Helicopter air separation type emergency flight data recording system

Abstract

The invention discloses a helicopter air separation type emergency flight data recording system. The system comprises an emergency state analysis system, an ejection system and a buffer/floating system, the emergency state analysis system is used for judging whether a helicopter is in an emergency state or not and controlling the ejection system to be started when the helicopter is in the emergency state; the ejection system is used for ejecting the buffering/floating system out of the helicopter; the buffering/floating system comprises a radio transceiver, an electromechanical module and an air bag wrapping the electromechanical module. The electromechanical module comprises a flight data recorder and a gas generator, and the gas generator generates gas for inflating the air bag under thecontrol of the flight data recorder; and the radio transceiver is electrically connected with the flight data recorder and broadcasts a positioning signal. The helicopter air separation type emergency flight data recording system has the advantages that the unmanned aerial vehicle is intelligently and quickly separated from an airplane, high-altitude falling resistance is high, the system can float on the water surface after falling into water, and search and rescue are easy.

Description

Technical field [0001] The invention relates to the technical field of helicopter emergency, in particular to a helicopter air separated emergency flight data recording system. Background technique [0002] With the development of the civil aviation industry at home and abroad, helicopter crashes due to mechanical failures and other reasons are increasing. At present, in order to record the process of accidents, investigate the causes of accidents, and improve aviation safety, higher requirements are placed on flight data recorders (FDR). The traditional FDR is fixed inside the helicopter. When the helicopter crashes, the traditional FDR relies on its own shock-resistant structure to protect the internal data storage equipment. After the helicopter crashes, the traditional FDR relies on the waterproof structure to protect the internal data storage equipment. Search and rescue team positioning. [0003] However, the ceiling for civil helicopters is generally between 2000 and 4000 ...

AI Technical Summary

Problems solved by technology

[0003] However, the ceiling of civil helicopters is generally 2,000 to 4,000 meters, and the ceiling of military helicopters can reach 6,000 meters. If the helicopter has a mechanical failure (engine shutdown, etc.) at high altitude, it will fall at a relatively high speed. At this time, the impact resistance of traditional FDR The structure will also be damaged to varying degrees. If the helicopter crashes into the sea, its wreckage may sink into the deep sea. According to the practice of maritime air disaster rescue, traditional FDR has problems such as difficult retrieval in deep sea, underwater signal interference, and limited battery life. Salvage costs soar
