OUR TECH

Here you can learn about some of the technologies and components on our rockets. The majority of these examples have been used on our largest and most advanced rocket yet, the Sporadic Impulse, from EuRoC 2022. Follow along as we update with technologies we are developing for Nimbus.

Our 1st generation throttleable hybrid engine system used to propel Sporadic Impulse. The engine consists of a steel frame, a paraffin fuel grain in the thrust chamber, a graphite throat insert and tufnol as an ablative throughout. The engine’s performance was optimised over the course of 8 hotfires prior to EUROC 2022.

Our payload system for Sporadic Impulse at EuRoC 2022. It consists of a 3U CubeSat structure, and a recovery parachute integrated with fabric solar panels. The parachute was tested earlier in the year and proved successful in generating electrivity upon decent. At EuRoC, we are expecting a repeat of a successful recovery for furhter improvement in future rockets.

 

Our avionics bay. Consisting of 6 SRAD PCBs (pickles), including Pickle Rick, Flint & Steel, Kermit, Chad, Lightning McQueen and others. This first iteration of our modular electronics system, allows for an easily configurable avionics system for any of our rockets.

Pickle Rick is the flight computer, consisting of telemetry, GPS, and receiving and handling commands. Flint and Steel is the ignition controller which fries electronic matches to ignite the rocket engine and deployment/separation systems. Kermit is the sensor board which handles the engine sensors for applications like temperature, pressure, and weight readings. Chad is the valve and motor controller, it controls the engine valves in order to fill and vent the tanks. Lightning McQueen is the power distribution unit which manages the batteries and rocket power including logic and deployment. 

Our in-house devleoped spring loaded seperation system. It utilises the energy stored in the springs to provide enough force to separate the tubes with minimal electrical power input.

An essential load bearing part created using generative design. Metal additive manufactureing was used for this aluminium component. It serves to transfer the load from the skeletal structure in the lower airframe to the rocket fuselage in the upper airframe. Compared to its original version, the final version removes more 61.9% of the mass.
