Abstract
A fuel injector for ducted rocket motors is provided that distributes compressible fluid fuel flowing from an upstream throttle device through discharge ports of a hollow tubular member without losing throttling capacity of the throttle device. The injector has an axial fuel flow passage with a cross-sectional area that decreases stepwise rearward of a radial discharge of the fluid fuel. The dimensions and position of the flow passages of the injector provide desired flow distribution while preserving the smoothness and regularity thereof.
