View Full Version : What mathematical formula best sums up aviation?

A dreary Wednesday afternoon's off-topic discussion about the "most beautiful" mathematical equations (and the world's most beautiful mathematician, Rachel Riley, but that's really getting off topic ...:E ) led to the following question: what formula most elegantly encapsulates aviation today?

Candidates so far, in no particular order, are:

(1) Lift Coefficient for the engineers: without it (them?) we'd never have got off the ground

(2) The (second) Fundamental Theorem of Calculus: so our pilots always know where they are or when/if they're going to get to where they're going.

(3) Eurocontrol's charging formula: keeping the world from descending into chaos, or at least the bit that calls itself European, and management picks up the cost.

Any other propositions?

Surely the ONE and ONLY formula that encapsulates the whole of aviation for which, without it, aviation would cease to exist, is:

L = (1/2) d v2 s CL :rolleyes:

But the "rho" is upside down.

And it's not v2, it's V squared.

Lift Pressure divided by q = what ?

guesss- wing loading?

Lightning Mate

Nope..........

That's weight + tailplane downforce divided by wing area.

What equation sums up aviation?

Cb = 1/2p v2 S

Cb = Coefficient of bonuses (CEO and exec)
p = current pilot salaries
v2 = true speed of reduction in pilot pension plans
S = bean counters per cubic foot of Co office space

Sensible answer - F = ma

or

happiness = [(velocity/height + max 'g') x hours - bullshit^2 - niff-naff-&-trivia] between the limits of medical cat. and luck, and negative infinity outside these limits.

We all know that the lift of a wing is 1/2 ρ V2 S Cl. Obviously the lift of the other wing is also 1/2 ρ V2 S Cl, so that the total lift is ρ V2 S Cl. It follows then, that the lift of a bi-plane wing is 1/4 ρ V2 S Cl, and the lift of a wing on a triplane is 1/6 ρ V2 S Cl.

For a (very brief) moment, I thought of posting this under Questions thinking I'd get some serious tech answers ... but all of the above are much more interesting. :ok:

Lighning if you don't define your terms all abstract mathematics is nothing but a jumble of letters.
