Crane Aerospace and Electronics has announced that its SmartStem wireless tire pressure system has been certified for use with Boeing 737NG aircraft. It is already approved for use with the Boeing 747-400, 777 and 787, and with numerous business jet types. The system comprises high-accuracy sensors that replace standard wheel fill stems, and a handheld reader that takes quick and accurate tire pressure readouts without gas loss. The ease and speed of use of the system promotes daily checks, with improved safety as a result, and an increase in tire life. The reader also stores data for longer-term tire health monitoring.
Crane (Booth R91) supplies many systems and components into critical aerospace and defense programs, and many of them are employed in harsh environments such as might be found in engines and landing gear. The company was selected last year to provide the brake and landing gear control systems for the Embraer E2 second-generation E-Jets; lube and scavenge pumps for Pratt & Whitney’s PurePower engines for the Airbus A320neo and Irkut MS-21; and proximity sensors for the A320neo’s engine nacelles. The latter are supplied to Airbus Defence and Space, which in turn supplies fan cowls for CFM’s LEAP-1A engines through Aircelle.
Another important product line for Crane Aerospace and Electronics is the enhanced landing gear control interface unit (LGCIU) for the Airbus A320 family. This senses and reports on the position of landing gear, gear doors, flap disconnect status and cargo door position, feeding data into the central fault display system. The enhanced Crane LGCIU has been standard on new A320s since 2010, but several operators are retrofitting the system to older aircraft. Crane said this week that it is nearing completion of the upgrade of United Airlines’ fleet, while the upgrade of British Airways aircraft is expected to be completed by mid-year.
