Abstract
This article discusses the components, schemes, designs and chassis designs of modern transport aircraft. The strength calculation shows that the chassis design meets the general and strength requirements for transport aircraft. The article will develop a procedure for preliminary design of the chassis of transport aircraft. The developed algorithm for comparing the source data with statistical data provides for data exchange with the project database. In addition, the possibility of exchanging design data allows you to dramatically reduce the amount of data entered into the model, in particular, into the general elementary model of the airframe, and provides automatic connection of the chassis mounting units with the airframe batteries. The developed procedure systematizes the data, reduces the time to determine the main parameters of the chassis and reduces the likelihood of errors.
