Method for predicting temperatures which are tolerable by a component, a piece of equipment or an airplane structure

Abstract

A method for predicting temperatures tolerable by a component, a piece of equipment or a vehicle structure. This method includes the steps of determining, for each piece of equipment, component or structure of the vehicle, such as an airplane, a temperature spectrum depending on a plurality of extrinsic parameters measured during a full operating cycle of the airplane, by taking into account, for each piece of equipment, component or structure, possible combinations of the extrinsic parameters and setting aside unlikely combinations of the extrinsic parameters, determining, for each piece of equipment, component or structure, the probability of occurrence of the spectrum during the full airplane operating cycle, and defining a database including the temperature spectra so as to predict the lifetimes of the piece of equipment, component or structure and redefine weather and operational standards indicating extreme temperatures and their probability of occurrence obtained with the measured extrinsic parameters.

Description

technical field [0001] The present invention relates to thermal analysis for predicting the permissible temperature range of components, equipment or structures of vehicles such as airplanes, helicopters, rockets, satellites, trains, motor vehicles, buses or ships. [0002] The invention also relates to means intended to implement the method according to the invention and to a computer program stored on a storage medium. [0003] These temperature ranges are then used, for example, to calculate loads and structural stress fields for environmental masses, especially hot / cold temperature ranges for materials and equipment, or these temperature ranges are even used to check the operational durability of these equipment and these structures. Background technique [0004] Thermal analysis refers to all means that make it possible to estimate the temperatures tolerated by components, equipment or structures of a vehicle. This estimation relies on the analysis of the laws of physi...

[0008] Another disadvantage with regard to these techniques stems from the fact that the conditions of actual use of the vehicle make it far from being able to achieve the level of theoretical calculations

Furthermore, prior art methods do not know the probability of reaching these temperatures and therefore cannot define margins relative to the actual conditions of the operation
