Aircraft Loading (BENDING AND SHEAR DIAGRAMS)

Postby IMAN » Sat Jul 18, 2020 6:24 pm

Hello,
Could you please help me with finding a sample program code to determine shear and bending moment for aircraft under different flight conditions?
Sample results are reported in the book by Denis Howe.
Aircraft Loading and Structural Layout
Thanks
Best Regards,

Hi,

mechanical engineer here - what exactly are you looking for? I think the possibility that someone has the book you reference on hand is rather slim. So maybe you can provide some more info about the problem: what is given and what results are you looking for (plot of force/moment vs what)? In this general way it could be anything from a simple analytical code up to industry grade FEA that's needed to get the results you need.

Also - is this for school/university/homework? Or relevant for using/developing flightgear?

Cheers,
Daniel

Thanks,
Here it is not possible to attach a file for more details. Firstly, input data are mass and other info about aircraft to be able to plot and compute shear and moment diagrams vs the length of the aircraft.
As you know some softwre such as FAR23 are able to do this. This is a work that I intersted in working on myself.
If you need more info please give me your email or send me an email.
Best.

I take it you mean "FAR 23 Loads" by DARCorporation? This is what I referred to as industry grade software ;-)

I would take a look at the very good book series by Jan Roskam: Airplane Design. They are rather old but still very relevant and used in airplane design. And the good thing about being old is that they explain the manual way to estimate and calculate stuff from empirical charts and formula. I will take a look in the ones I own, if there's something relevant for your problem in there.

Thanks,
Exactly. My mean was FAR23 Loads.
So, i will be waiting to receive your response.

Hi,

sorry - none of my Roskam Books has anything on that topic. From the Table of Contets I'd expect Part III to be the relevant one. Maybe you can check it out in a library or online preview before buying?
