- General specification for helicopter blade lead - lag damper
直升机桨叶摆振阻尼器通用规范 - Within this analytical model , the factors as unsteady aerodynamic and blade flap / lead - lag coupled motion are both considered
旋翼机体耦合动力学模型考虑了非定常空气动力和桨叶挥舞摆振运动耦合。 - Among others , one method to solve this problem is to install lead - lag dampers . the conventional configuration for installing dampers is to put them between blades and hub . in 1990s , eurocopter began to use the inter - blade dampers in ec155 which means to put every damper between two adjacent blades
传统的减摆器布置是桨叶-桨毂式;上个世纪90年代,欧直公司开始在ec155上使用叶间减摆器,减摆器不是布置在桨叶和桨毂之间,而是布置在相邻两片桨叶之间。 - This model is formulated as a non - linear state - space representation of helicopter flight dynamics , incorporating with blade element unsteady aerodynamics , a finite state dynamic inflow wake model , and flapping / lead - lag blade dynamic model . the formulation of the coupled rotor and fuselage equations enables the use of common solution techniques for trim and linearization in arbitrary steady flight condition as well as control response calculations
本项研究针对新机研制过程必须解决的品质评定、飞控系统设计等问题，按照ads - 33军用品质规范的要求，建立了一个较完整的直升机非线性的、具有状态空间表达形式的飞行动力学模型，进行了模型验证工作，并以某样例直升机为例，计算了ads - 33品质规范（ 3
