Abstract
A propulsion apparatus is provided with a gas generator and a plurality of thrusters. The gas generator generates combustion gas when a flying body satisfies an emergency condition. Herein, the plurality of thrusters output the combustion gas downward. In addition, when viewed from a direction of travel of the flying body, the plurality of thrusters may overlap the gas generator. Furthermore, the plurality of thrusters may control an attitude of the flying body. In addition, the plurality of thrusters may reduce outputs of the combustion gas to a first output based on a landing of at least a part of the flying body.
Claims14
A propulsion apparatus for a flying body, comprising:
- a processor;
- a gas generator configured to generate combustion gas;
- a measuring device to generated status information of the flying body;
- and
- a plurality of thrusters configured to output the combustion gas downward,
- wherein the processor is configured to receive the status information of the flying body from the measuring device;
- based upon the status information, predict the flying body is to land in an area;
- determine whether at least one part of the flying body satisfies an emergency condition, determine the emergency condition is the at least one part of the flying body is predicted to land in the area, to cause the gas generator to generate the combustion gas upon determining that the at least one part of the flying body satisfies the emergency condition, and control the plurality of thrusters so that the at least one part of the flying body lands outside the area;
- wherein the processor is further configured to determine whether the at least one part of the flying body is landed, to reduce an output of the combustion gas to a first output by which the flying body does not rise upon determining that the at least one part of the flying body is landed, and to cause the gas generator to continue outputting the combustion gas at the first output after the at least one part of the flying body is landed, and
- wherein the processor is further configured to control outputs of the thrusters based on an altitude and a speed of the flying body.
