The paper presents fundamentals of the passenger aircraft supersonic dynamics. Basic information about design and technical characteristics is given, typical parameters of supersonic passenger aircraft are considered and main issues of their design are highlighted. Images are presented of the promising supersonic aircraft, which have competitive advantages due to the best technical, economic, operational and environmental performance. Key areas in ensuring design and development of the domestic supersonic passenger aircraft (SPA) of the next generation are given including the advanced scientific and technical solutions. It is postulated that acceptable ecological performance of the new generation SPA is necessary due to significant tightening of the national and international requirements to ecological characteristics of the civil aviation aircraft, namely in the context of the problem of minimizing harmful effects of the supersonic passenger aircraft on the environment. Ways are considered to ensure acceptable level of the sonic boom during flight at the supersonic cruising speed, compliance with noise standards in the airport area and in reducing harmful emissions into the atmosphere. All this requires searching for new technical solutions, comprehensive analysis and selection of the most rational options for the SPA airframe aerodynamic scheme and its power plant. Russian and foreign scientific research, design and development works on the supersonic topics were analyzed. Economic efficiency of the civil aviation aircraft operation is considered with the prospect of flying at the supersonic speed. Difficulties in design and development of a supersonic passenger aircraft are noted. Contradictions that arise during design and development are shown. Namely, selection of the correct model for the aviation industry plays an important role and in most cases becomes the basis for taking an approach to solving a particular problem.

Prospects for development of modern supersonic passenger aircraft

The paper focuses on reducing sonic boom by optimizing the aerodynamic configuration of the aircraft, as well as the forebody parameters. The study emphasizes the urgency of the problem of sonic boom generated by a supersonic business aircraft and introduces the database acquired from research into methods for reducing sonic boom, both as an individual problem and as part of multi-parameter optimization of a supersonic business aircraft. We systematized and processed the data and estimated the methods in terms of their influence, if applied, on the level of sonic boom. Furthermore, we matched each method to the aircraft design stages that are characteristic of its introduction into the configuration. This approach makes it possible to find layout solutions and assess them rapidly at the early stages of designing the configuration of this kind of aircraft.
