Design of next-generation rotorcraft systems
Printer-friendly versionPDF version

Drones and VTOL (Vertical Take-off and Landing) systems, unlike their fixed-wing counterparts, are extremely versatile in application and operate in highly complex, unsteady environments. The design of such systems has to account for and balance a multitude of physics – fuselage/ rotor aerodynamics, aeroelastic and aerothermal effects, noise and vibration, icing, engine integration, fuselage-rotor aerodynamic interaction, transonic and compressibility effects and many more. Recent advances in automated mesh generation, the availability of high-fidelity and fully-coupled physics, and increased computational power are enabling factors for simulation-led, multidisciplinary design of next generation rotorcraft systems. With STAR-CCM+® software and HEEDS™ software, low and high-fidelity, multidisciplinary rotor simulations reduce risk and cost, improve designs faster and enhance operational safety.
