Sikorsky Aircraft has granted a $600,000 contract to Charlotte, N.C.-based Curtiss-Wright Controls for ice detection and protection systems on the S-76D. Under the agreement, which could ultimately be worth more than $12 million with extensions over the next 20 years, Sikorsky will receive two packages—the icing severity detection system (ISDS) and the rotor ice protection system (RIPS)—from Curtiss-Wright Controls Avionics & Electronics (CWC-AE). When used together, the systems detect ice build-up rates and de-ice the blades by activating rotor blade heaters as needed. CWC-AE’s division manufactures the ISDS equipment in Christchurch UK and the RIPS equipment in City of Industry, Calif.
