起落架

STRUCTURE: Titanium and composites used extensively, with particular emphasis on corrosion resistance; fully articulated three-blade coaxial contrarotatmg rotors have all-composites blades with carbon fibre and glass fibre main spars, pockets (13 per blade) of Kevlar-type material, and filler similar to Nomex; blades have non-symmetrical aerofoil section; each has ground-adjustable tab; each lower blade carries adjustable vibration damper, comprising two dependent weights, on root section, with further vibration dampers in fuselage; tip light on each upper blade; blades fold manually outboard of all control mechanisms, to folded width within track of main landing gear; rotor hub is 50% titaniuin/50% steel; rotor brake standard; all-metal fuselage; composites tailcone; fixed incidence tailplane, elevators, fins and rudders have aluminium alloy structure, composites skins; fins toe inward approximately 25°; fixed leading-edge slat on each fin prevents airflow over fin stalling in crosswinds or at high yaw angles.

结构：钛和复合材料广泛使用，耐腐蚀性能与特别强调，充分阐明三叶片转子同轴contrarotatmg有碳纤维和玻璃纤维的主要棒材全复合材料桨叶，口袋（每刀片13）凯夫拉型材料，类似的Nomex纤维填料；叶片非对称机翼部分，每有地面可调选项卡，每降低叶片振动阻尼器进行调节，包括两部分依赖重根，在机身进一步减振装置；小费每个刀片上轻；刀片倍手动舷外所有控制机制，折叠宽度内的主起落架的轨道；转子中心为50％titaniuin/50％钢；转子制动标准；全金属机身，复合材料tailcone，固定发生机尾，电梯，蛙鞋和方向舵的铝合金结构，复合材料的皮肤；鳍鳍在每个脚趾向内约25 °；固定领先的板式翅片防止了侧风或气流停滞在高偏航角度。

When 'taking-off' I simply 'taxi' on three wheels until I am moving at least 5 to 10 kph, then jerk the steering wheel to the right which lifts the bike off of the landing gear wheel.

当'起飞'我只是'的士'三个轮子，直到我移动至少5至10公里，然后挺举方向盘右边的升降机自行车起飞的起落架舱。

I accomplish this with a telescopic landing gear.

本人做到这一点的伸缩起落架。

It will expose the design problem of maintainability of civil airplane to the early stage of design. This paper discusses the composing of the virtual maintenance environment, builds non-immersion virtual maintenance environment of undercarriage, and establishes a part library management system. The characteristic of maintainability models and maintainability analysis based on virtual technique is researched to give the maintainability frame model of civil airplane virtual maintainability analysis. All levels of maintenance time model and maintenance man-hour model are established. Analog-Huffman code is proposed to optimize space partition method in traditional collision detection arithmetic."Maintenance therblig"is brought into the broken down of maintenance tasks, and the new maintenance tasks broken down method is proposed. The demands of human measure, position, and equipment layout in human engineering are discussed, and the verification methods of human measure, position and equipment layout in virtual maintenance are given. Basic principle and verification procedure of maintainability virtual verification is developed primarily, and the reachablity, the visibility, and posture-comfortability are verified.

本文论述了虚拟维修环境的组成，构建了某型飞机主起落架非沉浸式虚拟维修环境，建立了维修对象的零件库管理系统；研究了基于虚拟技术的维修性模型特点及维修性分析流程，给出了基于虚拟技术的民机维修性分析框架模型，并结合传统维修性模型，建立了各级维修时间模型和维修工时模型；提出类HUFFMAN编码，结合人因工程的要求，优化了传统碰撞检测算法中的空间分割法，使之适用于柔体；在维修性分解中引入"维修动素"，给出了与CATIA、DELMIA等应用软件结合紧密的维修任务分解方法；论述了人因工程中对人体尺寸、姿势、设备布局的要求，给出了虚拟维修中人体尺寸、姿势分析、民机内设备布局的验证方法；初步制订了维修性虚拟验证的基本原则和验证程序，并结合具体实例对可达性、可视性、干涉性以及人体姿态舒适性进行了验证，较清晰、真实地反映了维修人员的维修状态。

We have a problem with the landing gear. I need toland.

起落架出现问题，收不起来我们得折回降落

The first project of the company was the two-seat open-cockpit XA-5 "Top Sergeant", which was based on the lower fuselage and undercarriage of a Sikorsky R-6 with an open rear boom and small rudder.

该公司的第一个项目是双座开座舱的XA - 5"顶警长"，这是基于较低机身和起落架西科斯基公司的R - 6以开放后的繁荣和小舵。

We'll have to hold, checking the undercarriage for a while.

我们等待，检查起落架一会儿。

Lastly, taking the group of wheel of the main undercarriage for example, illuminating compute aided validation method.

最后以主起落架机轮组的装配图为例，详细说明了计算机辅助验证方法。

I once heard of a man who fell out of a plane but then managed to grab onto the undercarriage.

我曾听说有一个人从飞机上掉下来，却刚刚握著飞机的起落架。

Bottom view shows complete undercarriage detail down to and including brake lines.

底部视图显示完整的起落架详细下来并包括刹车线。

Do you know, i need you to come back

你知道吗，我需要你回来
