Design Considerations of the TF34-GE-2 High Bypass Turbofan Engine 690688

The TF34 high bypass turbofan engine is being designed and developed to fulfill the powerplant requirements of the Navy's S-3A (VSX) aircraft. The Navy established specific requirements from the start of the development program to assure that the TF34 meets the very stringent demands of its carrier-based anti-submarine warfare environment. This paper discusses the selection of the optimum engine cycle and the aircraft mission analyses conducted to demonstrate that the selected engine met ASW mission requirements.
