New Years Fireworks
Quick Update here. First, I'd like to show you the latest test firing we performed:
This was our best firing of our 3" motor to date! Our two-stage test utilized two different feed lines, starting off with a low oxidizer flow rate and then switching over to a high oxidizer flow rate. You can see the difference in thrust when the switch happens halfway through the video! We've maxed out the oxidizer flow rate we can achieve using a 50lb nitrous bottle.
For our next firing, we're going to:
- Replace the external SS nozzle with an internal graphite nozzle.
- Test out some thermal protect applicators to the head the motor.
- Streamline the plumbing on the injector side to move the pressure transducer closer to the pre-combustion chamber.
We've also started work on designing our 10" Motor Test Stand. Here's a preliminary mockup:
The test stand is going to drawn up in AutoDesk (a Computer Aided Drawing program) and force-tested using ANSYS (a computer-aided engineering program), then we'll start building the platform.
My goal is to provide you an end-of-January update with another test fire video, more work on the 10" test stand, a couple of screenshots of the Hermes in AutoDesk, and some pictures of the 10" motor being built.
I hope you're as excited as I am about all of the work being done! Thank you for your continued support!
