| Abstract: | The objective of nozzle guide vane placement in the nozzle of a gas turbine engine is to attain uniform flow about the circumference of the nozzle. The vane placement problem is modeled as a traveling salesman problem with a special cost structure. Exploiting properties of the special forms of the cost matrix, a heuristic solution procedure is presented and its effectiveness on both real and simulated data is demonstrated. In addition, an algorithm is stated, that can be used to compute an a posteriori lower bound on the quality of the solution generated by the heuristic. Finally, theoretical results are contained that justify the proposed algorithms. |
