Rocketry Acronyms
The last time I was into rocketry was almost 30 years ago. I've been back as a BAR for a few months now and, ofcourse, in this internet age I have to look around online for all things rocketry.
One thing that I found a little difficult reading Forums and Blogs was figuring out what all the acronyms stood for!

I wondered if this might be difficult for other noobs/newbies (and oldbie returnee's) so I kept a list of the acronyms that I encountered along the way.
These I list below as a reference for anyone that may need them.
Only those frequently encountered on forums are listed.

I hope someone finds these useful.
If it helps only one person, it was worth it.

Edit: Corrections & contributions from members. Thanks!

This is by no means an exhaustive list, there are very likely many other acronyms missing from the list.
Fortunately, Rocketry Center forum appears to allow perpetual editing of threads/posts, so I will update and make corrections as I (or you) find them.

If you have a suggestion or contribution, please post in the Rocketry Acronym suggestions thread.
Please note: Club acronyms have been deliberately left out, if you can't find an acronym here, please check the Rocketry Club Directory thread.
