Pratt & Whitney is modifying the lead engine for the U.S. Defense Department's F-35 Joint Strike Fighter to address an erosion problem that surfaced in the propulsion system almost two months ago.

The company is increasing the size of the "restrictor plate" that regulates the flow of cooling air in part of the F135 engine, Pratt & Whitney spokesman David Morgillo told The DAILY Aug. 4. Engineers determined that the plate's old "undersized" design was not allowing enough cool air to reach the second-stage vanes of the turbine section, causing erosion to develop in the FX641, one of four F135s the company has delivered to the JSF program.
