The Securing Equipment Computation Utility for Response Estimation (SECURE) Toolbox

An analysis methodology and associated software toolbox is proposed for development that models aircraft/ship securing and deck handling loads in the Dynamic Interface (DI) environment. The software is unique in that it adds both enhanced physical modeling and a novel multibody formulation to the complex computational problem of representing the forces and responses of the aircraft and securing equipment during deck capture, landing and securing operations. The physics models include proper rotor system and fuselage/gear aeromechanical response to ship airwake disturbances and partial ground effects; the multibody formulation uses a unique methodology that results in a reduced number of parameters, thus permitting a wide class of securing systems and constraints to be simulated in real-time; and the toolbox interface provides a 3D interactive environment that allows for user construction of the simulation environment and an immersive mechanism for viewing computational results. The simulation toolbox, hosted under the MATLAB environment, will be validated using data from dynamically scaled models of both rotorcraft and securing systems, tested on an actual ship deck as part of the Phase I program.
