چکیده
This paper describes an effort to discover the highest practical flight velocity possible using air-breathing propulsion powered vehicles. The methodology includes modeling of all the key performance characteristics of a hypersonic vehicle along with a genetic algorithm based optimization study. A flexible and robust geometric modeling scheme based primarily on the use of Bernstein polynomials is used to defining the vehicle outer mold line. A supersonic paneling scheme is used along with a viscous skin friction model to predict aerodynamic performance and a generalized one-dimensional approach is applied to the combustor section. Also included is a simplified structural model. The results are a step forward for practical hypersonic vehicle design.

Optimization of Air-breathing Hypersonic Aircraft Design using Euler Codes and Genetic Algorithms
An advanced, modular paneling scheme has been developed for atmospheric flight vehicles with an aim of predicting the drag during hypersonic flight. A generic, three-dimensional grid generation algorithm has been developed for this effort that allows the construction of detailed aircraft geometries using the concept of geometric overlap in three-dimensional spaces. The use of Bernstein polynomi...

-The scramjet performance of air-breathing hypersonic vehicle is highly correlated with flight height, Mach and angle of attack (AOA). The violent disturbance of the AOA can cause the engine power off. Consequently, the maneuverability of hypersonic vehicle is strictly limited in the cruising period. A composite control system for an air-breathing hypersonic vehicle is presented. The hypersonic...

This paper examines the use of a hypersonic bi-directional flying wing concept for use in a high efficiency hypersonic system. The bi-directional flying wing concept consists of a symmetric planform which enables flight to occur at two different geometric configurations. The subsonic configuration would have a high aspect ratio and a low sweep. The aircraft would then rotate 90 degrees and ente...

In this paper multi-objective genetic algorithms were employed for Pareto approach optimization of turboprop engines. The considered objective functions are used to maximize the specific thrust, propulsive efficiency, thermal efficiency, propeller efficiency and minimize the thrust specific fuel consumption. These objectives are usually conflicting with each other. The design variables consist ...
