Claims22
A flight vehicle, comprising:
- a flight structure;
- an engine mounted to the flight structure and configured to discharge a pressurized flow for providing propulsive thrust to the flight structure;
- a nozzle system configured to receive and accelerate the pressurized flow, wherein the nozzle system includes a converging nozzle and a throat having:
- an inflection;
- a first throat portion extending from one side of the inflection and providing a first throat flow area;
- and a second throat portion extending from another side of the inflection and providing a second throat flow area, wherein the first throat portion and the second throat portion each face in different directions,
- wherein the nozzle system is configured to discharge a first portion of the pressurized flow from the first throat portion in a first direction, and to discharge a second portion of the pressurized flow from the second throat portion in a second direction different from the first direction.
4 more elements
A propulsion system, comprising:
- an engine configured to discharge a pressurized flow;
- a nozzle system configured to receive a pressurized flow, wherein the nozzle system includes a nozzle, an inflected throat and at least two fluidic injection zones, wherein the inflected throat includes a first throat portion having a first throat flow area, and a second throat portion having a second throat flow area, wherein the first throat portion and the second throat portion face different directions,
- wherein the nozzle system is configured to discharge a first portion of the pressurized flow from the first throat portion in a first direction by reducing flow through the second throat portion using at least a second fluidic injection zone, and to discharge a second portion of the pressurized flow from the second throat portion in a second direction different from the first direction by reducing flow through the first throat portion using at least a first fluidic injection zone.
A thrust vectoring system, comprising:
- a nozzle system configured to receive a pressurized flow and accelerate the pressurized flow, wherein the nozzle system includes:
- means for generating a yaw moment in a first yaw direction using the pressurized flow;
- and
- means for generating a yaw moment in a second yaw direction using the pressurized flow.
