Question:
are looking for a general plane crash black box, which records the contents of the main,
Answer:
air after the accident, the aircraft often disintegration, and even the fire burned, the pilot and other martyrs. The cause of the accident investigation will have much difficulty, but one thing can provide evidence to the investigating officers to help them understand the truth of the incident, which is known as the air crash, of the black box.
black box mounted on the tail part of the most secure, able to withstand 1100 degrees C flame grill for 30 minutes, can withstand 2 tons of heavy objects, squeezing five minutes, in gasoline, immersion in seawater for several months, that is, in many adverse conditions can be safe. Aircraft fitted with black box flight data recorder and cockpit voice recorder can be made to provide an instant crash and the crash of the flight for some time before and after situation, the work of aircraft equipment and the crew all kinds of dialogue. Air crash black box found at the scene, you can basically find a plane crash some real reason.
flight situation as
flight data recorders, commonly known as black box, divided into the flight data recorder (Flight Data Recorder, FDR) and cockpit recording device (Cockpit Voice Recorder, CVR) in two parts, the location of the installation of the most commonly in the air when preserved the integrity of the tail. Flight data recorder records the contents, including air speed, altitude, heading, engine thrust data, information on pitch and roll, vertical acceleration data and information on many parameters, according to the U.S. Federal Aviation Administration flight data recorders on the minimum requirements, must include pressure altitude, airspeed, magnetic heading, acceleration and time, such as 5, in addition to the five, the United States to ask the Civil Aviation Authority of the other pitch attitude, roll attitude, engine power and flap position; cockpit recording device, also known as call Recorder can record phone conversations to drive with the control tower, cockpit voice (warning devices, engines), record time of about two hours, were recorded after rewind automatically recorded starting from scratch, if the crash occurred, two hours before integrity will be preserved and continue to signal until the power so far. Its external steel material for titanium metal, length 50 cm, width 20 cm, 15 cm high. In order to be able to survive under the strong impact, the black box must pass the test of fire earthquake, in accordance with the provisions of the U.S. Civil Aviation Authority, the black box must be able to put up with the 1090 ℃ in combustion flames within 30 minutes, and can withstand up to three meters of the 230 kilograms of iron hit, which is equivalent to 100G of the impact of up to 11 seconds, while the U.S. Federal Aviation Administration of the provisions of 100G of the impact of 15 seconds, as most of the Earths surface is covered by water, so the black box must also be capable of sustaining 20,000 feet of water pressure. External installation of the black box of the buzzer cylindrical, as long as I get the black box of water, the water will short-circuit to circuit, the frequency of 37.5kHz buzzer will issue the calls continued for 30 days. In addition, in order to prevent magnetic memory recorder with current or magnetic field were damaged, anti-black box with the outside world but also current, magnetic field protection. a solid black box
case for the rectangular, about four or five large brick base with the general. Internal net is more electrical devices, in essence, is a transceiver. In the course of flight, it will be collected by the sensor board to receive timely information and then automatically convert the digital signal for the corresponding record; when the crash when the black box relying on the emergency locator transmitter automatically to all launch a specific frequency (eg 37.5 kHz), a similar heart rate as regular radio signals, their own position in which to search to find those who wave back. In 1974, a Boeing 707 crashed into the water depth of 3,000 meters of the sea, is on this radio positioning signal to find the black box. Because of the limited capacity of the battery box inside, the positioning drive letter is usually only one or two months of continuous work. If salvage is not timely, the black box will disappear.
each aircraft, the black box is usually two, their name is called, respectively, The former record of aircraft flight data, including flight attitude, flight path (track), flight speed, acceleration, latitude and longitude, direction and role in a variety of external forces on the aircraft, such as resistance, lift, thrust, etc., a total of about 200 wide variety of data, be able to retain more than 20 hours of flight parameters. Over this time, data logger automatically吐故纳新, the old data by new data coverage. The main cabin voice recorder records the crew and ground staff of the call, the dialogue between the crew, as well as inside the cockpit of a variety of audio (including the operation of aircraft engine sound) and so on. Its working principle similar to an ordinary tape recorder, tape to run non-stop wash cycle was recorded in the old and new is always recorded in the last half an hour left of the various voices
Answer:
black box is to describe the appearance, inside equipped with special apparatus, designed to record the aircrafts flight, unless regular maintenance, or never opened. Such a box in a total of two aircraft. One of them is the wireless phone
recorder, to record the dialogue between the crew. But its a long recording length is only 30 minutes, 30 minutes after the re-recorded from scratch. Another black box flight data recorders that can record more than 30 kinds of data, the data within 25 hours the situation is a lot of equipment capable.
