Title:
PROPULSION DEVICE, FLYING OBJECT, AND PROPULSION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/161873
Kind Code:
A1
Abstract:
This propulsion device comprises a gas generator and a plurality of thrusters. The gas generator generates combustion gas when a flying object satisfies emergency conditions. Here, the plurality of thrusters output the combustion gas downwards. The plurality of thrusters may overlap the gas generator when seen from a traveling direction of the flying object. Moreover, the plurality of thrusters may control the attitude of the flying object. Further, the plurality of thrusters may decrease the output of the combustion gas to a first output, on the basis of landing of at least a part of the flying object.
