The work is devoted to the rapid assessment of the weight of the aircraft and its design. This problem occurs when creating new aircraft or in the process of constructive improvement of existing ones. To determine the mass of the entire aircraft, the method of “mass change coefficients” (growth coefficients) is used, which is based on the equation of the existence of the aircraft. To analyze the mass of initial design changes, the Komarov weight formula based on the concept of “load-carrying factor” is used. The article considers a numerical example of estimating changes in the mass of an aircraft due to the use of composite materials in the fuselage structure.
