Helicopter Swashplate Mechanism

Application ID: 14647


This model illustrates the operation of a swashplate mechanism used in helicopters to translate the input of helicopter flight control into the motion of the rotor blades, and hence controls the orientation of the rotor blades.

In this model, the rotor blades are modeled as either rigid bodies or flexible bodies in two different cases. All other components are assumed to be rigid bodies. Stress and deformation in the flexible rotor blades caused by the rotation and applied dynamic lift force are analyzed. An eigenfrequency analysis, where the mode shapes corresponding to the bending and torsion of the rotor blades are found, is also performed.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
