Tell biomechanical pilot model to contract their muscles to move the stick much like brain would.

What is it about?

We developed a detailed biomechanical model of a helicopter pilot's arm, including all muscle bundles that drive its motion, and mapped the muscle activation to the activation pattern that is required to control the position of the collective control inceptor. Then, based on what maneuver the pilot wants to make, we activate the muscles to obtain the required collective control inceptor in a feedback loop. Both the pilot's biodynamics and the helicopter aeromechanics are modeled within MBDyn, a single general-purpose multibody dynamics framework.

Why is it important?

Detailed simulation of both detailed pilot biomechanics and detailed helicopter aeromechanics while performing complex voluntary tasks. Blends voluntary, behavioral pilot models with biomechanics that is at the roots of some involuntary, uncommanded response to vibrations, which is deemed responsible for adverse aeroelastic rotorcraft-pilot couplings, thus bridging the gap between PIO and PAO in a single detailed model.
