Incorporating a full triplex redundant hydraulic actuation system the Fly-By-Wire V-280 Valor is Bell Flight’s next-generation tiltrotor designed for the Joint Multi-RoleTechnology Demonstrator (JMR-TD) program. The hydraulic systems were developed by conducting component and system level analysis in parallel with the broader design process. This parallel effort ensured that the hydraulic systems would meet not only technical performance requirements but also achieve program goals for cost and schedule. Hydraulic system performance was evaluated in several areas including Hydraulic Line Sizing, Thermal Performance and the Evaluation of Integrated Subsystems. The hydraulic system sizing iterations used a combination of steady-state spreadsheet-based analysis and dynamic system-level analysis to achieve the necessary power delivery and thermal performance for the aircraft. The complete hydraulic system architecture maximizes performance while achieving minimum weight, cost and development time.
