Computer Modeling and Simulation for Helicopter Task Analysis

Not Available The Navy requires a hybrid fiber optic and electrical rotary joint for towed array applications in passive fiber optic sensors. The requirements of low loss and multiple channel capability in the fiber optic joint combine to make this singlemode design difficult, which explains why no such product is currently on the market. Litton Poly-Scientific pioneered the development of multimode and singlemode single channel and multimode multichannel fiber optic rotary joints in the 1980s, and has been the world leader in electrical rotary joint technology for more than 40 years. In the proposed Phase I program, F&S, Inc. and Litton will combine their technical expertise to develop a hybrid fiber optic and electrical rotary joint based on existing electrical slipring technology at Litton and existing and new fiber optic rotary joint design features. F&S provides the optical design capability, while Litton provides mechanical design capability. The resulting product will be co-manufactured at F&S and Litton, providing commercialization success for F&S and product line expansion for Litton. Due to the critical importance of such a product, cost sharing in Phase I is being provided by Litton, and additional Phase II and Phase III commercialization funding is also pledged.
