Aerodynamics Of Insects
 |
| Title of the Project: |
A web enabled application for rapid estimation of the aerodynamic parameters of fliers. |
| Sponsor of the Project: |
In-house project |
| Objective of the Project: |
The data generated from the study throw light on the flight range, swarming behavior, vectorial capacity, kinetic energy in relation to wing beat frequency etc. |
| Description of the Project: |
Information on the aerodynamic parameters of different fliers will play a vital role in understanding the flight adaptation. |
| Deliverables of the Project - The Solution: |
A user friendly, web-enabled software (WEBAER 1.1) was developed to estimate more than 30 aerodynamic parameters of a given flier. |
| Salient features of the Project: |
- Power requirements like lift and drag can also be calculated.
- The program has provision to calculate wing beat frequency theoretically by using mass flow theory.
|
| Future Spin offs of the Project: |
The study would lead to analysis of certain harmonics of the flight sound have specific response on opposite sex which may help in vector control programs. |
