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 ...
Unsteady vortex lattice aerodynamics for rotor aeroelasticity in hover and in forward flight
(Georgia Institute of Technology, 1989-12)
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 ...
Development and application of a generalized dynamic wake theory for lifting rotors
(Georgia Institute of Technology, 1989-08)
Aeroelastic optimization of a composite tilt rotor
(Georgia Institute of Technology, 1999-05)
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 ...
Determination of the structural dynamic characteristics of rotor blades and the effect of phase angle on multibladed rotor flutter
(Georgia Institute of Technology, 1975-05)
Jet thrust as a counter-torque force for single-rotor, shaft-powered helicopters
(Georgia Institute of Technology, 1961-08)
An experimental determination of the motion of a vortex sheet in the wake of an isolated two-bladed hovering model helicopter rotor
(Georgia Institute of Technology, 1958-12)
