МЕТОД ЗАГАЛЬНОГО ПРОЕКТУВАННЯ РЕГІОНАЛЬНИХ ПАСАЖИРСЬКИХ ЛІТАКІВ

Abstract

A method of general design of regional passenger planes for transportation of passengers, baggage, mail and cargo on domestic and international airlines with the possibility of operating on airfields with concrete and prepared unpaved runways is proposed. Airplane is designed to replace the outdated Tu-134 passenger aircraft in the fleet of airlines of the CIS and other countries. The concept of creating an aircraft using integrated design systems has been developed. The effect of the aircraft parameters on the aerodynamic and mass characteristics was taken into account, subject to the requirements for layout and flight safety. The range of variation of the aircraft modifications parameters has been determined. The method has been tested by comparing the obtained parameters with the regional passenger aircraft of the Antonov State Enterprise.The aircraft features a modern aerodynamic configuration and efficient engines. Modern flight and navigation equipment and radio communication equipment, the use of multifunctional indicators, electrical distant flight control system allowing them to be used on any airways, in simple and complex meteorological conditions, day and night, and on routes with high flight intensity at high comfort level of passengers and crew.Passenger comfort is provided at the average level of long-haul aircraft, and is achieved by a rational layout and composition of service rooms, deep ergonomic optimization of the overall and individual space of the passenger compartment. The aircraft fully complies with the AP-25 airworthiness standards.The main technical characteristics of the aircraft are comparable to the characteristics of the analogue aircraft of Embraer and Bombardier companies. In addition, the aircraft has several advantages, such as the ability to operate on aerodromes with poorly prepared and unpaved runways, the presence of a door-ramp, high engine safety from damage by foreign objects, a high level of passenger comfort and large luggage racks, high efficiency of operation; high level of competitiveness in the global market
