FRCSW Revamps Super Hornet Windscreen Production

A project in the Fleet Readiness Center Southwest (FRCSW) canopy shop that began in June 2017 to address occurrences of delamination in some windscreens of F/A-18 Super Hornets has come to an end.

Components production manager Jakob Grant said that fleet back orders for the windscreens had reached about 40 last year prompting FRCSW artisans and engineers to apply their expertise and ingenuity to craft a solution.

“Working together with the sheet metal artisans in the canopy shop, the machinists, painters, and the evaluation and examination teams, engineering embedded itself into the paint and sheet metal shops and worked side-by-side with them to develop local engineering specifications (LES) to measure the coating that is used on the windscreens and to streamline the process,” Grant said.

To improve the paint process, materials engineers determined the requirements for measuring the density and thickness of the low-observable coatings that are applied to the windscreens.

An initial LES for the repair and replacement of the transparencies (the actual glass which is made of polycarbonate and acrylic plastics) was also developed.

“The coating process in the painting area was our main development and deviation from our regular procedure, and because of the additional requirement to measure the density and thickness of the coating, it went from a 13-day process to averaging a 26-day process in paint,” Grant said.

“This also caused some of the backlog because it was taking us twice as long to meet the engineering requirements which had become more stringent, and to still meet fleet requirements.”

Nevertheless, team efforts enabled the canopy shop to produce 31 windscreens during the first quarter of fiscal year 2017. The shop is on track to produce the same amount for the second quarter.

“For three months we worked to streamline procedures, and in early October, we were able to meet fleet demands of 10 windscreens per month. During that time, we had to work with engineering under temporary instructions to get those 30 windscreens done,” Grant noted.

Windscreens are turned in from the fleet as repairable units. Upon induction they are cleaned and prepared for disassembly by the shop’s artisans in Building 250.

“We remove the fasteners and sand and prime the windscreens,” said sheet metal mechanic Loc Yu. “Afterward, the windscreen is placed in the fixture where we install new glass and seal the seams. All of this takes about five days. Then it moves to paint in Building 472 before being reissued to the fleet.”

Canopy shop work leader Eugene Ellis noted that the shop uses continuous process improvement measures on windscreens and Hornet canopies.

“We have a single piece flow system that results in less waste of materials and sealant, and fewer defects. In turn, this increases our production quality and results in less rework. Our ultimate goal is to extend the service life of the windscreens and improve production to the fleet,” he said.

FRCSW is the only naval facility that refurbishes Super Hornet windscreens.

The new plating furnace offers a higher component capacity than its predecessor and can complete the cadmium coating process in approximately half the time.

FRCSW Fires Up New Cadmium Plating Furnace

To help ensure its cadmium-plated aircraft parts are manufactured under the highest possible standards, Fleet Readiness Center Southwest (FRCSW) replaced its 45-year-old cadmium plating furnace with a new computer-aided design (CAD) model.

The new furnace, which arrived in the plating shop in Building 472 on Dec. 5, can accommodate parts as small as bushings to components of up to 5 feet in length by approximately 2 ½ feet in width.

Unlike its predecessor, the new furnace has two holding racks: one stationary, and the other with an option of motion that ensures a more even coating process.

“Not only does this new one have a higher component capacity, but it can complete the coating process in approximately 50 percent less time,” said Martha Hoffman, Capital Investment Program (CIP) project manager. “The old furnace required the operator to remove and turn the components as part of the coating process, which can add up to an additional 30 minutes to the overall procedure.”

FRCSW artisans underwent a five-day operator training seminar by Tito Visi, president of V&N Advanced Automation Systems, manufacturer of the furnace.

Training included the use of the unit’s 500-gigabyte computer/control panel to input production commands and print reports. The CAD system is user-friendly, operating through common programs like Microsoft Word™ and Excel™.

A successful cadmium coating procedure is dependent upon a variety of requirements, Visi noted.

“The fewer molecules of air you have in the chamber, the better coating you are going to have. So for this, we have a mechanical pump and a booster pump which brings the atmosphere to a regulated air pump (RAP) vacuum,” he said.

“We bring the pressure down and when we hit the base pressure needed for the coating, we are able to evaporate the material (cadmium) to stick to the part. That takes around 20 minutes. Then, argon is introduced to cool down the part which eliminates any contamination. We don’t use oxygen or air, because the part could oxidize.”

When complete, the part is removed and moves on through the plating process.

Costing approximately $990,000, the new furnace will not only be used to coat F/A-18 Hornet and E/2-C/2 aircraft parts, but LM2500 engine parts, as well.
