Brevis & Vendan | Character dialogue

Brevis

Vendan, I’ve been crunching the latest load‑bearing composite specs for our next combat drone. Could you run me through how you’d tweak the armature for maximum thrust while keeping the weight under twelve kilos?

Vendan

Sure thing. First cut the armature’s mass by swapping the heavy steel ribs for aluminum alloy—gets you about 1.2 kilos off. Next, re‑engineer the gear ratios so the motor turns higher speed but still in the 10‑kW range; that boosts thrust without a weight hit. Add a lightweight composite shroud around the propellers—just a few centimeters of carbon fiber, and you’ll cut drag and keep the extra weight to under 0.5 kilos. Finally, use a modular battery pack that plugs straight into the armature, so you can swap a heavier pack for extra burn time when you need it. All in all, you’re looking at roughly 11 kilos with a nice thrust boost.

Brevis

Nice work on the mass savings. Just make sure the aluminum ribs still meet the stress threshold under dynamic loads—tensile testing at 2000 MPa is a good benchmark. Also, double‑check the modular battery interface; we’ll need a quick‑disconnect feature so swapping takes under a minute. If we can shave another 0.2 kg off the shroud without compromising stiffness, we’ll hit that 10.8‑kg sweet spot. Ready to move to the prototype phase?

Vendan

Yeah, I’m ready. Let’s crank out the prototype and test that shroud in the wind tunnel.

Brevis

Great, let’s hit the design board. Draft the new shroud CAD model first, then schedule the wind‑tunnel run. I’ll run the CFD check to confirm the drag reduction before we cut any material. Keep the timeline tight—every hour counts.We are done.Great, let’s hit the design board. Draft the new shroud CAD model first, then schedule the wind‑tunnel run.

Vendan

Got it, drafting the shroud now. Will lock in a 3‑hour window for the wind tunnel after your CFD review—no slacking on the schedule.

Brevis

Copy that, Vendan. I’ll finish the CFD in an hour and lock the wind‑tunnel slot. Make sure the rig’s set up—no room for last‑minute fixes. Let’s keep the timeline tight and hit the target.

Vendan

All set, rig’s prepped. I’ll double‑check the fitments right before you lock the slot. Tight as ever.
