Blade-stator system, and vertical takeoff and landing flying device including same

A vertical take-off and landing flight apparatus comprising:

• a flight body;
• and
• a blade-stator system,
• wherein the blade-stator system comprises:
• a duct disposed inside the flight body, upper and lower sides of the duct being open, and an inside of the duct being hollow;
• a blade assembly installed rotatably inside the duct and including a blade body of which an angle is changeable;
• a stator assembly connected to the blade assembly and the duct, supporting the blade assembly;
• a controller electrically connected to the blade assembly and the stator assembly and configured to control driving of the blade body and the stator assembly,
• wherein the stator assembly comprises:
• a fixed stator connecting the duct to the blade assembly and of which a position is fixed;
• and
• a variable vane rotating with respect to the fixed stator;
• and
• a vane driver connected to the variable vane and transmitting a rotational force to the variable vane,
• wherein the variable vane is disposed between the blade assembly and the fixed stator so that air is configured to flow from the blade assembly toward the variable vane and then to the fixed stator, and
• wherein the controller adjusts a rotation angle of the variable vane to correspond to a change of a pitch angle of the blade body.

A blade-stator system comprising:

• a duct disposed inside a flight body, wherein upper and lower sides of the duct are open, and an inside of the duct is hollow;
• a blade assembly installed rotatably inside the duct and including a blade body of which an angle is changeable;
• a stator assembly connected to the blade assembly and the duct, supporting the blade assembly, and rotatable by a predetermined angle;
• and
• a controller electrically connected to the blade assembly and the stator assembly and configured to control driving of the blade body and the stator assembly,
• wherein, an angle of the stator assembly is predetermined based on the angle of the blade body, and
• wherein, in response to an electrical signal from the controller, the angle of the stator assembly is changed as to be interlocked with a change of the angle of the blade body.
