Passive Noise Reduction
Dotterel's award winning passive noise reduction UAV propeller shrouds offer next-level optimised design as well as fully customisable options.
Noise reduction and safety shrouds
Dotterel's noise reduction and safety shrouds reduce noise created through the complex interaction of many mechanisms. First the noise created by the propeller is reduced, then remaining noise is reflected up, away from people below, and specific tonal frequencies are absorbed in the core made from a protected laminate of acoustic materials.
Powerful modelling and simulation
Shrouds are modelled and performance simulated to meet specific requirements. The shrouds increase thrust to offset some of their weight penalty. The thrust, weight, flight maneuverability objectives, along with motors, controllers, and frame design are all factored into final shroud and propeller designs.
Optimised for your UAV platform
Shrouds can be retrofitted though performance is improved if they are designed in from the start. We work with UAV manufacturers to meet solution objectives and optimise the design.
We also collaborate extensively on exploring new challenges in the field. Working with customers, external researchers and academic institutions to keep at the forefront of noise reduction.
