Design of orientation mechanism for probe

http://en.wikipedia.org/wiki/Flight_dynamics

If you look at the different terms for each movement, you can visualise the mechanical way to achieve this movement. Now apply this to your field of interest or expertise and Bob is your uncle.

If you want a better explanation you need to offer a better question, sorry.

Before answering your questions i would very much like to know a bit more about the organization of the laboratory where you work.

It is for me very surprising that you have to ask for our support knowing how high is usually the level of person dealing with fluid research in aeronautics.

Who are you ? What is your job and how is build up the team you work in or with?

Who are the other team members? Their degree ?

I have contacts with laboratories doing same work as you claim to do and if they require help (that means they place orders) it is only for very special items as complex transducers or acquisition equipment for complex research but never for such trivial problems which they are able to solve by themselves.

Please explain me where the differences come.

Again before giving you any suggestion i only want to say that the input is quite unsatisfactory since you do not give any indication about model dimensions, Mach number, what you want to measure pressures only, forces, moments ? How big you estimate them?

Do you want to use a programmable support or one you set between tests?

As you see there are a lot of questions to answer before any idea can be suggested.

Have you found the flaw?

Is this for Del's sketch of the scannivalve?

You can have small slots or dimples in the base with a spring loaded ball in the moving part. This should give you a positive click stop.

The ball can be replaced by a spring with a V fold at the end.

A alternative could be 20 tri state sliding valves (have a look at the valves used in a trumpet and expand on the design)
