Firearm Muzzle Device Trajectory Correction via Gas Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms face accuracy limitations due to human physiological and environmental factors such as shaky hands and unpredictable vibrations, which degrade the precision of projectile aiming, especially at intermediate distances and in unstable conditions.
Innovation Solution
A system that uses a muzzle device to exert lateral gas-dynamic forces on projectiles, controlled by a microprocessor unit and sensors, to correct the trajectory and pointing errors by modulating high-pressure gases exiting the barrel, allowing for real-time adjustments to ensure accurate targeting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a marksman fires from a standing or offhand position without a steady bench rest, then the firearm is more portable and easier to operate, but the accuracy deteriorates significantly due to physiological jitters and shakes
Solution Approach 1:
The system captures the high-pressure exhaust gases that would normally be wasted and redirects them through selectively opened ports to generate corrective lateral forces on the projectile, converting a harmful waste product into a beneficial stabilizing mechanism that compensates for shooter instability
Solution Approach 2:
The exhaust gas flow acts as an intermediary medium between the firearm's propulsion system and the projectile, transferring momentum laterally to correct aiming errors without requiring direct mechanical contact or additional heavy stabilization equipment
2Manufacturing precision
If exhaust gases are directed toward the projectile to correct trajectory, then aiming accuracy is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The exhaust flow is divided into multiple discrete streams through separate ports positioned around the muzzle, allowing independent control of gas redirection in different directions to correct various types of aiming errors
Solution Approach 2:
The system uses the firearm's own exhaust gases and propulsion mechanism to provide stabilization, eliminating the need for external power sources, heavy counterweights, or complex mechanical stabilization systems
3Speed
If high-pressure gases are modulated to exert lateral forces on the projectile, then the effective engagement range is increased, but the loss of energy increases due to gas diversion
Solution Approach 1:
Only selective portions of the exhaust gas flow are redirected through specific ports to provide minimal corrective forces needed for stabilization, rather than diverting the entire exhaust stream, thus maintaining forward propulsion while achieving trajectory correction

AI summary
A firearm having an aim-compensation system. The firearm includes a barrel and is configured to fire a projectile. The firearm further includes a sensor disposed on the firearm that determines an orientation of the firearm. The firearm further includes a control unit that determines an intended point-of-aim of the firearm and an actual expected point-of-aim of the firearm based on the orientation of the firearm, and the control unit determines a differential of the intended point-of-aim and the actual expected point-of-aim. The firearm further includes a muzzle device arranged on the barrel which is in communication with the control unit, wherein, when the projectile is fired, the muzzle device directs a gas toward the projectile in an amount and direction based on the differential determined by the control unit so as to exert an aerodynamic force on the projectile to alter the trajectory of the projectile towards the intended point-of-aim.
