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.

A thruster control device has an opening degree estimating section and an opening degree control section. The opening degree estimating section calculates an estimated opening degree of a valve showing a rate at which the valve is opened, based on a balance of an acting force applied to a valve element of the valve to adjust a quantity of combustion gas to be ejected from a thruster and a fluid force applied to the valve element by the ejected combustion gas. The opening degree control section determines a target opening degree based on the estimated opening degree to control the opening degree of the valve.
