Designing Helicopters or any particular engineering what math's are evolved?...
...Besides physics? Which is more appluaded? (Algebra, Geo, calc.)Which is more used, and what maths are envolved? Do you have to be an Astudent to be an Engineer?

LOLAll of them!LEARN ALL YOU CAN. THEY ARE ALL INTERRELATED.They are not completely independent fields of study.You will conbine calculus and algebra and various other aspects of math depending on each particular situation.

Aeronautical Engineering includes "Helicopters" and all forms of aircraft that move through a fluid.Most math involved would be: calculus, multivariable calculus, differential equationsnumerical computing methods.As for sciences you can expect (on top of general physics): static and dynamic ****ysis', dynamic fluid flow including subsonic, transonic, sonic and hyper sonic flowMaterial scienceThis is a start (advanced courses you have to choose a concentration). You don't have to be a great student to succeed in engineering, but you do have to be really interested in the material to have a chance to succeed. Again this only applies to Aeronautical Engineering. Each Engineering discipline is unique in its curriculum.

Calculus is probably fundamental for a ton of engineering disciplines. Algebra is needed to solve many calculus problems too. Geometry you will need some of. In college you will also really need Linear Algebra, differential equations and Probability Theory.You don't have to be an A student now but you probably need to start getting better study habits and spend more time studying for your math. So if you basically get math but are having a little trouble you can still make it up through hard work.However, if you are a person that doesn't get math no matter how hard you try, then Engineering is not a good path for you. Hope that helps.

It depends on how much involved you are in the designing. The rotor blade would be an interesting example. During one rotation, the blade will be moving (let us say the tip is over the tail boom and rotating CCW)First 180 degrees (till the tip is directly ahead of the helo) it will have the combined speed of the helo's forward motion and its own rotational velocity. In the next 180 degrees it is the rotational speed minus the aircraft's forward velocity (as the blade is moving in the direction opposit that of the helo). So if the blade has same angle of attack, the lift it produces will be different in these two halfs. You will need serious math to calculate these forces and to correct the blade angles so that the net lift acts through the rotor shaft.You bet all that you can think of will be used if you go to such design depths. Academics is a measure, but aptitude and correct applications can balance academic shortcomings.So the answers, math is involved. Algebra and calculus are most probably required and you need not be an Astudent for all that. Orville or Wilbur never were ....
