st. Petersburg State University (SPbGU) have created a mathematical model to calculate the optimal thermal protection parameters for re-entrant spacecraft. In this respect informs It is emphasized that the RT formula takes into account all the conditions that arise around a rapidly moving object in an ordinary and diluted gas. According to the researchers, under these conditions, not only does the temperature change, but also the composition of the environment, which affects the operation of the equipment.
“The main features of the obtained boundary conditions are the ability to accurately interpret the effects of the physical interaction of a gas with the surface of a body and take into account the effect of interfacial heterogeneous chemical reactions,” said department head Elena Kustova. st. Petersburg State University, Department of Fluid Aeromechanics.
He stated that this mathematical model will allow designers to improve the spacecraft’s coverage. He said that reducing the thermal protection layer would increase the ship’s payload.
Before that, scientists from the Karolinska Institute in Sweden to solvethat microgravity in weightlessness can suppress astronauts’ immunity. The study was published in the scientific journal Science Advance.
