Revision as of 13:16, 5 April 2015

This tutorial gives - by some step by step building exercise - the basic knowledge of rocket-building and some kind of craft used as a payload, and teaches the necessary usage of the editor - except the career-dependent details.


For doing this tutorial start a game in sandbox mode, and enter into the Vehicle Assembly Building in the KSC.

The first step of the rocket building is defining the purpose of the rocket, because this purpose determines the terminal stages act as payloads, which size and weight and destination determines the requirement of interplanetary and middle stages, and finally the total weight of these stages hedges in the parameters of the possible launch vehicles. As a result of this, the most practical way of constructing the rocket is starting with the final stage(s), and build it from up to down.

The controlling part of the rocket - and the functions of the editor

The proper command module

The command module practically placed on the final stage, because such a way it can control the craft from the launch till the end during the mission. For the manned missions cabins holding kerbonaut(s) are needed. For a mission needs a single kerbonaut a Command Pod Mk1 is enough, but if we want to make a mission with full crew (pilot, engineer and scientist), an Mk1-2 Command Pod is necessary. The presence of an experienced pilot can be compensated with installation of a proper probe core. For the manned missions the return of the crew has to be ensured, so if there is no a separate vehicle for bringing our heroic kerbonauts back to Kerbin, this stage has to be functional as a returning unit. For launching a radically new rocket not tested yet, avoiding the loss of kerbonauts a Launch Escape System (LES) has to be installed on the cabin too.

If the rocket's role is delivering a remote craft, that craft's probe core can control the whole rocket. If the payload would has no a probe core (refueling unit), then a it has to be built in the final stage of the basic construction.

The crafting of cabins' stage - and what the editor gizmos for

Well, let see the building of a cabin equipped with a LES. There is a proper sized Launch Escape System as a special part for the big cabin fitting on 2.5m rockets, but we have to compose a such device for Mk1 cabin. Now, lets build this module, just for learning.

We have to start with placing the command module. Switch the mode control - if it is not in this state - to Parts mode, and change the bar's page to Pods (first from uspide), and select the Mk1-2 Command Pod, and place it somewhere in the workshop. As it has been done the icons of the editor gizmos appear. The sorting preference of the parts can be changed by clicking on the labels of Name, Mass, Cost and Size situated on the top of the parts' bar.

The Launch escape system has to be placed on the top of the cabin, where the parachute used to, such as the Mk16 Parachute with its 0.625m radial size fits perfectly on Mk1 cabin, or Mk16-XL Parachute and Mk25 Parachute (1.25m) fits on the Mk1-2. In this case, an group of Mk2-R Radial-Mount Parachutes must placed on the surface of the cabin symmetrically. The situation is similar when docking ports is installed on the top for availability of the docking later. Due to the launch escape system means unnecessary extra weight during the spaceflight, it worth to decouple after the initial sequence of ascending - so it has to be installed on a decoupler, separator, or a kind of the mentioned docking ports.

For the radially symmetric placement switch the symmetry indicator to radial symmetry position, if it is in lateral symmetry mode. Switching is possible between these modes by pressing R, the number of the symmetrically placed parts can be increased by clicking on the indicator or pressing X, an decreased by right-clicking on the indicator or pressing Shift+X. Lets place two Mk2-R Radial-Mount Parachute (Utility group in the parts' bar) in radial symmetry on the cabin.
