Procedure of the transport aircraft landing gear preliminary design
The article describes the main stages of transport aircraft landing gear designing, provided an example of the scheme development, structure and design, as well as the constituent elements of the chassis, which should ensure the most efficient design. Preliminary design of chassis is systemized and described by the procedure. The schemes, structures and construction and also the elements of landing gear of the modern transport aircrafts (TA) are considered at this work. The strength design shows that the landing gear construction satisfy the common and strength requirements for TA. The procedure of the preliminary design of TA landing gear is developed in this article. The developed algorithm of comparison of the initial data with statistic data covers the exchange of data with the project data base. In addition, the possibility of data exchange with project models and, particularly, with the common airframe finite-element model permits the deflate of the input data number and provides the automatically binding of the landing gear attachment fittings to the airframe power elements. The developed procedure is systemized data by landing gear design of TA, reduce the time of the basic parameters landing gear definition and reduce the error probability.
