How does the accelerometer calculate component turn angles? (yaw, pitch) One first then the other? Or both simultaneously? [closed]
This question is not specific to a particular engineering architecture. But I am hoping that most aircraft are designed in the same way.
When the aircraft yaws and pitches at the same time, which ...

What on Earth is Going on with NASA's PRANDTL-3 Wingtips?
I'm afraid this will require some explanation. I'm sorry, this will be a long read but I hope it's an interesting conundrum. If anyone reading this isn't familiar with NASA's PRANDTL wing research, Al ...

What causes the secondary effect of rudder, and which direction does it act?
I understand that rudder deflection causes several things to happen. Primarily the aircraft yaws, and for a positive (trailing edge left) rudder deflection there will be a positive side force ...

Does the CH-47 Chinook generate differential yaw as a side effect of generating differential lift?
I have been reading up on the controls of the CH-47 Chinook. I understand how yaw movement is created not by counter torque but by opposite cyclic on the front and back rotors. What I'm wondering ...

How does the Sikorsky Defiant X make yaw as it has no-tail rotor? [duplicate]
That picture I took from here. To understand my question I suggest you to watch it just 10s, just very short, but it will show you very closely when that Sikorsky make yaw. As it is no tail rotor like ...

Why does this V-22's rotors rotate clockwise and anti-clockwise (the right and the left rotor respectively)?
Picture source:
By seeing the blades, we know the rotation's directions. The right side is clockwise and the left side is anti-clockwise. Both seen from the pilot/rear side. During the cruise, the ...

how does the lilium jet counter asymmetric thrust?
So Lilium states that its jet is a tailless design. Now, you can see that it has engines on both sides of the centerline.
Lets imagine that all of the engines on one side fail, how does it counter ...

Why do most canards have swept wings?
So most canards have swept back wings. Now I have been told that it is that way to ensure yaw stability (for example in a crosswind) - not sure though.
But then I look at the new Lilium jet, which is ...

Why does static directional stability decrease with altitude?
At constant CAS, high altitude means lower air density and therefore higher TAS: this decreases the aerodynamic damping during a rotation.
For this reason, I cannot understand why directional ...

Why do some planes drift to the left in flight simulators?
In different flight sims I've experienced the same effect on certain planes: when accelerating on the runway, the plane drifts to the left as if the rudder was set to yaw left. You can counter this by ...

Calculating forces on a hexacopter which create yaw
I'm trying to design a mathematical model of a hexacopter, and while researching the mechanics of the object I could not figure out how to calculate the total torque on the drone in 'Z' axis that ...

Do pusher propellers create the same yawing moment as puller propellers? [closed]
We know that the effect of P-factor on puller propellers is the yawing moment in the opposite direction. I mean if we had a load (thrust or lift) on the right side of propeller, then the airplane will ...

How much does the fuselage of an airplane contribute to yaw stabilization?
Obviously considering that (almost) every plane has a vertical stabilizer, probably not, but for a relatively long aircraft does the fuselage measurably contribute to the yaw stabilization relative to ...

What is the influence of yaw on P-factor?
From William Kershner's “The Advanced Pilot’s Flight Manual”- page 2-17, P-Factor:
If the airplane is yawed, the P-factor effect is encountered. A left
yaw would mean a slight nose down tendency and ...
