Multidisciplinary Design & Modeling — UAS ADS

UAS ADS, developed in-house, provides a robust framework for configuring and designing diverse aerospace systems. The platform enables rapid evaluation and optimization of aerodynamic properties, propulsion systems, structural loads, and subsystem integration. The aerodynamic modeling process accounts for the effects of laminar-turbulent transition on lifting surfaces, ensuring that key influences on lift, drag, and aerodynamic stability are reflected in the results. This capability, rarely available in standard design tools, is critical for reliable performance estimation and effective flight control development. UAS ADS generates comprehensive aerodynamic databases and control derivatives, fully compatible with UAS^Pro5 for seamless simulation and validation. Calibration with CFD or wind tunnel data is standard practice prior to critical design reviews

High-Fidelity 6DOF Simulation — UAS^Pro5

UAS^Pro5 operates as a nonlinear six degree-of-freedom (6DOF) simulation environment for accurate modeling of aerospace system dynamics and performance. The simulation supports geocentric and local coordinate systems with quaternion-based kinematics, providing high numerical accuracy and real-time performance for engineering development and embedded code integration.

Detailed modeling of VTOL (Vertical Takeoff and Landing) dynamics is implemented, including real-time calculation of propeller thrust with consideration for angle of attack, sideslip, flight speed, and propeller tilt. The aerodynamic interaction between propeller downwash and wing surfaces is modeled to address transition flight phases, which present known challenges for fixed-wing VTOL development. This fidelity supports reliable prediction of system behavior throughout all flight regimes.

Simulation features include:

• Propulsion modeling for electric and combustion engines, including dynamic propeller behavior and folding/tilting mechanisms

• Full inertial modeling with dynamic center of gravity and detachable payloads

• Servo and actuator dynamics with fault and failure modes

• Sensor and gauge simulation with configurable errors and latencies

• Environmental modeling for winds, gusts, atmospheric conditions, and ground effects

• Support for SITL/HITL integration to test embedded flight control software and ground control stations
