Abstract:
Diamond Back Wing assembly is an assembly mechanism that is attached with UAVs and
some gliding weapons. The primary purpose of the wing assembly is the range
enhancement and providing in-flight stability to the attached UAV. The designed back
wing assembly is basically a modification of an existing model which only has two frontal
wings hence offering less flight time and has concerns related to stability of the wing
assembly.
In this project, we aim to design a diamond back wing assembly that will contribute to
stability and increase the flight range of the attached UAV. The project comprises of
Kinematic and Dynamic Analysis portions where the dimensional design parameters,
components selection and component placement are done based on analysis. Diamond
shaped wing assembly is designed in accordance with the provided parameters. The
diamond shaped assembly includes four wings which increase the wing surface area
providing the lift. The aerofoil selection based on CFD analysis leads us to aerofoil that can
be used for required lift generation that is the primary objective of this process. Selection
of joints between the wings and the sliders are also done keeping in consideration the
options available in the market. The required force/torque parameters for the wing
deployment are calculated and the actuation source that is to be used to provide the power
required for the deployment of wings is also included in the assembly. A small scale
protype with all the actual features in manufactured using a CNC that represents the actual
scale assembly.
The diamond back wing assembly designed could be used with multiple purpose UAVs
such as weapon carrying UAVs, surveillance UAVs and data acquisition UAVs. The key
features of this assembly are compactness and the ability of it to be scaled up and down
according to the requirements.
