Since posting my initial "Propeller Static & Dynamic Thrust Calculation" post, I have had many questions about where this equation comes from, and several requests to explain more.  I have even had college students ask me about the equation.  Additionally, this is my most popular post at the moment and is getting over 700 views per month, with the bulk of those hits being from Google Search results about propeller thrust.  So, I think it's time I explain more about the background of the equation.  Here goes.

First off, here's the nomenclature I will use:

Aim High

Aim high!  Shoot for the stars and you’ll land on the moon; shoot for the moon and you’ll land on the roof; shoot for the roof and you’ll land in the dumpster. Aim high!

I've heard quotes similar to this, and the other day (22 March 2014) I thought about this and wrote it on the top of a to-do list I had which pertains to Unmanned Aerial Systems-related projects I'm working on.  These are the types of things I try to remind myself regularly.  Aim high.

The Goal of a Lifetime

What are My Limits?




"It should be the end goal of any professional to reach such a high level of skill at what you do that you are no longer limited by your abilities; but rather, you are limited only by your imagination."

"Reach your true potential."
~Gabriel Staples, 20 July 2020

I was inspired with this thought tonight while listening to this song (Fear Not This Night (ft. Asja)), followed by this song (David Guetta - Titanium ft. Sia).  As the second song finished, I thought to myself, “did you hear any flaw in her voice?...are there any notes she cannot reach?...does she not have a perfect mastery of music?”  And then it hit me, musical artists at this level are not limited by their skillset, or the lack thereof; they are not limited by vocal control, or a sparse understanding of music, beat, rhythm, and notes.  Rather, singers like this are so skilled that they are limited, in what they will accomplish in their music, only by their imagination.  So it must be with engineers.  In the world of engineers, hobbyists, users and creators of electronics, RC pilots, systems and electronics integration experts and inventors, mathematicians, we must become so adept in our fields that the only limiting factor in what we can create in our areas of expertise is our imaginations.  Let us resolve to better learn our fields, and to make personal efforts to improve our skills on a daily basis, so that we can become doers and not just hearers in whatever we do.  "Be a Thinker, and Be a Doer," that is what drives me [1].

In regards to my professional interests, my goal is to become so skilled in Unmanned Aerial Systems, electronics, aviation, and computer programming, that nothing can hold me back from developing whatever I want to on the leading edge of technology, stretching the bounds of our world as we know it today.
