"To burn" is a colloquial term used to describing use of a rocket.
Travel between natural satellites of the planet or between a planet and its satellites.
Overcooling a reactor
* Loss of codex:thrust due to insignificantly heated codex:propellant. * codex:Electrical power shortages due to insufficient heat and pressure provided to power plant.
All codex:reactors are equipped with mechanisms to regulate the temperature to prevent both overheating and codex:overcooling and in normal operation excessive temperature is not a risk. Damaged reactor may however lag behind, causing temperature to fall or rise above rated operating threshold.
Excessive temperature poses a great risk to the codex:spaceship. Symptoms of overheat include:
* With low overheat risk of codex:turbine galling. * With moderate overheat risk of codex:explosive reactor decompression. * With severe overheat risk of codex:meltdown.
Methods of preventing overheat:
* Maintaining fuel rod actuators in proper working order. * Venting excessive remass with simultaneous RCS codex:burns.
Reactive Mass, or propellant, it what enables the ship to move. Only way to move in space it to eject something in opposite direction. The faster the codex:exhaust velocity the less propellant you need to maintain same codex:acceleration.
The propellant economy measures how much codex:propellant the rockets uses for a codex:burn. It's usually measured by __kg/s__ or __g/s__ for smaller thrusters. Better (smaller) propellant economy will allow longer missions on same codex:propellant tanks.
The propellant economy is improved by:
* Higher codex:exhaust velocity and codex:specific impulse inherent to the rocket. * Lower codex:thrust.
The propellant economy is degraded by:
* Lower codex:exhaust velocity and codex:specific impulse inherent to the rocket. * Higher codex:thrust.
Most thermal rockets in the rings use water as a reactive mass, due to it's abundance in codex:Saturn's system.
Modern ships can be retro-fitted with various sizes of codex:propellant tanks, ranging from close-range to interplanetary-capable.
Increasing the size of your tank will prolong your available codex:ringdive time, but at the same time added mass will make the ship less manouverable.
Railguns are simple mass accelerators requiring physical contact of the projectile with guiding rails. Projectile closes the electric circuit and induces electromagnetic force that propels it. Compared to more complex codex:coilguns, railguns are relatively simple devices capable of delivering impressive rate of fire, but they lose a lot of efficiency due to friction of the projectile and are prone to malfunctions.
Railguns require codex:kinetic ammo storage to function.
Reaction Control System
RCS thrusters are the main method of propulstion during codex:ringdives. A set of relatively small engines positioned in key location of a codex:spaceship can be used to precisely control movement and orientation of the craft.
Both codex:fission and codex:fusion reactors provide heat directly, through the respective nuclear reaction. Production of the codex:electrical power from the supplied heat is performed by codex:turbines, codex:magnetoplasmadynamic genrators or codex:thermoelectric generators in small crafts.
A colloquial term for a excavation mission in the Rings of Saturn.
Structure of a ringroid will range from ball of ice to loosely-packed snow and effect of impact is not predictable. Ringroids in the A Ring are know to contain unusually high concentration of ore chunks.
Ships utilizing skyscraper layout will have decks aligned paralel to the engine-tip axis of the ship. When ship codex:burns forward, the apparent "up" will be along the direction of acceleration.
A permanent orbital habitat, designed for prolonged occupation.
Notable stations of Saturn's system
Able to provide crew safety in space travel.
Specific impulse (Isp) of a rocket determines it's codex:propellant economy. The higher the specific impulse the less propellant will your rocket consume to provide same acceleration - it will however need much more power, both thermal and electric to maintain the codex:burn.
The exhaust velocity usually measured in __s__.
Exhaust velocity is directly proportional to codex:exhaust velocity and the terms are used interchangeably.
Most prevalent ring system of the Sol, rings contain codex:ringroids with mass equivalent of small moon. With thickness ranging from dozens meters to few kilometers, rings span enormous surface area and are valued resource of rare earth minerals discovered during codex:asteroid impact of 2184.
Thermal power is produced by codex:spaceship's nuclear codex:reactor directly through codex:fission or codex:fusion. Heat is usually consumed by codex:RCS thrusters, codex:main engine to propel the craft.
If propulsion power consumption will exceed your reactor heat output, spaceship risks codex:overcooling the reactor.
Thrust is the measure of propulsive power of the rocket. The higher the thrust the more acceleration will the rocket provide to a codex:spaceship of same mass.
Thrust is measured in kN.
Higher thrust will demand more thermal and codex:electrical power from the codex:reactor. The power requirements can be negated by decreasing codex:specific impulse and codex:exhaust velocity at cost of degraded codex:propellant economy.
Electrical turbine is a common power plant used by codex:spaceships.
Simple and reliable, it uses pressurized codex:supercritical codex:propellant directly from codex:reactor core to produce codex:electrical power. The propellant is vented in an codex:open cycle cooling.
While turbines provide relatively low power output, they are reliable and don't require any initial power to operate.
