Procedure and mathematical models for the validation of requirements to combat aircraft with account of ensuring its survivability and damage tolerance on exposure to means of destruction

Abstract

The necessity of creating a complex of mathematical models of the functioning of a combat plane in conditions of exposure to means of destruction to resolve the possible inconsistency of the plane’s tactical flight properties and performance characteristics is validated in the article. The developed scheme of the procedure of assessing the impact of weapons on the aircraft is presented. The scheme allows justification of the design and layout solutions and circuitry to ensure combat survivability, research and analysis of the damage tolerance of the airframe elements under various conditions of the weapon-aircraft rendezvous, including the early stages of design. The principles underlying the development of mathematical models for the formation of the spatial-geometric structure of the aircraft on the basis of its three-dimensional solid-state configuration, simulation of the weapon warhead detonation with the formation of the field of damage agents, aircraft coverage with damage agents with the definition of the facts of their hitting the aircraft are outlined. The technique makes it possible to produce multiple statistical modeling of the process of impact of standard means of destruction on the aircraft with the assessment of characteristics of combat damage of the airframe structures. The individual kinematic characteristics of each damage agent of the weapon warhead in the contact with the elements of the aircraft structure, taking into account the mass and aerodynamic forces are calculated. Examples of the developed mathematical models are given.
