Abstract
An electromagnetic inertial actuator includes a support base and a parallel arrangement of a first flexure part, a voice coil motor part, and a second flexure part. The parallel arrangement is cantilevered from the support base.
Claims32
An electromagnetic inertial actuator, comprising:
- a support base;
- and
- a parallel arrangement of a first flexure part, a voice coil motor part, and a second flexure part, the parallel arrangement being cantilevered from the support base.
An aircraft, said aircraft having an aircraft structure and a plurality of troublesome structure vibrations, said aircraft including an electromagnetic inertial actuator support base, said electromagnetic inertial actuator support base being physically grounded to said aircraft structure, said aircraft comprising:
- an electromagnetic inertial actuator parallel arrangement of a first flexure part, a voice coil motor part, and a second flexure part, the parallel arrangement being cantilevered from the electromagnetic inertial actuator support base.
A method for controlling troublesome aircraft vibrations of an aircraft, said method including:
- providing an electromagnetic inertial actuator, said electromagnetic inertial actuator including a support base and a parallel arrangement of a first flexure part, a voice coil motor part, and a second flexure part, the parallel arrangement being cantilevered from the support base;
- physically grounding said electromagnetic inertial actuator support base to an aircraft structure of said aircraft;
- and
- electromagnetically driving said electromagnetic inertial actuator wherein said parallel arrangement traces an arc relative to said support base.
A method of making an electromagnetic inertial actuator, comprising:
- proving a support base;
- providing a coil part;
- physically grounding said coil part with said support base;
- providing a parallel arrangement of at least a first flexure part, and a voice coil motor part;
- and
- cantilevering said parallel arrangement from the support base.
