The experimental measurement and the analysis of the recoil forces of the selected shotguns were carried out systematically after selecting the accurate piezoelectric force sensor for the dynamic performance of the recoil mechanism. The experimental setup required for the measurement was built via integrating the selected piezoelectric force sensor, signal conditioner, data acquisation card with a software developed in Visual Basic .NET software language. A developed measuring apparatus was designed to measure the dynamic recoil forces of different shotgun system. The selected piezoelectric force sensor can detect the recoil forces with 36 kHz measurement capacity. All of the data were recorded in real-time. The recorded data were examined, and analyzed comparatively. The collected measurement results are evaluated according to the recoil mechanisms, barrel lengths, weights, and other effective parameters that may affect the recoil forces in the experimental analysis. It was observed that the shotgun that spreads the recoil force over time reduces the peak point and has minimum total recoil energy among the gas cycle, inertia and hybrid shotguns with 71cm barrel length and included 12GA caliber.

were carried out. Different rifle and shotgun types and working mechanisms have
been examined, and their mechanical systems are explained. By investigating the
formation and effects of recoil forces, research and literature review on how these
forces can be measured has been carried out. The experimental infrastructure
required for measurement was created with a piezoelectric force sensor, signal
conditioner, data acquisition system and a computer using software developed for
this study in Visual Basic .NET programming language. A measuring fixture has
been designed and manufactured to bring together all these equipment and the rifles
to be shot on. With this fixture and equipment, more than 600 shots were made with
28 different rifles on the range. The shots were measured by a piezoelectric sensor
with a measurement capacity of 35 kHz and all data were recorded in real time.
Some of these rifles and shots were evaluated, examined and analyzed
comparatively.
The measurements made were evaluated and interpreted by considering the working
mechanisms of the rifles, barrel lengths, weights and other components that may
affect the recoil forces. According to the results obtained from the measurements, it
has been determined that the moment when the bullet leaves the barrel can be
determined from the recoil force graph of a gun. In the comparison of 12GA caliber
gas operated, kinetic and hybrid semi-automatic shotguns, it was seen that the hybrid
shotgun had the least recoil energy and it was predicted that the reason for this was
the pressure control in the barrel. The kinetic semi-automatic shotgun was the model
with the highest recoil energy. In addition, it is predicted that the movements of the
inertia springs of the kinetic shotgun and the movements within the mechanism can
be observed in the recoil force graph. Similar shotguns were compared by shooting
with different barrel lengths, and the effect of the barrel length on the recoil force
was observed. While the recoil force tends to decrease with the length of the barrel in
hybrid and gas cycle models with gas holes in the barrel, the opposite is observed in
kinetic rifles. In the trials of the muzzle brake part made with rifles, it has been seen
that the muzzle brake can be effective up to 49% on the peak value of the recoil
force, while reducing the total graphic area by 22%.
