A systematic design methodology for generating the optimal repairs of aging aircraft
نویسندگان
چکیده
A design methodology which generates optimal mechanical repairs for aging aircraft is presented. Finite element modeling and analysis is used to evaluate the repairs. The repair problem is formulated as an optimization problem using an energy criterion. Optimal locations for rivet placement are found for many different situations.

Solar Energy System Design of Ultralight Aircraft for Smoke Detection and Fire Alarm Proposes
Abstract: The purpose of this paper is to design and evaluate the construction of a lightweight solar aircraft that is capable of flying continuously for 24 hours relying solely on solar energy. The required energy is absorbed during the day by solar panels, some is used directly for flight, and the excess energy is stored in the aircraft battery for overnight flight. The aircraft will then be ...
متن کاملAutomatic Landing Guidance Systems and Design of an Optimal Landing Control System
Guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. In this study automatic landing control systems are introduced and an optimal landing control system is designed. The control system performance criteria are based on minimum control effort. The designed system is simulated for a tr...

This paper introduces a reliability-based multi-objective design method for spatial truss structures. A multi-objective optimization problem has been defined considering three conflicting objective functions including truss weight, nodal deflection, and failure probability of the entire truss structure with design variables of cross sectional area of the truss members. The failure probability o...
