Abstract

The article is devoted to the development of the technology of sub-keel stiffness Assembly. Production of an airplane airframe begins with the manufacture of parts and ends with Assembly work of nodes, aggregates, docking and installation work on the finished product. Currently, one of the main elements of the productive process of manufacturing aircraft is considered Assembly production. The main factors that determine the specifics of Assembly work in aircraft construction are: the large number of parts of the airframe, as well as a wide variety of structural materials used. This leads to a variety of technological processes and equipment, complicates the planning, control and accounting of Assembly work; the complexity of production forms and low rigidity of most elements of the airframe design, which makes it necessary to use numerous and complex technological equipment; high requirements for the quality of the aircraft as a whole and its individual elements, which require the latest control methods, including special equipment; extensive cooperation of production significantly complicates the solution of issues of ensuring the accuracy and interchangeability of airframe design elements; frequent change of production facilities due to the rapid aging of aircraft equipment. The duration and complexity of Assembly work, depending on the type of aircraft, is from 30-56% of all production labor. Assembly and installation work includes airframe Assembly, installation of equipment and power plants, installation of flight control systems and take-off and landing facilities, airfield work to prepare the aircraft for flight tests and delivery to the customer. Assembly and installation works are characterized by the complexity of the work performed, a relatively low level of mechanization of technological operations of Assembly and installation, which entails a large labor intensity of manufacturing products, a low level of labor productivity. Assembly work can be divided into three types: node Assembly-Assembly of nodes (spars, ribs, frames, hatch flaps); aggregate - Assembly of compartments, units, sections of the airframe; General Assembly of aircraft - Assembly-docking of individual units into a whole product and leveling work.
