Liquid Rocket Engine Injector Test Stand Variant 3 Kit with Arduino Mega
Liquid Rocket Engine Injector Test Stand Kit: Simulate LOX/Kerosene Sequencing with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Design and validate liquid rocket engine injector timing without the need for a live test stand. This kit replicates the precise solenoid valve sequencing required for LOX and kerosene injection, complete with real-time pressure sensor feedback, so you can prototype and debug your control algorithms safely at your desk. It’s the same core logic used in static fire test automation, packed into a benchtop instrument you build yourself.
What You'll Build
A fully functional injector test stand that emulates the critical timing of bipropellant rocket valves. The Arduino Mega orchestrates four solenoid channels via relays, reads pressure transients from MPX5700 sensors on the simulated injector manifold, and logs data to microSD with precise timestamps from the DS3231 RTC. The 2.4-inch TFT display plots live pressure curves, letting you observe valve opening/closing dynamics exactly as you’d monitor a real engine test.
What You'll Learn
- Program an Arduino Mega for high-reliability sequential control systems
- Interpret analog pressure sensor data for transient event detection
- Design failsafe relay logic suitable for cryogenic valve simulation
- Build a rugged, expandable data acquisition system for rocketry R&D

Who This Kit Is For
This kit is built for aerospace, mechanical, and ECE engineering students (B.Tech/M.Tech) at IITs, NITs, VIT, BITS Pilani, and private universities who need a propulsion test bench for capstone projects or competition entries like CANSAT and SAE Aero Design. It’s equally suited for rocketry clubs and early-stage space startups validating injector control algorithms before committing to full-scale hardware.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion trained on this exact project; it can walk you through wiring, debugging, and calibration step by step. You can also send photos or queries via WhatsApp and receive direct engineer support within hours.
Can I use this kit to control actual solenoid valves on a live engine?
No — this kit is strictly for benchtop simulation. The relays are meant to drive indicator LEDs or low-power dummy loads, not real propellant valves. It is designed to develop and verify your control logic safely before migrating to flight-rated hardware.
Does the kit include code for the sequencing logic?
Yes, fully commented Arduino sketch is preloaded on the Mega and also available for download. The code includes configurable timing profiles for LOX lead, kerosene lag, and pressure threshold triggers, so you can modify it for your own injector cycles.
What if I want to add more sensors or valves?
The Mega has ample I/O, and the relay module can be expanded. The AI companion includes a section on adding extra MPX5700 channels and writing multi-valve sequences. The enclosure and PCB boards are sized to accommodate modest expansion.
Solenoid valve sequencer controls LOX/kerosene injector timing simulation with pressure sensor feedback.
