A novel trajectory generation and control architecture for fully autonomous autorotative flare
that combines rapid path generation with model-based control is proposed. The trajectory …

Autorotation maneuvers inherently offer little margin for error in execution and induce high
pilot workload, particularly as the aircraft nears the ground in an autorotative flare. Control …

The consideration of safety issues in the operation of helicopters involves the capability to
perform emergency descending maneuvers through the autorotation principle when the …

A control algorithm for autonomous helicopter autorotation is proposed and evaluated. The
algorithm consists of a multiphase control law with fuzzily defined transitions and provides …

Under the framework of the US/France Project Agreement (PA) on Rotary Wing
Aeromechanics and Human Factors Integration Research, ONERA and AED began to …

For many rotorcraft platforms, incorrect timing of the autorotation flare and deceleration
maneuvers may result in significant aircraft damage and injury to the crew, or worse. There …

The objective of this work is to develop an autonomous autorotation landing system for an
unmanned helicopter. Threedimensional autorotation flight paths are obtained from a …

RAPID selection of a suitable landing site is critical to the success of helicopter autorotation
following power loss or transmission failure. Numerous factors may influence a pilot's ability …

With the increased focus on the use of autonomous rotorcraft for safety critical tasks such as
resupply or casualty evacuation, response in the event of failures has become an important …
