THE USE OF A COANDA-EFFECT NOZZLE FOR MULTI-DIRECTIONAL CONTROL OF A COMPRESSIBLE FLUID JET.
Abstract
An experimental investigation was conducted to determine whether a three-dimensional Coanda-Effect nozzle with parallel secondary control injection could be used for the multi-directional control of an air jet. The divergent section of the nozzle was divided into four flow channels which were altered in size and shape. A discussion of the critical nozzle parameters and their effects on the flow pattern is presented. A configuration was determined which would contain the jet within a selected channel. Lateral to axial thrust ratios of 0.46 were achieved. This configuration has possible application in the fields of fluid amplifiers and thrust vector control. (Author)
