An electric linear actuator is disposed to pitch a blade of a hingeless, swashplateless rotor in rotary motion. This actuator can be equipped with an electric motor advantageously made fault tolerant by winding the motor for at least 4, 5, 6, 8, or even 12 phases. Rotational motion of ...
A blade actuation system comprises at least one motor coupled to a rotor blade for changing the pitch angle of the rotor blade. The motor is configured to wirelessly communicate wit

Multiple blade assemblies are installed to a part top of rotor-support-foundation system or lower part system. Multiple individually controllable actuators are coupled to each multiple blade assemblies. Each of multiple actuators are configured to the blade assembly of control connection around pitch ...

First, a ...
The parameter effect on swashplateless rotor control was discovered through the analyses, and the basic law of its design was obtained.Tang, LinkaiChang, MinHuang, YapingZu, SiliangBai, JunqiangInternational Journal of Micro Air Vehicles
A solution with customized passive spring-damping structures on a unique underactuated swashplateless rotor of a tiltrotor bicopter platform is presented. The implementation of this structure effectively reduces the self-coherent vibration in flights. As a result, a higher level of contro...
stabilityThis study presents the design, dynamic model, and dynamics research of a new cyclic pitch control strategy in motor-driven rotorcraft. In this strategy, the control response and flapping feature of conventional rotor systems can be obtained by imposing (1) a lag-pitch coupling on rotor...
