Implementation of Actuation Subsystems in a 6DOF High-Speed Vehicle Simulation

Quantifying the actuation power requirements and thermal outputs for a runway takeoff electrified high-speed vehicle is essential to consider when designing the geometry, trajectory, power generation and thermal management systems. The earlier this can be done during the design process of such vehicles, the more optimized the system will be, which is desirable due to the difficulty in achieving such high-speed vehicles. The actuation power and thermal profiles are not often simulated at the conceptual design level due to the considerable work required to develop a controlled 6DOF simulation before the actuators can be analyzed. From the previous chapter, a workflow to obtain such a simulation at the conceptual design level for a notional high speed vehicle was created, presenting the ability for actuation integration. Electromechanical Actuators (EMAs) were implemented into this model, and controlled to meet MIL-STD-1797A flying requirements. A power and thermal analysis was preformed for the subsystem, and the resulting quantities characterizing the power requirements and the thermal profiles were implemented into the SIMULNK model. Upon simulation, the power and thermal profiles for the actuators of each control surface were available for analysis.
