Aircraft canopy framework overhauling and monitoring using method thereof

Abstract

The invention relates to a monitoring using method for an aircraft canopy framework overhauling. The method comprises the following steps that a plurality of weak parts in a canopy framework are determined according to a static force test and a fatigue test; the fault information of the canopy framework from a similar series of aircraft in an overhaul factory and external field use scene is acquired; a canopy is checked in the overhaul factory; the damage tolerance analysis is carried out on the parts with large stress in the static force test and the fatigue test and parts which faults in theexternal field use; according to test results and a damage tolerance analysis result, the dangerous weak parts in use are determined; the check parts and a check method are determined according to the dangerous weak parts; preventive reinforcement repairing is carried out on the dangerous weak parts not meeting secondary overhaul in the damage tolerance analysis; the check parts and a check cycleare determined during monitoring using of the canopy framework; and risk assessment is carried out during monitoring using of the canopy framework, and a monitoring using conclusion is given. It canbe guaranteed that the secondary overhaul is used by the canopy framework determined by the monitoring using method, and the use cost of the parts is reduced.

Description

technical field [0001] The application belongs to the technical field of aircraft structure maintenance, and in particular relates to an overhauled aircraft canopy frame and a monitoring and using method thereof. Background technique [0002] Monitoring use means that parts do not meet the theoretical design and test requirements, and corresponding technical measures are taken to ensure that the parts can continue to be used safely. [0003] According to the development requirements of an aircraft, the target life of the canopy frame is 6,000 flight hours. However, due to irreparable damage to the glass in the fatigue test, the follow-up fatigue test was not completed. Therefore, in order to ensure flight safety, it is currently stipulated that the first repair The canopy frame needs to be replaced. The canopy glass is a brittle material. In the fatigue design of the canopy, the safe life criterion is used to determine the service life of the canopy, that is, only the crack...
