Kerbal X/es
El Kerbal X es un cohete disponible para todos los jugadores. Es una nave confiable capaz de llegar a órbita fácilmente y por esto es una buena nave para los nuevos jugadores que no sepan construir sus propias naves para hacerlas llegar a órbita. Tiene una masa total de 131.62 t y tiene 74 partes. Deberías saber que la versión que tienes en almacén no tiene SAS o ASAS a bordo, así que se recomienda añadir uno. Tampoco tiene propulsores RCS.
Despegue
La primera etapa esta compuesta de tres Rockomax X200-32 Fuel Tanks y un Rockomax "Mainsail" Liquid Engine. También, seis quemadores de combustible liquido en un Asparagus design. Tiene superficies aerodinámicas y una fuerte estructura. La primera etapa puede servir facilmente para lanzar a la segunda etapa en una trayectoria parabolica, con una buena velocidad horizontal alrededor de 90km, haciendo fácil para que la segunda etapa llegue a órbita. La etapa completa con todos sus quemadores tiene 2700 kN de propulsión, para una radio de propulsión a peso (TWR) de 20.51. La sola Mainsail y su tanque de combustible tiene un TWR de 21.36 (la masa total de Kerbal X entonces es de 70.02 t).
La segunda fase es un Rockomax X200-16 Fuel Tank de largo diametro además de un Rockomax "Poodle" Liquid Engine, y la tercera, y final se compone de solo un Mk1-2 Command Pod con un Mk16-XL Parachute. La segunda etapa tiene también patas de aterrizaje y una escalera, se deduce que se podría llegar a Mun. Es capaz de llegar, pero desafortunadamente no podría haber viaje de vuelta a casa.
Especificaciones
El quemador central de la primera etapa tiene un combustible con 3177 m/s de ΔV, sin mencionar que el anillo radial de los quemadores tiene aproximadamente 1003 m/s. Esto suma casi 4180 m/s, casi suficiente para llegar a órbita (4500 m/s), haciendo que la Kerbal X sea una opción factible para orbitar.

making the Kerbal X a suitable option for orbiting small payloads. These payloads, for a proper orbit, autonomous propulsion would be require to achieve orbit (320 m/s). Such payloads should be less than 16.7 t to keep the standard configuration of the rocket. Still, if one would be willing to use the Kerbal X first stage as a launcher, the maximum weight of this assembly would be 68.1 t of mass, as this is the minimal weight for a 2.2 TWR, which is seen as the acceptable ratio of a rocket. Note that in this situation, the first stage derived from the Kerbal X wouldn't have 4180m/s as the mass to carry is significantly bigger and as such wouldn't prove as efficient.
The second stage has 2494 m/s Δv, and the total Δv is 6674 m/s.
Potential uses
| Action | Δv (m/s) | Feasible |
|---|---|---|
| Orbit | 4500 | Sí |
| Munar Injection | 910 | Sí |
| Mun Landing | 1000 | Sí |
| Mun surface orbit | 700 | No |
| Mun orbit return | ? | No |
| Minmus Injection | 1010 | Sí |
| Minmus Landing | ? | ? Unkown |
| Solar orbit injection | 1400 | Sí |
| Interplanetary travel | ? | No |
The ability of the Kerbal X to reach orbit with a relatively small rocket for a medium payload (16 t), is significant in its reliability as bigger rockets tends to be more prone to exploding randomly or being unsuited for space travel. The two-stage to orbit leaves no debris and could be economically healthly when in-game budget is implemented.
Interesting use of the Kerbal X, with added SAS, RCS and a docking port, is a space station docker, allowing crew transfers or module delivery and docking as the ship has a good marge of additionnal weight it can carries. If placed properly, the RCS thrusters assures an easy docking and the low chance of failure justifies the uses of the Kerbal X as a crew transfer ship has the chance of seeing the crew being killed near zero.
Another uses of the Kerbal X would be to land on the Mun, with added basic functionnalities such as RCS, SAS and docking port, it would be fairly easy to refuel the ship in Kerbin orbit, possibly with another Kerbal X, and fly it to the Mun, land and eventually come back, or at least, go back to Munar orbit.
If one would be willing to be upgrade the Kerbal X, adding a small intermediate stage that can almost finish orbit would be a big increase in performance as 12% of the fuel is used to finish orbit in optimal situation (accounting you used exactly 4500m/s to make orbit). Of course, one willing to use the Kerbal X often must absolutely add both RCS and SAS.
The Kerbal X would also be suited to place payloads in geosynchronous orbit as it has the required Δv to do so and deorbit thereafter.
