March 16. The famous company Pratt & Whitney decided to redesign the F135 jet engine, intended for a fighter F-35 Lightning II... This was required after the destruction of the blisk during testing last December. By that time, the engine had worked 2200 hours, which is equivalent to 9 years of operation. Blisk is a turbine in which the blades are integral with the rotor disc. Now engineers at Pratt & Whitney are busy researching the collapsed part.

During the redesign on Bliss, hollow blades will be replaced with all-metal blades, thus increasing the reliability of the part. True, the mass of the engine F135 because of this will increase by 2,7 kilograms. But such all-metal blades blizka significantly simplify and reduce the cost of production of engines. After the redesign, the details are planned to be installed on the F135 engines absolutely for all versions of this fighter.
