Angular Misalignment Requirement: Vector Sum of N deg - Brian

[bcarlson]

I have document that list different technical requirements on a project I'm working on.

One requirement is on initial angular misalignment.

It states:

Vector sum of N deg about X and Y axes.

Does this simply mean that the:

sqrt(Theta_X^2 + Theta_Y^2) = Theta_Total < N

Or is there something more complex going on here?

Thanks in advance.

Vector sum of N deg about X and Y axes.

This looks like an incomplete sentence. Could you elaborate?

Its an excerpt from a table of requirements. The entire table entry for relative "Angular Missalignment" between two frames A and B consists of the two following requirements.

1.) They allow 3.0 degrees of angular missalignment about the Z axis.

2.) The also require that the vector sum of the individual missalignments on the X and Y axes be limited to 3.0 degrees.

Thanks,

Brian

My interpretation of what the requirement means is the same as yours.
