Claims
- 1. A weapon of the kind used for combat troop engagement simulation and comprising,
- an automatic weapon having certain original parts removed,
- automatic weapons effects simulator (AWESS) means integrated directly into the weapon in place of the removed original parts for producing the visual and acoustic signatures associated with firing of the weapon while allowing the weapon operator to operate and utilize the basic weapon mechanism in the same manner as with the original parts, but without firing projectiles from the weapon,
- said AWESS means comprising,
- expendables supply means for supplying expendables including fuel, oxygen and batteries necessary for operation of the AWESS means,
- chamber barrel assembly means for providing a combustion chamber and related apparatus used to produce the visual and acoustic signatures, and
- receiver unit means for containing the elements and functions which most directly interact with weapon operation, such as, for example, trigger, safety, rate of fire switch, single shot, and burst fire operation.
- 2. The invention defined in claim 1 including adapter means for permitting a single AWESS means to be used in more than one type of weapon.
- 3. The invention defined in claim 2 wherein the chamber barrel assembly means include a firing pin rod and wherein the adapter means cause the firing pin rod to be in exact alignment with the firing pin of the weapon receiver such that mechanical motions of the firing pin in the weapon receiver are transmitted to the firing pin rod in the chamber barrel assembly means.
- 4. The invention defined in claim 1 wherein the fuel is a liquid fuel and the chamber barrel assembly means include electric spark means for igniting the fuel and the oxygen in the combustion chamber so that the simulated operation of the weapon is obtained at low cost as compared to the cost of blank ammunition.
- 5. The invention defined in claim 3 wherein the expendables supply means comprise fuel and oxygen pressure regulators required to establish gas pressures necessary for proper combustion and spark drive circuitry for controlling the electric spark means.
- 6. The invention defined in claim 5 including timing circuit means for disabling the spark drive circuitry for a period which simulates the time to reload the weapon.
- 7. The invention defined in claim 3 wherein the chamber barrel assembly means includes fuel and oxygen flow control valve and switches for trigger, rate of fire and reset.
- 8. The invention defined in claim 1 wherein the AWESS means are incorporated in an M85 machine gun for operation with the bolt slide and operating handle of the M85 weapon.
- 9. The invention defined in claim 8 wherein the receiver unit means include cam and switch means for doubling the spark repetition rate for high rate of fire operation as compared to low rate of fire operation.
- 10. the invention dfined inclaim 1 wherein the AWESS means includes burst fire bar means which pivot about a trigger lever pin of the weapon to permit operation in a single shot mode or in a burst fire mode with full depression of the trigger in exactly the same manner as occurs by operation of the trigger in the actual weapon without the AWESS means.
- 11. The invention defined in claim 1 wherein the chamber barrel assembly means include valve means controlling the flow of fuel and oxygen to the combustion chamber, electric spark means for igniting the mixture of fuel and oxygen in the combustion chamber, and including spark drive circuitry for controlling the electric spark means and wherein the valve means are actuated to an open position to provide a continuous flow of fuel and oxygen to the combustion chamber and the spark drive circuitry controls the rate of repetition of firing of the weapon by intermittent sparks.
- 12. A method of simulating operation of a weapon of the kind used for combat troop engagement simulation in a way that requires normal weapon operation to produce the simulated operation, said method comprising,
- removing certain original parts from an automatic weapon,
- replacing the removed original parts with automatic weapons effects simulator AWESS parts which include a combustion chamber, and
- integrating the AWESS parts directly into the weapon to produce the visual and acoustic signatures associated with firing of the weapon while allowing the weapon operator to operate and utilize the basic weapon mechanism in the same manner as with the original parts, but without firing projectiles from the weapon.
- 13. The invention defined in claim 12 including injecting a liquid fuel and oxygen into a combustion chamber and igniting the mixture in the combustion chamber by an electric spark to produce the visual and acoustic signatures at low cost as compared to the cost of producing such signatures by blank ammunition.
- 14. The invention defined in claim 11 including supplying a continuous feed of fuel and oxygen to a combustion chamber of the weapon and controlling the simulated rate of fire by controlling a spark repetition in the combustion chamber.
