Thrusters/es

Los propulsores son lo primero que se habla sobre las naves, toda nave o estación lo utilizan para moverse. Los propulsores solo proveen de un empuje linear dependiendo de su posicion fisica en la nave, esto no aplica por el toque o giro provocado por la nave mediante un eje de rotación (ver Gyroscope/es).

Actualmente todos los tipos de propulsores (Ya sea para pequeñas o grandes naves) no tienen ninguna capacidad especial super amotiguadora mas allá de su maxima capacidad o consumo de energía.

Propulsor de iones (Electrico)

All standard Electric-based Ion thrusters will consume a minimum of 0.002 kW (2 Watts), even when not in use. They use electricity to generate thrust, their power consumption scales linearly with what percentage (as seen on the thrust override slider) the thruster is operating at. It's effectiveness is inversely dependent on the density of the atmosphere, having an actual effectiveness anywhere from 30% at minimum to full effectiveness outside planetary atmospheres - becoming increasingly less effective the thicker the atmosphere.

Propulsor de Hidrogeno

All Hydrogen-based thrusters require a Conveyor connection to a source of Hydrogen such as an Oxygen Generator or a Hydrogen Tank. (*) Hydrogen based Thrusters despite having a 'power consumption' rating will not actually consume electrical power they ONLY consume Hydrogen from a hydrogen source accessed via conveyors. Their only electrical requirements will be for the hydrogen sources that store or make hydrogen and the Conveyor system. Each Hydrogen Thruster consumes a tiny amount of Hydrogen even if not active (as seen with its 'pilot light'), much like the minimum that electric-based thrusters have. Their effectiveness is entirely unaffected by the presence of planetary atmospheres, being equally effective everywhere.

Propulsor Atmosferico

All atmospheric thrusters thrust output is entirely dependent on the density of the atmosphere around the thruster and only work in planetary atmospheres, being most powerful near the surface and becoming linearly less powerful further out. Typically the thruster will never achieve it's rated maximum during usual play even directly on the surface (which is typically around 90% max efficiency). They much like standard thrusters use electricity to function and consume a minimum amount of 0.002 kW (2 Watts) even when not in use.

Efectividad en gravedad natural

To get an idea how many thrusters are needed to make a ship hover in the air while under the influence of natural gravity,
the following calculation should help:

 Lift [kg] = engine force [N] * effectivity [unitless] / acceleration due to gravity [m/s²]

Example: 1 large small ship thruster has a force magnitude of 408,000 N at sea level. (Here an effectiveness of 90% is assumed.)
So on an earth-like planet on sea level it can lift:

 L = (408,000 N * 0.9) / 9.81 m/s² = 37,431 [kg]

Where 9.81 m/s² = 1.0 g on Earth.
Or to just check if it will fly with 4 thrusters and a mass of 120,000 kg:

 F = (4 * 408,000 N * 0.9)
 m = 120,000 kg
 a[min] = 9.81 m/s²
 a[curr] = (4 * 408,000 * 0.9) / 120,000 kg = 12.24 m/s² > 9.81 m/s² ===> will fly!

So if the ships downward thrusters total lift is greater than the ships mass,
the ship will be able to hover and fly.

This value decreases linearly with the decreasing air density in greater heights. The air density is different for each planet type. As is the natural gravity constant.

Online calculator: Online calculator to calculate the thrust at planets and moons.

Note: One should also keep in mind, that depending on the ships orientation during maneuvering, not all downward thrusters will actually contribute 100% to the ships lift.
If the thrusters are angled away from the the planets center of gravity, their effective lift value will decrease accordingly. A thruster angled at 45 degree will only contribute 70.71067812% (cos45x100%) of its total force for lift. If not taken into account, this can make a ship plummet to the ground when not maneuvering it carefully
due to insufficient lateral thruster force when rolling the aircraft too much for example. So this should be calculated or tested before actually finishing a ship design to prevent a bad surprise.

Note2: The "x5" / "x10" inventory setting will also have an effect on the calculation.
The game will divide the cargo mass by the set inventory multiplier when calculating thruster lift.
So a cargo mass of 100,000 kg will only count as 10,000 kg if "x10" inventory multiplier is set.
This means, a ship with atmospheric thrusters can potentially lift 10 times more cargo mass with the same thrust than it normally could, if a "x10" inventory multiplier is set.
However, the right HUD panel when inside of a ship doesn't correct the cargo mass to reflect the mass taken into account for lift.
So that means, when having a ship with net mass of 100,000 kg and transporting 100,000 kg of cargo with a 10x inventory multiplier,
the panel will show 200,000 kg of mass while in reality it will take only 110,000 kg (ship mass + cargo/10) of mass into account for calculation of lift ability.

Daño de los propulsores

If 'Thruster Damage' is enabled for a map or server, thrusters will deal damage while active to any blocks directly behind within a certain distance with exception to small thrusters damaging large ship blocks, making it possible to build 'landing pads'. If this occurs, blocks adjacent to the block/s in "the line of fire" will also be damaged in a cross-pattern. If the block is too close to the thruster, this can even damage the thruster, causing it to explode. The "danger zone" varies in size based on the thrust being applied by the thruster. Large thrusters deal damage further than small thrusters. Likewise, thrusters on large ships deal damage further than those on small ships.

This table (and the images below it) indicate the damage distances for small and large thrusters and ships. They apply only to blocks directly behind the thruster, and do not account for damage to adjacent blocks.

All thrusters from standard thrusters, hydrogen and Atmospheric deal thruster damage to varying degrees if enabled, generally the more powerful the thruster the larger the danger zone becomes.
