Richard, you're just making stuff up now. Nowhere has Miles ever said that a constant velocity is an acceleration and I defy you to provide evidence of such a claim from any of his papers. I'm beginning to question whether you have even read that paper your are criticizing. An acceleration is a change in velocity (and Miles says as much), it is TWO (at least) velocities superimposed over the same time interval. Now, there are only two ways to combine velocities in the same time interval: you can add them together, which would only give you a faster velocity and not an acceleration. Or you can multiply them integrating the second velocity on top of the first velocity over each interval of time, which would give you an acceleration. That's exactly what Miles is doing in multiplying the velocities together. An acceleration is not just one velocity tacked onto another, its the 'velocitizing' of the first velocity by the second. The first velocity is changing according to the second velocity; that takes multiplication not addition. 

Again, your argument places math above mechanics. Mechanics comes first! Acceleration in a straightline only REQUIRES a single dimensional variable, any others are extraneous and confusing when applied to the real mechanics.

Still waiting on you to explain the units of orbital velocity by the way...
