Preliminary Turboshaft Engine Design Methodology for Rotorcraft Applications
(Georgia Institute of Technology, 2006-11-20)
In the development of modern rotorcraft vehicles, many unique challenges emerge due to the highly coupled nature of individual rotorcraft design disciplines therefore, the use of an integrated product and process development ...
Aeromechanical Stability Augmentation Using Semi-Active Friction-Based Lead-Lag Damper
(Georgia Institute of Technology, 2005-11-23)
Lead-lag dampers are present in most rotors to provide the required level of damping in all flight conditions. These dampers are a critical component of the rotor system, but they also represent a major source of maintenance ...
Analysis Of Computational Modeling Techniques For Complete Rotorcraft Configurations
(Georgia Institute of Technology, 2006-04-11)
Recent increases in computing power and memory have created renewed interest in alternative grid schemes such as unstructured grids, which facilitate rapid grid generation by relaxing restrictions on grid structure. Three ...
Investigation of a stop-fold tiltrotor
(Georgia Institute of Technology, 2009-07-09)
In 1967 the US Air Force solicited proposals for ``low-disc-loading [Vertical Takeoff and Landing] configurations suitable for high speed flight.' Bell Helicopter elected to respond with a proposal after initial analysis ...
A multi-fidelity framework for physics based rotor blade simulation and optimization
(Georgia Institute of Technology, 2008-11-17)
New helicopter rotor designs are desired that offer increased efficiency, reduced vibration, and reduced noise. This problem is multidisciplinary, requiring knowledge of structural dynamics, aerodynamics, and aeroacoustics. ...
A physics based investigation of gurney flaps for enhancement of rotorcraft flight characteristics
(Georgia Institute of Technology, 2010-03-26)
Helicopters are versatile vehicles that can vertically take off and land, hover, and perform maneuver at very low forward speeds. These characteristics make them unique for a number of civilian and military applications. ...
