DUAL-CONCENTRIC CONTROL VALVE WITH DIRECT DRIVE CONTROL AND FAILED MOTOR PROTECTION

The present disclosure relates to a dual-concentric control valve with direct drive control and failed motor protection. Systems and methods include providing an aircraft with a direct drive dual-concentric valve (D3V) having a body, an outer secondary spool coaxially located within a bore of the body and linearly displaceable relative to the body, an inner primary spool coaxially located within abore of the secondary spool and linearly displaceable relative to the secondary spool and the body, and multiple motor assemblies coupled to the primary spool that provide selective displacement of the primary spool or the secondary spool. Each motor assembly includes a clutching mechanism that selectively couples a motor of the motor assembly to and from the primary spool. 本公开内容涉及具有直接驱动控制和故障马达保护的双同心控制阀。系统和方法包括提供具有直接驱动式双同心阀D3V的飞行器，直接驱动式双同心阀D3V具有：本体；外部次级阀芯，其同轴地定位在本体的孔内并且能够相对于本体线性地移位；内部主阀芯，其同轴地定位在次级阀芯的孔内并且能够相对于次级阀芯和本体线性地移位；以及多个马达组件，其耦接至主阀芯，提供主阀芯或次级阀芯的选择性移位。每个马达组件包括离合机构，离合机构将马达组件的马达选择性地耦接至主阀芯以及从主阀芯选择性地耦接马达。
