I build liquid rockets, but whenever there is a liquid rocket out at the Friends of Amateur Rocketry, chances are I'll be there helping, filming, getting in the way, or generally hovering.
Half Cat Launches Too Many Rockets
I recommend setting the video to 4K on a 1080p monitor
January to May 2024
It's been a while since I've been able to upload a video, but that hasn't stopped Half Cat Rocketry from testing their new Mojave Sphinx. The Mojave Sphinx is result of years of steady testing to create a simple and robust Nitrous-Anything rocket. Alongside it's consistent performance and high reliability record, this has also been the best documented Half Cat Rocket to date, and has already set the standard for entry level bipropellant rocketry.

November 4, 2023 Finally getting through the video backlog of 2023. Things are extremely busy behind the scenes at FAR, with new construction and the second annual Academic Industry Liquid Rocket Symposium happening on January 27. This day, Kip Daugirdas returned with Mesos for a revenge flight, following a previous attempt in May. With Kip's high performance rockets, and higher waivers and imp...
A Closer Look at Half Cat Rocketry's Mojave Sphinx
มุมมอง 9406 หลายเดือนก่อน
November 4, 2023 It can be difficult to see much happening at the bottom of a Half Cat nitrous alcohol rocket in flight. The clear burning combustion is essentially invisible, so all you hear is the buzz of the motor and the dust kick up off the ground. After having skipped the static fire process for 1CAT/4 and most of the Mojave Sphinx, the Half Cat team are going back to collect some importa...

October 7, 2023 Space Enterprise at Berkeley, who have been covered extensively by this channel over the few years of their meteoric rise to prominence in collegiate liquid rocketry, have achieved the milestone of vectoring or gimballing a liquid rocket motor. And not just some boilerplate either, but a flight weight full duration 15 second static fire. This means that they have set the world r...
New Motor, New Attempt at Recovery and Broadcast Testing (Space Enterprise at Berkeley)
มุมมอง 5737 หลายเดือนก่อน
October 7, 2023 Three weeks ago, the Berkeley team attempted to flight test their recovery system for their liquid bipropellant rocket. While matching the profile and materials of the liquid rocket as best as they can, which includes strong MJF 3D printed components and fiberglass, they use a simpler Aerotech commercial motor as their motive force. In their first attempt, the nozzle blew out, a...
Testing Recovery Systems for a Liquid Rocket (With a satisfying conclusion)
มุมมอง 1.1K8 หลายเดือนก่อน
September 16, 2023 Space Enterprise at Berkeley is starting to pick up speed again with the new semester. They have a long list of objectives to accomplish. While one part of the team focuses on testing the vertical stacked liquid bipropellant rocket, another part focuses on testing the recovery system on a subscale vehicle. With a commercial off-the-shelf motor, it's almost certain to achieve ...
First Person View of Operating a Liquid Rocket Engine

September 9, 2023 You have to make tradeoffs when performing a liquid rocket static test. The last time we tested this motor, I had my cameras rolling, but we forgot to start recording the data acquisition (DAQ) which would record our test data. This time, in order to make sure the DAQ was recording, I had to forget to start most of my cameras. This time, however, I had a camera on my helmet to...
Filming a Rocket Motor Through a Sugary Snowstorm (Paul Snow)
มุมมอง 8978 หลายเดือนก่อน
September 9, 2023 Filming Sugar Rockets is a risky and often unfruitful business. These motors love to eject enormous clouds of matter, assuming they don't explode from one of many failure modes common to sugar propellant. Normally I wouldn't risk putting my cameras so close to one, especially not my latest and most expensive 4K camera. I made an exception for Paul Snow's latest motor though, a...
Parachute at Take Off (Oregon State University)

August 19, 2023 With a tropical storm looming over the horizon, Oregon State University pushed forward with their launch plans, and found the weather cool and inviting out in the Mojave Desert, with relatively clear skies and calm winds. In 12 hours, the entire desert would become inundated with uncharacteristically high rainfall which would see the roads close and the dry lakes fill with water...

August 5, 2023 A short and simple video, as activity has quieted down briefly with the new academic year looming. With a 4K drone, 4K camcorder, 4K gopros, and now a newer high speed 4K gopro, I have all the tools I need to capture any angle in as high a quality as I want to (including from in front of the nozzle, but that's only on rare occasions). For the 1080 viewer, this translates to bette...
The Mighty LOX Hybrid Rocket of Bavaria
มุมมอง 1.7K9 หลายเดือนก่อน
July 15, 2023 Unlike other rockets from the continental US, international rocket groups need to contend with customs and shipping. The same process applied to the EX-3, the LOX-HTPB hybrid rocket developed by WARR, from the Technical University of Munich in Germany. EX-3 exists on the upper end of the "Q" motor impulse classification, with more than 3 times the energy of the typical bipropellan...
Powerful High Performance Rocket Explosion and Impact (Aerobing)
มุมมอง 2K9 หลายเดือนก่อน
July 16, 2023 With high performance solid rocket motors, the likelihood of catastrophic failure increases as the pressures and stresses edge closer to their ultimate limits. The high heat of the desert summer makes these margins ever lower as both propellant and resins soften, and focus wanes. With appropriate safety installations like FAR bunkers, a motor cato may be best placed just after it ...
The Evolution of Nitrous Liquid Rockets (UCF)

July 15, 2023 Nitrous Bipropellant rockets have made a resurgence in recent years, thanks in no small part to Half Cat Rocketry. This small two-person operation started out at the University of Central Florida, and after graduating, they have continued their work with autogenous nitrous systems in California. Back at their alma mater, the Knights Experimental Rocketry group have collaborated wi...
Georgia Tech Tests Ever More Powerful Motors with Ambitions of Space Flight (GTXR)

July 9, 2023 Every year, Georgia Tech Experimental Rocketry, a division of the campus's Ramblin' Rocket Club, designs and builds a two stage rocket as part of a spaceshot campaign. This year, the team brought out two "P" class experimental rocket motors to try to fly to 220,000ft. This provides no shortage of power for their latest rocket "Material Girl", and any successes in the flight would b...

The rocket was built and operated by Project Sunride, an emerging team from the University of Sheffield that recently claimed the UK amateur altitude record. Karman Alpha is equipped with two commercial N5800 motors, one for each stage, an...
