BPS recently tested out a new experimental rocket motor from Aerotech, a G8ST. Producing an average thrust of 8.3N for 17.7s, this was the perfect motor for testing the in-house designed and built Signal avionics TVC package.
Revision 2 of the avionics is now available to buy, so if you are wanting to take your rocketry to the next level, you’ll need this package to guide you!

A quick note: While the motor did melt the PLA tube holding it, the rest of the TVC assembly(outer/inner gimbal, servos, linkages) were unaffected. Since the heat of the motor was so intense, it’s unlikely we’ll be able to mitigate it using more liners than were already there. The same goes for using most other plastic FDM materials. For now, we’ll probably cut the burn time down a bit and make sure users have access to extra motor mount tubes, should one of them melt. The motor tubes are incredibly easy to manufacture and replace, and the priority right now is ensuring Signal’s software and UX are top notch.

A model Falcon Heavy with landing gear, gimbaled engines and a flight computer that will enable it to propulsively land! Yep you read right!
Joe Barnard of BPS, known for the development of the Signal Avionics, a thrust vectoring (plus lots more) flight computer for hobby rocketry, has been making a FH rocket!
No better way to test the avionics than on a three core booster, complete with hold down clamps and all!
Looking forward to seeing this fly!
Signal Alpha is now available from BPS (albeit you will have to wait till the new year for the next shipment). Not sure what Signal Alpha is? Well, in short, it is a thrust vectoring kit for model rockets and has a huge cool factor!
(Read more about it here)
To go along with your purchased kit, Joe of BPS has made the below instructional videos to help you set up and fly your first guided (finless) rocket. Unfortunately, it is not available outside of the USA (yet!), but if you are there I suggest jumping on the next batch and take your model rocket flying to the next level!
Watch the video’s below, it looks like a lot of fun to be had, kinda jealous until I can grab one!

Two great flights! The second flight had lots of wind to fight against, hence the wiggle near the end. The nose cone was 3D printed, and the stress of chute ejection broke the plastic connecting it to the shock cord.
Flown at the CMASS/MMMSC club launch on October 28th, 2017.

Joe Barnard of BPS has just released his Signal Avionics flight computer and it is full of cool features that any amateur rocketeer has been waiting to see!
This is no normal flight computer, Signal Alpha is a full thrust vectoring kit which essentially enables you to fly your rockets with gimbaled engines and no fins! Imagine the possibilities now open to you for experimentation in your park.
Joe does a much better job explaining all the features in the video below but for USD$299 you cannot go wrong for what this little board can do.
I look forward to it being ITAR friendly so I can get my hands on this gem!

It seems everytime I post about Barnard Propulsion Systems, Joe has gone off and succeeded in carrying out another flight! This time Scout was launched off vertical and brought back to the correct orientation.
Joe is also about to start selling the amazing little flight computer that does all this as well! Get your name on the list to be one of the first to grab it! https://www.bps.space/signal#signal-avionics
Video Caption: Running Signal’s course correction feature, Scout launched angled roughly 15 degrees from upright. Course correction held the vehicle orientation off the pad after launch, then plotted a smooth maneuver back to upright. As shown here, corrections are determined in a global reference frame, then executed in the local frame, meaning roll is not an issue(until the TVC hardware cannot keep up with the roll). Once deployed, the parachutes broke the kevlar reinforced shock cord, separating them from the body. The cord snapped at a weak point where significant heat had been experienced during assembly, which can be avoided next time with a new cord and some epoxy. The flight computer and TVC mount remained entirely unharmed by the impact.