as black boxes is to provide a major source of clues to the crash, there must be a perfect protection; On average, the black box can withstand 1000 degrees Celsius for more than 30 minutes of high temperature as long as three meters deep in the water, safe water 30 days.2006-05-20
问题:
一般飞机失事都要找黑匣子,里面主要记录什么内容,
回答:
空难事故发生后，飞机往往解体，甚至被烈火烧毁，飞行员等殉难。调查事故原因有很大困难，但有一样东西可以给调查人员提供证据，帮助他们了解事故的真相，这就是被称为空难"见证人"的黑匣子。
黑匣子装在机尾zaq部位，能经受1100摄氏度火焰烧烤30分钟，能承受2吨重物体挤压5分钟，能在汽油、海水中浸泡几个月，即在许多恶劣条件下能安然无恙。飞机上黑匣子装有飞行数据记录仪和座舱话音记录仪，可向人们提供飞机失事瞬间及失事前后一段时间的飞行状况，机上设备工作情况及机上人员各种对话。空难现场找到黑匣子，就能基本找到空难事故的某些真实原因。
被当作飞机飞行状况“见证人”的黑匣子，其实并非是黑的，而是常呈橙红色。因为它能帮助破解飞行事故（尤其是飞机在失事瞬间和失事前一段时间的飞行状况）的秘密，因此叫“黑匣子”。
飞航资料记录器，俗称黑匣子，主要分为飞行资料记录器（Flight Data Recorder，FDR）与驾驶舱录音器（Cockpit Voice Recorder，CVR）两个部分，装设的位置在空难时最常被完整保留下来的机尾上。飞行资料记录器记录的内容包括空中飞行速度、高度、航向、发动机推力资料，俯仰与滚动资料，纵向加速度资料及许多参数资料，根据美国lb航空总署对飞行资料记录器的{zd1}要求，必须包括压力高度、空速、磁航向、加速度及经过时间等 5 项，除了上述五项，美国民航局另外再要求俯仰姿态、滚转姿态、发动机动力及襟翼的位置；驾驶舱录音器又称通话记录器，可录下驾驶与塔台通话内容、驾驶舱声音(警告器、引擎)，记录的时间约二小时，录完后，会自动倒带从头录起，若发生空难，之前的两个小时会被完整保留，并持续发出讯号，直到断电为止。其外部的材质为钛钢金属，长50厘米、宽20厘米，高15厘米。为了能在强力撞击下保存下来，黑匣子必须通过防火防震的考验，根据美国民航局的规定，黑匣子必须能忍受在1090℃的火焰中燃烧30分钟，并能承受3米重达230公斤之铁块击中，相当于100G之撞击达 11秒，而美国lb航空总署的规定为100G 之撞击达 15 秒，由于地球表面大部分是由水所覆盖，因此黑匣子也必须能承受2万英尺的水压。黑匣子的外部加装圆筒型的蜂鸣器，只要黑匣子一碰到水，水分会使其线路发生短路，蜂鸣器将会发出37.5kHz频率的鸣叫持续30天。除此之外，为了防止记录器内磁性记忆遭到电流或磁场破坏，黑匣子也要具备抗外界电流、磁场的防护能力。
黑匣子外壳坚实，为长方体，约等于四、五块砖头垒在一起一般大。内部净是些电气器件，实质上是一台收发信机。在飞机飞行过程中，它能将机内传感器所收集到的各种信息及时接收下来，并自动转换成相应的数字信号连续进行记录；当飞机失事时，依靠黑匣子的紧急定位发射机自动向四面八方发射出特定频率（例如37．5千赫），类似心跳般有规律的无线电信号，“宣告”自己所处的方位，以便搜寻者溯波寻找。1974年，一架波音707坠入水深3，000多米的海底，就是靠这种无线电定位信号找到黑匣子的。因为匣内电池容量有限，定位发信机通常只能连续工作个把月。如果打捞不及时，黑匣子就会销声匿迹。
每架飞机上，黑匣子通常有两个，它们的学名分别叫“飞行数据记录仪”和“机舱话音记录器”。前者主要记录飞机的各种飞行数据，包括飞行姿态、飞行轨迹（航迹）、飞行速度、加速度、经纬度、航向以及作用在飞机上的各种外力，如阻力、升力、推力等，共约200多种数据，可保留20多小时的飞行参数。超过这个时间，数据记录仪就自动吐故纳新，旧数据被新数据覆盖。机舱话音记录器主要记录机组人员和地面人员的通话、机组人员之间的对话以及驾驶舱内出现的各种音响（包括飞机发动机的运转声音）等。它的工作原理类似普通磁带录音机，磁带周而复始运行不停地洗旧录新，总是录留下{zh1}半小时的各种声音
回答:
黑盒子是外观的形容，里头装有特殊仪器，专门用來记录飞机的飞行情況，除非进行定期检修，否则从来不会打开。这样的盒子在飞机上一共有两个。
其中一个是无线电话记录器，用来记录机组人员间的对话。但是它的录音长長度只有30分钟，30分钟过后，再从头录起。另一个黑盒子是飞行数据记录器，它能记录三十多种数据，25小时內的数据状況，是个本事很大的器械。
因为黑盒子是提供空难线索的主要来源，必須有完善的保护；平均来说，黑盒子能承受摄氏一千度以上高温三十分钟之久，在三米深的水里，安全防水三十天。2006-05-20
