To elaborate just a teensy bit further, aperture is a ratio of focal length/diameter (of the hole created by the blades), so the longer your focal length is, the "smaller" your aperture is.
In this case then the hole created by the blades needs to become larger as you zoom out on a constant aperture zoom lens. If this is the case could not the aperture then be larger lets say 1.4 and go to 2.8 as you zoom out. Just a question.
