They weigh the person and use some form of scientific calculation to see how far a certain amount of powder will shoot it at different angles or something like that.Nearly forgot the beard is used to seal the barrel of the cannon to prevent the expanding gases from leaking out before they have been used to propel the idiot inside. :-)
I imagine the only purpose of the beard is to demonstrate that only crazy people get shot out of cannons, and having a beard makes him look crazier.
The biggest headache is that a human being is a very complex aerodynamic shape, and that the charge will have to be adjusted if the guy being blasted out significantly changes weight. All of that said, as I said, the firing range is very short, so the scope for error is limited.It is easy enough to put some wad between the charge and the projectile, just as is used with shot guns, and would have been used with muskets in the past. The wad will improve the seal between the charge and the lining of the barrel, and by preventing the gas escaping forward will also protect the projectile from the heat of the gas.
Calculating the trajectory of a cannon shell is very important in battlefield conditions if you are going to hit your target
Calculating the trajectory of a cannon shell is very important in battlefield conditions if you are going to hit your target. It is easier to do with a cannon shell that is rigid and of a simple shape designed for its purpose than it is for a human body that might wriggle
a silly way to put this. but, if the man had an itch on exiting the barrel and tried to scratch it. would he change the trajectory and miss the net?
These days its a lot easier to hit your target with an artillery shell as the new generation coming in now have built in Satnav and can steer themselves onto their targets even if they have been fired in a direction which should take them ten miles of course.
Not sure if these are the same as the ones i heard about but their similarTrajectory Correctable Munition (TCM) ...sorry, you cannot view external links. To see them, please

I think most human cannons are actually powered by big springs, the explosion is just for effect. I guess you test it with something about the same weight as a human and start off firing the person not very far, then crank up the spring slowly as you move the net outwards..
