Aerodynamic efficiency and static longitudinal stability

AI Thread Summary
Research on aerodynamic efficiency and static longitudinal stability often focuses on their interrelation, particularly in the context of "Trim Drag." The optimal center of gravity (CG) position is crucial, ideally at the neutral point to ensure the tail provides pitch stability without generating lift. Sailplanes exemplify this balance, as their CG is slightly forward of the neutral point, allowing for effective pilot control. High pitch damping is also an important factor in enhancing stability. Understanding these dynamics is essential for improving aircraft design and performance.

Hello,

I am looking for research results, report etc. dealing with
-aerodynamic efficiency and static longitudinal stability-
Couldn´t find anything useful yet!

Any ideas would be very much appreciated.
Best Regards,
granby

What exactly do you mean? Do you want reports dealing with either aerodynamic efficiency OR static longitudinal stability? Or a report with aerodynamic efficiency as it relates to static longitudinal stability?
 
How both factors are related to each other!
 
usually called "Trim Drag"...

the sweet spot is for the CG to be at the neutral point so that tail is making no lift.. but providing pitch stability through an active system (SAS)

a sailplane is a good example... the CG is just enough fwd of the neutral point that a pilot can control the plane... high pitch damping helps...
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
