to form a stack).

For example, in the vessel pictured above, the parachute (part 2) is axially connected to its parent (the command pod – part 1), and the landing leg (part 5) is radially connected to its parent (the fuel tank – part 4).

The root part of a vessel (for example the command pod – part 1) does not have a parent part, so does not have an attachment mode. However, the part is consider to be axially attached to nothing.

The following Java example does a depth-first traversal as before, but also prints out the attachment mode used by the part:

import krpc.client.Connection;
import krpc.client.RPCException;
import krpc.client.services.SpaceCenter;
import krpc.client.services.SpaceCenter.Part;
import krpc.client.services.SpaceCenter.Vessel;

import org.javatuples.Pair;

import java.io.IOException;
import java.util.ArrayDeque;
import java.util.Deque;

public class AttachmentModes {
    public static void main(String[] args) throws IOException, RPCException {
        Connection connection = Connection.newInstance();
        Vessel vessel = SpaceCenter.newInstance(connection).getActiveVessel();
        Part root = vessel.getParts().getRoot();
        Deque<Pair<Part, Integer>> stack = new ArrayDeque<Pair<Part, Integer>>();
        stack.push(new Pair<Part, Integer>(root, 0));
        while (stack.size() > 0) {
            Pair<Part, Integer> item = stack.pop();
            Part part = item.getValue0();
            int depth = item.getValue1();
            String prefix = "";
            for (int i = 0; i < depth; i++) {
                prefix += " ";
            }
            String attachMode = part.getAxiallyAttached() ? "axial" : "radial";
            System.out.println(prefix + part.getTitle() + " - " + attachMode);
            for (Part child : part.getChildren()) {
                stack.push(new Pair<Part, Integer>(child, depth + 1));
            }
        }
        connection.close();
    }
}

When this code is execute using the craft file for the example vessel pictured above, the following is printed out:

 TR-18A Stack Decoupler - axial
  FL-T400 Fuel Tank - axial
   LV-909 Liquid Fuel Engine - axial

Fuel Lines ¶

Fuel lines are considered parts, and are included in the parts tree (for example, as pictured in Figure 4). However, the parts tree does not contain information about which parts fuel lines connect to. The parent part of a fuel line is the part from which it will take fuel (as shown in Figure 4) however the part that it will send fuel to is not represented in the parts tree.

Figure 5 shows the fuel lines from the example vessel pictured earlier. Fuel line part 15 (in red) takes fuel from a fuel tank (part 11 – in green) and feeds it into another fuel tank (part 9 – in blue). The fuel line is therefore a child of part 11, but its connection to part 9 is not represented in the tree.

The attributes Part.getFuelLinesFrom() and Part.getFuelLinesTo() can be used to discover these connections. In the example in Figure 5, when Part.getFuelLinesTo() is called on fuel tank part 11, it will return a list of parts containing just fuel tank part 9 (the blue part). When Part.getFuelLinesFrom() is called on fuel tank part 9, it will return a list containing fuel tank parts 11 and 17 (the parts colored green).

Staging ¶

Each part has two staging numbers associated with it: the stage in which the part is activated and the stage in which the part is decoupled. These values can be obtained using Part.getStage() and Part.getDecoupleStage() respectively. For parts that are not activated by staging, Part.getStage() returns -1. For parts that are never decoupled, Part.getDecoupleStage() returns a value of -1.

Figure 6 shows an example staging sequence for a vessel. Figure 7 shows the stages in which each part of the vessel will be activated. Figure 8 shows the stages in which each part of the vessel will be decoupled.
