ARMY SBIR A152-090: : Linear Inflow Model Synthesis for Advanced Rotorcraft Configurations
TECHNOLOGY AREAS: Air Platform
OBJECTIVE: Develop and validate a method to numerically determine accurate linear state-space inflow models from physics-based aerodynamic models of advanced rotorcraft configurations.
DESCRIPTION: Current linear rotorcraft flight dynamics models are dependent on finite-state inflow theory based on potential flow modeling at the rotor plane . These inflow models have few parameters and are readily available in linear state-space form, making them easy to implement in flight dynamic models for stability assessment and control system design studies. These types of models have been developed for  and extensively used in  modeling single main rotor helicopters. The future Army rotorcraft fleet will include configurations beyond the traditional single main rotor/trail rotor helicopters (e.g., tiltrotors and compounds) and advances in simulation modeling are required.
