Airport fire engines are fire vehicles that are designed to prevent and suppress aircraft fires, and provide timely rescue to occupants on board, and can fire extinguishing agents while the vehicle is in motion. Because of its work characteristics and the particularities of the environment, airport fire engines have higher performance requirements than ordinary fire engines. 1. Classification of airport fire engines According to the needs of airport fire fighting tactics, airport fire trucks are divided into: 1.1 Rapid Transfer Vehicle (RIV) It is also called a head car. Its extinguishing ability is small, but its speed is particularly high. The engine does not need to be warmed up. The temperature is above 7°C. The full-load driving speed is greater than 80km/h within 0 to 25s. Its role is to put fire on the crashed aircraft before the main foam vehicle reaches the plane where it crashed. It tries to control the fire and prevent the fire from spreading. 1.2 Main Foam Car (GTLF) Also known as the main vehicle, it has a large capacity for fire extinguishing, strong operational adaptability, and complete equipment and equipment. It is the main fire-fighting and rescue vehicle in the event of a plane crash at the airport. When the main vehicle is fully loaded, it can accelerate to 80km/h in 0-40s and the maximum speed is 100km/h or more. 2 Basic performance requirements for airport fire engines According to the statistics of the International Civil Aviation Organization (ICAO), 91% of plane crashes occurred when the plane took off or landed, that is, most of them occurred in an area 600m along both sides of the entire runway center line and on alternate runways, of which 71% were damaged due to fire. burn. Since most of the fuels burned when the aircraft is on fire are fuel, polymer materials and light metals, a large amount of toxic gases and smoke will be generated. After the fire, the crew can escape very quickly, so the airport fire engines must arrive in the shortest possible time. The location of the accident made it possible for the fire to be controlled in a timely manner during the escape period and help the crew to evacuate. ICAO clearly stipulates that the response time of any part of an airport fire truck arriving at an airport landing area should not exceed three minutes, preferably not more than two minutes. At present, there are no national standards for the performance requirements of airport fire engines in China. In order to meet the requirements of the standard MH7002-94 "Civil Aviation Transportation Airport Fire Station Equipment Equip", and effectively carry out firefighting and rescue, airport fire vehicles must meet the following basic performance requirements: 2.1 Chassis The chassis selected for the airport fire truck must ensure that it arrives at the crash site within the required response time. Although the airport runway area is flat, there are usually some obstacles, such as ditch, mud, etc. The airport fire trucks must cross these obstacles to reach all the possible crash sites belonging to the airport fire protection area. 2.1.1 Strong off-road performance must be all-wheel drive. The chassis must have sufficient strength and rigidity. The minimum ground clearance and approach angle and departure angle should meet the requirements. 2.1.2 High specific power (15 or more), superior power performance, ie, good acceleration performance and maximum speed. 2.1.3 The transmission system should use automatic transmission as far as possible, driving and operating a high degree of automation, and should be sensitive, convenient and reliable. 2.1.4 Good stability and low center of gravity, ie good lateral stability when driving off-road, generally requiring the vehicle to drive on a side slope of 20% (about 10?) and still have good operational stability . 2.1.5 The braking system must be a dual independent system. When the main braking system fails, another independent system can also act on the brake to ensure the safety and reliability of the braking system. The main brake should be able to stop the full vehicle on a 50% slope. 2.1.6 In-vehicle noise must be controlled within 85 decibels when the vehicle is in motion. 2.1.7 The vehicle maintenance and repair are close to the ground. 2.2 Fire Protection System 2.2.1 Large capacity, multi-functionality, high performance, and high reliability. The fire extinguishing agent has a large load, a large flow rate of the water pump, high extinguishing efficiency, and reliable system work. 2.2.2 The fire monitor is installed above the foremost end of the cab or vehicle and is rotatable 200, with an elevation angle greater than 45 and a depression angle greater than 15. The fire monitor has a large flow and can be adjusted at any time according to the fire extinguishing needs, with a long range. 2.2.3 The reaction speed is fast and the system can be put into operation at the fastest speed. 2.2.4 The control system has a high degree of automation, easy operation, safety, reliability, and responsiveness. Usually, an electro-pneumatic or electro-hydraulic power control device is used, and a spare manpower control device is also provided to prepare the power system for failure. use. 2.2.5 The use of light signals and instrumentation, instrument display, identification instructions, so that firefighters accurately obtain information on the status of the equipment at any time. 2.2.6 The manoeuvring device shall be arranged within the reach of the firefighters within reach and within reach, and a firefighter may control the fire fighting device controls. 2.2.7 Self-protecting sprinklers are installed on the front and the sides of the cab to protect the body and wheels. 2.2.8 Corrosion-resistant materials shall be used for fire-fighting pipelines and valves. 2.3 Others Airport fire trucks should also have good fire extinguishing maneuverability and certain rescue capabilities, that is, they should not only have the ability to inject fire extinguishing agents while driving, but also have the ability to rescue occupants and aircraft when the fire is controlled or extinguished. Therefore, fire engines should have seats for firefighters engaged in rescue work, and equipped with the necessary rescue equipment and safety equipment. The world-famous fire engine manufacturer currently is OSHKOSH CORPORATION’s Aircraft Rescue and Fire Fighting (“ARFFâ€) series.
