Robert Steinke of SpeedUp has posted a new update, building a Mach breaker rocket
I’m starting on an extra little side project. I’m going to build a Mach-breaker rocket using the Cesaroni 29mm H410 Vmax motor. Here’s a picture of the basic layout.
I imagine the fist question I’m going to get is, “Why did you choose tube fins? Tube fins are high drag. Don’t you need low drag for a Mach-breaker?”
Worth a read for those interested in the physics of it all.
