Question

please just show a small hint on how I can include these component on the design point please

please I know it might take your time and I am really sorry for that also I appreciate  the time and effort you will put onto this

thank you very much

A private space company wants to be the first to start mining in space. This could be the moon, asteroids or Mars. They need a robust (and ideally reusable) rocket for transporting equipment (and possibly people) to the mining base.

• Some of the design points are:

  1. The rocket should use Liquid Propulsion as it will make the rocket easier to be controlled and also make the rocket more reusable.

  2. Using Liquid Propulsion system will reduce the number of thrusters required for controlling the vehicle. We could use gimbal controls at the nozzle of the rocket to maneuver the rocket.

  3. We should use reliable components during the engineering of the rocket, to make sure the components can undergo stress and strain for many times repeatedly and can be readily used again and again.

  4. We could use pyrotechnics and parachute based system to control the speed of the rocket when it is landing back.

Answer 1

Energy: In Liquid Propulsion, usually liquid hydrogen and liquid oxygen are used. They are ignited together leading to a conversion of the chemical energy in the atoms to the kinetic energy of the atoms. They shoot out of the rocket leading to a change in momentum of the rocket and it pushes the rocket forward.

Thermodynamics: The combustion chamber where the fuel is burnt will be reaching very high temperatures, and just besides that we have to keep the temperatures very low in the tanks above where liquid hydrogen and oxygen are stored. This involves applying thermodynamic principle to calculate amount energy flow...etc.

Matter/Materials: The materials near the above-mentioned case should be made in a way that they are very good insulators so there is not much heat flow between the combustion chamber and the fuel tanks above. Also, the material outside the capsule which makes reentry should be designed in a way to handle extremely high temperatures as the surface of the capsule will be getting heated as it is making a re-entry into the Earth's atmosphere.

Radiation: The radiation which will be falling on the Electronics must be calculated before hand it should be made radiation hardened so that the electronics functions without any fault.

Electrochemistry: We will be using fuel cells/ batteries to power the electronic circuits inside the rocket as well as the miner. So a proper calculation is required to select the battery which runs on the principles of the electrochemistry.
