The Pyramid, a TRPT rethink

I will provide the presentation in PowerPoint format Google Präsentationen wird geladen

Also, the simulator at GitHub - tallakt/TRPTSim

And an in depth document at the same github repository at https://github.com/tallakt/TRPTSim/raw/main/docs/the_pyramid.pdf

I’d also like to mention a “hidden gem” being my improved though still simplified tether drag model described at https://github.com/tallakt/TRPTSim/raw/main/docs/a_simplified_drag_estimate_for_a_tether_with_a_belly.pdf

Ha ha
Just seen my membership has been changed to
Accredited Academic
:joy:
If you get to watch me fumble my way through this presentation you’ll see that’s not really the case

Well what can you expect, when the accreditation agency is me? :crazy_face:
It’s about access. Behave and you can keep it. :rofl:

I was asked a question after the presentation … something like
What is the proportion of line drag relative to the system?

I didn’t have much of an answer… but we can get some idea by comparing this mechanical drag system to the Makani report data set.
Negative issue - this tether would be travelling through more area as it terminates at a rotating truncated pyramid … not a point connection to the ground station as Makani.

Positive Issues - this tether would be thinner, as it doesn’t have electrical conductors. The craft would also be significantly lighter (higher efficiency AWES) without the generators, controllers, electrical gear, turbines (and their drag), propellers… so the tether could be thinner again
