Hunter
Design philosophy and key properties of Vanward suppressors
Vanward suppressors is 3D printed in grade 5 Titanium in one piece to achieve maximum strength and safety in combination with the lowest weight and noise reduction possible.​
​
Vanward Hunter series is designed specifically for the hunter and shooter requirements.​
Where noise and recoil reduction together with low volume/diameter and weight is the main drivers.
Vanward specific design
How suppressors work - or should work
-
The suppressor must have adequate volume and baffle design to;​
a) Reduce the recoil by capturing the gasses as it expands , thus generating a force working in the opposite direction of the recoil forces ​
b) Reduce the speed of the gas expansion and to mix and generate turbulence in the gases to reduce the noise.​ -
The suppressor must have the mechanical properties to withstand all relevant factors from the use, including safety margins ​
a) Mechanical strength - both Yield strength and high fatigue stress resistance​
b) High temperature resistance​
c) Corrosion resistance​ -
Low weight​
-
Minimum maintenance ​
​
For Vanward, only Titanium (and Inconel) is acceptable material to be used in suppressors and 3D printing is the only option to manufacture.
Acoustic and recoil reduction
Background and theory
-
The speed of sound is depending on temperature, air density/humidity and atmospheric pressure, where temperature is the most dominant factor.​
-
At 20 deg. C the speed of sound is 343,3 m/s.​
-
Sound is a form of overpressure in the air and is measured in dB​
-
3 dB increase (or decrease) represent a doubling (or half) of the sound pressure level​
-
To the human ear, a 10 dB change in the sound level will represent a doubling of the perceived loudness.​
-
Typical noise level from an unsuppressed .30 cal. rifle is approximately 165 - 171 dB​
-
Maximum SAFE peak sound level from a rifle is 140 dB (MIL-STD-1474D) at shooters ear.​
-
Firearm sound is generated by:​
- Muzzle Blast​
- Bullet breaking sound barrier​​
A typical .30 cal. cartridge fired in a standard barrel represents approximately:​- Muzzle pressure at 850 bars, gas velocity of 900 - 1000 m/s and in total 150-170 liters of gas expanded to atmospheric conditions.
Firearm sound is generated by
​
Muzzle blast and supersonic crack from bullet (If not subsonic)​
​
-
Muzzle blast - Primer and powder ignition together with sudden release of high pressure, hot propelling gases in bore creating a shockwave by the muzzle.​
​
Sound of the bullet in flight
​
Breaking the sound barrier (ballistic crack) which is generated outside the weapon as long as the bullet flies faster than the speed of sound and cannot be addressed by a suppressor​
This sound is very difficult to locate where it comes from as it is a continuous generated sound wave
