How to account for propeller (fixed pitch) in model aircraft performance calculations?
I'm working on performance calculations for a plane I'm building. By setting the sum of my drag formulas (one for the wing, one for the fuselage, both with predicted drag coefficients) equal to the ...

Are there any formulas for acceleration to max speed time/distance
I'm working on optimization code for a RC Plane competition.
I'm trying to figure out both the distance and the time between when the plane takes off and when it reaches max speed. I already have ...

How to couple panel method velocities with boundary layer equations to obtain viscous pressure and lift coefficient?
I have calculated CP(pressure coefficient) and CL(Lift coefficient) for a NACA2412 airfoil using the panel method but as it only allows us to calculate the same for inviscid flow, I could not get the ...

Question about Mars Ingenuity helicopter's wide-chord blades
I marveled at the two flight videos today on YouTube by Perseverance helicopter flights during Ingenuity mission.
Got me thinking.
Why aren’t the helicopter blades wider? I would like to think that in ...

How do aerodynamics for small model aircraft differ from that of larger aircraft?
I am reading an aerodynamics textbook (Introduction to Aerodynamics by Anderson). I am still in the chapters that deal with subsonic aerodynamics, which seems to have a focus on life-sized manned ...

How do thrust requirements change as a multirotor leaves ground effect?
Assuming either a quadcopter or a hexacopter, is there any published data on how much more energy is expended to escape the ground effect?
Is it a function of the thrust being produced to lift the ...
