Larsen Introduces Amendment to Reduce Growler Noise

Research to Reduce Jet Noise Would Receive $2 Million Boost Under Larsen’s Provision

— from Douglas Wagoner —

Rep. Rick Larsen (WA-02) [Wednesday] announced that his amendment to boost funding for research to reduce jet noise by $2 million has been included in the annual military spending bill.

The Navy is currently researching engine seals – or “chevrons” – which could lead to quieter Growler operations by reducing the harshness of the interaction between exhaust and ambient air. At the same time, Chevrons neither impact fuel consumption nor engine performance.
Supporting research into quieter engines is one aspect of Larsen’s broader, seven-point plan to address the concerns of communities surrounding Naval Air Station Whidbey Island. Larsen’s amendment is a step forward on one key aspect of that plan.

“I strongly support Naval Air Station Whidbey Island and its vital training operations – including carrier landing practice at Outlying Field Coupeville – which make it one of our country’s most valuable naval assets,” said Larsen, a senior member of the House Armed Services Committee. “Initial research into noise reducing technologies has been encouraging and this amendment would send a clear message to the Navy that Congress believes this research should be made a priority.”

If successful, this technology could produce quieter engines for both sailors and families living near bases where these aircraft are stationed.

Last year, Larsen requested that the Congressional defense committees be briefed on the Navy’s efforts to develop noise reducing chevrons for the F414 engine, which powers the Super Hornet and Growler. Over the past two years, Larsen has held public meetings on Whidbey Island and throughout the San Juan Islands to hear directly from constituents on jet noise and other issues.

Larsen was joined in offering this amendment by Rep. Derek Kilmer (WA-06).
