The aeroelastic analysis of a helicopter rotor blade with the controlled oscillating trailing edge flap is presented by building an aeroelastic model of the new concept rotor blade.

通过建立带受控振荡附翼的新概念旋翼气动弹性分析模型，研究了采用受控振荡附翼的直升机旋翼气动弹性特性及其在降低旋翼振动载荷方面的有效性。

A section of (wing trailing-edge) flap detached during flight probably due to material fatigue.

一段襟翼在飞行中掉落可能因材料疲乏。

However, there are always a few that prefer to skate too close to the edge, flap their wings, and create more of a market nuisance than anything else.

The blades are vibrated from side to side, as well as up and down (edge fatigue and flap fatigue) for millions of cycles, simulating twenty years of activity in the real world.

On the bottom edge is a trick flap that's both a micro-USB socket and a USB Type A plug depending on how it's positioned -- the micro-SIM slot is cleverly hidden behind it.
