Abstract : This abstract describes a partial swirl augmentor for a turbofan engine having an annular duct for directing hot gases into the augmentor combustion chamber. Located within the combustion chamber is a piloted vee-gutter flameholder system which has a circumferential pilot located at the outer edge of the swirling hot turbine exhaust gas stream. As a result thereof, the partial swirl augmentor can attain state-of-the-art engine after burning thrust levels with an increased altitude blow-out limit. (Author)
