| Abstract |
To study the influence and selection of rational elastic-dissipative parameters for under wing pylon-mounted engine suspension, a mathematical model of aeroelasticity of a large-sized transport aircraft has been developed by taking into account the kinetic moment of the engine rotors and specially designed engine attachment points to the pylons. It is shown that the elastic-dissipative parameters of the attachment points, which implement the concept of a released engine, have a significant effect on the integral aeroelastic and strength characteristics of the aircraft. Schematic diagrams of the engine mounts to the pylon are proposed. The usefulness of the concept of a released engine for increasing aeroelastic stability and reduce the level of fatigue damage of the aircraft structural elements has been proved. |
