Dynamic Wake Distortion Model for Helicopter Maneuvering Flight
(Georgia Institute of Technology, 2005-04-10)
A new rotor dynamic wake distortion model, which can be used to account for the rotor transient wake distortion effect on inflow across the rotor disk during helicopter maneuvering and transitional flight in both hover and ...
Helicopter Blade Tip Vortex Modifications in Hover Using Piezoelectrically Modulated Blowing
(Georgia Institute of Technology, 2004-12-01)
Aeroacoustic investigations regarding different types of helicopter noise have indicated that the most annoying noise is caused by impulsive blade surface pressure changes in descent or forward flight conditions. Blade ...
Enhancement of aeroelastic rotor airload prediction methods
(Georgia Institute of Technology, 2009-04-02)
The accurate prediction of rotor air loads is a current topic of interest in the rotorcraft community. The complex nature of this loading makes this problem especially difficult. Some of the issues that must be considered ...
Extension-Twist Coupling Optimization in Composite Rotor Blades
(Georgia Institute of Technology, 2005-12-15)
For optimal rotor performance in a tiltrotor aircraft the difference in the inflow and the rotor speeds between the hover and cruise flight modes suggests different blade twist and chord distributions. The blade twist ...
Formation and evolution of tip vortices of an isolated rotor in forward flight
(Georgia Institute of Technology, 2001-12)
