Video Caption: WARNING: I was told it’s loud so turn down the volume. Two state rocket more tests at the FAR site on January 5, 2019. First test was a 100 mm seven grain 7615 N-sec KNSB motor with a new lightweight forward bulkhead welded into the motor case with a new titanium nozzle machined by Sugar Shot to Space member Chris Coveny.
The motor failed when the bulkhead gave way resulting in the motor thrusting down into the concrete test stand foundation. That caused the nozzle to be forced up into the aluminum motor case that mushroomed as a result of the impact.
The nozzle was cut from the motor case and used a second time in a six grain 6,900 N-second previously launched flight motor with conventional bolted in bulkhead. This second successful test showed no erosion of the nozzle throat. The nozzle was also cool to the touch soon after firing, something not possible with a steel or graphite nozzle.
Sugar Shot 2 Space (SS2S) are working towards a space shot of an entirely sugar propellant fueled rocket.
Video Caption: Small scale 2-stage Sugar Shot flight for testing our avionics and recovery. Booster performed well and recovered with no damage. The second stage failed to ignite (problem was found and will be corrected. Second stage recovery also successful with no damage. 150 mm ‘O’ impulse motor was successfully launched last June.
75mm second stage was successfully flown several times both as a single stage and as the second stage on a 100 mm booster.
The Havørn rocket is 2.85m long and 0.09m in diameter and is powered by an ‘M-class’ KNER solid rocket motor. The rocket will launch from the group’s purpose-built offshore launch platform in the North Sea.
Check out the group’s website, Facebook and YouTube for more information.
Video Caption: Long time since we posted a video, but we are still going strong. This video shows some of the work we have done in 2017 and until now.
Bugger sums this up!
Video Caption: 150 mm KNSU sucrose rocket motor launch. Motor failed at the bulkhead resulting in a CATO. Friends of Amateur Rocketry test facility, Mojave Desert.
Video Caption: This was the 2nd test firing of the 12 x 44″ KNSB static test fire motor for the Sugar Shot to Space project. The first firing was using two 12 x 20″ propellant grains each weighing 132 pounds for a total propellant weight of 264 pounds. This test was using three 12 X 13″ propellant grains, each containing 85 pounds of KNSB sugar propellant.
A nice overview video of USCRPL’s Fathom II launch from back in March showcasing prep, launch/flight, and recovery. The team set a record for student built rockets.
Video Caption: On March 3rd, 2017, University of Southern California Rocket Propulsion Lab launched Fathom II, a sub-scale model of its space-shot vehicle in Spaceport America, New Mexico. Fathom II reached 144,00 ft at apogee, taking the record for highest student rocket by almost 50,000 feet.
In what is possibly a first, the MIT Rocket team have successfully tested a fully 3D printed solid rocket motor. The motor which included everything bar the propellant was printed from Nylon.
Be interesting to know the cost, let’s say vs a hobby motor of the equivalent size.
Check out the video below and read the full write-up here.
Video Caption: Using Markforged Onyx Nylon a 2 piece, completely 3D printed rocket motor was fired for the first time by MIT Rocket Team on April 21.
Without the generous support of Markforged this project would not have been possible.
