国内外直升机水下逃生训练的简述Brief introduction of underwater escape training for helicopters at home and abroad
In 2017, Reese Technology introduced huet simulator to CNOOC to meet the official requirements of optio.【China National Offshore Oil Corp. 中国海洋石油总公司】
Helicopter underwater escape training is to train helicopter pilots and flight attendants in the rapid response ability of helicopter drivers and flight attendants when helicopters fall into the water because of accidents, so that they can correctly judge the escape route, adopt correct escape procedures and methods, and improve the survival probability of safety training.
For 97 times in the marine helicopter crashes abroad from 2000 to 2012, a total of 486 people were involved, 159 of whom died, with a survival rate of 68%. In the helicopter crash incident, the average response time from the flight attendant to the crash is about 15 seconds, and 70% of the helicopters will capsize within 10 seconds after falling into the water, so escaping quickly from the helicopter cabin is a necessary skill to survive. Facts have proved that underwater helicopter escape training can effectively save lives. According to statistics, the mortality rate of personnel trained by huet in helicopter crash accidents is about 8%. The mortality rate for those who have not received huet training has risen to 20 per cent. At present, most European and American countries force flight attendants to accept the helicopter underwater escape training course certified by the authority before taking on duty and obtain the corresponding qualification.
国际直升机水下逃生训练International Helicopter Underwater Escape Training
The underwater escape training of helicopters can be divided into civilian and military according to the use of helicopters. The following is an introduction to the underwater escape training of helicopters (with EBS Emergency Breath System) certified by optio at the Irish Maritime Institute.
坠机准备训练Crash preparation training

In practice, students have to prepare on land, and everyone should receive the attention of helicopter emergency landing. At the beginning, wear all helicopter lifejackets and EBS devices (non-analog devices), and perform the following four key steps:
Diving adaptation training, students dress down a fixed rod diving about 2 to 3 meters, hold breath and wear EBS training, so that the instructor can observe the underwater situation of the students, especially for those who cannot swim, the students float according to the instructions of the teacher.
In aircraft training, the participants will learn to wear and release the helicopter safety belt. This skill is very good to learn;Learn to identify the nearest escape exit(window)and observe the overall situation of the engine room.
Support posture training, maintain the correct posture and escape position and form habits during the crash, which can reduce the helicopter falling to the surface of the water or land gravity impact and flip impact again.
For underwater escape posture training, students should put one hand on the releasing buckle of the safe belt and the other hand should be pressed on the nearest exit reference point. Avoid the crew losing their way after the helicopter is subverted.
This training is to simulate the helicopter landing. Personnel find the lifeboat and release. After the underwater escape, personnel evacuate to the process of the life raft. In this process, I will learn how to take a warm posture in the water, organize team cooperation to be saved and work as a team to carry out water movement by other standard operations. In addition, the most important thing is that the trainer and the students repeatedly emphasize that they should always be optimistic and positive, that the team should have a leader, that all actions should be directed by the leader, and that after discovering the lifeboat, they should work together to pedal the raft in order. After the raft there are a lot of details of the training content, here is not much description.

EBS is divided into two types: one with an airbag, and breathing again by exhaling itself, which can last for about 2 minutes; the other with a small cylinder can last about 3 minutes to breathe. Learn to wear and adapt to breathing. Biting the mouth under the water must bite tight, otherwise it will choke water.
模拟直升机部分倾覆水中逃生训练Escape training in partially capsized Water of simulated helicopter
In the effective simulation of helicopter capsizing train, students are familiar with the process of the environment, building confidence in dealing with accidents by step and mastering escape skills.
Students do not equip the EBS, simulator without windows and escape from the half-capsized simulator according to the specified escape port.
Students equip with EBS, simulator without installing windows and escape from the half-capsized simulator according to the specified escape port.
Students equip with EBS, simulator with installing windows and escape from the half-capsized simulator according to the specified escape port. In this step, students learn how to release windows or doors quickly.
模拟直升机全部倾覆逃生训练Simulation helicopter overturning escape training
After the helicopter falls into the water due to the deviation of the center of gravity, it will overturn after entering the water. Generally, this process is only about 10 seconds. After the helicopter flipping state is relatively stable, it is the best time to escape, and the process is also trained in three steps.
Students do not install ebs, simulator without windows and simulator flip, according to the specified escape port to escape from the capsized simulator.
Students equipped with EBS, simulator without installing windows and simulator flip, according to the specified escape port to escape from the capsized simulator.
Students equip with EBS, simulator with installing window and simulator flip, according to the specified escape port to escape from the capsized simulator. Then, the student will inflate and release the lifejacket and swim to the rescue point of the sea helicopter simulated by an aviation winch.
军事训练的浅谈A brief talk on military training
国外军事训练模拟器及训练场景The Simulator of Foreign Military Training And Training Scene
Compared with civil aircraft flight attendants, military personnel need customized simulation equipment, more subject training, sufficient training time and higher related skills requirements. The simulation equipment must be the same as the internal mechanism of the actual model aircraft, made in the proportion of 1:1, such as the size and position of doors and windows, the release mode, the placement point and size of the military equipment inside the helicopter should be restored strictly according to the actual model and so on. Other supporting equipment, such as the relevant cranes, need to have the manned certification of the third party authority in order to meet the safety requirements of simulated rescue operations and rapid drop operations in high-intensity military training courses, and the final training effect of military personnel is also more strictly evaluated.
At present, all relevant military personnel, globally， either flight attendants or driving, must at first， participate in different specifications of huet training in order to improve the survival rate of accidents.
I hope it can give some inspiration to the relevant personnel in China. This kind of underwater escape training is necessary for all flight operators and flight attendants, including on fixed-wing aircraft. In the event of failure to eject and escape in time, pilots should also have the ability to escape and save themselves at the time of forced landing. Even participating in the most basic huet training can improve survival, military applications will be more significant, saving more lives!
To sum up, helicopter underwater escape training, like any other safety training, aims to enable trainers to master the skills they must master when dealing with accidents through the most scientific and adequate training means, so as to achieve the best effect of preventing accidents.
If you want to do anything, you must make it easy.. The shorter the process of "altruism", the more "good things" can be done as soon as possible. The author believes that the domestic huet related fields are still in its infancy, and the major training and safety training institutions in the world, simulation equipment manufacturers and OPITI and other standard certification organizations have more than 25 years of rich training, certification and simulation equipment manufacturing and design experience. This is the shortage of software and hardware resources in our country at present. Therefore, in the training methods and organizations, equipment manufacturing and use, the domestic should make full use of and draw lessons from the existing international resources as a "sharp weapon" to improve and meet the needs of China's huet and even all the safety training fields.
At present, China has no legislation to force flight attendants to receive huet training and be qualified to take up posts, and even the entire domestic security training industry is still in a state of chaos in management, which is quite different from the international level. It is hoped that the relevant laws and regulations can be issued as soon as possible for not only the safety of training cause in our country, but also more lives saving in the accident.
