基于动态冲击试验的通勤类飞机座椅符合性验证技术

Compliance Demonstration Technology for Commuter Aircraft Seat Based on Dynamic Impact Test

国产某型民用通勤类飞机为了取得欧洲航空安全局(EASA)型号合格证,机上座椅需进行设计更改并补充进行应急着陆情况下的动态要求符合性验证。通过对适航条款及相应标准的解读,研究了基于动态试验的航空座椅动态要求适航验证技术,其主要包括座椅动态性能基本要求、试验构型及工况筛选、试验规划、合格判据和试验结果分析等内容。结果表明,该型机旅客座椅满足适航规章对座椅的动态性能要求。该项旅客座椅动态性能试验的成功为型号取得EASA型号合格证奠定了良好的基础,该型飞机也即将成为第一个取得欧洲型号合格证的国产飞机。

In order to obtain the type certificate of European Aviation Safety Agency(EASA),it is necessary to change the design and carry out dynamic impact test on the passenger seat of a domestic civil commuter aircraft in the emergency conditions.Based on the interpretation of airworthiness requirements and corresponding standards,the airworthiness demonstration technology of aviation seat dynamic requirements was studied based on dynamic impact test.It mainly included the basic requirements of seat dynamic performance,selecting test configuration and condition,test planning,pass/fail criteria and test results.The results show that the passenger seat meets the dynamic impact requirement of airworthiness regulation.The success of the passenger seat dynamic impact test has laid a good foundation for the aircraft model to obtain the EASA type certificate.This type of aircraft is about to become the first domestic civil aircraft to obtain the European type certificate.
