this is what I've been trying to achieve with my bomb sight, but isn't really doing what it's supposed to. Can anyone help?
My variable expression so far :
g = 9.81
h = AltitudeAgl
v = TAS
t = sqrt( 2 * h / g)
phi = atan( h / (v * t))
input = phi/90
HingeRotator range is 90°
After modifications (still not functioning correctly.)
g = 9.81
h = AltitudeAgl
drag = 0.05
v = TAS
t_approx = sqrt( 2 * h / g)
t_impact = t_approx + (1 / drag) * (1 - exp(-drag * t_approx))
y = h - (g * t_impact) + (g / pow(drag, 2)) * (1 - exp(-drag * t_impact))
x = (v / drag) * (1 - exp(-drag * t_impact))
R = atan(y / x) /90
Input = R
HingeRotator range is 90° Detacthers are set to 0%
Sorry I tried with a different plane but it no work
@MizeaO yea the second set of expressions do. Acceleration being the gravitational acceleration. Since the Detacthers are set to 0%
@WizNick you mean whenits dropped
Its calculate by 3 variable?
acceleration velocity and drag?
Right?
@WNP78 Plz help identify what's wrong and why does not work.
@MizeaO found this statement on the comments section of an old mod: "bombs (after they have been dropped) have a different type of drag to SP's normal drag for some reason, instead of being SP's custom directional drag system they just have standard unity fixed drag (with a value of, if I remember correctly, 0.05). The way PhysX applies this drag is according to the internet via the per-frame formula
velocity = velocity * ( 1 - deltaTime * drag). That's a frame-by-frame process, but if you want to do it with continuous calculus then that can be rearranged to the forumlaacceleration = - drag * velocity(with drag being 0.05). Which I guess you can form a differential equation for or something" by WNP78. Would try to use this. Thanks for suggesting.@WizNick i think you should crake the SimplePlanes code to see how it work, or maybe calculate 1G=10m/s²? Im joking.
Your mathematics is correct.
@WizNick tag pls
This post accidentally became a teaser for my second car build. Didn't expect that the paper would be so thin. Can barely see the car silhouette
I might have something that could help. But i have to put it together first.
