Propellers Design

[Bruno Marques]

Hi, I am currently modelling a Tecnam P2006T and I want to do an aerodynamic simulation of the whole aircraft icluding the slipstream effect created by the two propellers. I already imported the aircraft without the propellers from SUAVE to OpenVSP. Is there any tutorial available about how to create propellers in OpenVSP?

No tutorial that I know of.

If you're going to use VSPAERO, then you don't actually need to model
the propellers in detail. Instead, just add 'disk' components and
match their location/orientation/diameter to your props. Then, set
the RPM, CT, CP and whatnot in the VSPAERO GUI and go from there.

If you are using some other tool, that models the blades of the prop
in detail, you will want to use the Propeller component. OpenVSP has
the ability to import/export a generic blade element type file. So,
you can use your favorite BEM code to design a prop -- convert the
file -- and then read it into OpenVSP, creating a propeller component.
Or, you can design a prop in OpenVSP and then dump out a BEM file for
analysis in your favorite code.

Hi Rob,

Thanks for the help. For now I think I am going to design the propellers as disks and then use VSPAERO to set  the RPM, CT, CP just to get the hand of it. However, my final goal is to design them in SUAVE and then import them to OpenVSP and just have to use VSPAERO for the aerodynamics analysis without having to design any extra components in OpenVSP.

Kind regards,

Bruno

hi rob

how to Define the propeller as disc for pusher or puller?

[Rob McDonald]

The Disk component doesn't care -- it is just an actuator disk that
you locate in your model and then specify RPM, CT, CP, etc.
