Summary

I led the engineering design and field installation of a 30-ft aerosol inlet for a remote mountaintop lab at Powder Mountain, Utah, and I delivered the system on a four-month timeline. For the winters of 2025 and 2026, this inlet will be supplying ambient mountain air to multiple instruments that are collecting data to study the impacts of cloud-seeding in the Wasatch Range.

I collaborated with aerosol scientists to iterate quickly on requirements, and I maintained an active and respectful relationships with our University machine shop to refine drawings for manufacturability so parts could be produced reliably and with our rushed schedule. I also designed the support and anchoring approach to keep the ~150-lb inlet stable in harsh winter conditions and wind speeds above 100 mph.

During installation, I worked closely with local technicians to install the inlet to the roof of the container, and I physically built, aligned, and fastened the inlet and support structure, as per my design specifications. Of course, as is expected with any fieldwork in the mountains, I was constantly needing to quickly react and solve unexpected field issues quickly to keep the system safe, serviceable, and sampling-ready.

Inlet build highlights

Custom manifold design for high-integrity aerosol sampling

The inlet manifold was designed to deliver ambient air to multiple aerosol instruments while minimizing particle losses. The concept intentionally mirrored proven research inlets at the University of Utah (William Browning Building rooftop inlet) and Storm Peak Laboratory, but was adapted for a remote container deployment and improved flow distribution. A key enhancement was an alternating outlet pattern that spreads flow more evenly—improving delivery efficiency across ports.

Because this project ran on a tight 3-month timeline, I partnered closely with a machine shop to rework the original inlet design for fast, repeatable manufacturing. Instead of complex fixtures and manual tooling that could introduce obstructions to inlet airflow, we used custom precision-machined inserts that could be easily welded to the pipe. That approach was time efficient, while also mitigating risks of human error during the machining process and providing improved dimensional control.

This full design assembly view shows how the inlet was engineered as a modular system. The manifold distributes flow inside the container, while a roof bulkhead fitting both seals the penetration against snow/ice/water and supports the vertical load of the inlet. Above the roof, two modular 10-foot inlet sections extend the sampling point beyond local contamination near the container and into cleaner atmospheric flow (and cloud/fog conditions). The inlet head pulls in ambient air and incorporates heating features intended to prevent icing during winter operations.

Support strategy: concept iteration under real site constraints

The 30-ft inlet weighed approximately 150 pounds, and 20 ft of the inlet needed to extend above the roof the container. Furthermore, the container would be stationed on a summit of Powder Mountain Ski Resort, where winds have been recorded above 100 mph. Beyond the structural needs, the inlet needed to be installed in an appropriate position, so that instruments could be placed around the inlet, as close as possible, to minimize particle loss.

As the lead on this body of engineering work, it was necessary to communicate concepts to the larger team of managers and scientists effectively using SolidWorks modeling. I first made detailed measurements of the shipping container and the instruments that would need to be installed. I then iterated through several support concepts, as per my own independent research and by connecting with local millwrights and several mechanical engineers within my network to gain their respective insights.

Design iteration 1: Rohn tower concept requiring concrete base

Initial approach: leverage known Rohn tower installation practices to support the inlet. However, concrete footings were not permitted on our site location

Concept — Rohn tower + Concrete Foundation
Design iteration 2: above-ground ballast approach for tower support

Constraint-driven iteration: Generated a lightweight ballast system that utilized the fork ports at the base of the container

Concept 2 — Rohn Tower + above-ground ballast
Design iteration 3: guy-wire concept with clean, self-contained load path

Final strategy: self-contained anchoring to the container.

Concept 3 — guy-wire system (final direction)

Ultimately, the team decided the guy-wire system anchored directly to the container would be most appropriate. That decision created three urgent engineering needs as the schedule tightened: (1) a container anchor system to hold the guy wires to the container's four corner castings, (2) safe, non-slip clamp system onto which the guy wires would fasten to the inlet, and (3) a vertical load support solution, since guy wires stabilize laterally but would not carry the inlet’s weight.

Challenge 1: anchoring guy wires to the container

The anchoring approach needed to convert high lateral loads from wind into a clean load path from the guy wires and through the container’s corner castings. The corner castings were quite bulky, so a typical shackle system was not possible. The final hardware was effectively a modified U-bolt, designed to be simple and strong and needing minimal machining work.

Challenge 2: attaching guy wires to the inlet pipe

Because the guy wire support system was not the original plan, the inlet was not inherently designed or built to interface with guy wires. I designed and built a custom pipe-clamp-mount, that would hold tight to the inlet diameter and attach to the four guy wires running to each corner casting. Because the inlet would be in cold and windy environments, I had beads of weldement added around the circumference of the inlet to mitigate any risk of the clamp becoming loose and slipping down the inlet.

on-site, we found that we could simplify the design to reduce the weight of the clamp system, which is what is pictured here. Success!

Challenge 3: supporting inlet weight + sealing the roof penetration

In reaction to the new challenge of needing to support the weight of the inlet and downward force of the tensioned guy wires, I quickly designed and rush ordered a custom seal and support assembly. I ensured the assembly only required basic machining practices and could be manufactured and installed quickly, but also meet appropriate structural requirements.

Heated Inlet Concept Generation

I also developed a heating approach aligned with aerosol inlet standards (e.g., WMO-GAW / ACTRIS-style guidance) to prevent icing while protecting sampling integrity. Although we ultimately did not execute this design initially—because tariffs and supply chain disruptions pushed the preferred heating elements to long lead times—I delivered a complete concept and analysis that could be implemented later without redesigning the system from scratch.

Field installation

On-site build, alignment, and commissioning

The field work required fast, high-quality decisions in winter conditions. Key mechanical challenges included positioning and aligning the inlet, sealing the container, validating and reinforcing the stability of internal and external support structures, plumbing the air to an outlet of the container, positioning the instruments within the container around the inlet, and keeping the container sealed and serviceable between site visits while scientists began commissioning their instruments in parallel.

Here, I have included two photos of the inlet after it had been lowered by a crane to the roof of the mobile lab.

In parallel to the inlet being designed and built, I helped transfrom the shipping container into the serviceable lab that it is today: planning instrument placement, cutting penetrations, crafting unistrut framing, routing the inlet through the interior, and building an ergonomic layout that supports both performance and maintenance.

Team Communication

Shown here is an early installation of an instrument that measures ice-nucleating particles, positioned near the base manifold of the 30-ft inlet. Close coordination with scientists was essential to ensure that on-site engineering decisions aligned with instrument requirements as commissioning began in parallel.

In the early stages of the project planning, I also led many of the discussions where I shared possible floorplans for the lab using SolidWorks and the team decided how they wanted instruments and the inlet positioned in the lab.
