Aerodynamics of Gurney Flaps on a Wing in Ground Effect

Flight Control System of an Experimental Unmanned Quad-Rotor Helicopter

An autonomous robot with vertical take-off and landing (VTOL) capability could be useful for many applications including search and rescue, exploration in hazardous environments, monitoring, surveillance and investigation or even for intelligence. However design of a flight control system for a small UAV is a challenging task. Unlike in conventional aircrafts the control algorithm has to be imp...

Helicopter Rotor Unsteady Aerodynamics

Unsteady helicopter rotor aerodynamics are complicated. This paper reviews some of the fundamentals and newer developments of unsteady helicopter aerodynamics. Rotor flow is beautiful and complex. Visualizing rotor flow allows for an appreciation of the following theories and solution attempts as well as nature’s complexities. The flow through a helicopter rotor with forward motion is shown in ...
