.vsp3 file of openvsp for PROWIM wing geometry

[Bonifaz Bryant]

Hi Emilio,

I have read your paper "Aerodynamic Verification and Validation of SUAVE" where SUAVE is used to validate the aerodynamic characteristic of PROWIM wing geometry. I would like to ask if you could share an Openvsp file of your PROWIM model (.vsp3 maybe).

 Because I haven't been able to find this file anywhere else.

Many thankns,

Hi Bonifaz,

The PROWIM wing model shown here was recreated in SUAVE using information from Veldhuis' thesis (ref 18 in our paper). I don't have a .vsp3 file of it, but if you want to recreate the model in SUAVE you can export to OpenVSP using vsp_write.py located in the Input/Output directory in SUAVE (or just build directly in openVSP). The wing itself is a very simple rectangular geometry (defined in the table or in the reference paper), and uses a NACA 64-A015 airfoil. 

Best,

Racheal

Hi Racheal,

Thank you very much for your reply, as you said, I can find some geometry parameters about PROWIM in Veldhuis' thesis(As shown below）. I can easily draw PROWIM wing in Openvsp based on existing parameters (such as airfoil, chord, wingspan, etc.). But I still don't know the specific parameters of the nacelle and the propeller (such as the CT and CP of the propeller), so I still can't completely re-implement the aerodynamic simulation calculation for PROWIM. Thus, I want to ask if you can share your SUAVE code on PROWIM with me, I want to achieve the perfect result in your paper through this.Thanks in advance！

Hi Bonifaz,

In the SUAVE verification/validation paper you cited, we only compared the clean-wing test case. For a different paper we did run the props on case. For this, we also just followed the provided data in Veldhuis's thesis to obtain a propeller with the appropriate radius and the thrust coefficient for the given operating conditions that was provided in the thesis. This was done using the propeller_design.py script to obtain a minimal induced loss propeller geometry that matched the conditions and thrust coefficient provided. As for the nacelle, again we just followed the provided geometry to approximate the size (as you show in the figure above, the nacelle diameter is provided). I don't have that file easily accessible, but it should be pretty straightforward to recreate.

Best,

Racheal

Hi  Racheal,

Thank you very much, I have tried to model with the dimensions provided by Veldhuis's thesis. grateful! 

Also, I would want to ask if you can share your SUAVE code on PROWIM with me, I want to achieve the perfect result in your paper through this. Thanks in advance!

Many thankns,

Hi Racheal

i'm very appreciate to read your paper

As I understood, you ran the validation of Veldhuis's PROWIM without propeller geometry(i.g. chord length, blade angle distribution).

It is understood that the propeller was reverse designed by the given Ct, Cp.

Is It right ?

Im validating PROWIM Model using OpenVSP, and I also couldnt find detailed Ct, Cp on Veldhuis paper.

So I found propeller 5868-9's Ct, Cp by the given advanced ratio. [P. Hartman and D. Biermann, “Static Thrust and Power Characteristics of Six Full-Scale Propeller,” NACA-TR-684, 1940]

Finally I guess Ct, Cp by the given J, Ct=0.095 and Cp=0.097.

Is same value on yout reverse designed of propeller ?

Thank you for reading it.

Hi Seo,

Do you have a PROWIM vsp model?

Could you please share your PROWIM.vps file with me? Thank you in advance!
