A Perspective on Modeling Rotorcraft in Turbulence
Probabilistic Engineering Mechanics, 1987The turbulence as experienced by a blade station requires a non-Eulerian and rotationally-sampled description and it is referred to here as the rotating frame turbulence or RFT. The stationary RFT spectral densities show large peaks centered about the integer multiples of rotor speed (1P, 2P etc.).

Aeroelastic problems of Rotorcraft
1989In this chapter we will examine a number of aeroelastic phenomena associated with helicopters and other rotor or propeller driven aircraft. Certain areas have been selected for treatment to illustrate some significant stability problems which are associated with the design of helicopters.
