NASA C-130 GOX Project
Nick Mosher, Andrew Bradshaw, Ryan Kraus
At our stay here at NASA, we worked on the Gaseous Oxygen (GOX) backup breathing system for the C-130 aircraft. This aircraft is used for various scientific experiments, and has a non-pressurized cabin and cockpit, requiring a specialized oxygen delivery system.
Above, a diagram of the GOX system can be seen. The parts are as follows:
- Oxygen Cylinders (DOT 3HT) which contain ~76 cubic feet of oxygen.
- High-pressure flex lines, used to transport the oxygen to the manifold.
- High-pressure fill valve, which allows oxygen into the system from an external source.
- Fireproof <metal> Manifold allows flow between the oxygen cylinders and the rest of the system.
- Pressure reducing regulator converts high pressure flow from the oxygen cylinders (up to 1825 psi) into a low pressure environment for breathing use.
- Overboard discharge indicator shows when oxygen is being offloaded for pressure relief.
- Oxygen pressure relief valve releases oxygen in the case of a failure in the pressure reducing regulator.
- Isolation Valve
- High-pressure gauge indicates the remaining pressure in the oxygen cylinders.
- Low-pressure gauge indicates the pressure after reduction.
- 37° Flare Brass TEE connects the GOX system to the LOX system on the C-130.
