Crossbows shoot arrow-like projectiles called bolts or quarrels.
As bow shocks occur for high flow deflection angles, they are often seen forming around blunt bodies, because of the high deflection angle that the body impose to the flow around it. The thermodynamic transformation across a bow shock is non-isentropic and the shock decreases the flow velocity from supersonic velocity upstream to subsonic ...
Typical arrows with three vanes should be oriented such that a single vane, the "cock feather", is pointing away from the bow, to improve the clearance of the arrow as it passes the arrow rest. A compound bow is fitted with a special type of arrow rest, known as a launcher, and the arrow is usually loaded with the cock feather/vane pointed ...
A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw , when it seems that the arrow would have to pass through the starting position it was in before ...
