Abstract: Technological methods for manufacturing cooling elements of modern rocket engines are considered. They are developed taking into account the possibility of reusable use, which reduces the cost of manufacturing similar products. It is shown that in this case, the thermal load on the walls of combustion chambers of liquid rocket engines increases significantly.

Abstract: Currently, there are several coatings used to protect various defense and space crafts, however, they fail to perform in extreme environments due to limitations in that they are designed and in operation for specific environments. While existing materials like aluminum alloys, steels, magnesium alloys and titanium alloys suffer from surface oxidation, mismatch of thermal expansion coefficients, corrosions and poor mechanical strength, new research verified through the US Army’s Future Vertical Lift initiative shows that two carbon-based nanomaterials - two-dimensional fluorinated graphene oxide (FGO) and nanocrystalline diamond (NCD) - are amongst the most promising electro-optic materials to be applied to air and space crafts.

Abstract: The aim of the study is to perform FE Analysis using ANSYS for the Honeycomb sandwich structures with varying skin thickness ranging from 0.5 to 2 mm and edges of the honeycombs are converted into curve shapes to avoid any stress concentration at the intersection. The study of the natural frequencies of the structure is also carried out. The core structure is made up of Aluminum alloy and the skin or face sheet is made up of carbon fiber and the properties are been
