Aerodynamics of Diamond planform wings

[PujaSunil88]

Heya Everybody! I was searching for papers on the Aerodynamic characteristics of diamond wings, I mean detailed research papers/ literatures/ E-books...as a part of my assignment cum Thesis. Unfortunately, I could'nt find many. If anyone of you could please guide me as to where I will be able to find materials ( research papaers/literartures/ E-books/any related material), I would be extremely grateful.

Also, is there a method to find out the dynamic damping derivatives for an aircraft ( for eg: variation of Cm or Cn with respect to rate of change in - angle of attack, flight path angle,control surface deflection, or any other related parameter ) from static parameters( for eg" Cm or Cn obtained from wind tunnel results). I want to find out dynamic damping derivatives without actually measuring it from the wind tunnel...If there are literatures/ E-books or Research papers or anything related to the topic, please do let me know.

Here is a link to the AIAA website.

I just typed in "Diamond planform" into the Publication search engine and a couple of potentially useful references came up. If you can get a hold of those papers they will likely give you even more references.

@RandomGuy88: thanks a lot for the info.

Finding out dynamic derivatives is no easy task by any means and strictly speaking cannot be done analytically with any reliable accuracy. However there are methods to estimate them (use with caution). As far as e-books goes I have no idea, however the book "Flight Stability and Automatic Control" by Robert C. Nelson details one of these methods.

You could also try a vortex lattice method like Tornado.

It is capable of calculating stability derivatives.

Hey! thanks a lot both of you...
