Anduril Industries achieves breakthrough with Denali hypersonic rocket booster test

Anduril Rocket Motor Systems has announced the successful static test firing of its Denali 18-inch hypersonic booster.

Just once I wish I had something cold-launched, that leaps out of its canister with a weighty _FOOMP_ that resonates in my chest cavity, and then hangs in the air threatening not to ignite right up until I'm about to lose my nerve and flinch. And then I wish my cold-launched angel would spread its wings and fill the sky with iridescent white fire so pure it blinds us all for a moment, as it streaks impossibly fast out of sight, toward some terrible purpose.

This was the first rocket motor that I had ever tried to build. Inspired by YouTube videos, I constructed it out of PVC pipe and some stacked washers for a nozzle. The fuel was made from “rcandy” which is nothing more than sugar and stump remover. Some stump removers (maybe not anymore) contain KNO3; an oxidizer. I cooked it up in the garage on my dad’s old hot plate that he uses to etch circuit boards (heat is a catalyst for dissolving the copper). The problem with this method is that what you end up getting is a thick, sticky, HOT, paste that has to be packed down inside the motor tube. This leaves the potential for air pockets, and painful burns. When the fuel cooled, I drilled a hole down the center to make room for the gas to flow and a place for the igniter. I had wanted to build a rocket for it, but my dad convinced me to test it first. I think I rigged up the entire test bed on Thanksgiving day. It consisted of a bathroom scale, boards nailed together to hold the motor upside down, and a couple of old cameras pointing at the meter. If you’ve already watched the video by now, you know that it explodes. But the video does not do the noise justice, it was by far the loudest thing I had ever heard. The neighbors across the street came out to see just what the hell was going on, and most likely curious to why the world was ending on Thanksgiving day.

NASA Prepares New Sounding Rocket Motor For First Test Firing

Huntsville AL (SPX) Feb 10, 2015 NASA engineers are preparing a new Peregrine sounding rocket motor for its first hot-fire test set for February 10 in the east test area at NASA's Marshall Space Flight Center in Huntsville, Alabama. The Peregrine sounding rocket motor started as a NASA Engineering and Safety Center (NESC) project and was designed in-house by NASA engineers, but was built in cooperation with commercial sup Full article
