Abstract


The article’s subject is the design preparation for producing light general aviation aircraft. This article aims to develop design solutions for a light cheap aircraft with low flight and ground costs, to substantiate the possibility and necessity of using modern CAD systems and new plazless methods to ensure the interchangeability of light aircraft components to reduce design and production costs. Objective: to analyze the global demand for light aircraft, to substantiate the possibility and feasibility of introducing independent (plazless) methods for linking technological equipment and aircraft design components, to develop a list of design work and expected results, to develop digital models (electronic drawings) of the aircraft as a whole and its components, to prove the effectiveness of such approaches. The research methods used are the analysis of scientific and technical documentation, numerical modeling of the aerodynamic flow around the aircraft, the stress-strain state of the units, and the design of the aircraft and its components considering the results of numerical modeling. The following results were obtained: a set of digital models (electronic drawings) of the whole aircraft, a fuselage, a wing, a horizontal and vertical tail, a chassis, digital models (electronic drawings) of the aircraft parts. The scientific and practical novelty of the obtained results is as follows: a set of aircraft design engineering documents developed based on statistical data analysis and numerical modeling will allow manufacturing, testing the aircraft, and obtaining a certificate of airworthiness, which, in turn, will make it possible to subsequently begin serial production of the aircraft and create full-fledged primary flight training classes designed to improve flight training activities for cadets of higher military educational institutions and create opportunities for training civilian pilots.
