The research studied optimal arrangement of rocket fuel tanks of minimum starting
weight with preserving the stability. We paid the main attention to calculating the
strength and stability of the tank shells, determining their thickness in the two layout op-
tions: oxidizer – fuel, fuel – oxidizer. First, we calculated the weight of the obtained
structure in both cases, analyzed the extension of centre of pressure and centre of mass.
Then, we made a comparison of the weight value obtained from the strength calculation,
with the value adopted in the statistics design. Moreover, we proposed a solution to the
problem of static rocket instability by installing lattice stabilizers and we showed the ad-
vantage of the obtained design in a weight ratio. Finally, we proved the benefits of plac-
ing the oxidizer tank behind the fuel tank, which makes it possible to create lighter rock-
ets and increase the payload mass without increasing the general product weight.
Keywords:
tank, weight coefficient, fuel, arrangement, voltage, oxidant, lift, tension, oxidizer,
lift force, strength, extension of centre of pressure and centre of mass, carrier-rocket, com-
pressive force, stabilizer, starting weight, shell thickness, fuel compartment, stability.
