I meant 3rd, sorry.

Cyrus, i used the equations in your first reply because the manufacturer provided me with the related data. attached is an output for Thrust vs Velocity, it seems pretty reasonable to me.

" WARSAW, Poland — Poland and the United States struck a deal Thursday that will strengthen military ties and put an American missile interceptor base in Poland, a plan that has infuriated Moscow and sparked fears in Europe of a new arms race. "...

Thank you for your reply, the information has been very helpful, I've also received some additional data from the prop manufacturer that i can use as a sanity check.

Yes i found a good chapter in the following book describing what i wanted: Propeller Theory and Applications in the book "Airplane Aerodynamics and Performance" (Roskam) The problem is that the geometry of the propeller and in particular the integrated design lift coefficient ( CLi) and...

Thanks for your response, One of the websites you listed had the following graph: http://www.epi-eng.com/images/Redrives/PropEff-01.gif which is EXACTLY what i am looking for. However i need to know how to generate something like this mathematically using my own horsepower, rpm, and...

The following are a few questions that i have come across while writing takeoff distance code: 1. Assuming a known static thrust, how will this thrust vary as the airspeed increases? ex. Is the relationship linear? quadratic? how can i determine the coefficients of the "thrust in terms of...

Alright thanks. So i gather that if we considered an area of a wing section; -if the static pressure > dynamic pressure , the particles collide more often (the fluid is denser) and with smaller force(the momentum is smaller) -relative to the condition where: -the static pressure < dynamic...

" So it doesn't involve the air 'crashing' into the surface of the airfoil. " I thought that pressure by definition is the 'crashing' into the surface, otherwise how else could it impart a force? Secondly, I understand the conservation law and how it works, I am just wondering what makes it...

Thanks a lot, that was very helpful

I am having trouble relating the two quantities of dynamics and static pressure in: 1/2p*v^2 + p = constant, bernoullis equation, to corresponding physical descriptions. In what way do the air molecules act to create both dynamic and static pressure, respectivley? As far as i know, dynamic...

So i will never come across: topology, number theory, abstract algebra, group theory, order theory, topology, fractals, chaos, logic, set theory, category theory, graph theory, combinatronics or any others beyond the above mention? Also, specifically what type of algebra?

I'm just beginning to study aerodynamics, and i was wondering if anyone could list the topics, fields, and types of math that are used in textbooks, research papers, journals etc. that one would read when studying aerodynamics?

I am an aerospace engineering sophomore, and i am interested in double majoring or minoring in a related field. Some minors/double majors i am considering include: Green Engineering, Ocean Engineering Math, perhaps Applied and Computational Mathematics Physics I'm not really sure what...
