The application of this model to the US Army T700-GE-701D engine is described. Maintenance practices are analyzed to optimize readiness at best value. Engine design tradeoffs are evaluated based on overall Life Cycle Cost. The influence of operating environments is also addressed, such as ...
This paper presents a new approach to the speed control of the T700 turboshaft engine using an adaptive controller of the self-tuning type for the power turbine. For the design of the SISO-STR, a SISO time-series model describing the relationship between the fuel flow as input and power tur...
The Defense Logistics Agency (DLA) awarded GE two contracts in September totaling more than $1 billion to support T700 turboshaft engine fleets across the U.S. military. GE will provide field-level consumables and services through a five-year, $284 million contract with DLA Aviation...
The undesirable engine/airframe characteristics of the HH-60A with the -701 transient droop improvement engine control unit is a shortcoming. The UH-60A with the T700-GE-700 engine demonstrated the largest main rotor speed droop but residual drive train oscillations were small, droop recovery ...
Current practice on the Army's T700-GE-701C engine, used in the Blackhawk and Apache fleets, is to use a mission spectrum, defined in the engine specification, to determine the load profile for each critical component. Fatigue damage rate for critical components is calculated using this ...
