- Description
- Innovative design of helicopters promises great benefits over conventional aircraft but there are a number of technical challenges. Hyper Q Aerospace brought a project to the 2020 Mathematics-in-Industry Study Group to consider a helicopter design with a counter-rotating, coaxial, double rotor. Specific considerations were the vibration and harmonic properties of the rotor blades, the noise from the aircraft and the aerodynamic characteristics. Euler--Bernoulli beam theory and classical airfoil theory were implemented to consider the vibration and aerodynamic features of the aircraft and the rotor system. The fundamental lengthwise and lateral harmonics of the blades were obtained and compared with typical rotational forcing frequencies. The modification to the lift generated by the counter-rotating blades and noise mitigation strategies were discussed. Improved design strategies were presented.
