Does a helicopter have a black box? Please help!

The "black box" is one of the specialized electronic recording devices for airplanes, and its real name is aviation flight recorder. It is equipped with a flight data recorder and cabin sound recorder, the aircraft mechanical parts and electronic instrumentation are equipped with sensors connected to it, which is like the human body parts of the nerves and the brain connected to the same. It can record the relevant technical parameters and cockpit sound half an hour before the airplane stops working or crashes, and re-release the recorded parameters when needed for flight experiment and accident analysis. The black box has strong resistance to fire, pressure, shock and vibration, seawater (or kerosene) immersion, magnetic interference and other capabilities, even if the aircraft has been completely destroyed, the data recorded in the black box can also be well preserved. All the causes of air crashes in the world are found out through the black box, so it becomes the witness of the accident, and also becomes the "lesson learned", to avoid the same accident from happening, and to take better safety measures. I'm sorry, but I'm not sure if I'm going to be able to do this. Answer time 2008-06-01 17:04 Prosecution More than 20 years ago, a military airplane exploded in the sky over Norway, crashing and killing the pilot. The Norwegian authorities rushed to the scene of the accident and recognized from the wreckage of the plane and the body of the pilot that it was a military reconnaissance plane belonging to a major country. Norway protested to a major power, which denied it. Later, Norway found the black box on the plane and analyzed the data recorded from the black box to reveal the truth. A major country had to admit its mistake in the face of ironclad evidence. What in the world is a black box? In fact, "black box" is a common name, its real name is very common: flight data recorder. It is a kind of airplane flight situation will be stored down the instrument, when the future need to understand the flight situation, you can replay the equipment to put them out. In a box with a magnetic recording device, it can record in real time what the pilot says, the pilot's off-board communications and flight data. Generally, it can retain all kinds of information 30 minutes before an airplane accident. This makes it convenient to analyze the failure afterwards. The earliest use of black box is military aircraft. 1908, the United States occurred the first military aircraft accident. Later, as flight accidents increased, there was an urgent need for an instrument to study the causes of accidents. In World War II, flight recorders were officially used on military airplanes. After the war, it began to be used on civilian airplanes. In the early days, the recording method was backward, using mechanical recording method, recorded on photographic paper. It was only after the invention of magnetic recording that it became convenient and reliable. Why is the flight recorder called "black box"? Originally, in order to ensure that this equipment is not destroyed in the aircraft accident, specially made for it a strong box. This box is resistant to high temperatures (600 degrees Celsius to 800 degrees Celsius), high pressure (can withstand 1 ton of pressure), not afraid of corrosion, made of metal. In fact, this metal made of "black box" is not black. "Black box" is not based on its own color named, but people regard it as an ominous thing of the crash, so named "black box".
