mojaverockets
Published on Nov 11, 2016
A 4" (100mm) 'K' impulse 2-grain sugar motor. The airframe was made from salvaged and scrounged materials from other rockets. The propellant was KNSB with a 1" (25mm) core. Launched November 5, 2016 from the FAR site, Mojave Desert.

World's largest sugar propellant grains and 3rd flight of the phoenix rocket
mojaverockets
Published on Dec 5, 2016
Casting the second 12" x 20" (300mm x 500mm) sugar propellant grain at the FAR site. Each grain will have a 3" (75mm) core and approximately 130 pounds (55 kg) of propellant with an expected motor burn time of 16.7 seconds. The Phoenix launch was a small 100mm 2-grain sugar motor with 1" (25mm) cores used for inexpensively flight testing propellant, electronics and other components. Each Phoenix flight cost three dollars...what a bargain!

FAR Oct 21, 2017 sugar launch
mojaverockets
Published on Oct 22, 2017
On Saturday, Oct 21, 2017, students from Western Center Academy attended a free sugar propellant class held at the Friends of Amateur Rocketry facility in the Mojave Desert. After making 4" (100 mm) grains, a static motor test followed by a successful launch and recovery of the rocket was completed. The rocket reached an altitude of 5,915' ( 1,803 m) on $5 of KNSB solid propellant.

One of these days someone will start up an additive manufacturing rig for KNSB motors, and will start getting great repeatable flights for cheap

Since this last post, we have successfully flown several 3", several 4", a 2-stage 4" to 3", a 6" and successfully static tested two 12" sugar motors with 18 second burn times at nearly 2,000 pound average thrust without a single failed motor.
We have a 2-stage 6" to 3" planned for next week.

Sorry, Rick. I've noticed recently that YouTube email notifications are not all arriving. After searching thru subscriptions on YouTube directly I noticed that many new postings are there that I didn't get notified by email. I'm now double-checking manually the YouTube subscription link in addition to email notifications. Thanks for pointing the missing video out. Tony.

Instant on sugar PVC rocket motor
mojaverockets
Published on Jan 31, 2018
3" ( 75 mm ) sugar propellant PVC motor case rocket. Chris has been working on 3 and 4" ( 75 & 100 mm ) sugar motors as a possible strap-on booster for the Sugar Shot to Space project with the goal of reaching space on a rocket powered by sugar propellant. Since the rocket is unguided, the strap-on boosters in development will have to have instant ignition and uniform thrust & burn times.

What was the date of the firing in the video?

For those that are unaware - some background.
http://www.nakka-rocketry.net/This most excellent site goes into various tests, has computations of rocket designs, comparisons of propellants - KN/sucrose/dextrose/whatever - designs, and some theory.

CATO in this context? (JATO is Jet Assisted Take Off but I am at a loss)

Short for "catastrophic failure" ...
