Bell also invented the photophone, the ancestor of optical transmission systems; the audiometer, which is still used to test hearing; a device to find icebergs by listening to underwater echoes, the ancestor of SONAR; a desalinating machine for removing salt from seawater; a medical jacket that was the predecessor of the iron lung; the hydrofoil boat; and was part of a team that invented the three-wheel landing gear and wing flaps for airplanes.

贝尔还发明了光电话，光传输系统的原形；听度计，现在还在用于测试听力，通过使用这种装置收听水底回升发现冰山，是SONAR的原形；一种将盐从海水中分离的淡化海水装置；一种医用夹克，是人工呼吸机的前身；水翼艇；贝尔作为研究队伍成员之一还参与发明了飞机三轮起落架和襟翼。

The bomb bay would be located between the two nacelles, and the tricycle landing gear would also be stored in the same area.

炸弹湾将位于两国之间的发动机舱，和三轮车起落架也将被储存在同一地区。

In accordance with the foreign carrier aircraft of similar size and weight of the structure of the standard conditions to compare the situation of J -10, the estimated result is improved for carrier-based aircraft F -10 bound to a significant increase in structural weight, if it is flying by leaping jump slide deck and conventional way of blocking the landing, the F-10B of the carrier improved in structure to increase the weight of about 500 ~ 550 kg, if the front wheel traction with catapult catapult take-off, front landing gear strength and the increase in traction structure also further increased from 100 to 150 kg weight.

按照国外类似规格的舰载机的结构条件和重量标准来对比歼-10的情况，估算的结果是歼-10改进为舰载机必然要大幅度增加结构重量，如果是采用跃升甲板滑跃起飞和常规拦阻着陆的方式，歼-10B 的舰载改进型在结构重量上大约要增加500~550千克，如果采用弹射器利用前轮牵引弹射的起飞方式，前起落架强度提高和增加牵引结构还要再增加100~150千克重量。

Six lights located above the landing gear selector lever provide indication and warning for the landing gear.

六个位于起落架手柄上方的指示灯用来起落架指示及警告。

Aircraft carrier-based fighter, not even with the slide jump the catapult off the front wheel traction mode, the aircraft landing stage in the block are inevitably linked with a bow after the process, the front landing gear before the grounding process necessarily requires the structure to withstand large the impact of such a large impact load without a decentralized structure with high strength and conductivity is unbearable.

航母舰载战斗机即使采用滑跃而不是前轮牵引的弹射起飞方式，飞机在拦阻着陆阶段挂钩后都必然会有个低头的过程，前轮接地过程中前起落架必然需要在结构上承受很大的冲击，这么大的冲击载荷如果没有一个高强度的结构进行分散和传导是难以承受的。

The taxiing performance of an active control system landing gear and that of a passive system landing gear are compared.

对主动控制起落架和被动起落架的滑行性能进行了比较。

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。

Lid landing gear box body is formed with the motor gearbox. When the furnace cover needs opening , simply press the button in the control box then the furnace cover will descend at a uniform speed .For the sake of safety ,two movements institutions tops trip switch are mounted in the carburizing EAF .When the furnace cover is ascending , the lower movements institutions tops trip switch will automatically cut off the seepage carbon EAF control cabinet main circuit power supply, forcing the heating elements stop working since the power is cut off, The upper switch is used to restrict the height of the movements axis ,it can prevent the movements pumped up too high to cause theelevating screw abscisicing from the gear box.

炉盖升降机构由电机齿轮箱组成，当需要开启炉盖时，只需按下控制箱上的按组，炉盖即以均速上升下降，为了安全起见，在渗碳电炉升降机构上装设有两个行程开关，当炉盖上升时，下边的行程开关自动切断渗碳电炉控制柜主回路电源，使加热元件断电停止工作，上边的行程开关则限制升降轴升起的高度，以防升降抽升起过高，升降丝杆脱出齿轮箱。

The results show that the loads from landing gear to aircraft body are obviously reduced by using active control technology. The motion of aircraft CG and the variation of pitch angle are more stable, and the strut load and strut stroke of landing gear can be maintained in a range of static equilibrium condition.

计算结果表明，主动控制技术可明显降低起落架传给机身的载荷，隔离由地面产生的振动，使飞机重心运动和俯仰角变化更加平稳，使起落架支柱载荷和行程位移尽量保持在静态平衡状态的一定范围之内。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
