Aerospace series - Programme management - Verification and validation of numerical models and simulations

This document provides an inventory of best practices, shared by actors from the aerospace and defence sector, concerning the verification and validation (V&V) of numerical simulations and models, in order to ensure the credibility of the outputs obtained in a logic of faster development of decision-making support, of reducing the number of physical tests, of shortening development times, of facilitating numerical qualification and certification, etc. These are all the major challenges concerning simulation. The approach applies to models based on physical equations. EXAMPLE Mechanics, acoustics, electrical, electromagnetism, thermal physics for electronics, fluid dynamics, multibody dynamics, multiphysics, optical, signal integrity and power integrity. The objective is to determine recommendations depending on the challenges of the simulation, in order to adapt the procedures to be applied to ensure the credibility of the simulation. The items being considered are: - criticality of the product and the simulation; - complexity of the phenomenon or the product; - capability, fidelity and maturity of the model; - product lifecycle; - skills; - verification and validation approach, with uncertainties quantification; - etc. This document is organized as follows: - terms and definitions; - general principles and concepts of simulation V&V: o the document’s objectives and added value; o state of the art; o different uses of simulation depending on the maturity (approximation level) of the model and product lifecycle, linked to the expected fidelity of the model and the simulation outputs; o presentation of the different types of models and impacts on criteria and quantities of interest, as well as on requirements; - recommended V&V process and activities (linked to the degree of maturity); - an example of a simulation plan template; - examples for a clearer understanding. The aim of this document is to complete and reference the information available in the literature. This document takes a generic approach so that it is applicable by most organizations and for different types and domains of simulation. This document addresses simulation specialists, simulation team managers and other stakeholders involved in the simulation process or decision-making support. This document provides recommendations for each criticality level, linked also to the level of confidence in the simulation, at each stage of the simulation process. Modelling and simulation have long been part of product qualification and certification, and the recommendations laid down in this document do not aim to replace the many qualification, certification and analysis processes already proven and established. The practices recommended in this document were specifically developed in response to potential future applications of modelling and simulation which could, in some cases, give it a more prominent role in qualification and certification, thereby reducing programme costs and development times.

Pliūpsnio temperatūros nustatymas. Modifkuotas nuolat uždaro tiglio pliūpsnio temperatūros (MCCCFP) metodas (ISO/DIS 24966:2025)

This International Standard specifies a test method for the determination of the flash point of chemicals, lube oils, aviation turbine fuel, diesel fuel, diesel/biodiesel blends and other liquids by a continuously closed cup tester utilizing a specimen size of 2 ml, cup size of 7 ml, with a heating rate of 2.5 °C per minute. This flash point test method is a dynamic method and depends on definite rates of temperature increase. It is one of the many flash point test methods available and every flash point test method, including this one, is an empirical method. It utilises an electric arc as the ignitor and detects the flash point by pressure measurement.This test method is suitable for testing samples with a flash point from 22,5 °C to 235,5 °C. Flash point determinations below 22,5 °C and above 235,5 °C may be performed, but the precision has not been determined.

These measures provide the last means of protection when all other possibilities of preventing an accident have failed, i.e. — design provisions for the vehicle front to minimize the impact effect on a pedestrian when hit, — design provisions for the vehicle front for side (lateral) deflections in order to minimize the risk of being drawn under the vehicle on flat ground (embedded track), — design provisions for the vehicle body underframe to not aggravate injuries to a pedestrian/body lying on the ground, — provisions to prevent the pedestrian from being over-run by the leading wheels of the vehicle. This document focuses on the consequences of the primary and tertiary impact. The consequences of a secondary impact are out of the scope of this document. The following measures to actively improve safety are not in the scope of this document: — colour of front; — additional position lights; — additional cameras; — driver assistance systems; — additional acoustic warning devices, etc.; — view of the driver / mirrors; — consequences for pedestrian injuries due to secondary impact with infrastructure (side posts, concrete ground, poles, trees, etc.).
