The effect of airspeed on the geometric appearance of the mainline aircraft

Abstract

Modern needs when forming key technologies for the creation of high-speed mainline aircraft can be divided into following seven groups covering the basic technical aspects: ensuring an acceptable level of acoustic impact while simultaneously ensuring the required aerodynamic efficiency by creating an integrated construction arrangement of the aircraft; ensuring the target fuel efficiency of the power plant and permissible harmful emissions at supersonic airspeeds while meeting the requirements by noise level at take-off and landing modes; ensuring the target values of the weight and resource efficiency of the aircraft structure while ensuring the required rigidity and aeroelasticity; ensuring reliable stability and controllability in all flight modes; increasing the reliability and functionality of the onboard equipment and systems under kinetic heating conditions; improving the efficiency of onboard systems based on more effective electric aircraft technologies; participating in the creation of international requirements and standards for certification and the operation of new generation aircraft.
