Problems of engineering aerospace equipment units operating in extreme temperature conditions are analyzed. Engineering approaches to the calculation of parameters of mating parts made of materials with different thermal-expansion coefficients are suggested. It is shown that design solutions based on using of resilient flexible elements allow to maintain minimum positive and negative allowances in matings in a wide range of exterior temperature variation
