Main Rotor Wake Interference Effects on Tail Rotor Thrust in Crosswind
International Journal of Aerospace Engineering, 2021 Reverse pedal operational property in front crosswind flight condition is a potential hazard for accidents involving loss of tail rotor effectiveness (LTE), which is closely related to the main rotor (MR) wake interference on the tail rotor (TR).

Numerical analysis for main-rotor/tail-rotor interaction of helicopter
Numerical analysis for main-rotor/tail-rotor interaction of helicopter, 2008 A simulation method for full helicopter configuration is constructed by combining an unsteady Euler code and an aeroacoustic code based on the Ffowcs-Williams and Hawkings formulation. The flow field and helicopter noise are calculated using a moving overlapped grid system, and the mutual effect of main rotor and tail rotor are studied for the ...
