Aerodynamics of porous wings for unsteady load alleviation of micro aerial vehicles

The present project aims to investigate how to mitigate load fluctuations by exploiting wing porosity. This will be achieved by taking inspiration from the feathered wings of birds, the bristly wings of insects and the filamentous wings of plant seeds. For example, the dandelion fruit, which exploits the energy in the wind fluctuations to travel hundreds of kilometers remaining airborne for several days, adopts wings made of 90% empty space (Nature 562:414-418, 2018).

Specifically, the objectives of this proposal are as follows.

  1. Familiarise with the literature on natural flyers with porous wings and previous attempts to exploit wing porosity for enhanced aerodynamic performances of manmade wings.
  2. Familiarise with the research methods and approaches to unsteady aerodynamics, particularly with the impulse method based on the analysis of the vorticity field.
  3. Apply the impulse method to canonical flows (J. Fluid Mech. 870, 492–518, 2019) and investigate the effect of wing porosity.
