Self-Propelled Football with Gyroscopic Precession Countermeasures

A self-propelled flying toy, comprising:

• a fan substantially centered about a longitudinal axis;
• a motor mechanically coupled to the fan;
• a power source energetically coupled to the motor;
• a centrifugal switch in electrical communication with the motor and power source controllably powering the fan when rotation about the longitudinal axis is detected and not powering the fan when rotation about the longitudinal axis is not detected;
• and
• at least two angled surfaces fixed relative to and ahead of the motor, where each of the at least two angled surfaces are substantially evenly centered about the longitudinal axis and facing an opposite thrust-generating rotational direction relative to the fan.

A self-propelled flying toy, comprising:

• a substantially oblate spheroidal body disposed along a longitudinal axis;
• a fan disposed within the body substantially centered about the longitudinal axis;
• a motor mechanically coupled to the fan and fixed relative to the body;
• a power source energetically coupled to the motor;
• and
• at least two angled surfaces fixed relative to the body and ahead of the motor, where each of the at least two angled surfaces are substantially evenly centered about the longitudinal axis and facing an opposite thrust-generating rotational direction relative to the fan.

A self-propelled flying toy, comprising:

• a fan centered about a longitudinal axis;
• a motor mechanically coupled to the fan;
• a power source coupled to the motor;
• an air-inlet in airflow communication with the fan disposed ahead of the fan and fixed relative to the motor;
• an air-outlet in airflow communication with the fan disposed behind the fan and fixed relative to the motor;
• and
• at least two fixed angled surfaces disposed ahead of the fan and fixed relative to the motor, wherein each of the at least two angled surfaces are evenly centered about the longitudinal and facing an opposite thrust-generating rotational direction relative to the fan.
