An evaluation method for emergency lifesaving performance of inflatable lifejackets used in aviation

Abstract

The invention discloses an evaluation method for the emergency lifesaving performance of an inflatable life jacket for aviation. The method comprises the following steps: according to a determined subject, carrying out life jacket packaging bag take-out time testing, life jacket packaging bag opening time testing, and life jacket wearing time testing to obtain a life jacket wearing index Idon; carrying out life jacket buoyancy force testing on the life jacket and life jacket thermal resistance testing of close contact with the body core parts to obtain an in-water lasting survival index Iwater; carrying out life jacket indicator distance testing on the life jacket to obtain an indicator rescue index Ipos; and on the basis of the Idon, the Iwater and the Ipos, acquiring an emergency rescueindex LSP of an inflatable life jacket for aviation to evaluate the emergency lifesaving performance of the inflatable life jacket for aviation. According to the invention, the emergency lifesaving performance of an inflatable life jacket for aviation is integrated into the product of the life jacket wearing index, the in-water lasting survival index, and the emergency rescue index, so that the quantitative evaluation of the emergency lifesaving performance of the life jacket is realized and consumers are guided to go shopping.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an evaluation method for the emergency lifesaving performance of an inflatable life jacket for aviation. Background technique [0002] At present, there are many types of inflatable life jackets for aviation in the market. When purchasing an inflatable life jacket for aviation, users can only judge whether to buy it based on external and less important secondary factors such as price, appearance, and material. When the aviation department judges the inflatable lifejackets for aviation, it can only measure whether the lifejackets meet the national standard GB / T 36508-2018 "Inflatable lifejackets for aviation" or the US TSO-C13 series standards through authoritative laboratories. Then a judgment is made that the criteria are met or not met, which cannot be further quantified. However, the purpose of aviation inflatable lifejackets is to save people.

[0002] At present, there are many types of inflatable life jackets for aviation on the market. When users buy inflatable life jackets for aviation, they can only judge whether to buy them based on external and less important secondary factors such as price, appearance, and material.

When the aviation department judges the inflatable lifejackets for aviation, it can only measure whether the lifejackets meet the national standard GB / T 36508-2018 "Inflatable lifejackets for aviation" or the US TSO-C13 series standards through authoritative laboratories. Then make a judgment of meeting or not meeting the standard, which cannot be further quantified

However, the purpose of aviation inflatable lifejackets is to save people. The most important characteristic of aviation inflatable lifejackets is the ability to ensure the survival of those who fall into the water in the event of a ditching accident, that is, emergency lifesaving performance. At present, there is no evaluation method for the most important emergency lifesaving performance of life jackets
