A Simple Analytical Model for Investigation of Fuselage-Rotor Interference

van der Wall, Berend G. and Wentrup, Marc and Rajagopalan, Ganesh and Jung, Sung N. and Yin, Jianping (2016) A Simple Analytical Model for Investigation of Fuselage-Rotor Interference. AHS International 72nd Annual Forum & Technology Display, 17.-19. Mai 2016, West Palm Beach, Florida, USA.

Full text not available from this repository.


A simple analytical model to account for fuselage-induced velocities at rotor blade elements and at rotor wake nodes is described. The method is applied to three different fuselages. Results obtained with a comprehensive rotor code show the fuselage effect on rotor trim controls, comparing the isolated rotor with inclusion of the fuselage for the same trim. This is compared to a simple analytical estimate of the fuselage effect using blade element/momentum theory.
