Projectile Delivery System With Variable Velocity Control

A launcher configured to attached to a pressurized air source, said launcher, comprising:

• a. a barrel with an open end;
• b. a ballast chamber with a closed end and a short bore section at the opposite end;
• said ballast chamber filled with pressurized air when said short bore section is closed;
• c. a conduit extending between said short bore section on said ballast chamber;
• d. a firing chamber with a conduit that connects to said ballast chamber;
• e. a piston rod that extends between said ballast chamber, through said firing chamber;
• f. a ballast piston attached to said piston rod and disposed inside said ballast chamber, said ballast piston has a surface area configured to close said short bore section in said ballast chamber when said ballast chamber is filled with pressurized air;
• g. a firing piston attached to said piston rod and located inside said firing chamber, said firing piston has a surface area larger than said surface area on said ballast piston;
• h. a velocity valve attached to said piston rod, said velocity valve configured to be set at different flow settings that limit the amount of longitudinal movement of said piston rod in said ballast chamber and thereby controlling the position of said ballast piston to partially or fully open said short bore section;
• i. a trigger coupled to said pressurized air source;
• j. a laser range finder coupled to said velocity valve, said laser range finder configured determine the distance to a target and automatically adjust said flow settings on said velocity valve so a projectile reaches said target;
• and,
• k. whereby when said laser range finder determines the distance to a target and said trigger is activated, said velocity valve is automatically adjusted to a desired setting, so said pressurized air from said pressurized air source flows into said firing chamber at a desired rate so that a projectile in said barrel reaches said target.
