Demonstrations of the hybrid control concept for vibration reduction on helicopters

一个独特的主动控制系统，减少振动和噪音的直升机将演示在旋转塔（或离心）试验和计算机模拟。该系统是由卡尔顿大学的两位申请者开发的，从其他控制系统中脱颖而出，因为它是第一个在每个直升机叶片上同时使用流量控制和结构控制装置的系统。因此，该概念被命名为混合控制，其主要优点是它可以在减少振动方面获得卓越的效率，并且有望成为第一个同时减少振动和噪声的系统。混合控制概念的一个关键要素是主动俯仰连杆，这是有史以来第一个可以控制叶片结构响应的设备原型。混合控制系统的独特概念以及主动螺距链接的设计已获得专利保护，并设计为在功率输出或执行器故障的情况下具有故障安全。如果该提案中概述的演示成功，它将为该产品的商业化打开大门，该产品预计将由一家加拿大分拆公司生产并提供给直升机制造商，该公司雇用约40-55人。

A unique active control system for reducing vibration and noise on helicopters will be demonstarted in whirl tower (or centrifugal) tests and computer simulations. The system was developed by the two applicants at Carleton University and stands out from other control systems by being the first one to employ both Flow Control and Structural Control devices on each helicopter blade. For this reason, the concept is named as Hybrid Control and its main benefits are that it allows to obtain superior effiociency in reducing vibration as well as promises to be the first system to reduce vibration and noise simulataneously. A key element of the Hybrid Control concept is the Active Pitch Link, which is the first ever working prototype of a device which can control the structural response of the blade. The unique concept of the Hybrid Control system as well as the design of the Active Pitch Link has been patent protected and designed to be Fail Safe in the case of power output or actuator failure. If the demonstrations outlined in this proposal are successful, it will open the door towards commercialization of the product, which is envisioned to be manufactured and supplied to helicopter manufacturers by a Canadian spin-off company emloying about 40-55 people.
