What is Air cannon: Definition and 20 Discussions

Cannon Air Force Base is a United States Air Force Base, located approximately 7 miles (11 km) southwest of Clovis, New Mexico. It is under the jurisdiction of Air Force Special Operations Command (AFSOC). The population of the Cannon AFB CDP was 2,245 as of the 2010 census. The host unit at Cannon is the 27th Special Operations Wing (27 SOW), which activated on 1 October 2007, and is assigned to the Air Force Special Operations Command (AFSOC). The 27 SOW plans and executes specialized and contingency operations using advanced aircraft, tactics and air refueling techniques to infiltrate, exfiltrate and resupply special operations forces (SOF) and provide intelligence, surveillance and reconnaissance and close air support in support of SOF operations.
Cannon AFB was established in 1942 as Army Air Base, Clovis. The commander of the 27th Special Operations Wing is Colonel Tony D. Bauernfeind. The Command Chief Master Sergeant is Paul J Henderson II.A variety of special operations aircraft are stationed at Cannon, including the AC-130W Stinger II, MQ-1 Predator, MQ-9 Reaper, CV-22 Osprey and several versions of light and medium transport aviation aircraft. The AC-130W is assigned to the 73rd Special Operations Squadron, with all twelve becoming operational in 2010.

    Optimization of barrel length in pneumatic cannons

    I was checking bait cannons and potato guns on the internet because they are fun. Maybe one day I'll build my own. First of all, these cannons use multiple sources of energy (combustion using hair spray, dry ice, etc.). I'll just consider compressed air cannons because I think they are the most...

    Air Cannon Air Speed Calculations

    I am working on an Air Blast Cannon for work and am having trouble finding the proper formulas to calibrate it. This Cannon needs to have a barrel with about a 4 inch bore. It will only be used to generate high speed air blasts, so it will not have a projectile. Are there any formulas or online...

    How do you control an Electronic Butterfly Valve with PID

    The butterfly valve I have is controlled by sending voltages to it. It accepts 0-10V and maps a specific voltage to a specific position from completely closed (zero degrees) to completely closed (90 degrees). To clarify/reiterate it is not controlled by a servo motor. I am using this valve to...

    Is My Air Cannon Safe After Winter?

    I left my Air cannon outside during the winter. I was wondering if it is still safe to use or if the cold might have left it unsafe. The air tank is made of 2 PVC caps attatched to a PVC T pipe, in between there is ABC pipe spacers... The center of the T pipe is connected to a valve, which...
