About this book

This book describes in detail a method of direct optimization, which makes it possible to choose the best trajectory of an aircraft in conditions of its limited resource. This can happen in the event of an emergency on board, associated with both a possible equipment failure and external influences, for example, when lightning strikes an aircraft or collides with a moving object. The highlight of this book is the fact that the results presented in it can be applied universally to the choice of the flight path of large and small aircraft, as well as helicopter technology. In addition, they take into account various conditions of aircraft flight, including a possible accident. The methods and algorithms presented here can be used as the basis for the creation of automatic collision avoidance systems, as well as the choice of the best aircraft trajectory for flights in different regions and in different conditions.

Chapter 1. Onboard Restraint Systems. State of the Issue. Formulation of the Problem
Abstract
Ensuring flight safety is one of the most important problems in aviation. Flight safety is determined by a large number of different factors. The ranking of these factors by their contribution to the accident rate, as well as the assessment of the accident rate itself, can be most reliably carried out, using statistical methods. Since aviation accidents are relatively rare events, a sufficient statistical sample can be obtained only with a flight of about 1.5 … 2 million hours. This is roughly equivalent to an annual flyover.

Chapter 2. The Method of Adaptive Maintenance of Constraints on the Components of the State Vector of a Dynamic System
Abstract
Consider an arbitrary dynamic object, whose behavior is described by some system of n ordinary nonlinear differential equations in the Cauchy form.

Chapter 3. Algorithms for Adaptive Limitation of Aircraft Flight Parameters
Abstract
In the first section, the disadvantages of the system of limiting the angle of attack with a fixed parameter setting were considered.

Chapter 4. Algorithms for Adaptive Limitation of Trajectory Parameters of Aircraft Movement
Abstract
Let be in the normal coordinate system.

Chapter 5. Aircraft Drift Away from Limiting Surfaces Along Programmed Trajectories
Abstract
This section presents an approach to the construction of algorithms for systems for maintaining restrictions in the trajectory circuit of aircraft’s control, based on the preliminary assignment of the trajectory of the AC movement.

Chapter 6. Method and Algorithms for Direct Optimization of the Movement of a Damaged Aircraft
Abstract
When solving problems of organizing the control of a damaged aircraft, the question very often arises: how sufficient are the remaining control resources to reach certain areas of space from the current or given state? If such areas are achievable, then what kind of trajectory does it have?
