Problems solved by technology

However, due to a series of random factors such as different flight altitudes, pressure environments, and unexpected situations of different situations during the flight, various dangerous situations that have never been dealt with often occur.
China has a number of civil aviation colleges and training institutions for aircraft pilots and flight attendants, equipped with a variety of simulation training equipment, but currently there is no professional equipment that can simulate the rapid loss of confidentiality and loss of pressure in the cabin during the high-altitude flight of the aircraft. There is an urgent need to develop and manufacture such equipment to meet the needs of aircraft pilots and flight attendants in training and scientific research

Embodiment 1

[0031] What this embodiment discloses is a simulated rapid decompression cabin of a civil cabin emptying device, and the cabin body includes a cockpit 1 and a cabin 2, and a simulated front window 3 is set in front of the cockpit 1, and the simulated front window 3 is divided into left and right sides. One, corresponding to the main driver's position and the co-pilot's position respectively, the size of the window can be adjusted according to the needs of simulation training of different models. The simulated front window is set on the cabin body, and the customized flange is processed and fixed on the cabin body by welding to form a window frame. The front window negative pressure cover 4 is connected and fixed on the outside of the window frame. The front window negative pressure cover 4 is a The window frame is dimensionally matched and has steel pressure-resistant connectors of a certain thickness. The back of the front window negative pressure cover 4 is connected with th...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that, in addition to the front window variable adjustment device 9 being arranged on the simulated front window 3 of the cockpit 1, a door variable adjusting device 9 is also arranged on the hatch door of the cabin 2. Regulator 14.

[0040] Similar to the loss of confidentiality and loss of pressure that may occur in the cockpit 1, the aircraft may also cause loss of confidentiality and loss of pressure in the cabin 2 due to various reasons during flight, such as the failure of the cabin door resulting in air leakage from the cabin door or the overall failure of the cabin door. Falling off and flying out of the cabin and so on. In order to carry out adaptive training and emergency response drills to the flight attendants in the cabin 2, the simulated rapid decompression cabin of the present embodiment is provided with a simulation device for simulating cabin door loss of secrecy in the cabin 2 (as attached figu...

Embodiment 3

[0043] The difference between this embodiment and Embodiment 1 is that, in addition to the front window variable adjustment device 9 being arranged on the simulated front window 3 of the cockpit 1, the cabin door variable adjustment device 14 is arranged on the hatch of the cabin 2 In addition, the porthole variable adjustment device 16 is also configured on the porthole of the engine room 2 .

[0044] Similarly, in order to simulate the rapid decompression in the engine room caused by cracks and falling off of the portholes in the engine room 2, a simulated porthole 15 and a variable adjustment device 16 for the porthole are installed on the bulkhead of the engine room 2. The porthole negative pressure cover 17 and the porthole negative pressure pipeline 18 are connected to the negative pressure tank 6, and a porthole electric control gate valve 19 is installed on the porthole negative pressure pipeline 18, which simulates a rapid decompression in the cabin when the porthole i...

Abstract

The invention relates to a simulation rapid decompression cabin for a civil aircraft. The cabin comprises a simulation window, a variable adjusting device installed on the simulation window in a matched mode, and a negative pressure air exhaust system arranged outside the cabin and communicated with the simulation window. The variable adjusting device comprises a template matching the simulation window and a locking piece for detachably installing the template on the simulation window. The negative pressure air exhaust system comprises a negative pressure tank, a negative pressure pipeline, anelectric control gate valve and a negative pressure cover, the negative pressure tank is provided with a vacuum pump, one end of the negative pressure pipeline is connected with the negative pressuretank, the other end of the negative pressure pipeline is connected with the negative pressure cover, the negative pressure cover is arranged outside the simulation window, and the negative pressure pipeline is provided with the electric control gate valve. According to the invention, the process of simulating the leakage and voltage-losing states of the aircraft is adjustable and controllable. And a simulation platform and equipment guarantee are provided for adaptive training and emergency disposal drilling of aircraft drivers and crew members.

Description

technical field [0001] The invention relates to an aviation simulation training device, in particular to a simulated rapid decompression cabin of a civil aircraft, and belongs to the technical field of aircraft simulation training devices. Background technique [0002] With the rapid development of the country, various civil aircraft are used more and more, and China has become one of the countries with the largest number of civil aviation passenger aircraft in the world. The safety of pilots and passengers has frequently occurred due to extreme weather or aircraft failures during flight, and the flight safety of civil aviation passenger aircraft has become the most important issue in the civil air transport industry. [0003] [Case: On May 14, 2018, Sichuan Airlines flight 3U8633 was cruising in the Chengdu area, the front windshield of the right seat in the cockpit broke and fell off, and the crew made an emergency descent. The co-pilot was sucked out of the aircraft du...
