Integrated System Build & Test
Table of Contents
Project RecapA hybrid rocket engine is a device that is used to propel an object, generally a rocket, to a user specified point in the atmosphere. The engine can achieve this by converting the chemical energy of the propellants into thermal energy, and ultimately converting that into mechanical energy that imparts a change in momentum on the rocket. The hybrid engine differs from other engines because of the fact it uses a liquid oxidizer, with a separate solid fuel. Separating the fuels makes it inherently safer to store and operate than a traditional liquid or solid motor. The purpose of this project is to build a custom hybrid engine test stand for RIT Launch Initiative to launch a rocket to 30,000 feet at the 2019 Intercollegiate Rocketry and Engineering Competition (IREC). The test stand must be built to withstand the pressure and thrust of the rocket, as well as the cold and hot fire tests that the rocket must go through in order to be launch ready. It must be safe to handle, reusable, high performing, environmentally friendly, and comply with all IREC and government regulations. By year's end, the engine must be ready for tests like the static hot hire test, cold flow test, proof pressure test and system leak test in the bunker on RIT’s campus.
Team Vision for Integrated System Build & Test PhaseDuring this phase, the team worked to finalize tests on the individual subsystems, as well as begin integration and running testes with the integrated systems. Late deliveries on products has caused this section to be slightly delayed.
In particular, the team focused on:
- Constructing and Analyzing Subsystems
- Testing and Evaluating Subsystems
- Preparing all Systems for Full Functionality
- Integrating all subsystems with the full system
Mechanical System Updates
- All material stock has been received.
- Clamp parts have been cut by water jet.
Mechanical System Next Steps
- Fasteners need to be purchased.
- Clamp parts need to be refined by mill, like ID of clamp to be 6.55" and hole extrusions for bolts and bearings.
- Measure k-value of spring for pre-load system.
- Machine adapter ring and force plate.
Electrical and DAQ Systems Updates
- DAQ system is calibrated and ready for mass flow rate sensor, as well as the accelerometers.
- The NI-cDAQ system will be in the bunker, and encased in a bud box. This will prevent any damage to the device, and is cheap to implement.
- A computer will be provided by RIT to run the LabView software and record data.
- Wires for sensors have been soldered, hardened, and tested with hardening equipment.
