Abstract
This work contains materials obtained at the preliminary stage of studying and improving the designs of low-flow reciprocating compressors of medium and high pressure with a traditional crank-and-rod movement mechanism and an understudied linear drive. The structures under consideration are intended for use in gas supply systems for rocket and space complexes, life support for naval facilities, and in military aviation. The results of the computational analysis of working processes and integral parameters of the stages of reciprocating compressors with a developed internal heat-exchange surface of the cylinders are presented. Reducing the negative impact of the increase in the temperature of the injected gas in the stages is supposed to be achieved through the use of stages with cooled heat exchangers built into the cylinders with a developed heat-exchange surface. The computational analysis was performed on the basis of the KOMDET-VKA program.
