2021年2月11日 · The Ram Air Turbine (RAT) is an emergency electrical backup device on the Airbus A380. In the event of a loss of all engines, or serious electrical problem, the RAT is used to supply essential systems with electrical power.

2025年3月2日 · The Emergency Electrical Panel is used to control the emergency electrical systems of the aircraft. The RAT is stowed, and the emergency generator does not supply the emergency network. In the event that all AC busbars are lost, the RAT automatically extends, and the emergency generator electrically-supplies the emergency network.

2021年6月21日 · 目前世界上最大的客机A380同样拥有世界上最大的冲压空气涡轮――直径为1.63米，堪比轻型飞机主发动机螺旋桨，是一只名副其实的“大老鼠”。 综合考虑不同机型供电性能、重量尺寸等因素，RAT平时收在飞机机身内侧、机翼内部乃至襟翼滑轨整流罩等部位中。 图1 A300-600飞机RAT系统. 图2 A380飞机RAT位置. 图3 A380飞机弹出RAT. RAT的前世今生？ 早在一百年前欧洲，俄制S-22飞机上，为了能够让乘客有电可用，提高乘坐体验，设计师开创性的 …

冲压空气涡轮（RAT Ram Air Turbine）是为飞机在失去主动力和辅助动力时进行应急迫降而设计的，以提高飞机的生存性。 该系统利用飞机的动能工作，在特定情况下，从飞机上应急放下一个螺旋桨，利用急速的空气来流冲击螺旋桨，其高速的旋转运动带动与之相连的电动机和液压泵，产生必要的应急能源，用于重启发动机，保证飞机操作系统、液压系统和电子设备的应急功能供电。 RAT系统需布置在非气密舱，为了得到较好的气动力载荷和释放角度，大型民用飞机的RAT系 …

2020年10月12日 · RATs on commercial aircraft (for example, Airbus A380 has the largest propeller with a diameter of 5.25 feet (1.63 m)) are much larger than others. The RAT (generally average diameter is approximately 2.6 feet (80 cm)) found in passenger aircraft is slightly smaller.

2004年9月27日 · Life saver: A Hamilton Sundstrand ram air turbine (RAT), designed for the Airbus 380, gets ready for testing at the Rockford, IL wind tunnel. A new positioning system, featuring vertical, ball-bushing slides on either side of the mounting fixture, allows operators to easily move the heavy unit into the center of the air stream.

A380配备有现代客机中最大的冲压空气涡轮，直径达1.63米，安装在左侧机翼下方作动筒，靠近机身的位置。 民用客机上的冲压空气涡轮通常有5到70千瓦不等的输出功率。

2009年12月29日 · The A380 RAT is the largest ever built and features a 64-inch diameter propeller that is deployed into the air stream from the wing fairing to power its 70 kVA air-cooled generator. If AC 1, AC 2, AC 3, and AC 4 busbars are lost in flight, the Ram Air Turbine (RAT) will automatically extend and mechanically drive the emergency generator.

几乎所有的现代民航客机都配备了RAT，波音全机型的RAT都装在靠近右侧主起落架的一个小舱里，而空客的大部分飞机 (A330, A340, A380)则将RAT置于一个后缘襟翼滑轨的整流罩内，这就是为什么这些机型会有一根整流罩两边是不对称的。

Ram Air Turbine (RAT) is a small air turbine that works as a small auxiliary propeller in the aircraft. It connects to an aircraft’s hydraulic pump or electrical generator to use as an emergency power source. So, in case of emergency, Ram Air Turbine comes into action.
