"This is a great example of how the naval science and technology community delivers affordability along with cutting-edge results," said Vice Adm.
An F-35 canopy-the term used to describe the transparent enclosure over the cockpit-has an unusual shape and specialized material that make the manufacturing process more complex than that for other aircraft.
Now what used to take up to six days to make will take only four days or less. The new automated process also will require fewer tools and help avoid costs when aircraft require replacement canopies.
Currently, skilled technicians load a preformed acrylic shell into a forming tool and put it in an oven where it heats at 200 degrees or more for up to six days. During that time, workers regularly enter the oven to observe the canopy's progress and manually adjust positioning clamps to control the forming process. Managing this process is critical for optimal canopy performance.
The new cost-effective method employs a control system with four cameras that can see inside the oven to calculate the rate at which the canopy's shape is forming. The clamps then automatically adjust to ensure the shape remains uniform throughout the process to meet the F-35's stringent performance requirements.
"We took an intensive, manual, time-consuming process and improved it to be more precise and efficient," said
The new method supports the Chief of Naval Operations' Navigation Plan that calls for the service to continue efforts to make investments to address near-term challenges and develop future capabilities even in the face of budget constraints.
