Intelligent monitoring method for airplane heavy landing

Abstract

The invention relates to an intelligent monitoring method for airplane heavy landing. The method includes the steps that firstly, according to the characteristics of an airplane, the relationship between the airplane flight parameter and the airplane structure bearing parameter is obtained through analysis, wherein the airplane flight parameter comprises the sinking speed, and the airplane structure bearing parameter comprises the airplane landing weight; secondly, the overload judgment parameters and a threshold value are determined, wherein the overload judgment parameters comprise the airplane landing design weight and the maximum landing weight; and thirdly, a landing diagnostic model is established and judges whether the airplane landing process is a landing overload process or not. By the adoption of the intelligent monitoring method for airplane heavy landing, whether the airplane landing process is a heavy landing process or not can be effectively judged, an effective early warning can be given, the manual data analysis time and the unnecessary overhaul and maintenance time are greatly shortened, the work efficiency is improved, and accuracy is high.

Description

technical field [0001] The invention belongs to the field of aircraft maintenance design, in particular to an intelligent monitoring method for heavy landing of an aircraft. Background technique [0002] Foreign countries have been involved in early warning of overloaded landings. For example, most aircraft of Boeing and Airbus have flight quality monitoring systems, which include the monitoring of heavy landings. According to the report of the FAA (Federal Aviation Administration, the full name is the Federal Aviation Administration of the United States), through the monitoring of the heavy landing event, the inspection of the heavy landing of the aircraft is reduced, the safety level is improved, and the maintenance time and cost are saved at the same time. China started relatively late in the field of overload landing warning. Although there are relevant theoretical studies, no domestically-made aircraft has truly realized overload landing monitoring. In addition to the c...

Problems solved by technology

However, the sinking speed of the aircraft is not easy to measure accurately. Usually, it is only based on the landing weight to determine whether to carry out the overload inspection, which requires a large amount of data analysis after the flight.

However, judging only by the weight of the aircraft will add a lot of additional inspection items that are not actually necessary, and consume a lot of manpower and material resources.

For example, after a key model modified aircraft in China is equipped with a new type of guided weapon, its landing weight has exceeded the design landing weight. According to the existing treatment method, overload inspection and maintenance can only be carried out after each landing. The load exceeding the structural use accounted for only a small part, which caused some unnecessary work to be carried out and took up a lot of time, resulting in the failure of its test flight and field training to be carried out on schedule
