Basic Design - Atomic Rockets
Everything about fundamental spacecraft design revolves around the Tsiolkovsky rocket equation.. Δ v = V e * ln[R]. The variables are the velocity change required by the mission (Δ v or delta-V), the propulsion system's exhaust velocity (V e), and the spacecraft's mass ratio (R).Remember the mass ratio is the spacecraft's wet mass (mass fully loaded with propellant) divided by the dry mass

The two shipsItalia and Lepantowere designed by Benedetto Brin, who chose to discard traditional belt armor entirely, relying on a combination of very high speed and extensive internal subdivision to protect the ships. This, along with their armament of very

BOILERS | Energy-Models.com
Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

Coal - Wikipedia
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.
