Start Up Shut Down System

Honeywell Aerospace (Southborough, MA)

Problem:

For an upcoming project, Honeywell Aerospace needed a device which would be able to fuel the hydrogen generators which powered the drone, at the testing airfield.
The device needed to be portable and have access points to a tank of hydrogen and a tank of nitrogen.

Objective:

Create a P&ID document first outlining how the apparatus would be created and what fittings, valves, gages, and regulators it would consist of.
Order 3D printed parts as well as off the shelf items to complete the assembly.
Build the assembly keeping pressure safety tips in mind.
Test for leaks and perform a final walkthrough of the assembly.

Process:

Created a P&ID with insight from Honeywell managers and careful research into specific products to provide an overall system outline.
Upon review of the P&ID, built the system according to standards required by the division by first creating a 3D model, ordering necessary parts, and finally assembling the design with machinery and hand held tools.
Tested the final assembly with leak test techniques and proper testing procedure first at low and then at operating pressures before replacing any leaking or faulty components that did not pass inspection.

Learned how to use medium level machine shop tools such as a sheet metal cutter, bender, and chop saw.
Learned how to depressurize a system and vent the system completely from high pressure gas.
Gained experience in how to cut and bend stainless steel tubes as well as assemble and disassemble Swagelok compression fittings.
Once this project was completed the team was able to utilize this device to fuel the drones in a portable manner.
