Aeroelastic Stability of Turboprop Aircraft: Whirl Flutter
Original language description
This chapter is focused on a specific type of dynamic aeroelastic stability phenomenon - whirl flutter. Whirl flutter is caused by the effect of rotating parts of a turboprop power plant (propeller and, gas turbine engine rotor). The chapter presents fundamental facts regarding the whirl flutter phenomenon, including a historical overview and information regarding the occurrence of whirl flutter in aerospace practice. After that, the physical principles of whirl flutter are explained using a simple mechanical system with two degrees of freedom. Next, an analytical solution to determine the aerodynamic forces caused by the gyroscopic motion on each of the propeller blades is provided and the influences of the main structural parameters on the whirl flutter stability are discussed. The second, practical part is focused on the experimental research of the whirl flutter phenomenon and on certification-related issues. The methodology of certification according to the FAR / CS 23 regulation standard is demonstrated on the example of a twin wing mounted tractor engine commuter aircraft.
