Abstract
A projectile launcher comprises a motor driven flywheel having a rotational axis and a roughened circumferential edge surface, and a flywheel housing having a passageway therethrough. The passageway comprises an entry opening at a first end that is configured to receive at least one disc projectile, and a release opening at a second end.
Claims20
A projectile launcher, comprising:
- a motor driven flywheel having a rotational axis and a roughened circumferential edge surface, wherein the motor driven flywheel is driven at a rotational speed of approximately 24,000 revolutions per minute;
- and
- a flywheel housing having a passageway therethrough, the passageway comprising an entry opening at a first end that is configured to receive at least one disc projectile, and a release opening at a second end;
- and
- idler bearings positioned at the entry opening and at the release opening, the idler bearings configured to provide consistent point of release and rotation of each of the at least one disc projectile wherein the launcher is configured to fire projectiles at a rate of approximately 6.5 projectiles per second in automatic firing mode.

A projectile launcher, comprising:
- a motor driven flywheel having a rotational axis and a circumferential edge surface, wherein the motor driven flywheel is driven at a rotational speed of approximately 24,000 revolutions per minute;
- a flywheel housing having a curved passageway therethrough, the curved passageway comprising an entry opening at a first end that is configured to receive at least one disc projectile, and a release opening at a second end, wherein the curved passageway spans a 45-degree arc of contact between the entry opening and release opening to provide extended contact time between the motor driven flywheel and the at least one disc projectile, resulting in increased acceleration;
- and
- idler bearings positioned at the entry opening and at the release opening, the idler bearings configured to provide consistent point of release and rotation of each of the at least one disc projectile wherein the launcher is configured to fire projectiles at a rate of approximately 6.5 projectiles per second in automatic firing mode.

A projectile launcher, comprising:
- a firing mechanism comprising:
- a motor driven flywheel having a rotational axis and a circumferential edge surface, wherein the motor driven flywheel is mounted on bearings to enhance smooth rotation and increase lifecycle expectancy, and wherein the motor driven flywheel is driven at a rotational speed of approximately 24,000 revolutions per minute;
- and
- a pusher actuated in a reciprocating cycle by a motor driven rotating cam, wherein the motor driven rotating cam is mounted on bearings to enhance smooth rotation and increase lifecycle expectancy, and wherein the motor driven rotating cam is made of metal to withstand greater heat and forces at high rotation rates;
- and
- a magazine configured to provide a biasing force on at least one stack of one or more disc projectiles;
- wherein
- the pusher is configured to push a top disc projectile off the at least one stack of one or more disc projectiles on a forward stroke of the reciprocating cycle, and the motor driven flywheel is configured to engage the top disc projectile to impart acceleration thereto;
- and wherein the launcher is configured to fire projectiles at a rate of approximately 6.5 projectiles per second in automatic fire mode.
