飞机起落架

Aluminum- bronze alloy bushing s are mainly used in landing gears.

铝青铜合金衬套主要用在飞机起落架部位，衬套的质量问题也会影响飞行的安全。

At shortenned zero receive, fixing of partses with consign time after, should the company expand to the service airplane of havings turnover piece(in addition to launching machine and airplane to rise and fall), but not only be limited by the product of our company 6 year ago, Collins' company of average fix a period is 23 days.

在缩短了零部件的接收、修理和交付时间后，该公司将服务扩展到飞机的所有周转件(除发动机和飞机起落架外)，而不仅限于本公司的产品。6年前，柯林斯公司的平均修理周期是23天。

The undercarriage was a tricycle arrangement, with the wide-track main units retracting inwards into the wing and the nosewheel retracting backwards (following a 90 degree rotation) into the area beneath the cockpit.

飞机起落架是一个类似三轮车布局，配制宽轨的主起落架部分可以向后缩进机翼内，前轮向后回缩（自转90度）进座舱下部的区域。

It is the pilot putt the wheel down.

那是飞行员在放下飞机起落架的声音。

It was the pilot putt the wheel down.

那是飞行员在放下飞机起落架的声音。

This thesis analyses and studies the electric powered servo load system deeper based on the load system of one minitype robot bomb undercarriage, and brings forward some effectual control methods.

本论文就是基于某小型无人飞机起落架伺服加载系统的预研项目，对电动伺服加载系统作了较深入的分析和研究，提出了一些有效的控制方法。

The mathematical model for undercarriage load simulation system of a certain airplane is established in this paper.

建立了某型飞机起落架负载模拟系统的数学模型，将起落架位置干扰量作为系统的不确定参数，设计了系统输出力矩跟踪空气动力载荷谱的非线性控制规律并进行了系统仿真。

The microstructure, strength-toughness and fatigue properties of an ultrahigh strength steel 40CrMnSiMoVA have been investigated. The so-called eta-bainite,composed of thin rareined austenite films within or between the bainitic ferrite laths was found in the steel after isothermally quenched at 300℃ for 1h.

本文研究了飞机起落架用超高强度40CrMnSiMoVA钢的显微组织、强韧性和疲劳性能，结果表明，该钢经300℃等温1h淬火可获得由贝氏体铁素体板条与条间或条内的残余奥氏体薄膜所组成的准贝民体组织。

Moreover,it establishes the foundation to the research on the aircraft taxiing characteristics.

飞机起落架系统是飞机的一个重要组成部分，在飞机

In order to study the aircraft taxiing characteristics, considering the aircraft's attitude and rotation, the aircraft landing gear system mathematical model is built including tire model, ole-pneumatic shock strut model, landing gear walking model and main wheel brake device model.

为了研究飞机地面滑跑特性，考虑到滑跑过程中飞机姿态和转动的影响，建立了飞机起落架系统的轮胎模型、空气油液缓冲模型、起落架走步模型和主机轮刹车装置模型。
