Enabling Technologies for Nano Air Vehicles
Abstract
This project investigated several areas with the aim of improving performance and operational use of nano air vehicles (NAVs) by understanding fundamental operating principles and developing key technologies. The project developed plasma actuators for thrust and maneuvering control and examined flapping flight through the development of a high speed videogrammetry system and a gust/shear tunnel to replicate flow fields seen as the NAV scale. In the first portion of the research effort, we developed plasma actuators for use as control surfaces, stall mitigation devices and propulsive units for NAVs. Both of these concepts leverage the relevant low speed flow physics experienced at the NAV scale. A secondary objective of this project was to investigate the physics of low speed flow over various biologically inspired aerodynamic configurations, from both numerical and experimental perspectives, and use this information to develop novel yet practical concepts for NAVs. The primary focal points of biological inspiration for this project were the exploration of low speed aerodynamics - particularly separation phenomena - and the physical mechanisms used by nature to optimize performance in this flight regime, including the use of novel plasma actuators, aeroelastic behavior and its effect on gust response and alleviation, and the impact of unsteady motions (flapping) on the flow, especially for the reduction of drag and separation. This was related to the primary objectives of the proposal since plasma actuators are particularly useful as laminar separation control devices.
