Turbine Preliminary Design Using Artificial Intelligence and Numerical Optimization Techniques

Abstract: This paper describes a new software approach to the preliminary design of aircraft engine turbines. A hybrid artificial intelligence and numerical-optimization-based design shell called Engineous was used to capture some basic turbine preliminary design knowledge, manipulate turbine design parameters, execute a turbine performance prediction program and its preprocessors, and analyze results. Engineous automatically supplements incomplete human design knowledge with symbolic and numerical search techniques whe… Show more

“…The benefits of using a GA to design and optimize a model in a set design space have been well documented. A few specific aerospace applications include the design and optimization of propellers 5 , freight truck aerodynamics 6 , wings and airfoils 7,8,9,10 , rockets 11,12 , missiles 13,14,15,16,17,18 , flight trajectories 19 , spacecraft controls 20,21 , and turbines 22,23,24 . The final solution is the member that has the best fitness at the end of the last generation.…”

“…Today, several other design methods are available such as gradient methods based on finite difference [3] or more recently based on the sensitivity and the adjoint equation [4], genetic algorithm [5], simulated annealing, response surface methods, inverse design [6] or expert systems [7]. All these methods have advantages and disadvantages and cannot cover the whole field of design problems.…”

“…Furthermore, oftentimes these problems are black-box problems, i.e., whose problem class is unknown, and they are possibly mathematically ill-behaved (e.g., discontinuous, non-linear, non-convex). For example, most engineering design problems are of this type (see e.g., [12]). They require experiments and/or simulations to evaluate to what extent the design objective has been met as a function of parameters controlling the design.…”
