Black Rock Blastoff of the Green Planet 🚀
Summary
[edit]
| Description |
English: Black Rock Blastoff of the Green Planet 🚀: The mystery of my supersonic-shred overhead, solved today (in comments below).
From my photos, the upper half of the rocket disintegrated 2.1 seconds after launch. The Cesaroni Aerospace K454 motor (from Canada) provided 139 lbs. of peak thrust to a 3-lb airframe, built from a lightweight composite mortar shell tube. I ran a pre-flight RockSim flight simulation that shows it pulling 20 g's as it leaps from 0 to 946 MPH. It has a fiberglass and aluminum nose cone (plenty strong for this flight) and a HD 808 key fob camera in custom 3D-printed holder, which lost the camera on the supersonic climb (I know how to secure it next time). So.... last photo has the diagnosis. |
