Ky Michaelson recently visited Derek Deville and his Qu8k rocket. For those who do not know, this rocket won the 100kft Micro Prize back in 2011, where an amateur had to launch a rocket to >100,000 ft (30.48 km), recover it intact and document it all.
Qu8k achieved this, reaching 121,000 ft (36.88 km). Powered by an O18,000 custom solid rocket motor and at 8″ in diameter reached a max speed of 3200 ft/s (975 m/s).
Charlie Garcia walks us through the design of solid rocket motors in his new YouTube tutorial series.
Video Caption: Hi Rocketeers! In this series of videos I want to teach you how to mix your own professional grade solid rocket motor. Far safer and much more efficient than your typical rocket-candy motors, we’ll explore the intricacies of grain geometries, simulation software, graphite nozzles, and aluminum cases, all while providing links to reputable suppliers. In this episode we’re looking over the design of the grain geometry of our motor, and exploring how to use the simulation software OpenMotor.
As mentioned in a previous post, USCRPL students recently launched and recovered their solid fueled Fathom II rocket from Spaceport America, there was no mention of an altitude at the time of posting but now the numbers are in!
I was recently made aware of Team Ursa, who are building some very cool rockets and hardware and have been doing so for a few years now.
Team Ursa’s mission as stated on their website,
Team Ursa and its partner, Mavericks Civilian Space Foundation, find space exploration to be a potent motivator for students and adults alike. By using the sub-orbital aerospace platform, Team Ursa works with Mavericks to inspire students and communities to invest in STEM through the development of open-source reference designs. These reference designs are intended for the educational and research community’s use to further younger generations’ involvement in STEM, and aid in making sub-orbital space a more accessible laboratory for students.
The team started out as 6 University of Maine senior capstone students who got together to build their first rocket, Ursa 1.0. Ursa 1.0 was a 2 stage solid propelled rocket designed to achieve 100,000ft in altitude, as shown below.
