Detailed Description

Represents a complete rocket vehicle composed of stages, motors, and recovery systems.

The Rocket class encapsulates the full vehicle configuration, including mass properties, center of gravity (CG), center of pressure (CP), and stability margin calculations. It is the central object for design, simulation, and flight state management.

Constructor & Destructor Documentation

Rocket()

Rocket::Rocket

(

const std::string &

name

)

Constructs a new Rocket with a given name.

Parameters

name	The name of the rocket.

~Rocket()

Rocket::~Rocket ( )

default

Default destructor.

Member Function Documentation

addStage()

void Rocket::addStage

(

std::unique_ptr< Stage >

stage

)

Adds a new stage to the rocket.

Parameters

stage

A unique_ptr to the Stage object to add.

applyFlightState()

void Rocket::applyFlightState

(

const FlightState &

state

)

Applies a given flight state to the rocket.

Intended for advanced simulation stages, including 6-DoF dynamics.

Parameters

state

The current flight state.

getCenterOfGravity()

double Rocket::getCenterOfGravity

(

)

const

Returns the current center of gravity (CG) of the rocket.

Returns

Distance from reference point (e.g., nose tip) in meters.

getCenterOfPressure()

double Rocket::getCenterOfPressure

(

)

const

Returns the current center of pressure (CP) of the rocket.

Returns

Distance from reference point (e.g., nose tip) in meters.

getName()

const std::string & Rocket::getName

(

)

const

Gets the name of the rocket.

Returns

Rocket name as a constant reference.

getStabilityMargin()

double Rocket::getStabilityMargin

(

)

const

Calculates the rocket's stability margin.

Defined as the normalized distance between CG and CP. Positive margin indicates stable configuration.

Returns

Stability margin (calibers).

getStages()

const std::vector< std::unique_ptr< Stage > > & Rocket::getStages

(

)

const

Returns a const reference to the list of stages.

Returns

Vector of unique_ptr to Stage objects.

getTotalMass()

double Rocket::getTotalMass

(

)

const

Returns the total mass of the rocket (including all stages and payloads).

Returns

Total mass in kilograms.

getTotalPropellantMass()

double Rocket::getTotalPropellantMass

(

)

const

Returns the total remaining propellant mass of all motors.

Returns

Propellant mass in kilograms.

prepareForFlight()

void Rocket::prepareForFlight

(

const Environment &

env

)

Prepares the rocket for flight simulation.

Typically called once at simulation setup to adjust for environmental conditions.

Parameters

env	The environment (atmospheric conditions) at launch.

setName()

void Rocket::setName

(

const std::string &

name

)

Sets the name of the rocket.

Parameters

name	The new name.

updateMassProperties()

void Rocket::updateMassProperties

(

)

Recalculates total mass, CG, CP, and stability margin.

Should be called after any modification to the rocket structure.
