Ever wondered why your altitude predictions in your software don't match your actual flights? The secret might be hiding in your drag coefficient!
I'm excited to share my brand-new step-by-step video tutorial that transforms those mysterious CSV files from your flight computer into valuable performance data. This follows the approach presented in Peak-of-Flight Newsletter #561 (apogeerockets.com/Peak-of-Flight/Newsletter651).
Introducing “No-Math Drag Coefficient Magic”—a brand-new video that turns your accelerometer logs into actionable insights, without a single equation.
Here’s what you’ll get:
Click-and-go guidance: Follow along as we break down the process using real flight data (spoiler: it’s easier than prepping ejection charges).
Free spreadsheet template: Plug in your numbers, and let the formulas do the work.
Pro tips: Learn how to spot coast phases, avoid common mistakes, and interpret your Cd like a seasoned engineer.
Real-world example: Watch us calculate the Cd for a 41mm diameter rocket live—and see why it’s a game-changer for altitude predictions.
No calculus. No guesswork. Just 8 minutes between you and a sharper, smarter rocket sim.
Watch now and demystify your drag
P.S. Grab your last flight log before hitting play—you’ll want to crunch your rocket’s numbers before the credits roll!
