I’ve managed to get my final year project to be based on rockets, what’s more a guided rocket! The project has a few key areas: Airframe construction, IMU and simulation/control. I chose to use canards for a few reasons: They can be used over the entire ascent of the rocket not just the motor burn, …

Adapted from a page by Adam Greig 14/08/2015. This post provides links to more information about the radio transmissions from Martlet 2, such that they may be publicly documented formats. For details on the physical radio modulation and data link layer, please see:https://github.com/cuspaceflight/m2-electronics/blob/master/docs/radio.md For details on the packet structure, please see:https://github.com/cuspaceflight/m2-electronics/blob/master/docs/telemetry.md For any other queries …
The flight computer PCBs have been collected from Cambridge Circuit! As ever they’ve done a fantastic job. We had a quick tour of their facility when we collected these PCBs which was great to see. Thanks again Cambridge Circuit! The renderings of the PCB above were generated by GerbLook, click the link to check …
Martlet 2 is powered by an O-8000 Pro150 Cesaroni motor. This is the largest certified motor available and, over the course of its 5.12s burn time, produces an average thrust of 8000N. We purchased the motor last weekend from Animal Motor Works and will be meeting it for the first time at BALLS. In other …
Today Cambridge Circuit Company finished manufacture of the PCBs for M2R, the radio board on Martlet 2. We drove over to pick them up this afternoon and they’re looking good! Hopefully we’ll have the designs for the flight computer finished soon and then we’ll get both boards assembled and start on the firmware. A big thank …
The radio modules we’ll be using on the M2R radio boards arrived from Radiometrix today. They’re generously sponsoring Martlet 2 with these radios, thanks! We’ve been using their radios for many years now, starting with the venerable NTX2 for some early high altitude balloon payloads, and they’ve always performed perfectly. We’re excited to try out …
Today we finished the PCB design for the radio system on Martlet 2. You can read more about the board here, or check out the schematic here. Our designs are made using KiCAD and as ever you can view all the gory details on our GitHub. A big thank you to our sponsor Cambridge Circuit …
A couple of weeks ago we received the first components of the Martlet 2 airframe. These roll wrapped carbon fibre tubes have an inner diameter of 182mm and a 2mm wall thickness. They were bought ‘off-the-shelf’ from a UK company and look great! Both need facing off to ensure the top and bottom surfaces are …
After many weeks of careful planning and design, lots of simulations and calculations, and pages upon pages of datasheets, the first revision of the design for the flight computers aboard Martlet 2 are complete. You can check them out here: m2fc is the main flight computer and m2r is the radio board. Since the radio board is the simpler …
We went to the March EARS Launch Day. We launched two rockets: Pulsar, a kit built by freshers last term, and Isis, a rocket built last year. Here’s Pulsar going up on a G-motor: And here’s Isis on a 4-grain I:
