Ceramic cores made with P-52 material from Morgan Technical Ceramics exhibit high dimensional accuracy while maintaining tight tolerances without distortion, and remain stable and rigid at high temperatures, making them suited for investment casting of aerospace engine components. These properties facilitate thin-wall castings, helping manufacturers hold dimensions that were not previously obtainable. The cores can be chemically dissolved after the casting has cooled, leaving a clean air passage replica. The proprietary injection molding process used to create the cores allows high volumes to be manufactured in less time. The process is less abrasive on the molds used to produce cores, which increases their lifespan. The material has improved crushability during solidification—a useful property for alloys that are prone to hot-tearing and/or recrystallization.

After many years of flat-lining in the supply of new commercial jet engines—with improved models, but with designs dating back to the late 1990s, relying on a continuous path of evolutionary development—a new generation of super-efficient powerplants is entering service, introducing many technologies that will also be applied to future engines.
SAE International is working with the joint-venture initiative looking to deploy a high-powered DC fast-charging network for battery electric vehicles (BEVs) covering long-distance travel routes in Europe.
Fuel efficiency—and the economic and ecological benefits associated with it—continues to be the white rabbit of the global aviation industry. While engine builders look toward composites and electrification, and airframe designers toward lightweighting and aerodynamics, engineers at NASA’s Glenn Research Center recently completed testing of a novel concept: the boundary layer ingesting propulsor.
S.S. White Technologies is supplying flexible rotary shafts for the Honeywell Aerospace Air Turbine Starter on the next-gen GE Aviation GE9X high-bypass turbofan engines.
